    The Ultimate Doom:
    The Ultimate Doom, or most commonly known as Doom, has been around since 1993.
    This game provides majority of the weapons and enemies for the later
    installments (included).
    
    Doom II:
    Doom II is the sequel to The Ultimate Doom. This sequel was released in 1994.
    This game included more enemies and only one more weapon. All of them are
    included in this guide.
    
    Final Doom:
    This is split up into two different games, TNT/Evilution and The Plutonia
    Experiment. This game was released in 1996. All the enemies and weapons are
    passed down from Doom II. The only difference is, you guessed it, the maps.

    --------------------------------------------------------------------------------
    
    5.) Enemies
    ----------------------------------------
    Former Humans: Just a few days ago, you were probably swapping war stories with
    one of these guys. Now it's time to swap some lead upside their head. They are
    the weakest of all enemies.
    
    Former Human Sergeant: Same as above, but much meaner and tougher. These walking
    shotguns provide you with a few extra holes if you're not careful!
    
    Imps: You thought an imp was cute little dude in a red suit with a pitchfork.
    Where did these brown bastards come from? They heave balls o' fire down your
    throat and take several bullets to die. It's time to find a weapon better than
    that pistol if you're going to face more than one of these S.O.B.s.
    
    Demons: Sorta like a shaved gorilla, except with horns, a big head, lots of
    teeth, and harder to kill. Don't get too close or they'll rip your fraggin' head
    off.
    
    Spectres: Great. Just what you needed. An invisible (nearly) Demon.
    
    Lost Souls: Dumb. Tough. Flies. On fire. Flying skills with a hot temper. They
    like to go for a screaming head-on collision.
    
    Cacodemon: They float in the air, belch ball-lightning, and boast one Hell of a
    big mouth. You're toast if you get too close to these monstrosities.
    
    Barons of Hell: Tough as a dump truck and nearly as big, these goliaths are the
    worst thing on two legs since Tyrannosaurus Rex. Watch out for the green plasma
    they fling at you.
    
    Cyberdemon: When you get to the end of the second episode of DOOM, you'll know.
    Get ready to see this guy a lot more often in DOOM II.
    
    Spider Masterminds: It will make you wish you never were playing DOOM in the
    first place. Watch for it at the end of the third episode of DOOM, and numerous
    times in DOOM II.
    
    Former Commando: These guys are probably the first new enemy you will
    encounter in DOOM II. They are more disgusting looking that sergeants, and are
    also more deadly due to their chain gun.
    
    Hell Knight: Slightly easier to kill than our friend the Baron, but appear in
    larger numbers.
    
    Arachnotron: Smaller than the Spider Mastermind, and a lot harder to kill, but
    there are a lot more of these guys. Watch for its BFG9000-like green plasma.
    
    Pain Elemental: Watch out for these guys, they fly around and fire Lost Souls at
    you. If you don't kill them quick enough, the Lost Souls will eat you for lunch.
    
    Revenant: These huge skeletons are just cruel. They punch and kick the life out
    of you, and also enjoy launching flaming rockets into your torso.
    
    Mancubus: He is fat, ugly, and like shooting enormous fireballs into you from
    his arms.
    
    Arch-Vile: Not only does he summon the fire elementals to watch you go up in
    flames, he revives already dead demons while he's at it.
    
    SS Officer: This is only found in the U.S. version of Doom II. This is because
    anything that has to do with Nazis is forbidden by law in Germany, so they had
    to cut this in the German version of Doom II. They are about the size of a
    Former Human Sergeant with the blue uniform on from Wolfenstein 3D. To attack
    you, they fire a pistol at you which sounds like a shotgun. They drop a clip
    when they attack you, and it does not hurt you a lot. Use any weapon to take
    down these weak soldiers. Only found in Level 31: Wolfenstein and
    Level 32: Grosse.
    
    Commander Keen: Also found in the U.S. version of Doom II, as it is found in a
    level with SS Officers in it. Also from the Commander Keen series. They are
    little guys hanging from the ceiling at the end of Level 32: Grosse. Just one
    shot from the Super Shotgun can take out all 4 of them. Once all of them are
    dead, you can exit the level. They do not attack you as well.
    
    --------------------------------------------------------------------------------
    
    6.) Items
    ----------------------------------------
    Health/Armor
    --------------------
    
    Health Bonus or Health Potion: This adds 1% extra Health to your current health.
    With this, you can go past 100% health.
    
    Armor Bonus or Spiritual Armor: This adds 1% extra Armor to your current armor.
    With this, you can go past 100% armor.
    
    Stimpack: This adds 10% health to your current health. You cannot go past 100%
    health using these.
    
    Medikits: Better than the Stimpacks. These add 25% health to your current
    health. You cannot go past 100% health using these.
    
    Security Armor: When you pick this up, this sets your armor to 100%. This will
    not work if your armor is greater than 100%.
    
    Combat Armor: This is the blue armor. When you pick it up, it sets your armor to
    200%.
    
    Soul Sphere: This increases your health by 100%. The maximum health you can have
    is 200%, so this is a really useful item. Only use it when you are low on
    health, but grab it when you really need it.
    
    Megasphere: The best health item you can get. Once you pick it up, it sets both
    your health and armor to 200%! This is very useful, but if you are high on
    health, leave it where it is and come back to get it when you are about to exit
    the level.
    
    --------------------
    Ammo
    --------------------
    
    This is the ammo you can get throughout the game. It shows how much it gives on
    easy/hard skill levels, what weapon it is used for, etc.
    
    Use this table to find out the name of ammo used for each weapon. The "small
    ammo" is very little ammo that doesn't give you a lot. "Large Ammo" is ammo
    that comes in bigger amounts and is a lot more useful.
    
    |-------|------------|-----------------------|
    |Weapon | Small Ammo | Large Ammo            |
    |-------|------------|-----------------------|
    | P/CG  | Clip       |Box of Bullets         |
    |-------|------------|-----------------------|
    |SG/SSG |4/8 Shells  |Box of Shotgun Shells  |
    |-------|------------|-----------------------|
    | RL    |Rocket      |Box of Rockets         |
    |-------|------------|-----------------------|
    |PG/BFG |Energy Cell |Energy Cell Pack       |
    |-------|------------|-----------------------|
    
    P: Pistol
    SG: Shotgun
    SSG: Super Shotgun
    CG: Chaingun
    RL: Rocket Launcher
    PG: Plasma Gun
    BFG: BFG9000
    
    Here is the amount of ammo each type gives out.
    
    ----------
    Pistol/Chaingun Ammo
    ----------
    Clip: Gives out 20 bullets on skill 1, 10 on harder skill levels. If you pick
    it up from a Zombiemen, it will give you 10 on skill 1, 5 on harder skill
    levels.
    Box of Bullets: Gives you 100 bullets on skill 1, 50 on harder skill levels.
    
    ----------
    Shotgun/Super Shotgun Ammo
    ----------
    Shotgun Shells: Gives you 8 shells on skill 1, 4 shells on harder skill levels.
    Box of Shells: Gives you 40 shells on skill 1, 20 on harder skill levels.
    
    ----------
    Rocket Launcher Ammo
    ----------
    Rocket: Gives you 2 rockets on skill 1, 1 on harder skill levels.
    Box of Rockets: Gives you 10 rockets on skill 1, 5 on harder skill levels.
    
    ----------
    Plasma Gun/BFG Ammo
    ----------
    Energy Cell: Gives you 40 cells on skill 1, 20 on harder skill levels.
    Energy Cell Pack: Gives you 200 cells on skill 1, 100 on harder skills.
    
    --------------------
    Power-Ups
    --------------------
    
    These are items that will be a big help to you throughout the game. They help
    you or protect you of some sort.
    
    Backpack: This is probably my favorite item in the whole game. When you pick it
    up, it doubles the amount of ammo you can carry! For example, the maximum
    amount of bullets you can carry is 200. With a backpack you can carry 400. Just
    take your maximum ammo and multiply it by 2.
    
    Berserk: Man, this is a really fun item right here. When you pick it up, it
    will set your health to 100% if it is below 100%. The second effect is that
    your screen will go red and it will power up your Fist! The red screen lasts
    for a few seconds, and this will remain in effect for the rest of the level.
    During this time, your Fist will become very powerful, and it will be able to
    knock out anything weaker than a Demon in one hit. It can knock out stronger
    enemies in just a few punches! Very useful to save ammo as well.
    
    Computer Area Map: Another useful item if you may happen to get lost. Once you
    pick this up, it will fill your Automap 100% so that you can see everything on
    the Automap! Areas that are in gray are areas that you have not visited yet.
    However, this will not add object indicators to the Automap (where you can see
    items and enemies moving around).
    
    Invisibility Sphere: This red orb is something that makes you invisible. While
    you are invisible, enemy attacks will be less accurate, and when they try to
    attack you, it may miss. But you won't be completely invisible, as enemies just
    have more difficulty spotting you. The other part is that this is on a time
    limit, and you will be invisible for a minute.
    
    Invincibility Sphere: Just the exact thing you'll need when you are in a
    hellhole. While you are invincible, your screen will go white. This effect
    lasts for 30 seconds. Also when you are invincible, you cannot be damaged in
    any way. This includes enemy attacks, crushing ceilings, and even slime pits.
    It just lasts for 30 seconds, and the white screen can be annoying.
    
    Radiation Suit: Something you will really need in levels with a lot of slime
    pits. When you pick one of these up, your screen will go green for a minute.
    During this time, you will not be hurt when you are walking around in slime, as
    this gives you protection from lava and slime. This effect lasts for a minute
    and you can still get hurt by enemies, even if you do have this on.
    
    Light Amplification Visors: A really, really, neat power-up. When picked up,
    the brightness greatly increases for 2 minutes, and then the screen will return
    back to it's normal brightness. These goggles are useful for getting pack dark
    areas/mazes. Yeah, this means every area in the level will be 100% bright as
    long as you have these on.
    
    --------------------
    Key Items
    --------------------
    Keycard/Skull Keys: Found in levels, these keys come in 3 colors: red,
    yellow, and blue. Not all keys are in all levels, so keep that in mind. These
    keys open a locked door, activate certain switches, etc.....
    
    Also, many of the doors are not 100% blue, red, or yellow. If the door has red,
    yellow, or blue lights to the sides of it, that's also a red, yellow, or blue
    door. There may be a level with a Yellow and Red Key, but you may not need the
    Yellow Key to complete that level (that sentence right there is made up, just
    giving you a little example of that some keys in a level might not be needed to
    finish that level).
    
    --------------------------------------------------------------------------------
    
    7.) What to Look out For
    ----------------------------------------
    What I mean is that watch out for these things. They can hurt you, depending on
    what you do. Some can be useful, so will not.
    
    Barrels: These can be your best friend, or your worst enemies. These are
    scattered around many levels, and can help you a lot. To make very good use of
    these, lure a lot of enemies to one barrel, and shoot the barrel. It should
    explode, and hurt/kill the enemies near it. Or if you shoot the barrel when
    you're right next to it, you'll be hurt/killed. Even enemies can blow up
    barrels, so you can use them to blow them up and save your ammo.
    
    Crushing Ceilings: Crushing Ceilings can appear at a nasty time, so watch out.
    Just like Barrels, these can be your best friend or worst enemy. These ceilings
    fall from the ceiling and touch the ground, and rise back to ceiling, and so
    on. You'll need to time your moves right to get past these. Also, their good
    use is that Crushing Ceilings can also crush and kill enemies, saving your
    ammo. But they can crush you too, and these do hurt.
    
    Slime/Lava/Blood: These appear on floors. Slime is green, lava is a mix of red
    and yellow, and blood is red. Whenever you step on these kinds of floors, there
    is a good chance your health will decrease each second. The amount of health
    decreased depends on your armor and what kind of toxic floor you stepped into.
    All types of toxic floors cannot hurt enemies, sadly. You will not be hurt from
    these floors if you step on them while having an active Radiation Suit on.
    
    --------------------------------------------------------------------------------
    
    8.) The Ultimate Doom Walkthrough
    ----------------------------------------
    Now, here's the walkthrough (note that this walkthrough is not useful for skill
    level 5)! Also some enemies I tell you to kill in this game may not be there
    because of the skill level so if you don't see an enemy I told you to kill in
    this guide, then you're playing a low skill level.
    
    <><><><><><><><><><><><><><><><><><>
    Episode 1: Knee Deep in the Dead
    
    <><><><><><><><><><><><><><><><><><>
    
    -------------
    E1M1: Hanger
    -------------
    
    At the start, there is a health potion to the left and right of you. Go straight
    and enter the room to the left, and beware the Former Human Sergeants on skill
    levels 4 and 5. Take their Shotguns, including the Combat Armor, health potions
    and spiritual armor. When you are done, leave the room, and head left into the
    opening, and go through the door. Before you do that, don't forget about the
    spiritual armor against the wall.
    
    Kill all the enemies in this room, and watch out for the Former Human Sergeants
    on skill levels 4 and 5. When this room is empty, collect all the items and ammo
    here, and go through the opening at the east part of the room.
    
    Kill the Former Human at the stairs, and collect the health bonuses, and go down
    the stairs. Kill every enemy here, including the Imp(s) on the platform. Get
    past the zigzag floor to the other side of the room. Before you open the door,
    check the walls to the right until you find a secret area. In here, go down the
    stairs and kill the Former Human Sergeants on skill levels 4 and 5, and collect
    the ammo and health here. Go outside and collect the Mega Armor, and go back to
    the zig zag room, and now go through the door.
    
    Kill the enemies here, and get the health, and go to the exit door. But before
    you go into the exit room, go back to the zig zag room (again). Remember that
    platform that had the Imp(s) on it? It's now been lowered. Go into the new room
    that was behind the platform, and get yourself a Shotgun on skill levels 3 and
    below, with a box of shells and health, and a Former Human Sergeant on skill
    levels 4 and 5. Now go back to the exit door, open it, grab the items, and hit
    the exit switch.
    
    --------------------
    E1M2: Nuclear Plant
    --------------------
    
    Get out of the starting alcove and go right. You will be in front of a door,
    but go left, and kill any Former Humans there. Now check the wall across from
    the wall in between the 2 doors until the wall opens. Grab the goodies in here,
    and flip the switch (don't forget the backpack), and leave this room. Take the
    door to the left, and kill the Former Humans in front of you.
    
    Go up the stairs, and while you're climbing up, go through the opening to the
    left when you see it. On skill levels 4 and 5, beware of all the nasty Shotgun
    Guys here. But out here you can get a Soul Sphere and a Chaingun and some
    Chaingun ammo. Now go back through the opening. Climb up the stairs in front of
    you, and when you get to the top, skill the enemies here, and get the Red Key
    in this little room. Now go back to the room we started in.
    
    Get to the other side of the room, killing any Former Humans in your way. Go
    through the Red Door. Kill all the enemies in front of you, and head straight,
    going up the stairs. From the edge of the stairs, get to the other side of the
    room, and collect the health and ammo, and go down the elevator.
    
    Down here is an "ambush" of Imps and Former Humans. Kill all of them, even the
    Imps on the high platforms. Hit the switch, and 2 doors will open. Take either
    one, and go right down the stairs, and open the exit door. Kill the enemies, go
    down the lift, and watch out for that nasty Imp there on hard skill levels, and
    hit the exit switch.
    
    ---------------------
    E1M3: Toxin Refinery
    ---------------------
    
    Open the door in front of you. Kill all the Former Human Sergeants, Former
    Humans, Demons, and Spectres (on high skills) in here, and go left, following
    the hallway into a door. When you open it, shoot the barrel to see those 2
    Former Humans go to waste. Go right up the stairs, and take a left, going down
    some stairs. Down here, kill the Former Human Sergeants and Imps to your left.
    When they are all dead, go left where they were and hit the switch.
    
    Go back upstairs and to the right. A new passage in this room has opened. Go up
    the stairs, killing any enemies in your way. Leave the room once you do (down
    the stairs), and go back up. As you are getting up the stairs, you should hear
    the sound of an elevator. Here's a little map where the sounds are coming from:

                              | X   |
    Say the X is you. The sounds are coming from A1, and A2, which are the
    platforms in front of the "computer wall". Run to A2 first (get on the platform
    that dropped, and walk to the "computer wall" and it should open. Go
    downstairs, and kill any Imps there. Hit the switch on the pillar and get the
    Soul Sphere when it comes down. Go back, exit A2, and run to A1, and do the same
    thing as last time (kill the Imps, Demons, and Former Human Sergeants in your
    way). When it does open go straight, kill any Former Human Sergeants or Imps
    here, and get the Rocket Launcher and Armor. Go right, jumping in the toxic
    river, entering the slime tunnel.
    
    When you get to the end, hit the switch, get the backpack, and check the walls
    to the right of the switch until the door opens. Go inside, get all the goodies
    in here, hop on the elevator, and check the wall at the end of the room, and it
    should open. Grab the stuff in this room, and take the lift down, and go back
    up the stairs from this familiar room. Go right again, open the door, and cross
    the new bridge made. When you get to the wall, it should open.
    
    Walk up and kill the Imp in front of you, and walk straight, and the wall
    should open, revealing Former Humans and Former Human Sergeants. Kill them all,
    walk straight
    and another wall should open, revealing Imps. Kill all of them, and go into the
    room they came out of. In here, go through the opening, and follow it to the
    exit door. Open it. In here, check the wall to your left, and it should lower
    like a lift. Get on it, and ride it to the top. Kill the Imp up here, and get
    the Box of Rockets.
    
    Now turn back around and drop down to the exit room. Down here again, hit the
    exit switch (this takes you to the secret level).
    
    --------------------
    E1M9: Military Base
    --------------------
    
    At the start, collect the two clips to the left and right of you, and get out
    of the alcove. Kill all the Imps in the Imp Cage, and kill any
    Former Humans/Former Human Sergeants that come for you. Take the staircase to
    the left of the
    starting alcove, go down, and kill all the enemies down here. Walk around the
    cage to get the Yellow Key.
    
    Now go back upstairs and take the staircase to the east and go down. When you
    get to the bottom, go left, down the stairs to the Yellow Door. Kill all of the
    Former Humans, Former Human Sergeants, and Imps in front of you, and get the Red
    Key in this
    room. Watch out for the opening wall revealing Former Human Sergeants too.
    
    Exit the Yellow Door we came from, and get to the other side of the room to the
    Red Door. Open it, and kill all the Former Humans, Former Human Sergeants, and
    Imps, and then
    go to the other side of the room and enter the little alcove. Destroy the
    barrels (stay at a safe distance), and hit the switch.
    
    Go back out the Red Door we came from, and a little Demon Pen has been
    released. Get the Demons out of the way, and collect the Blue Key from the
    Demon Pen. Go upstairs from this room, and take the staircase across from us.
    
    Open the Blue Door, and kill any Former Humans, Former Human Sergeants, Imps,
    and Spectres in this room. When you're done, jump into the slime pit, and take
    either way to this switch. Activate it, and go right from the switch, and this
    door should open. Go through it, kill all the Imps, and take the lift up. There
    may be another Imp there, so watch out, collect the health. Check the wall in
    front of you, and it should open. Go across the new bridge, get the health in
    front of you, and exit the level.
    
    ----------------------
    E1M4: Command Control
    ----------------------
    
    At the start, go to the door, but check the wall to the left and it should
    open. Take the backpack, health, and Shotgun Shells, and go back out to open
    the door.
    
    Kill the Former Humans to the left, and take the middle opening in this room.
    Kill the Former Humans in here, and hit the switch and a lift should lower. Take
    it up and go right, and walk up to the doors in this room. They should open by
    themselves. Go in, kill the Imps, grab the health bonuses and Chaingun, and
    pick up the Blue Key. If you are locked it, stand on the light the blue key
    was on, the doors will open. Get out of this room.
    
    There are 4 ways out of this room. Look for the entrance that has white lights
    to the left and right of the opening. When you do, go in and go left. Kill the
    Former Human Sergeants here, and enter the Blue Door.
    
    Watch out for Imps and Demons in this maze (try to kill them if they get in
    your way). To get out, go right until you hit a wall, and go right again into
    this little small room. Take a left, and go left again, and you're out of this
    maze. Turn right to get some health, armor, and the Yellow Key. Go up the
    stairs in this room, and hit the switch next to the Yellow Door. Open the
    Yellow Door, go right, go left, and then left again up the stairs, and cross
    the bridge to the exit door. Open it, and hit the exit switch.
    
    -----------------
    E1M5: Phobos Lab
    -----------------
    
    Go across the slime pit, and in this room, go all the way right (there is a
    door, but skip it) , and at the end, turn left into a "balcony", and a platform
    across from us should rise. Leave the room, kill any enemies in your way, going
    straight. Keep going until you find a staircase to your right, and then climb
    it. Destroy the 2 barrels and check the wall they were in front of. In this
    secret room, grab the Shotgun, the ammo, and the health and armor bonuses. Get
    out and go right onto the new bridge, and follow it to an opening. Kill the
    enemies, and go forward to get the health and Yellow Key. Leave this room and
    jump into the slime pit, go straight, check the brown wall, and it should open.
    Collect the armor, Rocket Launcher, and ammo, and go into the opening. Go
    straight, collecting health and ammo, but when you try to pick up the small
    Shotgun Shells in front of the wall, the wall should open, and get out of this
    secret room.
    
    Back in this familiar room, kill any appearing enemies coming from the door.
    Now open the door. Kill all enemies here, and when you're done, open the Yellow
    Door. Take the lift down, and kill any enemies there. Go either left or right,
    there's no difference, but watch out for the doors that open, containing
    enemies. When you've reached the other half of the room, jump in the acid, run
    across it, and hit the switch, and then two pillars with enemies will lower.
    Kill them, and get back to (and open) the Yellow Door.
    
    Run across to the new opening, killing the enemies in your way. At the top of
    the stairs, turn left and kill the enemies, and grab the health if necessary.
    Go up another set of stairs killing all of the enemies. In this room is a
    switch (which is a door), but before you open the door, check the walls to the
    right of the door until you find a secret area. In this secret area, there's a
    Chaingun, health, Backpack, and a Computer Area Map. Now go to the door.
    
    Watch out in this semi-dark hall. Follow it, killing the enemies, and at the
    end of the hall is another room. Kill the enemies, grab anything you need,
    including the Blue Key. Hit the switch, turn around, go down the stairs, kill
    any Spectres that should be there, and enter the Blue Door.
    
    Be careful in this dark room....actually you don't need to! There are some
    Light Amplification Visors in here, and I'll show you where they are:
    
                             |----------|        |        |
     |      |                |          |        |        |
     |      |                |          |        |        |
     |      |----------------|          |--------|        |
     |                                                    |
     |-----------------| |------| X |---------------------|
     | A                 |      |---|
     |-------------------|
    
    So say you're the X, and the Visors are "A". At the start of the Blue Door,
    turn left, and looking to the left, look for an alcove. This is an easy to miss
    alcove, so watch out. So turn left when you see it, and follow the passage to
    the Visors, along with so other goodies. This does count as a secret too.
    
    When you are done with that, get to the northern half of the room, killing all
    enemies in your way, and open the exit door. Kill the Demons there on skill
    levels 4 and 5, and then hit the exit switch.
    
    -------------------------
    E1M6: Central Processing
    -------------------------
    
    Go straight down the hallway at the start, and when you get to the first 4 way
    intersection, go right, and kill the enemies in your way. Enter the room,
    destroy all the barrels (always stay at a safe distance), and look around this
    room for the Red Key. Once you pick it up, you will be locked up in this room
    and be ambushed by a bunch of monsters for a certain amount of time. While
    waiting for the doors to open, kill the enemies, grabbing ammo and health while
    you're at it.
    
    Once the door opens, Go all the way straight to the red doors (watch out for
    any remaining enemies), and open either one. Follow the hall from the door you
    took to a larger opening, and go through to get the Blue Key. Instead of going
    back to the Red Door, jump into the slime pit and go left, and get on the
    ledge, and grab health and other neat things. On the same ledge, go into the
    alcove, follow it to the stairs, go up them, and grab everything in here. Hit
    the switch (it is a door), and forward to the 4 way path. Go straight, opening
    the door.
    
    Turn right, follow this hall to another room to the right, and go into the
    room. Get to the Blue Door. Touch it, but don't open it. Look behind you to the
    left: a platform with enemies behind it is lowering. Kill all the enemies
    behind the lowered platform, and go in the small dark room behind the lowered
    platform. Check the wall in between the Medikit and Radiation Suit, and you
    should find a secret area, which has a Backpack, Rocket Launcher, and an
    Invisibility Sphere. Open the Blue Door here (it's a wall, actually), and kill
    the Imps here, and get the Yellow Key (this was a QUICK shortcut to the Yellow
    Key) and another Backpack. Follow down the hall until you here an opening, and
    run back to the Blue Door (you won't see the lights this time, but it's still
    here), open it, grab the Radiation Suit (if you haven't yet), and go straight,
    into the alcove in the slime pit, killing the Imps. Follow this alcove to a
    door and some goodies. Open the door.
    
    On Skill levels 4 and 5, there will be a whole bunch of Former Human Sergeants
    here. Kill them all, jump down there, and take their Shotguns. Also, check the
    platform the Soul Sphere is on. It will lower, and grab it. Stay on the
    platform, and when you get as high as it goes, check the green wall and it
    should open. Get into the room killing any enemies, and then go straight, and
    then go right, going up the stairs. Kill the Imps up here, and hit the switch.
    Go back downstairs, turn right, and go into the slime pit into the door. Kill
    the enemies at the door. In this room, there are 3 staircases. Take either the
    left or the right one, and follow the halls into another room.
    
    In this big room, kill all the enemies in here. Then go into the small alcove
    and hit the switch. Behind you is a big ambush of enemies. You can kill them,
    or try to avoid them and run into the alcove in the northeast part of the room.
    Open the exit door, collect the health here, and hit the exit switch.
    
    -----------------------
    E1M7: Computer Station
    -----------------------
    
    At the start, collect the ammo here, and open the door. Kill all the enemies in
    your way, and from the door, go left, and follow the hall to a bigger room. Go
    into the alcove, and take the lift up. Kill all enemies in your way, and follow
    this ledge into a dark room. Grab the health, kill the enemies here, and take
    the Yellow Key. Get back out, jump off the ledge, and go straight (not up the
    stairs) to the Yellow Door.
    
    Open the Yellow door, killing any enemies in your way, going straight. At the
    end, go left, and go all the way straight, and at the stairs, destroy the
    barrels, and kill the Former Humans there. Go up the small set of stairs, and
    kill the Former Human Sergeants from the pillar that lowers. There are two
    passages to take: take the one on the right, and kill the enemies in your way.
    Go straight until you get to the door, and open it.
    
    Kill any enemies that are there, and get the Northwest part of the room, and
    take the lift. Grab the health if you need to, and when the lift reaches the
    top, follow this hallway to the Red Key, killing enemies. Once you get the Red
    Key, backtrack your steps to the lift, and take it down. In this room, avoid
    the new enemies, running to the door. Run straight out of this room too, and
    get past the pillar down the stairs, keep going straight, and get back to the
    Yellow Door.
    
    Open it, go left, and take another left up the stairs. Go straight to the other
    set of stairs, and descend them. At the bottom, go right all the way, then turn
    left to the Red Door. Open it, kill the Imps if you haven't and go straight to
    get the health and the Blue Key. Leave this room. Go all the way right to the
    Yellow Door, skipping the new alcove. Go right until you see the Blue Door, and
    open it.
    
    Kill the enemies in your way, and go up the stairs. In this room, go straight,
    into another room. Follow its hallway to another room, killing the enemies in
    your way. In this dark room, hit the switch, and leave this room, going into
    the room near the Blue Door. On the other side of this room, a door has been
    opened. Go into the new room, kill any enemies in your way, go through the exit
    door, and hit the exit switch.
    
    ---------------------
    E1M8: Phobos Anomaly
    ---------------------
    
    You've made it to the final level of episode 1! Anyway, hit the switch at the
    start, and the wall will lower. From where you are, shoot a barrel and watch
    many of the Demons die. Kill the leftover ones, and get off the platform you're
    on, and turn left down the stairs. While going down the stairs, check the walls
    to your right, and you should find a hidden Soul Sphere. Now, enter the door at
    the bottom.
    
    If you need ammo, there is some Shotgun and Chaingun ammo in the rooms to the
    left and right, but watch out for the Demons there on hard skill levels. Now
    get out of the room you are in, and get to the other end of the room (from the
    door). Hit the switch, and take the lift.
    
    Walk up forward, and 2 doors will open, both will have 1 Baron of Hell. Here
    are some tips for beating them:
    
    1. If you have plenty of Rocket Ammo, use it on them, no matter how many
    rockets you have.
    2. Watch out for the Spectres on skill levels 4 and 5. Get them out of your
    way.
    3. Run around the room, taking potshots now and then.
    4. If you find you are low on ammo, you can lure them to the barrels, and at
    least damage/kill one.
    5. On skill levels 4 and 5, you can have the Spectres get in a fight with a
    Baron to weaken him (the Spectre needs to be hit by one first though).
    6. The Barons will respawn on skill level 5, so finish them off quickly.
    
    Once you've defeated both Barons, the walls will lower. Jump down to the lower
    ground, and down there is a "building". Hit the switch on it, and the stairs
    will rise. At the top, take the teleporter, let the enemies kill you inside,
    and you've beat episode 1!
    
    Once you die (you have to), you get a little story:
    ------------------------------------------------------------
    Once you beat the big bad-asses and clean out the moon base you're supposed to
    win, aren't you? Aren't you? Where's your fat reward and ticket home? What the
    hell is this? It's not supposed to end this way! It stinks like rotten meat,
    but looks like the lost Deimos base. You're stuck on the Shores of Hell. The
    only way out is through. To continue the Doom experience, play the Shores of
    Hell, and its amazing sequel, Inferno!
    ------------------------------------------------------------
    
    A few seconds after the story is over, you'll see a screen of the id software
    employees, who make this game, and what they did (level design, music, etc).
    After that, press escape, select New Game, then pick the Shores of Hell. Select
    your skill level, and you begin Episode 2.

    ---------------------
    E2M1: Deimos Anomaly
    ---------------------
    
    You start out in an alcove. Get out and go right, skipping he teleporter (but
    grab the Shotgun that's there on skill levels 1 and 2 next to it though). Kill
    the Former Humans in your way, and pass the evil red cross, going right. Kill
    the Former Humans here that appear on skill levels 3 and above, and grab the
    Medikit and Blue Key here. Go through the teleporter we skipped.
    
    Kill any enemies in your way, and head straight, on skill levels 3 and above,
    grab the Shotgun on one of the red triangles, Continue through more of the
    room, killing any enemies in your way. Cross the red blood pit, and hit the
    switch on the right wall. A little lump with a switch on each side behind you
    will rise. Hit the switch on both sides, and go through the last teleporter we
    visited. From here, go past the red cross again go right, and go through the
    new teleporter here. In this room, kill all enemies (watch out for the
    Cacodemon on skill levels 3 and above), and once the room is cleared, grab the
    Plasma Gun and Cell Pack here. Leave this room, go through the teleporter near
    the start, and go across the blood pit (don't go to the teleporter yet).
    
    To the left of the teleporter is a small opening. Enter it, and in this small
    hallway, collect the health and Red Key. Exit this secret room, and now go
    through the teleporter. In this room, go through the small alcove in the left
    wall, and flip the left switch. Where the switch we flipped is, a secret area
    will appear (this only happens once), and enter the teleporter in the secret
    room.
    
    Rush through this secret hallway, collecting the armor and health bonuses, and
    go through the teleporter at the end of the hall. If the secret door closed,
    hit the switch to open it. Now hit the other switch we didn't flip yet. Leave
    this small alcove, to find that a platform is lowering. When it does lower,
    kill the enemies there, and when it is clean, go straight, and enter the Red
    Door. Kill the enemies inside, and grab all the goodies here, and leave this
    room, going straight to the Blue Door. Open it, and take the teleporter.
    
    Kill the enemies in here, and grab the health in here. Hit the switch in this
    room, and the stairs will raise in the alcove. Kill the Lost Soul/Cacodemon
    there (skill level varies), climb the stairs, hit the switch, and exit this
    alcove. Go through the new teleporter that lowered, and enter it.
    
    Walk forward, and the wall in front of you will lower. Watch out for the
    Cacodemon on skill levels 4 and 5. Kill it, or avoid it, open the exit door,
    kill the Imp there, and hit the exit switch.
    
    -----------------------
    E2M2: Containment Area
    -----------------------
    
    Grab the armor in the right alcove if you need to. Go straight, killing the
    Imp, and then flip the switch on the left wall. Turn around, and find that the
    crate containing the Shotgun/Ammo (it's ammo on skill levels 1 and 2, and a
    Shotgun on skills 3 and above, but the Shotgun on skills 1 and 2 is in the
    alcove behind the crate with the Ammo) has lowered. Take whatever is there, turn
    around, go straight, and when you have the choice to go left or right, go left.
    Go straight to the Berserk pack across from us, and go right, killing any Imps
    in your way. Enter the non-crate room.
    
    You can easily outrun these Imps in here. Get to the other side of the room,
    and just before the door is an alcove with a switch on the left wall. Flip it,
    and the door we were just at has opened. Go through it, and go forward inside,
    and stairs to the platform will rise. At the top, go straight, to the other end
    of the room. Again, when you have the chance to go left or right, go right. Go
    all the way straight and when you see the exit door, don't jump into the slime
    pool in front of it. Kill any enemies in your way. When you see the exit door,
    you can't access it, you'll need to hit a certain switch first. From our view
    of the exit door, go left, go left again past the Red Door, to the crushing
    ceiling hallway. Oh no!
    
    There may be enemies in front of us, but let them commit suicide under the
    crushing ceilings. Timing your moves right, get to the other end of the
    crushing ceiling hall. Now, follow this hallway to a slime pool. Cross it to
    get the Blue Key. From the Blue Key, there's an alcove to the right wall. Climb
    down the stairs, and open the Blue Door, and kill the Spectre there on hard
    skill levels. Go through the Blue Door, and go right, and open this Blue Door.
    Walk forward to get the Red Key. Leave this room, go back through the other
    Blue Door, and backtrack your steps to the Red Door.
    
    Open the Red Door, turn right, take another right, and flip the switch. Watch
    out for the Imps though. Leave the Red Door. Now, a bridge is rising to the
    exit door. Cross it, open the exit door, and hit the exit switch.
    
    ---------------
    E2M3: Refinery
    ---------------
    
    There's a door to the right, but skip it, and go straight. At the Cacodemon
    cage, turn left, and then right. Go through the opening, turn left, and kill
    any Former Humans there. From the Blue Door, go right, and go straight until you
    hit a wall. Turn right, go straight, take another right, and kill the Imps and
    Demons there, and go straight. Before taking a turn into the pillar room, check
    the green walls across from it. Use this map to nail it down:
    
           |                     |    |-------------------|

    Once you do find the secret, walk in, turn right, cross the slime pit and pick
    up the Backpack. Exit this secret room, and no go into a pillar room. Instead
    of crossing all those rising and dropping pillars, check the walls to the left
    when the entrance of the room. A wall should rise, go into this room, and kill
    the enemies in here. From where we entered into this room, go right, and pick
    up the Shotgun on the platform. No go straight (not to the slime pool), turn
    left, and take a right into a room. Now go straight, jump into a blood pit, and
    go right onto a platform. Kill any Lost Souls here, and grab the Plasma Gun and
    its ammo. Jump off the Platform (not into the Blood Pit), and kill the Demons
    here. In this room, behind the pillar is the Blue Key. Leave this room, but
    watch out for the Baron on skills 4 and 5. Once you leave the room, turn right,
    and at the end of the room, turn left, and go straight, into the big room
    across from us. At the end of the room, search the wall that's in between 2
    gray skinny poles (the one on the right), and the wall should open.
    
    Go into this room, go straight, and when you reach the wall, go left to the
    Blue Door. Open it, kill any enemies in your way, and go right, through a dark
    hall. Follow it to a bigger room, kill any enemies in your way, and collect all
    of the goodies in the bigger room. In the northwest part of the room, enter
    into a dark room. I'll show you the quickest way to get out of here: From the
    start of this pillar room, go all the way right until you hit a wall. Then, go
    left until you hit another wall. Go right until you hit another wall. Then go
    left, and to the right is the exit out of this room. Cross the slime pit, turn
    left, and then go right into another room. Kill any enemies here, enter the
    exit door, and hit the exit switch.
    
    -----------------
    E2M4: Deimos Lab
    -----------------
    
    At the start, check the flashing wall to the right, and it should open. Go into
    this secret area, and collect all of the goodies in here. Leave this room, go
    right, and go through the teleporter. In this room, go through the opening in
    the left, and rush to the opposite wall. Go right, left, and then straight,
    skipping the opening to the right. Now go left, kill the Imps here, and open
    the door. The enemy in front of you varies: Demon on skills 1 and 2, a Baron on
    harder ones. Avoid or kill the enemy, and at the left side of the room, flip
    the switch, and take the lift to the left of it. Ride it to the Blue Key. Jump
    off the platform, and exit this room.
    
    Go straight, and then right. Now go left into the opening we skipped. From
    here, run to the Blue Door Across from it. Enter it. Follow this hallway to the
    Yellow Door, but since we don't have the Yellow Key, go left. Run under the
    crushing ceiling to get the Yellow Key. Return to the Yellow Door, and open it.
    
    From the Yellow Door, go left, passing the staircase. After the staircase, hug
    the left wall (still move, don't stay in 1 place) until you drop into a small
    pit. In this small pit, check the walls until an opening is revealed. Get the
    Plasma Gun in this secret room, and take the teleporter. If you're playing on
    skill levels 3 and above, use your Plasma Gun to kill the Cacodemon in front of
    you. After that, kill the other enemies, and go through the alcove in the
    northwest part of the room. Keep going straight until you get to a
    bigger room, and once you get to the bigger room, run to the teleporter across
    from you.
    
    Once you've entered the teleporter, go right, kill the Demon, and jump into the
    blood pit, and go left, onto a platform (DON'T ENTER THE TELEPORTER YET!), and
    hit the switch near the teleporter (there's only one). Now enter the
    teleporter. When you get back to this room, go forward, but go back into the
    teleporter. Go right again, onto the new bridge to the exit door, Open it, kill
    the Imps, but don't hit the exit switch yet. Turn around, cross the new bridge
    leading to the Soul Sphere, and grab it. Now go back to the exit door, open it,
    and hit the exit switch.
    
    ---------------------
    E2M5: Command Center
    ---------------------
    
    At the start, open the door, and kill the enemies. Take the staircase at the
    southeast part of the room, and climb it. At the northeast part of the room,
    hit the switch (it's a door), and go through into this room. Follow the hallway
    to a switch (another door), open it, and go through it. In this room, open the
    door to the right, and kill the Demons inside. Go into the room, and hit the
    switch in the small alcove. Leave this room, and turn right. At the wall, turn
    another right, to see that the stairs have appeared. Climb them, go through the
    red wall (just walk through), and take the teleporter.
    
    Watch out for the Lost Souls in this room. Kill them if you can, and try to
    open the door in this room (it's a switch). When it opens, get to the exit door
    on the other end of the room, and hit the exit switch (this exit leads to the
    secret level ;)).
    
    --------------------------
    E2M9: Fortress of Mystery
    --------------------------
    
    Run straight to the wall at the beginning and pick up the Plasma Rifle (equip
    it too). Turn around and blast down the 4 Barons. When they're all dead, grab
    the goodie from each alcove (there's a Shotgun, Chaingun, Rocket Launcher, the
    Plasma Gun we got, Chainsaw, Backpack, and Computer Area Map, grab everything).
    Open the door in one of the alcoves, and go into the room.
    
    Use your Rocket Launcher and Plasma Gun to kill all the Cacodemons in here, and
    when the room is empty, collect the health and ammo, then the Soul Sphere. From
    the door we entered, check the wall across from it (the wall in the room with
    all the Cacodemons), and it should open. In this room, flip the switch to the
    left and the door to the right of it will open. Enter it and get the Blue Key.
    Exit it, open the Blue Door and get the Red Key. Exit that room, and enter the
    Red Door to get the Yellow Key. Open the Yellow Door and go through the exit
    teleporter.
    
    Tip: If you don't have enough ammo, lure the Barons of Hell and Cacodemons into
    one room, and have them fight off each other. You can then kill the remaining
    enemies easily.
    
    --------------------------
    E2M6: Halls of the Damned
    --------------------------
    
    Go into the other room at the start. Kill any enemies here, and grab the Rocket
    Launcher. Open the door in here. Kill the enemy in front of you (if one is
    there), and hit the switch. Leave this room, and go back into the room we
    started in. Go past the new opening and go right. Go all the way straight, past
    all of the pillars, and hit the switch when you get to it. A platform to the
    right of it will rise, and use that platform to get to that Berserk Pack. Take
    it, and see that the platform around the pillars have lowered to just a slime
    pit. Get off the platform you're on, and RUN through the new opening in the
    western part of this room. Follow it to a switch and some health. Once you hit
    the switch, get out of this room, go left onto a platform, collect the health,
    and go left into a new opening, where there's a Blue Door, and to the right is
    a normal door. Go through the normal door, having a Shotgun or Chaingun ready.
    
    Go all the way straight, killing any Former Humans/Former Human Sergeants in
    your way. When you have the choice to go left or right, go left. Go straight,
    and go left to get the Blue Key. Turn around, go right, then all the way
    straight (skip the hallway to the left as we progress), until you get to a brown
    opening. Go inside this dark, brown room (this is a maze if you were wondering).
    I don't know the exact guide to the door in here, but all I can tell is look
    around until you find a door in here, and kill any enemies in your way. Once you
    find the door, go through it, and go right, going through a hallway. When you
    get out of this hallway, go left, and take another left to a small room, and in
    here, and go left, and get the Red Key. Exit this small room, and backtrack
    your steps to the door, killing any enemies in your way. Go back through the
    door, and work your way out of this maze. When you do get out of this dark maze
    (to the bright white halls again), go left, and on this part of the hall are 3
    doors to the left. Each door is separated by a wall. Take the second one.
    
    Use a Shotgun or Chaingun to blast the Former Humans/Former Human Sergeants in
    front of you. Follow this hallway to another door. Open it, go into this small
    room, and hit the switch on the right wall. A new passage behind you has opened.
    Go through it. Follow the long hallway to another room. On hard skill levels
    there will be a Cacodemon in this room. Kill it, and open the door that has a
    health bonus in front of it.
    
    In here, take either path to the other end of the room, and at the other end of
    the room is the Yellow Key. Take it, exit this room, and back in this room,
    Imps have been released. Take a left, through this same long hall again,
    outrunning these enemies. When you wind of in front of the switch you hit, take
    the door on your right, follow the hall to the other door, open it, and turn
    right. Now, kill any new appearing Demons or Barons (on hard skill levels) in
    your way. Go left past the opening to the maze, keep going straight, and then
    as you go keep on heading straight, take a left to another hallway. Run
    straight to the door, open it. To the right, open the Blue Door. Go inside and
    open the Red Door. Go inside and open the Yellow Door. Go inside and hit the
    exit switch.
    
    --------------------
    E2M7: Spawning Vats
    --------------------
    
    At the start, you'll see two openings to go through. Take the one on the left.
    Follow this hallway into another room. When you do get into the a new room, go
    straight into another room, skipping the door on your right. In this room, kill
    the Imps in here, and go right, heading down the stairs. In this large room,
    kill all the Demons in here. Grab the goodies. In the southeast part of the
    room, there is a lump with a switch on it. Hit it, and the lump will lower. Go
    through the hall into a bigger room. Kill the Cacodemon(s) and a Baron in here
    (that only appears on hard skill levels). In this room, take the health, and
    get the Blue Key. Now backtrack your steps back to the room we started this
    level in.
    
    In the room we started in, take the other opening we didn't go through. Follow
    the hall into another room. In this room, open the Blue Door. Kill the Demon in
    front of you, and go right and get the Chaingun. Now turn around, go straight
    (not up the stairs), and go through the opening to the left of the staircase.
    Kill any enemies here, and go up the stairs in the room. Follow the staircase
    to a platform with the Yellow Key.
    
    From where you are, kill the Imps in front of you. When you do, hop off the
    platform and go through the opening north of the platform you just jumped off.
    In this room, go left, and open the Yellow Door to your right. Go into the room
    killing any Imps. From the Yellow Door, get all the way to the other end of the
    room, and open the door to the right. Kill the Imps in here, and enter the
    alcove near the pillar. Follow the small hall to a switch, and hit it (kill the
    Imp in here too). Now, exit this hallway to see the pillar has lowered. Get the
    Red Key on it. Now leave this room and go left, out the Yellow Door. Out here,
    go left, and then when you get to the "rectangular" hallway, go left, and when
    you get to the wall, go right, and open the door. In this room, open the Red
    Door to your right. Go inside, and hit the switch on the right. The switch will
    disappear, and hit the new one. Leave the Red Door, kill the Cacodemon, and
    take the bridge rising to the exit door. Open it, and hit the exit switch.
    
    ---------------------
    E2M8: Tower of Babel
    ---------------------
    
    Congratulations, you've made it to the final level of episode 2! Anyway, at the
    start, turn around, and hit all 4 switches on this pillar. Walk up to 1 of the
    sets of the rising stairs, and walk up to the wall the staircase leads to. It
    will open, and go inside and grab the goodies. Take out your Rocket Launcher,
    then go outside and KILL THE CYBERDEMON! Also, his exact location is the
    northwest part of the map. Here are some hints:
    
    1. When facing the Cyberdemon, Strafe to avoid his Rockets.
    2. Watch out for the Lost Souls on skill levels 3 and above. You could try
    luring them in a fight with the Cyberdemon.
    3. If you need health or ammo, go into the other power-up rooms, then go back
    out to kill the Cyberdemon.
    4. Use the Rocket Launcher. It's your best hope.
    5. At each corner of the map there is a pillar bigger than all the others that
    is right next to the wall (they don't touch the walls, so there is a small
    crack between the pillar and the wall). If you are on one side of the crack and
    the Cyberdemon is on the other, you can shoot through the cracks with your
    Chaingun or Shotgun, and his Rockets won't pass. This takes a while, and do not
    touch the crack when the Cyberdemon fires his rockets, or you'll get damaged.
    6. Pillars are scattered all around the map. You can hide behind one when the
    Cyberdemon fires.
    7. There are also 4 power-up rooms, and each contain Boxes of Rockets, 2 of
    them have Soul Spheres, and 1 other one has a Rocket Launcher. Use them when you
    need to.
    
    Once you defeat the Cyberdemon, congratulations!
    
    Then, you get a little story:
    ------------------------------------------------------------
    You've done it! The hideous Cyberdemon lord that ruled the lost Deimos base has
    been slain and you are triumphant! But... where are you now? You clamber to the
    edge of the moon base to see the awful truth. Deimos floats above Hell itself!
    You've never heard of anyone escaping from Hell, but you'll make the bastards
    sorry they ever heard of you! Quickly, you rappel down to the surface of Hell.
    Now, it's on to the final chapter of Doom! - Inferno.
    ------------------------------------------------------------
    A few seconds after the story is finished, you'll see a screen of what the moon
    base looked like. Press Escape, select New Game. Now pick Inferno, select any
    skill level, and you start Episode 3.
    
    
    
    <><><><><><><><><><><>
    Episode 3: Inferno
    <><><><><><><><><><><>
    
    ----------------
    E3M1: Hell Keep
    ----------------
    
    Hit the switch in front of you at the start. Then, when the platform lowers, go
    to the door across from you. To the left and right of the door are switches.
    Hit the one on the left, and the door will open. Go through the door, and turn
    right. Open the door, and kill the enemies in here. Then from the door, go
    right and open another door. Follow the hallway to another door, killing any
    Demons. When you get to the door, open it, and open the door across from you.
    Kill all the Imps in this room, and the next door is the exit door. Before you
    open the exit door, check the walls to the left of the exit door until you find
    the secret. In the secret room, there is a Stimpack, Shotgun Shells, and a
    Rocket Launcher. Now open the exit door, collect the health and ammo in here,
    and go through the exit teleporter.
    
    ------------------------
    E3M2: Slough of Despair
    ------------------------
    
    At the start, keep to the left hand wall and just keep running along it until
    you get to the Blue Key. Then turn around, go straight, and when you're out of
    the alcove, take 2 lefts into another one. Walk up to the wall in front of you.
    Kill the Lost Souls that were behind the wall (or avoid them), and go into the
    room they were in. Open the Blue Door in here, hit the switch, turn around, go
    right, grab the health and ammo, and get to the exit teleporter.
    
    ------------------
    E3M3: Pandemonium
    ------------------
    
    On skill levels 4 and 5, there will be a Demon in front of you. Kill it,
    otherwise get out of your starting alcove, turn left, and then right up the
    stairs. Kill the Imps in here, hit the switch on the north part of the room,
    and the pillar behind you will lower, containing the Shotgun. With your back
    against the last stairway you took, go straight, and then take a right, going
    up a different set of stairs. Up here, go right, and work your way around over
    here until you see a pit below you. Jump in it, go straight, down the stairs
    into a Silver Room. Go right and grab the ammo and the Blue Key. Now head back
    up the stairs, and hit the switch in this pit. Then the floor you're on will
    rise (don't jump off). At the top, take a left, and jump back into this
    familiar room (the room where we got the Shotgun).
    
    Now, with your back against the stairs we took to get up here at the start of
    the level, go straight, and then left up the only staircase we didn't take. Up
    here, go right again, and then work your way around until you find a pit below
    you. Jump in it, go straight, and collect the health. No go down the stairs in
    this ledge, avoiding the opening to the right as you progress. At the bottom is
    a Invincibility Sphere. Take it, go back all the way up (skip the opening),
    back into the pit. Now kill the Lost Souls and Former Human Sergeants here, and
    look around the other areas in this pit until you find a BFG (YEAH!!), and a
    Soul Sphere. Now go down the staircase again, and go to the opening we skipped.
    Then go all the way right, killing any enemies in your way. At the door you'd
    stop at, turn left up the stairs, and kill the Imps in here. In this room is a
    gray platform that has a ledge you can step on. It can trigger a secret. Here
    is a map to show how to open it up:
    
                                        |
              |    X    |               |  <-- Blue Door
              |---------|               |
           |--|_________|--|            |
           |_______________|            |
    
    Say the X is you. Get on the small ledge, and walk forward. A wall in front of
    you should open. Kill any enemies that appear, and grab the goodies behind the
    wall that just opened (the ledge is the --- part, and you walk up to the ___
    part that's shorter, and the other ___ part is another ledge).
    
    In this room also is the Blue Door. Open it, and go inside. Kill the Imps in
    here, and then open the exit door. In here, walk up to the exit teleporter.
    
    --------------------
    E3M4: House of Pain
    --------------------
    
    Collect the Rocket Launcher and Rockets in this starting room, and go straight,
    heading up the stairs. Once you get to the top, just follow the hallway to a
    door. Open it. Follow this hall to a bigger room, and kill all the enemies in
    here from where you are. Then, run up to the 3 switches in this room. Hit the
    one in the middle, and turn around to see a platform rise (it won't if the
    crushing pillar has lowered into the pit), and collect the Chaingun and
    goodies. Then, go back and hit the switch on the left, and turn around again
    and see a platform rise (like I said before, it won't rise if the crushing
    pillar has lowered into the pit). From the new platform that just raised,
    collect the Invincibility Sphere and health. No go back and hit the switch on
    the right. Then enter through the opening to the right of it. Follow this hall
    to another opening.
    
    Go through the opening, and go straight. Go through the next opening, and then
    go all the way straight in this large room (skip the two large openings to the
    right), and then there will be another opening to your left. Skip it, and go
    into the opening we're heading to. Kill the Lost Souls and the Baron that
    appears in here on skills 3 and up, and get the Blue Key in this opening we're
    in. Then turn around, get out of this opening, go right, and take another right
    into the opening we skipped. Get to the other end of the room to the Blue Door.
    Open it.
    
    Kill the Imps in this room, and go straight, opening the door (across from the
    Blue Door, not to the left, the wall across from the Blue Door is a door).
    Then take a left, and in this room is a blue square. Step on it a few times,
    and a door should open that we can't open on our own. When the door is open,
    run through it, and go right. Follow this hall to another room, turn right,
    kill the Imps in here, and run to the pillars that have switches. Go to the
    pillar on the left, and hit the switch on the west side of the pillar. Turn
    around, go right until you bump into a wall, and turn right again. Go through
    the opening we just opened, and get the Yellow Key. Now go back, and hit the
    west switch on the right pillar. Now go straight, and left until you hit a
    wall, and go right, into another opening we just opened. Now open the Yellow
    Door, and get the Red Key. Now return to the pillars, and hit the south switch
    on the right pillar. Now go right, take a left, and then right into this
    opening. Open the Red Door in this room.
    
    Go left, until you hit a wall. Turn to your right and kill the Lost Soul. Check
    the wall he was guarding, and it should open. Grab the Radiation Suit, turn
    around, run straight through the lava pit, grabbing the health if you need to.
    Then, run into the pit. Open the door down here. Follow the hall to the exit
    door, and then go through the exit teleporter.
    
    -----------------------
    E3M5: Unholy Cathedral
    -----------------------
    
    At the start, you can see 2 openings. Take the one on the left, and open the
    door inside. Go in, and grab the Shotgun Shells to your right. Then turn
    around, and follow the hallway to 2 doors. One of them leads to 4 teleporters.
    Go through that door, and walk on the teleporter. When you get warped to a new
    place, a door will open, and the room has power-ups, and a Demon or Baron
    (depending on the skill level). Go in the room the enemy came out of, and grab
    the goodies (this will add to your secret percentage). In each corner of this
    room is a teleporter. Take the teleporter in the northwestern part of this room
    (use your Automap for to find the exact teleporter).
    
    In this new room, kill all the enemies here. Heal yourself with the Medikits in
    here too. Also in this room are 2 doors next to each other. Take the one on the
    right. Go into the room, and follow the hallway to a red pillar. Walk through
    it from the south end, and then the wall in front of you will lower. Go into
    this room. In this room, there's a crushing pillar in each corner of the room
    with a switch behind it. Hit the switch under the northeast pillar, and then in
    the northwest part of the room, a platform will lower, containing the Blue Key.
    Now, behind the southwest pillar in this room is a teleporter. Go through it
    (the pillar locations are from the entrance of the room).
    
    Now, we're in this familiar room again. This time take the left door. Follow
    this hallway to the Blue Door, killing any Imps or Lost Souls in your way. Go
    through the Blue Door, go left, open the exit door, and go through the exit
    teleporter.
    
    -----------------
    E3M6: Mt. Erebus
    -----------------
    
    You need to be quick with my instructions on this level. At the start, go left,
    and cross the lava pit, and stop when you get top another platform. From where
    you are, look around for a staircase. Climb it, and when you get to the top,
    jump off to the floor in front of you. Kill the enemies here, and on this
    platform, collect the weapons, and the Invincibility Sphere. Once you collect
    the Invincibility Sphere, face the small platform where you got the weapons,
    and *run* right, onto another platform. On here, *run* to the wall with skull
    heads on it. From the wall, go left, then right, and jump into the pit. Now
    *run* straight, heading towards the teleporter in the small alcove. When you do
    teleport, open the door in front of you. You may pick up the Blue Key on easy
    skill levels, but it's not needed for these instructions.
    
    In this room, you NEED to be invincible, otherwise you can't do the next part
    safely. From the door, check all the walls to the left until one opens (the
    secret wall has a tiny candle in front of it). Inside the secret alcove, go
    through the teleporter. When you get teleported you here, turn around, and when
    you do, go *slowly* right onto a smaller ledge. Facing the wall, to the right
    on the smaller ledge, switch to your Automap and make your you (the arrow) has
    its back to the Blue Box. If you are, read this next sentence: YOU MUST STILL
    BE INVINCIBLE!
    
    Then, when your back is to the Blue Box, take out the Rocket Launcher, save
    your game (if you are invincible). If you are playing on Skill Level 1, hold
    Shift. Fire. Right when you fire, hold down. If you do make it to the box, jump
    in. On Skill Levels 2 and up, you don't need to hold Down or Shift. Getting
    here Invincible and making it in the box takes a lot of practice, so keep
    trying to get in the box. When you are in the box, hit the exit switch (this
    took you to the secret exit ;-)).
    
    --------------
    E3M9: Warrens
    --------------
    
    Hey, this level is a replica of E3M1! How cheap! Anyway, hit the switch in
    front of you. When the platform lowers, head straight to the door and hit the
    switch to the left of it. The door will open. Go through the opening to the
    right, and open the door. In this room, open the door to the right. Now, open
    the door at the end of this hallway. In this room, open the door across from
    us, and kill the Imps inside. The secret to the left of the exit door is still
    here. Open the secret wall and get the stuff. Now go through the exit door and
    step on the exit teleporter. Hey! The wall in front of us is lowering! Get to
    the other end of the room, grab the Blue Key, avoiding the Cyberdemon in here
    (you don't need to kill it, don't bother). If you can, grab all the new goodies
    in here, and when you are done, backtrack to the starting room, avoiding any
    new appearing enemies.
    
    In the starting room is a new alcove. Take out your BFG, and go through the
    alcove. Sooner or later, you'll teleport. When you do, take that BFG and kill
    the Cacodemons in front of you. If you have enough ammo, use it to kill the
    Former Human Sergeants that will ambush you from both the right and left. From
    where the Cacodemons were, go left and grab the Red Key. Turn around, go
    straight, and when you get to where the Cacodemons were, go left, and exit this
    room back into the starting room. Go to the door, hit the right switch (it is a
    Red Door, and you may need to hit it a couple of times), and go inside, through
    the exit teleporter.
    
    ------------
    E3M7: Limbo
    ------------
    
    At the start, go straight, into a bigger room. On the western part of the room
    is an opening. Go through it. Then, go left, and right. Follow this hallway to
    a blood pit. Pass it. After you pass the blood pit, there will be an alcove to
    your right. Go in and hit the switch. Turn back around and head right, and then
    get the Blue Key. Kill any Demons that come towards you. Now, backtrack your
    way out of this maze, to the big "O" room. Cross this room (or take the
    platform to get around safely), and go in the opening across from the one we
    just came out of (avoid any new enemies). In this room, there are 2 Blue Doors.
    Take the one on the left. Go through it (pick up the Shotgun Shells next to the
    Blue Doors).
    
    Cross the bridge in front of us, and still head straight. Jump into the small
    pit, and go straight. Kill the Cacodemon in here, and pick up a Radiation Suit.
    From the alcove we just came out of, take the opening on the left. In this
    small hall, go straight, getting into another room. Kill the Former Human
    Sergeant, and go straight into another opening. Now, follow this hall to another
    opening. Follow it to a teleporter. DO NOT GO THROUGH IT. Before it is an
    opening on the left wall. Go through it, and at the end of the opening, turn
    left into another platform. Kill the Former Human Sergeant on this one, collect
    the Cell Ammo, and pick up the Red Key. Open the Red Door in here, and flip the
    switch. Now turn around, go straight, and then right. Now go through the
    teleporter.
    
    You will be right near where the Blue Key was. Get out of here again back
    Into the large "O" room. This time, go through the opening to the left. To the
    Left and right of you, there are 2 pillars. On the northern part on both are
    small openings that lead to a teleporter (each pillar I tell you to go to will
    have a small opening leading to a teleporter). Get to the pillar on the left,
    and take the teleporter. On this platform, hit the switch. Now, take the
    teleporter back, and go through the teleporter on the eastern part of this
    room. When you do teleport, get the Yellow Key across from you, and take the
    teleporter back. Before leaving this room, get on the platform to the left of
    the opening, and kill the Demon. Grab the health and a Radiation on this
    platform, and now exit this room. Now go right, and through the opening. This
    time, go to the large blood pit we passed on the way to the Blue Key. Get to
    the pillar in this pit, and go through the teleporter inside. When you get to
    this room, go straight, and turn right and hit the switch. Get out of this
    room, and back in this huge blood pit, get out of here and go to the "O" room
    again. Get to the middle, and go through the teleporter inside the pillar.
    
    In here, go straight. Open the Yellow Door, collect the health, and hit the
    switch. Return to the teleporter. When you get to the "O" room again, go right,
    into here again. Instead of going left this time, go right, take another right,
    and then left, into the blood pit. In the blood pit, take the teleporter inside
    the pillar. In this room, open the Yellow Door, cross the bridge, open the exit
    door, and go through the exit teleporter.

    E3M8: Dis
    ----------
    
    Congratulations, you've made it to the final level of episode 3! Anyway, open
    the door in front of you. Go straight, and get out of the opening. Go right and
    kill and kill The Spider Mastermind. Here are some tips:
    
    1. If you have a BFG with at least 120 cells, you can use that to kill her. It
    will only take 2-3 blasts.
    2. On any skill level, you can have the enemies attack the Spider Mastermind to
    weaken her.
    3. In the center of the room, open the door. Inside is some Armor and a Plasma
    Gun.
    4. You can stay in the center room, and take potshots at the Spider Mastermind
    every now and then.
    5. Also, on the platform surrounding the level there are Rockets and Cell Packs
    if you need them. To get them, use the staircase in the east part of the room.
    
    Once you defeat the Spider Mastermind, congratulations!
    
    Once the Spider Mastermind is dead, you get a little story:
    ------------------------------------------------------------
    The Loathsome Spiderdemon that masterminded the moon bases and caused so much
    death has had it ass kicked for all time. A hidden doorway opens and you enter.
    You've proven too tough for Hell to contain, and now Hell at last plays fair -
    for you emerge from the door to see the green fields of Earth! Home at last.
    You wonder what's been happening on Earth while you were battling evil
    unleashed. It's good that no Hell-spawn could have come through that door with
    you...
    ------------------------------------------------------------
    
    After the story comes the "ending". You'll see the green fields of Earth with
    peaceful music playing. Also you'll see a bunny in the grass...how cute...until
    the music gets intense and you see a picture of a city blowing up. You'll even
    notice the dead bunny on a stick. Once the ending is over, press Escape, New
    Game, then select Thy Flesh Consumed as the episode. Then, select the skill
    level, and you start episode 4.
    
    
    <><><><><><><><><><><><><><><><>
    Episode 4: Thy Flesh Consumed
    <><><><><><><><><><><><><><><><>
    
    Episode 4: Thy Flesh Consumed, is only found in "The Ultimate Doom". If you
    don't have "The Ultimate Doom" and only have "Doom", then you do not have this
    episode (you go as far as the end of episode 3). So don't read this episode if
    you don't have The Ultimate Doom.
    There are patches to upgrade your Doom to The Ultimate Doom at
    www.doomworld.com, however. First, before you upgrade to Ultimate Doom, first
    upgrade your current Doom version to 1.9 (unless it's 1.9), and then upgrade to
    The Ultimate Doom.
    
    -------------------
    E4M1: Hell Beneath
    -------------------
    
    Collect the Shotgun in front of you, and head out of this room. Take a left,
    and go right, into another room. Kill the Imps in here. From where you just
    entered this room, Go all the way right and hit the switch. Now turn around,
    and exit this room. Kill any Former Human Sergeants that just teleported. From
    where you exited this room, go all the way straight, then left, and another left
    to an opening to the right. Go through this hall, and jump in the slime pit in
    front of you.
    
    When you get to the slime pit, turn right, and take another left, going up a
    set of stairs. Kill the Former Human Sergeants and Imps in front of you. Go
    straight, heading up another set of stairs, grabbing a Chaingun. At the top of
    the stairs, go left and grab the Red Key. Turn around, and go back down the
    staircase. When you get to the bottom of the stair case where you just took,
    activate the lift to your right. When you get to the top *run* straight to land
    on the platform in front of you. Now get to the Red Door across from us. Open
    it.
    
    Go straight to the wall in front of you. To the left and right of it are
    Paths to the same area. Take either one to an opening. Enter the opening to get
    the Blue Key (kill the Imps here too). Now exit the Red Door, and get back to
    the opening we took to get the Red Key. Go through the opening, go right, then
    all the way left to get to the Blue Door. Open it, and go through the exit
    teleporter.
    
    ---------------------
    E4M2: Perfect Hatred
    ---------------------
    
    Kill the 2 Former Human Sergeants in front of you at the start. Collect the
    health on this platform too. From where you started, kill all the Imps, Demons,
    and Cacodemons heading your way. Also from where you started, there are 2 sets
    of stairs in front of. *Run* through the one on the left to make sure you land
    on this platform. On this platform is a switch. Flip it. Turn around to see a
    new opening. *Run* to get to it.
    
    In here, kill the Imps and Former Human Sergeants near you. Jump into the pit
    and grab the Radiation Suit down here. Before you hit the switch, turn left. See
    that "triangle"? Here's a map if you don't know what I'm talking about:
    
         / \
        /   \_____
    
                                  / \
    The _____ is the switch. The /   \ is the triangle (you can see it in the
    Automap). Walk up to the triangular wall and you'll here a door open. Now, get
    to the switch. Before you hit the switch, save your game. Now, hit the switch.
    When you hit the switch, turn right and *RUN* to the rising platform. Follow it
    to the platform we didn't go to yet, and *run* again, to get across the small
    gap. Pick up the Plasma Gun, and a hidden door will open, containing a Baron of
    Hell, an Energy Cell Pack, and the Yellow Key. Kill that Baron with your new
    Plasma Gun, and get the Yellow Key. Now drop back in the pit again, and go
    through the opening. Go straight, heading to a teleporter. Go through it.
    
    You're back at the starting room again. This time, *run* through the staircase
    to the right. When you land on this platform, hit the switch in between the
    yellow bars (the Yellow Key is needed). When you hit it, turn to the right and
    kill the Lost Souls that just appeared. When they're gone, *run* to the
    platform they were on. Get the Armor and Rocket Launcher, and then on this
    platform, there's part of the platform in front of an opening. Once again,
    *run* to get to it. Jump in the pit below, and kill any Cacodemons and Spectres
    down here. If you want to save ammo, there's a Chainsaw you can get down here.
    When everyone is killed down here, explore this room for another opening that
    has a staircase. When you do find it, climb the stairs to a teleporter, but
    don't go through it yet. To the left of it is an opening. Inside is another
    Baron and a Blue Key. Take down the Baron, and get the Blue Key. Now go through
    the teleporter.
    
    You'll be at the starting room again. *Run* through the staircase at the left
    again. *Run* straight again, crossing to get to another platform. See that blue
    pillar? First, blow up the Barrel in front in of it, at a safe distance too.
    Then, open up the blue pillar (same thing as a Blue Door), and climb up the
    stairs. Behind a lump is a Cyberdemon. Ignore it (don't shoot it, and walk up
    to the door, and it will open by itself. Kill the Cacodemons in front of you.
    Then turn around, go back down the stairs. At the bottom of the stairs, go
    left, and take the teleporter. Save your game before you enter the teleporter.
    You will be where the Cyberdemon is. You should telefrag him, and he should be
    killed like that. Get the BFG here, and lower the lump. When it lowers, go
    right, *RUNNING* into the pit, following the right wall (be quick). If you were
    quick enough, you'll get to this opening. Go inside, and hit the exit switch
    (this took you to the secret exit ;)).
    
    -----------
    E4M9: Fear
    -----------
    
    At the start, open the door in front of you. Collect the Shotgun in here, and
    open the other door in here too. Kill the Former Humans in front of you, and
    from the door, hit the switches to the right and the left. When you do, turn
    back around, go through the doors again. When you get out of the second door, go
    straight, and when you get into a hallway, go right. When you get to a door
    (not the one to the left wall), turn right and face the gap to your right. See
    those pillars to the right that have openings in between them? Use this map:
    
              __
    |     |  / Y\
    |        \  /
    |     |  |  |
    |        |  |
    |     |  |  |
    |        |  |
    |     |_  _  _  _  _   _   _  _   _
    |
    |        X
    |________________________________________________
    
    Say the X is you. The Y is the Yellow Key. The spaces between the | and _ are
    openings you can run through. Now, see that opening in front of the pathway?
    Now, back up, and go through the opening and you'll be on the pathway. Cross it
    to the Yellow Key. Now, drop down to the pit below you. Down here, step on the
    teleporter next to you.
    
    On hard skill levels, you may telefrag a Baron when you get here. In this
    little "cage", flip the switch on the pedestal. Then, go right, then run to the
    door. Then, in here, take the staircase on the right, and kill the Former Human
    Sergeant at the top, and then open the door. Kill the Imps and Former Human
    Sergeants in here. From the door, go straight and take the lift down. When you
    get to the bottom,
    open the door in front of you. Go through, and then left. Follow this hallway
    to a door on the left wall. Open it. Go through. Follow this hallway to a
    Yellow Door, killing any Demons, Imps, Former Humans, or Cacodemons in your way.
    Open the Yellow Door, and get to the exit switch (don't flip it). Facing the
    exit switch, turn around, and check the walls. When part of the wall opens, get
    the Backpack inside. Now go back and hit the exit switch.
    
    -----------------------
    E4M3: Sever the Wicked
    -----------------------
    
    Collect the Shotgun Shells and Shotgun in front of you, and run straight into
    A pit. Kill any enemies down here. Now, go down the staircase, and kill any
    Imps and Former Human Sergeants down here. From the bottom of the staircase, go
    left, where you see 2 staircases (one goes up and one goes down). Head upstairs,
    and follow this hallway to a door. As you approach the door, a hidden door
    behind you will open. Kill the Imps inside, and grab all the goodies in here,
    everything you can get (this adds to your secret %). Then turn around and open
    the door. Kill any enemies in here, including that Baron on hard skill levels.
    When everyone here is dead, drop in the pit. Down here, get to the normal
    floor, not this harmful lava. On the floor we're on is a pedestal with a switch
    on it.
    
    Hit it. The platform in front of you will lower, containing the Red Key. Grab
    it, and turn around. Kill any enemies down here, and down here, follow the
    right hand wall to an opening. When you get to it go through. In here grab the
    Rocket Launcher. Now see the switch to the left? Face it then turn around and
    face the wall behind you. Open it like a door in go through. In here head up
    the stairs in front of you. At the top grab the Shotgun Shells, Rockets, and
    the Soul Sphere, head back down the stairs, and leave this place. Back in here,
    take either path to the teleporter (left or right), grabbing the Boxes of
    Rockets. Take the teleporter.
    
    When you teleport, kill the Spectre in front of you. Then, check the wall
    across the teleporter. It will lower. Run straight, outrunning these enemies.
    Over here, you have 3 paths to take. Take the one on the left. When you get to
    the wall, go left, and take another left, up the set of stairs. Kill any new
    appearing enemies here. From the set of stairs, go straight, and then turn
    right, up a staircase. Up here, head straight to get to a lift, leading up to
    where we started. When you get to the top, go left, and take a right into an
    "outdoor hall". In this hall, open the Red Bars, and kill any enemies here,
    including that annoying Baron. From where the Red Bars are, Go straight,
    towards that pillar in front of you. Behind the pillar is the Blue Key. Grab
    it. Now turn back around, exit this room, into the platform where you started
    this level. On this platform, go all the way left (don't fall off), towards the
    Invincibility Sphere. Grab it, and fall off this platform to the left. Then,
    fall off again, into the blood pit. Down here, open the Red Door. Go inside.
    
    From the Red Door, go left, and take the spiral stairs to the top. At the top,
    take a right, getting to a staircase. Take the staircase to the Blue Door. Open
    it. Go through it, and kill any enemies inside here. Follow this hallway to the
    exit teleporter.
    
    ------------------
    E4M4: Unruly Evil
    ------------------
    
    Open the door in front of you. Collect the Shotgun and Shotgun Shells in here,
    and kill the Spectres and Imps in here. When you do, take the lift across from
    the door we took. When you get to the top, open the door in front of you. Go
    straight, and jump into the pit on the northeast part of the room. After you
    get in, go left (from the door), and take the lift up back up here. Now, go
    straight towards the stairs, but to the right of it is a new opening. Go
    inside, kill the Former Human Sergeants, and grab the Red Key. Now turn around,
    go left, and go left again into another opening. Open the Red Door, and go
    through it.
    
    When you enter this room, go right, and hit the switch. Then, run left to the
    lowered lift. At the top, go right, and take the teleporter. When you get here,
    you might telefrag a Former Human Sergeant. Go right and hit the switch. Then,
    drop down here, and hit the switch again. Go left onto the lowered lift again,
    and take the teleporter to the left. Go left and hit the switch (you might
    telefrag a Former Human Sergeant again). Then, drop down, hit the switch again,
    and run left to the lift again. Now go straight, and through the exit
    teleporter.
    
    -----------------------
    E4M5: They Will Repent
    -----------------------
    
    At the start, go left, and take another left going downstairs, killing any
    enemies in your way. When you get to the bottom, go straight, and open the
    door. Go right, and when you get to an opening to the right, go in and open the
    door. In here, go straight, activate the lift, killing any Imps or Lost Souls
    in your way. When you get to the top, take a right and get the Red Key, and
    kill any Former Humans and Former Human Sergeants up here too. Now, drop back
    down to the floor below you. Down here, head right to the door. Open it and go
    through. In here, walk straight until a wall on you lowers. Down here, go right
    until you get to a gap. Once you get to it, drop in it. Down here, head left and
    grab the Radiation Suit. Now head up the stairs to the right.
    
    *******************************************************************************
    !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!IMPORTANT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    Right here is one of the most biggest shortcuts in the game. I recommend doing
    it, as it's really easy and skips you from most of the hard parts. If you wanna
    take it, read on. If not, skip all the walkthrough that's in the *s and keep
    reading.
    !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!IMPORTANT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    At the top of the stairs, turn right. Now, follow the left hand wall until you
    see an opening to the left of the pathway. Once you see it, drop down it. Down
    here, get the Soul Sphere and follow the left hand wall to a gap. Once you get
    to a gap, cross it. On this platform, cross the gap in front of you. You'll be
    in the room with a Yellow Door. See the window to the left of it? Back up, and
    *Run* through the window. You'll be in the exit room. In here, hit the exit
    switch (note that you skipped the Yellow Door as well!).
    *******************************************************************************
    
    At the top of the stairs, turn left. Open the door in front of you, and go
    through. In here, follow this hall to a Blue Key. Once you get to it, the floor
    you're on will lower. Now wait for it to rise back up again, and when it does,
    turn around and leave this room. Back in here, follow this path to a Blue Door,
    killing any Former Humans, Former Human Sergeants, or Barons of Hell in your
    way. Once you get to the Blue Door, open it, and go through.
    
    In here, kill all the enemies on the platforms. Now, cross the platforms to an
    opening. In here, walk straight and the floor you're on will lower. Down here,
    you'll be in the room with the Yellow Key. You have two options:
    
    1. Use a trick to get past the Yellow Door without the Yellow Key and get to
    the exit.
    2. Get the Yellow Key to open the Yellow Door and get to the exit.
    
    ???????????????????????????????????????????????????????????????????????????????
    If you chose number 1, position yourself in front of the window. Now back up,
    and *RUN* straight, running through the window. You'll be in the exit room. Hit
    the exit switch.
    ???????????????????????????????????????????????????????????????????????????????
    
    
    <><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><>
    If you chose number 2, head down the stairs and get in front of the Yellow
    Door. Now, head left. See that switch on the wall? Hit it, and it will open
    like a door, so go through. In here, check the wall to your left and a hidden
    door should open, revealing a Berserk. Grab it, and head through the teleporter
    to your right. In here, cross the pathway to the Yellow Key. Now, turn around
    and drop down to the pit in front of you. Down here, take the teleporter in
    front of you. Now, when you teleport, open the door in front of you (which is
    the switch on the wall). In here, follow the left hand wall to the Yellow Door.
    Once you get to it, open it, and go through. In here, hit the exit switch.

    E4M6: Against Thee Wickedly
    ----------------------------
    
    Grab the Shotgun Shells in front of you, and kill the Former Human Sergeant in
    front of you. Now work your way out of here into a larger room, killing any
    Imps, Lost Souls, or Former Human Sergeants in your way. When you do get into a
    larger room, you will see a platform having the Blue Key on it (you can't get
    it). Kill any enemies in here too. Facing the Blue Key, drop down into the pit
    in front of it, and go left getting to an opening. Go through it, and as you go,
    you'll see a floor with ammo and a Radiation Suit on it. Get the Radiation Suit,
    get into the blood river again going left. You will need to drop into the pit,
    but before you do, you'll see a pillar with a teleporter on top, accessed from 4
    different lifts around it (depending on which lift you take, it will teleport
    you to a different area). From our view, here's what we see:
    
              N

           W |__| E
              S
    ---------------------
              X
    
    Say the X is you. Take the "S" lift to get to the teleporter. When you do
    teleport, grab the Chaingun in front of you, and run to get to the platform
    across from this one. Kill the Former Human Sergeant and Spectres in front of
    you, and then go straight, heading up a set of stairs. Up here, grab the health
    and the Blue Key. Then go back down the stairs, go straight, and get into the
    blood river again. Go left, get on the platform where we got the Radiation Suit,
    and check the walls until a hidden door opens. Go inside, go straight, get past
    the first set of stairs, but go up the staircase after it. Check the brown wall
    in front of you, and it should open. Go inside, grab the Rocket Launcher, and
    kill the Baron (don't use that Rocket Launcher, or risk committing suicide).
    From where we entered, hit the switch on the right wall. Then take a left and
    open the door (it has a demon face on it).
    
    Kill the Imps and Former Human Sergeants in front of you, and go straight, and
    then hit the switch in between the Blue Bars. Turn around, and climb the stairs
    to the right to get the Yellow Key, killing that Baron on Hard Skill levels.
    Turn back around, and before you go into the pit again, here:

             S
    ---------------------
           X
    
    The X is you again. Drop down, and use lift W to take the teleporter. When you
    do teleport, go straight, follow this bridge to another room. In here, kill the
    Imps, Spectres, and Former Human Sergeants. See that pole in between the Red and
    Yellow bars? Walk around it to reveal a teleporter near the Red bars. Go through
    it. You will telefrag a Former Human Sergeant. Drop into the blood pit, kill any
    Cacodemons here, and grab the Radiation Suit if you need to. Down here, open the
    Yellow Door, kill the Imp, get the health, and hit the switch. Exit this room,
    go right, and take the teleporter. Now that the Yellow bars have been removed,
    run across the gap the get to the teleporter the bars were in front of. Take
    it.
    
    Go straight, and follow this hallway to the Red Key, killing any enemies in
    your way. Now turn back around, and exit this hallway. To the left a wall has
    lowered, with a Cyberdemon behind it. Kill it (you need to, otherwise you can't
    beat this level), using your Rocket Launcher and BFG. When you do kill it,
    *run* up a small ladder on this balcony, and cross the bridge to get to this
    room again (this room had the Yellow and Red Bars). Get back in the blood pit,
    and open the Red Door. Kill the Imp and Cacodemon in here, and hit the switch.
    Now get back out of this room and go left, taking the teleporter. Now with the
    Red Bars removed, get to the farthest to the right where the Red Bars were, and
    look right. You'll see a platform with goodies and a teleporter at the end.
    *Run* to get to the platform, get the goodies, and take the teleporter.
    
    When you teleport, you'll be on the platform where the Cyberdemon was. If he's
    alive still, kill him. If not, take a left, get up the stairs, get to the room
    past this one, and take the exit teleporter at the northeast part of this room.
    
    ------------------------
    E4M7: And Hell Followed
    ------------------------
    
    Get the Shotgun, and kill the Former Humans and Former Human Sergeants in front
    of you. Then go straight, and when you see 2 staircases to the left and right,
    take the one on the left. When you get to the top, go left, and kill the Former
    Humans in front of you. Then, get to the switch that the Former Humans was in
    front of, and hit it. The wall in front of you should lower. Go inside, and take
    the staircase on the right. At the top, go left, and get the Red Key on the
    platform, killing any Lost Souls or Cacodemons in your way. Exit this room from
    where you came from now.
    
    Just before the staircase in front of you is a staircase to the right. Go down
    it again, and at the bottom, turn left, and open the door. In here, jump into
    the pit across from you, killing the Former Human Sergeants in your way. In the
    pit, go left. Follow this hall to a floor with a Radiation Suit on it (kill the
    enemies in your way). From the Radiation Suit, turn left, and open up the Red
    Bars. From the Red Bars, go straight, and take the lift on the left. Kill the
    Former Human Sergeant on it. Get to the top using this lift.
    
    At the top, go straight, and hit the switch (watch out for the Baron up here on
    hard skill levels). The wall in front of you will lower, revealing another
    Baron and a switch. Kill or avoid the Baron, and hit the switch. From the
    switch, go straight, and fall onto the ground below you. From here, go
    straight and then left, crossing this new bridge. On the platform it leads to,
    get on the flashing square, and then a lump should raise with a switch on it
    (this is the exit switch). Hit this switch, and you're done with this level!
    
    ---------------------
    E4M8: Unto the Cruel
    ---------------------
    
    Congratulations, you've made it to the final level of Episode 4, and this game!
    Anyway, get the Shotgun in front of you, and kill the Imps around you. Then go
    down the stairs, and flip the switch down here, and the door to the left will
    open. Kill all the Former Humans , Former Human Sergeants, and Spectres in here
    (or let them fight). From the door we entered, go right, and follow this hall to
    a wall with a Demon head. Check it. It should open, revealing the Red Key. Turn
    back around to the door we entered to get here, and cross the bridge to get to
    this platform. On here, open the Red Bars, and kill the Baron. Also in this
    small room is a switch. Flip it. Now leave this platform and go back to the door
    we used to get here. Follow the other hallway to a Demon head. Check it. Go in,
    and take the teleporter.
    
    Kill the Imps and Former Human Sergeants in here. From the teleporter, go
    straight, and head up the staircase. At the top, go left, and follow this bridge
    to another platform. Kill the Baron on here that appears on hard skill levels,
    and get the Armor. In here, go down the stairs, and follow this bridge into
    another room. Kill the enemies in here, and hit the switch in here. When you do
    hit it, take the lift down to the left.
    
    Down here, follow this hall to the Yellow Key, killing any enemies in your way
    (watch out for 2 Barons on hard skill levels). When you get the Yellow Key,
    turn around, go straight, and hit the switch to the left. Ride this lift up
    again, and up here, backtrack your steps to the teleporter we used to get here.
    
    In here, open up the Demon face door. Now cross the bridge to the center
    platform again, and this time open the Yellow Bars. Kill the Baron in here, and
    hit the switch in this small room. Now, instead of crossing the bridge we used
    to get here, cross the new bridge on this platform. Climb the stairs, and open
    the door.
    
    In here, walk around the pillar to get to the Spider Mastermind. Kill it. Here
    are some tips.
    
    1. Use your Rocket Launcher or BFG to kill her. It only takes 2-3 BFG hits to
    kill her.
    2. On hard skill levels, there will be a few Barons in here too. You can use
    them to weaken/kill the Spider Mastermind.
    3. Near the Spider Mastermind is a hidden area with a BFG and some ammo. Check
    the walls while she's in a fight with an enemy so you don't risk being killed.
    
    When you do kill the Spider Mastermind, the pillar we walked around will lower,
    revealing the exit teleporter. Take it, and you've finished the game!
    Congratulations on defeating her!
    
    Once you step on the exit teleporter, you get a little story.
    
    ------------------------------------------------------------
    The Spider Mastermind must have sent forth its legions of Hellspawn before your
    final confrontation with that terrible beast from Hell. But you stepped forward
    and brought forth eternal damnation and suffering upon the horde as a true hero
    would in the face of something so evil. Besides, someone was gonna pay for what
    happened to Daisy, your pet rabbit. But now, you see spread before you more
    potential pain and gibbitude as a nation of Demons run amok in our cities. Next
    stop, Hell on Earth!
    ------------------------------------------------------------
    
    A few seconds after the story is done, you can see a screen of what happened
    after the ending from Episode 3. You'll see the Doom marine with a Shotgun in
    one hand and holding the head of his dead bunny in the other hand. Someone's
    going to get their ass kicked.
    
    --------------------------------------------------------------------------------
    
    9.) The Ultimate Doom Secrets
    ----------------------------------------
    Now I've decided to add a secrets section, which will really make my Ultimate
    Doom Walkthrough Ultimate. This will cover every secret in the game. You can
    use my Walkthrough for parts of this section too.
    
    
    <><><><><><><><><><><><><><><><><>
    Episode 1: Knee-Deep in the Dead
    
    <><><><><><><><><><><><><><><><><>
    
    ------------------------
    E1M1: Hangar: 4 Secrets
    ------------------------
    
    1. In the room with a zig-zag floor, walk up to the door, but check the walls
    to the right of it. One should open, so go through. In here get the health and
    ammo, then follow this hall to an opening, and go through. Out here, get the
    Combat Armor in the middle of the room.
    
    2. Now go back and open the door, and in here, get to the exit door. Then turn
    around an go back to the room with the zig zag floor. Remember the platform
    with the Imp on it? It has lowered. Go inside and get the Medikit, Shotgun, and
    Shotgun Shells.
    
    3. From Secret 2, get back to the Zig-Zag room. See the light posts at the
    north part of this room? Get to them. Now, turn around and face the opening
    that lead to Secret 2. Facing the opening, and with your back in between the
    light posts, back up. You should then see a wall lower in the Secret 2 room.
    *RUN* to the lowered wall, get on it, and ride it to the top. Up here is a
    hallway of armor bonuses and a Box of Shotgun Shells, and an opening back to
    the zig zag room.
    
    If the wall/lift raises before you get to it, get back to the light posts, back
    up a little bit, and the wall/lift will lower again (there is a tripwire you
    must step on that's between the opening in the light posts).
    
    Note: At the start, go to the room to the left. Between the staircase are
    pillars. On the east part on the right one is a switch. Flip it. Get back into
    the starting room, and to the right of the windows is a new opening. Go through
    it, and you'll be in the room with the Combat Armor. This can cut through the
    whole level almost. This is an Ultimate Doom Only Secret (this "secret" does
    not affect your secret %).
    
    -------------------------------
    E1M2: Nuclear Plant: 6 Secrets

    your right. Hit the switch on the pillar in here, and leave this room. Across
    from you is an opening to a maze. Go inside. In the southeastern part of this
    maze is part of a wall in between 2 poles. Check it, and it should open,
    revealing a Backpack.
    
    4. Also in this maze is a room with a flashing light. Shoot the wall where the
    light is flashing, and go inside. Going in here is a secret.
    
    5. In here, get past the first 2 sets of stairs (don't go up any further).
    Check the walls after the second set of stairs, and a hidden door should open.

    6. Exit this maze, and go left, heading up the stairs. Cross this bridge, and
    get to the opening where 3 Medikits are. Before going down the lift, check the
    walls to the left of it, and part of it should open. Go inside (this has health
    and armor bonuses), and here's your final secret!

    stairs, and you'll hear the sounds of 2 platforms dropping (both are in front
    of "Computer Walls". At the top of the stairs, go left, then right, and you
    should see one of the dropped platforms. Get on it, and when it gets as high as

    -----------------------------------
    E2M2: Containment Area: 12 Secrets
    -----------------------------------
    
    1. At the start, go straight. When you have the chance to go right or left, go
    right. Follow this path to a wall (not any crates). At the wall, go all the way
    left, to a crate. Walk up to the crate, and it should lower. Inside is an
    alcove with Shotgun Shells.
    
    2. From the Shotgun Shells, go left to an opening. In here, go left to the
    center of the room. From where you came, go right, heading to a door. Before
    the door is an alcove to the left. Go in and hit the switch. The door will
    open.
    
    Go inside, and the stairs will raise. Up here, go left, and then take another
    left. You'll see the Yellow Key across from you. Follow the lights on the
    ceiling to reach it (this isn't a secret). Turn around, and then go straight.
    Stop at the first opening to the left. Get on the lifts going up and down, and
    behind one of the lifts is a hidden opening. Go in and here's the secret. This
    room has a lot of health bonuses inside.
    
    3. From secret 2, follow this hall to the crate maze again (go through the
    opening across from the door we opening by flipping a switch). In here, go
    straight, and then left. Open the Yellow Door. In this room, open the other
    door. In here, go right, and hit the switch. Turn around, and the pillar will
    lower, containing the Chaingun. Get it for a secret.
    
    4. Get back into the crate maze, and search for another Yellow Door. In here,
    *run* all the way straight, getting the Backpack before it's too late. Now 3
    pillars will raise. Hit the switch on each. Now go through the opening, and
    turn left, into a new opening. Here is a secret.
    
    5. Go through the opening to the right of this one. Get the Rocket Launcher in
    here.
    
    6. Go through the opening to the right of this one. Here lays another secret.
    
    7. Now exit this room, and in the crate maze, get to the room where we flipped
    a switch to open a door. Go through the door again, and up the stairs. Up here,
    go right. To the right of this opening is another room. Go through it, and then
    straight until you hit a wall. Then go right, and go through the opening. Going
    in this hall counts as a secret. Follow this hall to a Backpack.
    
    8. When you pick up the Backpack. You will be trapped in here, and a wall in
    front of you will open, having enemies. Go in the new room, and you have a
    secret.
    
    9. From secret 8, check the walls in here until a hidden door opens. Go inside.
    In this hallway, check the walls to the right until a hidden door opens. Go
    inside, get the goodies, and you have a secret. To get out of this trap, get
    out of here, follow the hallway to you hit a wall/door, and check/open it.
    
    10. With your back at the Red Door, go left, and skip the first opening. Then
    go inside the second opening. On one of the pillars is a switch. Hit it, and
    go left to the lowered pillar. It has a Plasma Gun in it. Be warned that this
    switch only works once, so if you miss the Plasma Gun, you can't get it. But I
    have found a way to get this weapon if you missed it lowering. Face the pillar
    the Plasma Gun is on. Next to it is a switch above you. If you get in front of
    the pillar and face the switch at an angle, you can hit it. Get closer to the
    switch while facing it at an angle. If you keep hitting Spacebar, you'll
    probably hit it, causing the pillar to lower for good. Now you can get Plasma
    Gun.
     S---------|
     S PG |
     S---------|
     X
    
    Say the X is you. The rectangle ahead of you is the pillar, and PG is the
    Plasma Gun. The S's are the switch which is high above you. But if you get up
    to the switch (even if you are below it) and hit Spacebar when hitting it at an
    angle, you have a chance to hit it.
    
    11. Facing the Red Door, get to the crushing ceiling hall. In the crushing
    ceiling hall, there is an opening to the left of one of the crushing ceilings.
    Go through the opening, and follow it to a Chainsaw. Pick it up.
    
    12. Get through the crushing ceiling hall, and follow this to a room with the
    Blue Key. Before crossing the slime pit to get it, go right, and "hug" the
    corner over here. To the right of the Blue Key, a wall will lower once,
    containing a Soul Sphere. So save your game before you attempt this one.

    follow this hall to two doors. One leads to another room, and the other room
    leads to a set of teleporters. Go through the door that leads to the set of
    teleporters, and take the teleporters. AGAIN, you'll be back at the courtyard.
    When you get here, a hidden door on the building to the left of you will open.
    Go through the new opening. In this secret room is a Box of Shotgun Shells, a
    Box of Bullets, and an Invincibility Sphere.
    
    ----------------------------
    E3M6: Mt. Erebus: 4 Secrets
    ----------------------------
    
    1. At the start, go right, and cross the lava pool to another area of this
    level. When you get here, there will be a staircase leading to a door (on a
    building) across from you. Climb the stairs, and open the door. In this room,
    drop down. Down here there is a teleporter to your left and right. Take the
    teleporter to your right. You'll be teleported to a platform on this building.
    On this building lies an Energy Cell Pack and a Plasma Gun.
    
    2. From secret 1, switch to your Automap. Just to the left of the building
    you're on is another building. Jump off this platform, and get to the building.
    From the south end of this building, open the door, and go inside. Get to the
    Berserk. Pick it up. From the Berserk, go right (with your back facing the
    door), until you get to a wall. Check this wall, and it should open, revealing
    a secret, and an Energy Cell Pack.
    
    3. From secret 2, turn around, and go straight until you get to another wall.
    Check this wall, and it should open. Go through the teleporter. When you
    teleport here, save your game. See that pillar with a Chainsaw on it just next
    to you? Well run across this platform to get to the pillar. When you get to the
    pillar, you get credit for a secret, and you can get a Chainsaw.
    
    4. From secret 3, drop down from this pillar. Down here, take the teleporter
    in the south end of the building we jumped off of to get to secret 3. When you
    teleport, you'll be back here. Open the door in front of you. In here again,
    take the teleporter in the west part of this room. You'll be teleported back up
    here. The secret is getting into the blue box with a switch inside. Use my
    Walkthrough for this part, but when you get in, you can go to E3M9, and you
    get a secret (using an Invincibility Sphere for this part is highly suggested).
    
    -----------------------
    E3M7: Limbo: 4 Secrets
    -----------------------
    
    1. At the start, get into the big room across from you. In here, go through the
    opening at the west part of this room. When you get in here, use my guide to
    get to the Blue Key. Using my guide, just before the Blue Key are two alcoves
    (one on land and the other in the lava pit). Hit both switches. Now go and get
    the Blue Key. Once you have the Blue Key, turn around, and go straight, to the
    to alcoves with switches in them (don't go in them).
    
    From these two alcoves, go straight, past the lava pool. Over here, you'll see
    two openings to your right. Skip the first opening, and go through the second
    opening. Going in this room counts as a secret (it has a few armor bonuses).
    
    2. From secret 1, exit the opening you came from. Out here, turn right, and you
    should see a new opening to your left. Go through it. In this secret room is a
    Rocket Launcher and a Soul Sphere.
    
    3. Get out of the secret 2 room, and exit this maze, back into the big "O"
    room. In here, get to the other end of the room, through this opening. In this
    room, open the Blue Door to your left. In here, cross the bridge in front of
    you, and then get to the other end of the room. Over here, drop in the small
    pit. Down here, go straight, and get to this room. In here, grab a Radiation
    Suit, and then with your back facing the opening you just game out of, take the
    opening to your right. In this part of the maze, work your way to another room.
    
    In this room has a teleporter (don't go through it), and a BFG (and a secret).
    
    4. From secret 3, get back to the room where you got your Radiation Suit. In
    here, with your back against the opening you just came out of, enter the
    opening across from you. In here, work your way to another room with Radiation
    Suits. In here, enter the opening across from you. In here, follow this hall to
    another opening. Go through it. As you go, you'll see a teleporter across from
    you (don't go through it). Just before the teleporter is an opening to the
    left. Go through it. When you get out of this hall, turn left, and grab the Red
    Key in this room. In this same room, open the Red Door, and hit the switch.
    
    Now turn around, and go straight until you hit a wall. Then turn right, and go
    through the teleporter. Get out of this room you're in, back into the "O" room.
    Again, get to the other end of the room, and through the opening. In here, now
    open the Blue Door to the right. In this room, follow the wall to your right to
    an opening. Go through. Follow it to a switch, Hit it, leave this hall, and
    *run* to the other end of the room (the switch made the wall lower for a few
    seconds), and hit the switch over here. If the wall rises on you, just check
    the wall you raised, and it will lower.
    
    Now with the switch hit and the wall lowered, go left (with your back facing
    the switch you hit), and cross the new bridge. See the pillar over here? It has
    an opening leading to a teleporter. Go through the opening, through the
    teleporter. When you teleport, you'll be on a platform across from the Yellow
    Key. This is a secret. On this platform is a Plasma Gun, Armor, and some other
    goodies.
    
    ---------------------
    E3M8: Dis: 0 Secrets
    ---------------------
    
    Here is another secret-free level.
    
    ------------------------
    E3M9: Warrens: 1 Secret
    ------------------------
    
    1. This is a replica of E3M1, right? So the secret is still in the same place.
    Just before the E3M1 exit door, check the walls to the left of it. A hidden
    door should open, containing a Rocket Launcher, 4 Shotgun Shells, and a
    Stimpack.

    Episode 4: Thy Flesh Consumed
    <><><><><><><><><><><><><><><><>
    
    ------------------------------
    E4M1: Hell Beneath: 2 Secrets
    ------------------------------
    
    1. At the start, go straight, and jump into the slime pit. Down here is a
    hidden lift. Here's where it is:
    
                        ____              ________
                   Red  |   | Slime Pit S|   |    |
                  Door  |   |     X      |   |-------
                        |   |____________|   |
                        |                    |___
                        |____________________|   |___|
                        |    Starting Room   |
    
    Say the X is you and the S is the secret. Check the platform the S is next to,
    and the hidden lift should lower. Behind the lowered lift is a small room with
    a Rocket Launcher and 2 Box of Rockets. Go in that room, and get the goodies.
    When you get the goodies, check the walls to the left of where you entered this
    room, and a hidden door should open. In this room is a secret, and you can take
    either teleporter to get out of here.
    
    2. When you have the Red Key, open the Red Door. When you enter, you should see
    a torch to the left and right of you. Get in front of the torch on the left
    (face the torch), and press the space bar on it. Now, the wall behind you
    should lower. When it's finished lowering, step on the new "Nin" logo on the
    floor. You should get credit for a secret (walk around the middle of the logo
    to make sure you get a secret).
    
    Now, when you try to leave this room, you will be trapped (the floor in front
    of the Red Door will rise). To get out of here, hit the switch on the new wall,
    and the wall will lower back into a floor.
    
    --------------------------------
    E4M2: Perfect Hatred: 3 Secrets
    --------------------------------
    
    1. At the start, *run* across the stairs to the left to get to the other
    platform. On this platform, hit the switch on the wall. Now turn around, and
    *run* to get through the new opening you see. In here, drop into the lava pit.
    When you drop down, turn around, and you should see a switch. Before you hit
    it, walk up to the pole to the left of the switch, and you should hear the
    sound of the door opening.
    
    Now hit the switch, and *run* all the way right to get to the rising platform
    before it's too late. When it's done rising, follow it to another platform.
    *Run* across the gap to get it. Over here, pick up the Plasma Gun. A door will
    open, containing the Yellow Key. Grab it. Now turn around, drop into the lava
    pit. Down here, go through the opening and up the stairs at the north part of
    this room. Now go straight towards the teleporter. Before you go through the
    teleporter, check the walls to the left of it until a hidden door opens. In
    here is a Berserk and an Energy Cell Pack. Now go through the teleporter (it
    brings you back to the start).
    
    2. Using my Walkthrough, get to the Blue Key. When you have it, use my
    Walkthrough to get to the Blue Pillar. Open it. Now climb up the stairs. When
    you get to the top, walk forward to the door and it will open. When it opens,
    turn around, go back down the stairs. When you get to the bottom, go left, and
    go through the teleporter. You'll telefrag the Cyberdemon, and you'll get a
    secret, and a BFG.
    
    3. From secret 2, use my Walkthrough to get to the secret exit. When you get to
    the secret exit switch room, you'll also get credit for a secret. The secret
    exit leads to E4M9, Fear.

    E4M3: Sever the Wicked: 20 Secrets
    -----------------------------------
    
    !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    There is a slight error in this level. There were meant to be 22 secrets in
    this level, but 2 were missing in this level. So the highest % number you can
    get in this level is 90%.
    !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    
    1. At the start, go straight, and drop down to the ground in front of you. Down
    here, go down the staircase in front of you. In here, go left. You'll see a
    staircase leading up, and one leading down. Take the staircase that heads
    upstairs. Up here, follow this hall to a door. As you approach the door, a
    hidden door behind you will open. Go through the new opening. In here lies
    useful goodies, and a secret.
    
    2-19. From secret 1, go back to the door we were approaching, and open it. In
    this room, drop down to the pit in front of you. Down here, go right, then
    left. You should see an opening with a switch and a Rocket Launcher in it. Go
    in the opening. In here, check the wall across from the switch, and it should
    open. In here, climb the stairs to the top. As you climb up the stairs, your
    secret % will be raising until you get to the top.
    
    20. From the top of the stairs of secrets 2-19, go in the room the staircase
    leads to. In here is another secret, and it has a Soul Sphere and some other
    goodies.
    
    -----------------------------

    front of you, and get on it. When the lift rises face the door in front of you,
    go left, and follow the hall to an area of torches. Over here, get in front of
    the Green Torch. Facing the green torch, hit the spacebar, and the floor you're
    on will lower. Down here, go through the new opening, and stay where you are.
    When the floor rises again, go through the only opening you can access here. In
    this room is a teleporter, a secret, a Rocket Launcher, and a Box of Rockets.
    
    2. From secret 1, take the teleporter. When you teleport, turn around, and open
    the door. You'll be in this room again. In here, go right, and follow the hall
    to the torches again. Again, get in front of the Green Torch, and press the
    Spacebar. The floor will lower again. Go back through the opening, and in this
    room, take the opening to the left this time (instead of having the floor rise
    again). In this room is a teleporter, a secret, and a Berserk.
    
    ----------------------------------
    E4M5: They Will Repent: 2 Secrets
    ----------------------------------
    
    1. From the start, use my Walkthrough to get to the Red Key. In the same room
    where you got the Red Key, open the Red Door. In this room, check the walls to
    the left of the Red Door until a hidden door opens. This secret room contains 2
    Stimpacks.

    larger room. In here, get to the northwest part of the room. Over here, there
    are two openings (one near the wall and one to the left of that opening). Go
    through the opening that is not next to the wall. In this opening, go straight,
    and just walk through the wall, and you'll be in a secret area. In this secret
    area has a few Energy Cells and a Plasma Gun.
    
    2. From secret 1, get back into the larger room. See that platform with the
    Blue Key? Facing the Blue Key, drop down into the pit in front of it, and head
    right. Now follow this hall until you see a non-toxic floor to your right. Get
    on it. On here, check the walls and a hidden door should open. In this secret
    room is an Invisibility Sphere, and a lift. Lower the lift, ride it up, and at

    -----------------------------------
    E4M7: And Hell Followed: 4 Secrets
    -----------------------------------
    
    Here is another level with an error. There are supposed to be 4 secrets in the
    game, but there are only two for some strange reason, and you can only get 50%
    secrets maximum. Anyway, here goes.
    
    1. You need the Blue and Yellow Key for this one. At the start, go straight,
    and go down the stairs to the right. Down here, go left, and hit the switch to
    the right (this is a door, and go through. In here, follow this hall to a
    switch. Hit it, and a pillar to your right will lower, containing a Soul Sphere.
    Pick it up, and the wall in front of you will drop, revealing the Blue Key.
    
    Now, exit this room. Back here, go up the stairs to the left. When you get to
    the top, go up the stairs in front of you. Up here, go left, and hit the switch
    (this is another door, and enter this room. In here, go up the stairs to your
    right. Up here, go straight to a wall with a demon head on it (this is the Blue
    Door). Open it. Go through the teleporter across from you.
    
    When you teleport to this room, pick up the Yellow Key in front of you. Now
    turn around and go through the teleporter. You'll be teleported in front of the
    Blue Door. In here, go straight until you get to the 4 sets of stairs. Take the
    staircase to the right, and hit the switch (this is the Yellow Door).
    
    In here, go down the stairs to another room. In here, get to the goodies to
    your right. Over here, check the walls until a hidden door opens. This secret
    room has some useful goodies.
    
    2. From secret 1, turn around, and get to the other end of the room. Hit the
    switch over here. When you hit the switch, turn around, and go through the
    opening to the left, and go down the stairs. While going down these stairs,
    you'll see an opening to the right. Go through it, and this secret room has a
    few useful goodies.

    E4M8: Unto the Cruel: 1 Secret
    -------------------------------
    
    1. At the start, turn left. You'll see two bodies being hung by their necks
    (one is near the wall and one is to the left of that one). Get in front of the
    body that is not next to the wall. When you get in front of it, push the
    space bar. The floor the bodies' above should lower, and so should the wall to
    the left of it. Go through that new opening, and in this secret room is a
    Chaingun and other useful goodies.
    
    ----------------------
    E4M9: Fear: 2 Secrets
    ----------------------
    
    1. At the start, use my Walkthrough to get to the Yellow Key. When you have the
    Yellow Key, drop down to the water below it, and take the teleporter. When you
    teleport, turn around and hit the switch. When you hit the switch, go down the
    small staircase to your right, and open the door across from you.
    
    In this room, go up the stairs to the right, and at the top, open the door. In
    this room, turn all the way around, facing the door you just entered. Check the
    walls to the left of the door, and a hidden door should open. This secret room
    has a Berserk.
    
    2. From secret 1, get your back on the door we entered to get to this room (not
    the secret 1 door). From here, use my Walkthrough to get to the exit switch.
    Before you hit the switch, turn around, and check the walls, and a hidden door
    should open. This secret room has a Backpack.
    
    --------------------------------------------------------------------------------
    
    10.) The Ultimate Doom Bugs and Errors
    ----------------------------------------
    Here are some known bugs and errors I found in the game. If I forgot any, tell
    me!
    
    1. In E4M3: Sever the Wicked, the maximum secret % score is 90. This is due to
    1 secret found alone, and 19 found on a staircase. The other 2 secrets are on a
    pair of torches near the secret stairs, and the player cannot step into the
    torches because both torches occupy the secret areas and both areas are too
    small for you to step in.
    
    2. In E4M7: And Hell Followed, the maximum secret % score is 50. This is due to
    that the player cannot step into 2 of the secret areas without using any cheat,
    only 2 secrets are accessible without cheats.
    
    --------------------------------------------------------------------------------
    
    11.) Doom II Walkthrough
    ----------------------------------------
    Now, here's the walkthrough (note that this walkthrough is not useful for skill
    level 5)! Also some enemies I tell you to kill in this game may not be there
    because of the skill level so if you don't see an enemy I told you to kill in
    this guide, then you're playing a low skill level.
    
    ------------------
    Level 1: Entryway
    ------------------
    
    All right, before you jump off the ledge you're on, go left and pick up a
    Chainsaw. Now go back to the starting point and jump off the ledge. Equip your
    pistol, and shoot the Former Humans. Pick up the ammo and health in here, and
    go up
    the stairs into an opening. In here, turn right, killing the Former Humans and
    the
    Imps on hard skill levels. Also, in this hall, go through the opening just to
    the right of the health potions.
    
    Follow this hall to another room. In here, lower the lift to your right. Kill
    the Former Humans/Imps here, and once the lift rises to the top, check the
    walls up
    here until a hidden door opens. When it opens, kill the Imps/Former Humans in
    front
    of you. In this little secret room is a switch. Hit it. Now get to the edge of
    the life (don't get off). See that square platform? Back up, then *run* off the
    lift and try to land on it. When you do, go to the opening through your left
    and follow the hall back to this hallway.
    
    In here, turn right, towards the health potions. You'll see a new opening
    across from you. Collect the health bonuses and go through the opening. Pick up
    the Rocket Launcher (switch back to Pistol). Now turn around and go back
    through the opening to your left, and use the hall to get to the other room.
    
    In here again, go all the way left until you hit a wall. Now turn left and face
    the exit door. Facing the exit door, turn around and go through the opening
    across from you. Out here, go all the way right and pick up the Shotgun, and
    kill or avoid the Imps in here. Now go back into the other room, through the
    exit door, collect the health in here, and hit the exit switch.
    
    --------------------
    Level 2: Underhalls
    --------------------
    
    From the start, kill the Former Humans across from you with your Pistol or
    Shotgun.
    Now get to the other end of the room, and open the door. Kill the Former Humans
    in
    here, and go left to an opening. Kill the Former Human Sergeant here, and flip
    the switch he was guarding. Now go back to the starting room. Back in this room,
    get into the water and go right, through the new opening. Follow this hall until
    you see an opening to a door to the left, and kill the Former Humans and Former
    Human Sergeants in your way. Go through the opening, and open the door. In here,
    kill the Former Humans and Former Human Sergeants in front of you. Collect the
    health and ammo in here, and kill the Former Humans and Former Human Sergeants
    at
    the other side of the room too. When they're dead, pick up the Super Shotgun.
    Now leave this room.
    
    Back in this water hall again, go left until you see a wide staircase to the
    left. Climb it and kill the Former Human Sergeants up here. From the stairs, go
    all the way left, then go right until you hit a wall. Facing the wall, turn
    right, and you'll see a window. Get in center with it, then *run* across the
    small gap to get through the window. In here, kill the Former Human Sergeants,
    and go up the stairs to the Red Key.
    
    From the Red Key, check the walls to the left of it until a hidden door opens.
    Kill the Former Human Sergeants in here, grab the Combat Armor, and go through
    the
    teleporter. You'll be warped back to the level's starting point. From where you
    are, get to the other end of the room again, and open to door. In here, go
    right, and press the Spacebar in front of the red bars to remove them. Kill the
    Former Human Sergeant and hit the switch he was guarding. Now leave this room
    back into
    the starting room.
    
    In here, get in the water, and go left, through the new opening. Kill the
    Former Humans and Former Human Sergeants in your way, and follow the hall to
    the second
    opening to the right. Go through, kill the Former Human Sergeants, and go
    through the
    opening in here. In this room, you'll see two gaps to drop down in the corners.
    One to the left, and one to the right. Go down the one to the left. Down here,
    kill the Imps, Former Humans, and Former Human Sergeants, and get the Blue Key.
    Once you get
    it, open up the normal door in here. In this room, kill all the Imps,
    Former Humans, and Former Human Sergeants here, and open the Blue Door. Go
    through. Go up the
    stairs, through the other Blue Door across from you. Open it, kill the Shotgun
    Guys in here, collect their Shotguns, and hit the exit switch.
    
    ---------------------
    Level 3: The Gantlet
    ---------------------
    
    From your starting point, open the door in front of you. Collect the Shotgun,
    and drop down to the pit below. Kill the Imps down here, and go through the
    opening, and up the stairs. At the top, go left, and you'll see a lift to
    your right. Press the Spacebar to lower it, and get on board. When it reaches
    the top, kill the Imps and the Former Commando (on high skill levels). When
    that's done, go down the stairs in front of you, and then walk up the staircase
    in front of you, then go down the one in front of you.
    
    In here, collect the Chaingun, then go up the next staircase and collect the
    Blue Key. Now open the Blue Door to the left. In here, kill the Former Humans
    and
    Former Human Sergeants in front of you and follow the hall to a switch. Hit it,
    and Open
    the Blue Door to your left. Now, back here, go right down the stairs, then up
    the staircase in front of you. You'll be in front of the lift. Now turn right,
    and you'll see that a bridge has raised. Follow it to a teleporter, and
    take it.
    
    You be teleported in front of a door. Collect the health, and open the door. In
    here, drop down to the pit below, and down here, pillars will lower. One of
    them reveals the Red Key. Take it. Kill any Imps or Demons here. Also down here
    are two switches next to each other. Hit the one to the right and a lift to the
    left will lower. Take it to the top and follow it to the Red Door. Open it,
    kill the Demon in front of you, and hit the exit switch.
    
    -------------------
    Level 4: The Focus
    -------------------
    
    From your starting point, open the door in front of you. Kill all the Former
    Humans
    and Former Human Sergeants to the left and across from you. From where you are,
    go all
    the way straight up a staircase (watch out for the Former Commando on high
    skill levels). Up here, hit the switch, and go back down the stairs, then go
    right, through a door. Open it.
    
    In here, go right, and follow the hall to the Blue Key, killing any Imps in
    your way. Now turn around, and follow the hall to the Blue Door. Open it. In
    here, follow this dark hall to another room, killing any Imps in your way.
    You'll get to a room with crates and Imps. Kill all the Imps, and look around
    for a switch. To the right of it is a small box. Step on it and a crate behind
    you will lower. While it's down, get on it (it's where the health potions are).
    
    Once it rises to the top, cross the crates carefully to get to the Red Key.
    Once you have it, drop down to the left and take the teleporter. You'll be
    teleported to the room just after the starting room. Now go all the way
    straight to the door across from you, and open the Red Door to the left. In
    here, open the other Red Door. In this room, go straight and pick up the Yellow
    Key. Now drop down to the pit below you.
    
    Now switch to your Automap. You'll see an opening down in the southwest. Go
    through it, and in here, kill the Former Human Sergeant, collect the health,
    and go
    through the teleporter. You'll be warped to a platform. Kill the Heavy Weapon
    Dude here, hit the switch up here, and go through the teleporter. Now that the
    other half of the bridge has raised, you can cross it to the Yellow Door. Open
    it, and hit the exit switch in here.
    
    ---------------------------
    Level 5: The Waste Tunnels
    ---------------------------
    
    Collect the Shotgun/Super Shotgun in front of you, and go through the opening.
    In here, kill the enemies to the left, and walk up to the door you see. When
    you do, the floor you're on will drop. Down here, kill the Imps in front of
    you. Now go all the way straight to the lift that the Imps were in front of.
    Press the Spacebar to lower it. Take it to the top. When it rises, kill the
    Former Human Sergeants and Former Commandos in here, then open the door in the
    west
    part of this room. In here, kill all the Former Humans, collect the health and
    ammo
    here, and go through the opening in this room.
    
    In here, get the Red Key in front of you, and then go through the opening
    behind you. Kill the Lost Souls here, and then go all the way straight, drop
    down to the ground below you, and go all the way right to the Red Door. In
    kill the Hell Knight (hard skill levels), and climb up the stairs to get to the
    Blue Key. Now before you get to the other Red Door, look for the Green Torch
    here. Walk up to it, press the space bar, go through the small opening to the
    left, and *run* (and I mean run) all the way straight to a dropped floor.
    
    Now get into the secret room before the floor rises again. In here, collect the
    Plasma Gun and hit the switch. The floor will drop again. Now ride it up to the
    top. Back up here, go through an opening and drop to the floor below you. Down
    here, kill the enemies and lower the lift in front of you. Get onto it, and
    when it rises to the top, open the Blue Door in front of you.
    In this room, walk around either path and grab the Yellow Key. Now a bridge
    will rise to the Yellow Door. Go across the bridge, and open the Yellow Door.
    In here, hit the exit switch.
    
    ---------------------
    Level 6: The Crusher
    ---------------------
    
    From your starting point, go all the way straight to an opening across from
    you leading to a lift, killing any Former Human Sergeants/Imps/Revenants in
    your way.
    Now listen very carefully: If you are playing on Skill "I'm Too Young To Die"
    or "Hey, Not Too Rough", go down the lift, through the opening, and then head
    up the stairs to the left of you to get the Blue Key. Get the Plasma Gun here
    too, and watch out for the Hell Knight.
    ------------------------------------------------------------
    If you are playing on Skill "Hurt Me Plenty", stay on the lift and wait until
    it goes back up again. Now you'll notice another opening in the bars
    surrounding the lift. Get in center with it, and *run* past it, hoping to land
    on the platform across from you. Get the Blue Key here.
    ------------------------------------------------------------
    If you are playing on Skills "Ultra Violence" or "Nightmare", get on the same
    platform where you got the Blue Key on "Hurt Me Plenty". On this platform, hit
    the switch, then *run* all the way right to a lowered platform, kill any Imps
    in your way, and get the Blue Key. Watch out for the Spider Mastermind in here
    too.
    ------------------------------------------------------------
    Now, whatever the skill level you played on to get the Blue Key, go to the
    lift you took to get here (go in the slime river, kill the Demons, go through
    the opening down here, take the teleporter, turn around, and go down the
    stairs). Now, look for the part of the bottom of the lift that is not
    surrounded by bars. Walk up to it and press the spacebar, and it will lower
    (the switch next to this lowers the Crusher, which is at the top of the stairs
    behind you, and it can squish the Hell Knights/Spider Mastermind on it). When
    it lowers, get on it, and when it rises to the top, go all the way left, kill
    the Former Human Sergeants and Former Commandos here, collect the ammo and
    health. Now
    open the Blue Door in this room.
    
    Kill the Former Human Sergeant in front of you, and hit the switch to your
    left. The lift
    behind you will lower, and kill any Imps appearing. Get on the lift, and when
    the lift rises to the top, follow the hall to a door (skip the opening you'll
    see on the right), killing any Former Human Sergeants or Imps on the way. When
    you get to
    the door, open it, and then hit the switch to your right. The lift to your left
    will lower, and you can drop down and open the door down here. Do so.
    
    Collect the health in here, then proceed up the stairs, killing any enemies
    in your way. Watch out for the ambushes here, even the one with Revenants. At
    the top, *run* across a small gap to get to another platform. Get the Red Key
    over here. Now the floor you're on will lower, and watch out for the enemies
    beneath you. Kill them, and collect the ammo and health here. Now exit this
    room. Back in here, hit the switch to the left and the lift to your right will
    lower. Get on it, and when it rises, open the door. Back in this hall, go to
    the opening we skipped (not the new one with Imps in it), and go to the Red
    Door. Open it.
    
    In this room, go right, and cross the ledge into a hall. Follow this into the
    other end of the room. Over here, go through the opening across from you,
    killing the enemies in your way. In this opening, open the door. In here, go
    all the way left until you hit a wall, then all the way right until you see the
    Yellow Key on a crate. Hit the switch next to it, and it will lower. Now, get
    the Yellow Key, and go through any teleporter you passed by.
    Up here, kill the Imps/Former Human Sergeants/Hell Knights, and hit the switch
    in this
    room. Now turn around, go through the opening, and when the bridge is finished
    rising, cross it to the Yellow Door. Open it. In here, kill any enemy in front
    of you and hit the exit switch. Now before you start the level you get a little
    story:
    ------------------------------------------------------------
    "You have entered deeply into the infested star port. But something is wrong.
    The monsters have brought their own reality with them, and the star portís
    technology is being subverted by their presence. Ahead, you see an outpost of
    Hell, a Fortified Zone. If you can get past it, you can penetrate into the
    haunted heart of the star base and find the controlling switch which holds the
    Earth's population hostage."
    ------------------------------------------------------------
    
    ---------------------
    Level 7: Dead Simple
    ---------------------
    
    From where you are, hit the switch in front of you. The walls around you will
    lower. You'll see 4/6 Mancubi (plural for Mancubus) in front of you. Use your
    Rocket Launchers, Super Shotgun, and Plasma Gun to kill these. When they're all
    dead, more walls will lower, revealing Arachnotrons. Use a Super Shotgun, a
    Chaingun, a Rocket Launcher, or your Plasma Gun to kill these. When they're all
    dead, stairs will rise to the exit switch in the center of the map. Before you
    exit, hit the switches in this room and the platforms the Mancubi were on
    will lower, revealing health and weapons. Also, from where the Arachnotrons
    came, get the ammo/health from there. Now go back to the center of the map and
    exit.
    
    --------------------------
    Level 8: Tricks and Traps
    --------------------------
    
    NOTE: This level is plentiful of awesome secrets, so I will guide some of the
    good secrets here. If you don't want any of the items, read from paragraph 4
    on.
    
    You start out in a room full of doors. Also, one is Red and one is Yellow. When
    you start the level, open the door to the right of the Yellow Door, and go
    through. In here, get to the other end of the room, and watch out for all the
    Cacodemons. At the end of the room, get the Plasma Gun and the ammo, then hit
    the switch. Once you hit the switch, leave this room, and watch out for the
    Cacodemons. Back in here, open the door to the right of the room you just
    entered, and go through. In here, follow the left hand wall to a Rocket
    Launcher. When you get to the Rocket Launcher, pick it up. Now, turn around.
    
    There should be a staircase rising in front of you, so head up it, killing the
    Demons in your way. At the top there are 2 switches. Hit the one to the left,
    and turn around. See that new opening where the Rocket Launcher was? Go through
    it. In here, pick up the Soul Sphere across from you. When you pick it up, turn
    around, and you'll notice the walls to your left and right have opened. Face
    the wall to the left, and you'll notice a demon head symbol on the wall. Shoot
    it with your Fist, Chainsaw, Pistol, either Shotgun, or Chaingun, and it will
    open, revealing a BFG9000. PICK IT UP! Once you have the BFG, turn left, and go
    back in the room where the Soul Sphere was.
    
    In here, grab all the Backpacks in this room, then leave. Back in here, go all
    the way straight to the staircase across from you (with your back against the
    opening to the "Backpack room"). At the top of the staircase, hit the switch to
    your right. Now, head back down the stairs. Back down here, turn left, and
    leave this room. You'll be back in the level's starting room.
    
    Back in here, open the second door to the left of the Red Door, and go through.
    In here, turn right. You'll see a Cyberdemon facing you but the Barons of Hell
    aren't. Let the Cyberdemon try to attack you, and he will hit the Barons
    instead, so let them all fight. Kill whoever wins the fight (all the Barons or
    the Cyberdemon), and get the Yellow Key in this room (also get the
    Invincibility Sphere and the Soul Sphere), and hit the switch next to the Yellow
    Key. Now, leave this room.
    
    Back out here, open the Yellow Door, and go through. In here, follow the left
    hand wall to the Red Key. When you get to the Red Key, pick it up. Now, turn
    around, and pillars will be lowering, revealing Imps and Barons of Hell. Kill
    them all, and when they're all dead, hit the switch in this room. When you hit
    the switch, leave this room. Back in here, get in front of the Red Door, and
    save your game. Now open it, and go through. In here, use the platforms to get
    to the exit door (if you fall down, re-load your game and start again). When
    you get to the exit door, open it, and go through. In here, hit the exit
    switch.
    
    -----------------
    Level 9: The Pit
    -----------------
    
    Pick up the Combat Armor next to you, and then go and lower the lift that you
    started in front of. When it gets down to the bottom, get on it, and pick up
    the Shotgun. When the lift rises to the top, kill the Former Humans in front of
    you, and go straight, and kill the Imps and Former Human Sergeants up here.
    Also, from
    where the lift was, go straight, and then right, and then hit the switch to
    your right. Now turn around and lower the lift behind you. Get on it, and when
    it rises to the top, hit the switch over here. An opening will reveal, allowing
    you to access ammo and health.
    
    Now from where you are, *run* straight to get to the new bridge that raised.
    From where you are, get on the platform to your left, and go through the
    opening. Kill all the enemies in this room. When they're all dead, drop down in
    the slime pit in the middle of the room, and the floor in front of you should
    lower like a lift. Get on it, and try to find the door here. When you do, open
    it, and the door will lower this time.
    
    In this room, check the walls to your right until a hidden door opens. Kill the
    Lost Soul in front of you and get the BFG9000 (YEESSS!). Now turn around and
    exit this room, and then *run* across the gap to get back on the other area,
    and equip your Super Shotgun. Leave this room too, back into the room where you
    took a lift to get up to.
    
    From the opening you came out of, go right, and enter the first opening to your
    right. Hit the switch in here, and turn around. Now the wall has raised, and
    kill every new appearing enemy, especially that annoying Pain Elemental. Now go
    to where those enemies came from, and hit the switch. A new opening to your
    left has been revealed. From where you are, *run* straight to get to the
    platform next to you. When you land on it, drop down to the floor to the left
    and a platform in front of you should've lowered. Now *run* to it and get the
    Blue Key (kill the Imps on it too). Now go back and get on the silver square on
    the floor. Stairs should rise (don't go up them). Now open the only door in
    this room, and go through. You'll be back here.
    
    In here again, go up the stairs to the left, and go all the way straight and
    you'll be right back here. Now *run* straight to get to the same platform, and
    hit the switch here, and now open the Blue Door over here too. Hit the switch
    in front of you. Now turn back around, jump off this platform, and go up the
    new stairs we created through stepping on the silver square in here, and go
    through the opening. You'll come across a pedestal with 3 switches on it. Hit
    the one on the east part of the pedestal, and a door across from you will open.
    Go through.
    
    In here, drop to the bit below you, and go through the opening to the left.
    Inhere, kill the Imps, collect the health bonuses, and hit the switch in here.
    Now *run* back outside and get on the lowered lift to the left. Kill the
    enemies on this platform, and get the Yellow Key. When you get it, turn around.
    You'll see two openings. One to the left and one to the right. Both lead to
    switches. Go through the opening to the left and hit the switch over there
    first. Now go to the other opening and hit the other switch. Now *run* back
    into the pit, and get on the new lowered platform to the left. Kill the enemies
    on this one, hit the switch on the wall over here, get back in the pit, and get
    on the new lowered platform to the left.
    
    When this platform rises to the top, go through the re-opened opening and back
    into the room with the pedestal. See the wall with health potions in front of
    it (or a wall with no black door on it)? Go up to it and press the spacebar. It
    will open. In this room, open the only door in this room and go through. In
    here, go right towards all the lifts, drop in the pit, and lower the lift to
    the left of where you came from. Ride it to the top. Kill the Former Humans
    here,
    collect the health/ammo, and open the Yellow Door in here. Now follow this hall
    to a pit, ignore the enemies, and jump in. Get the health potions, open the
    exit door, and hit the exit switch.
    
    -------------------------
    Level 10: Refueling Base
    -------------------------
    
    Before you go down the stairs, check the walls up here until a hidden door
    opens. In this room is a Shotgun with a few power-ups. Now go back, down the
    stairs, pick up the Box of Shotgun Shells, and go in the opening across from
    you. Kill all the enemies in here, and go through the opening in this room. In
    this room, open the door on your left, and go through.
    
    In here, go right, kill the Former Humans/Former Human Sergeants in your way,
    and when you
    get to a "4-Way Intersection", go straight until you hit a wall. Over here,
    turn right, and go through the first opening to the right and snatch the Yellow
    Key. Now turn around, go right, and into the opening next to the wall to the
    left. Hit the switch here, and turn around. Go through the new opening.
    
    In this opening, follow this hall to a wall. Press the Spacebar on it, and
    it should open. In here, climb up the little staircase in front of you, and
    when you get to the top, a hidden door should open, revealing the Blue Key. Now
    turn around, go down the stairs, then left, then left again into a bigger room.
    Try to ignore the enemies here, and go through the opening to the right of
    where you came from. Open the door in this opening.
    
    Back in this room, go straight, and then left into the first opening. Follow
    this opening into a bigger room. In here, open the door across from you. Kill
    all the Imps in this dark room, and open the only Yellow Door in this room. In
    this next room, open the Blue Door. In the room above you there's a Cyberdemon
    on skills 4 and 5. Try to ignore it. Now in this room, get to the exit door.
    Open it, and hit the exit switch.
    
    --------------------------
    Level 11: Circle of Death
    --------------------------
    
    Note that this level is called "0 of Destruction!" in the Automap.
    
    Heh, you actually start on a circular platform. Anyways, from where you start,
    head right, and kill any Former Humans/Former Human Sergeants/Commandos in your
    way.
    Go into the first opening you see. In here, kill the Imps, collect the health
    and ammo, and go up the stairs. Up here, kill the Arachnotrons, and go up
    either staircase in here. At the top, kill the Former Humans, and go through the
    opening up here. In this opening is the Blue Key. When you try to get it, an
    Arch-Vile will come out to attack you. If you see fire on you, escape from his
    view so he can't see you, then go back to attack him before he raises the dead.
    
    When he's dead, get the Blue Key, and the Plasma Gun in the same room. Now
    leave this room, go back down either staircase, and back onto the circular
    platform. From where you are, get to the other end of the circle, and open the
    Blue Door. In here, follow this hall to a pedestal. Kill the enemies in front
    of it, and hit the switch on the pedestal. Now go through the other opening in
    this room.
    
    In here, a bridge is rising to another switch. When the bridge is done rising,
    cross it to get to the switch. Kill the Spectres in your way, then hit the
    switch. Now turn around, jump into the slime pit, and get on the floor with the
    Shotgun on it. On here, climb the stairs onto the circular platform. Facing the
    middle of the circle, you'll see a bridge has raised to the Red Key. Get to the
    other end of the circle, cross the bridge, kill any un-killed enemies, and get
    the Red Key. Now turn around, cross the bridge onto the circle, jump into the
    slime pit, go all the way left, then right, to the Red Door. Open it, and go
    through.
    
    Kill the Former Human Sergeants in your way, then head right, towards a set of
    bars.
    Walkup to them and they will be removed. Kill the Lost Souls here, and head up
    the stairs to the left. Follow them to a pole with a switch on it. Hit it, and
    kill the enemies around you. Now that the barriers are lowering, *run* to the
    new path you can now access. Follow it to another room.
    
    In here, try to ignore the Cacodemons, and go through the opening at the other
    end of the room. In this opening, drop down to the floor below you. In here,
    kill the Former Human Sergeant, go left, turn left again, and lower the lift
    over here.
    Get on it, and when it rises to the top, collect the health here, kill the Imp,
    and hit the switch. Now go back down the lift, and back here again, go all the
    way right, and then turn right again to this lowered lift. Once it rises to the
    top, hit the switch up here, kill the Imp, and drop down back here. Now turn
    left, and go through the opening to the right. Go straight and hit the exit
    switch. Now, before you can get to the next level, you get another story:
    ------------------------------------------------------------
    "You have won! Your victory has enabled humankind to evacuate Earth and escape
    the nightmare. Now you are the only human left on the face of the planet.
    Cannibal Mutations, Carnivorous Aliens, and Evil Spirits are your only
    neighbors. You sit back and wait for death, content that you have saved your
    species. But then, Earth Control beams down a message from space: "Sensors have
    located the source of the Alien invasion. If you go there, you may be able to
    block their entry. The Alien base is in the heart of your own home city, not
    far from the star port." Slowly and painfully you get up from the Fray."
    ------------------------------------------------------------
    
    ----------------------
    Level 12: The Factory
    ----------------------
    
    From your starting point, go all the way right until you hit a wall. From
    here, go all the way left until you hit a wall. Facing the wall you just hit,
    turn around and go up the staircase. At the top, go straight until you see a
    door to your right, and kill any Arachnotrons in your way. When you get to the
    door, open it (the door will lower instead), and then jump into the pit below
    you. Down here, go straight until you get to the center of the room, and then
    go right, through the opening.
    
    In this hall, go right and get the Blue Key. Either kill or escape the
    Arachnotron above you. When you get the Blue Key, turn around and get to the
    other end of the hall. Over here, open the door to your left. Kill the enemy
    in front of you, and get the Yellow Key. Now, leave this room, and from here,
    go all the way right (skip the first opening), and enter the second opening to
    the right.
    
    Over here again, turn left and open the Blue Door. In here, go straight, and
    the floor you're on will lower. Kill the Former Human Sergeants down here,
    collect their
    Shotguns, collect the health, and take the teleporter. You'll be teleported
    outside. Kill the enemies around you, and before you jump off the platform
    you're on, look for two green torches next to each other around you. When you
    see them, jump off the platform, and go to them.
    
    The Yellow Door is in between those torches. Open it. In here, collect the
    Berserk Pack, and open the door across from you. There are lots of elevators in
    here, and each one contains a Cacodemon, and 5 of them have switches you need
    to hit in order to exit. Kill the Cacodemons, look for the 5 switches in the
    lifts, and hit each one you see. When you hit all five of them, an opening next
    to the door you took to get in this room will be accessible. Go through it, and
    take the exit teleporter you'll meet up to.
    
    -------------------
    Level 13: Downtown
    -------------------
    
    From where you are, go all the way straight until you see a set of teleporters.
    Take anyone (you'll be warped to the same place). When you teleport up here,
    turn left, and *run* to get to the area across from you (kill the Cacodemons in
    your way first if you have to). When you get on this platform, open the door
    here. In this room, you'll see a teleporter. Don't go in it. Instead, go down
    the stairs to the right.
    
    Down here, you'll see two doors. Open the door on the left. In here, follow the
    hall to a brown wall, and kill any enemies in your way. When you walk up to the
    wall, exit this room. Now go left. The other door has opened. Get the Blue
    Key and take the teleporter right here. You'll be warped back to the starting
    point.
    
    Back here, go all the way straight again and take the same set of teleporters.
    Up here again, turn around, and *run* straight to get to the platform across
    from you. Kill the Revenants here, and open the Blue Door. In this room, jump
    down to the left, and take the teleported. You'll be warped right next to the
    Red Key. Pick it up, and kill the Imps and Demons around you.
    
    Now jump off the platform you're on, and go all the way straight back to the
    starting point of this level. Just where you started there's an opening to the
    left. Go through it, and over here, open the Red Door at the building. In here,
    kill the Imps and Spectres you see, and walk up to the lift in front of you.
    Wait for it to lower. When it reaches the bottom, get on it, kill the Imps on
    it, and wait for the lift to reach its highest.
    
    When it gets to the top, face the door you entered to get here, and look right.
    You'll see the Yellow Key on the platform. Now *run* straight and get it. When
    you have the Yellow Key, leave this room. Back out here, go right until you hit
    a wall, and then look left, and go through the opening to the right. Go through
    this hallway.
    
    When you get to the end of hit go left until you see an opening to the right.
    Go through it and get to the Yellow Door in the opening in the left. Kill any
    Arachnotrons/Cacodemons you might see. Open the Yellow Door. In here get the
    Berserk Pack, and step in the lava in the middle (it's the exit).
    
    --------------------------
    Level 14: The Inmost Dens
    --------------------------
    
    From your starting point, go right, and go right again, down the stairs. Down
    here, go all the way straight, then left, killing any Former Human Sergeants in
    your
    way. Over here you'll see a door. Walk up to it and it will open. Kill the
    enemy you'll see when it opens. Now walk up straight to the next door, and this
    door will open. In here, go right, and then left, and left again up the stairs.
    
    Up here, open the door in front of you. In here, go straight, towards the wide
    opening. Get in center with it, back up, and *run* through the opening to get
    to a platform across from you. When you get on the platform, go straight into
    another room, and in here, follow the hall to the left to the Red Key and a
    Plasma Gun, killing any Imps, Former Humans, Former Human Sergeants, or Former
    Commandos in
    your way.
    
    Once you have the Red Key, turn around, go back into the opening we used to get
    in this room, cross this platform again, and then *run* to get to the area
    across from you. Over here, go right, then left, towards the same doors we used
    to get here, and walk up to both doors again to have them open. In here, go
    left, then right, and get to the Red Door next to the Red Bars. Open the Red
    Door, hit the switch inside, and it will lower the Red Bars.
    
    Now, get to where the Red Bars were, and walk up to this door, and it will
    open. In this room, walk up to this door, and it will open. In here, kill the
    Former Humans and Former Human Sergeants, and that Arch-Vile on Ultra Violence
    (and also kill
    the Former Commandos in the cages). When all the enemies are gone, open the
    door in this room.
    
    Kill the Former Humans, Former Human Sergeants, Imps, and Former Commandos in
    this room,
    walk up the stairs, and go right and pick up the Blue Key. When you do, leave
    this room, go straight, walk up to the door across from you to make it open, do
    the same to open the door in this room, and then in this room again, go right,
    then left, and right again to the door, walk up to it to open it, do the same
    to open the door in here.
    
    In this room again, go right, then left, then left again up the stairs, open
    the door, go straight, *run* through the opening across from you to get on a
    different platform, and then cross the platform into here again. This time, go
    right, and follow the hall to an opening.
    
    Facing the opening, *run* straight to get on the next platform. Go through the
    opening here, then go right, and then left. Over here, kill the Former Human
    Sergeants,
    and over here, one of the openings connects to a bridge. Go through the
    opening, across the bridge, and open the Blue Door across from you.
    
    In this room, kill the Former Commando, go down the stairs, and get in center
    with the opening across from you. Now *run* through the opening to get to the
    door that you can see. When you get to the door, open it. In this room, hit
    the exit switch.
    
    ------------------------------
    Level 15: The Industrial Zone
    ------------------------------
    
    At the start, open the door to the left. In here, collect the Shotgun and the
    Box of Shotgun Shells. Now hit the switch in here to lower the lift you're on.
    Down here, go through the opening. Out here, go right, and then left through an
    opening, killing any Former Humans or Former Human Sergeants you'll see. Now go
    straight
    until you hit a wall. Now go right, and then left. From here, go all the way
    straight to a huge gap, and fall in. Down here, follow the left wall to a
    teleporter. Take it.
    
    When you teleport, pick up the BFG in front of you, walk forward, and the wall
    will open, revealing a Baron. Kill it with the BFG. Now walk up to the wall the
    Baron was in front of, and it should open, revealing a Pain Elemental and the
    Yellow Key. Kill the Pain Elemental, get the health and the Key. Now turn
    around and you'll see a pedestal with a switch. Hit it, and stairs in front of
    you will rise to a platform. Climb the stairs to the top, and kill any new
    Cacodemons or Pain Elementals.
    
    Up here, go left, and follow the left wall to a yellow torch. From here, follow
    the left wall to another torch. Now, save your game, and look at this map:
    
          |    |
          |    |
          |              Lava
    ______|                 _____
    TX                     |  P  |
                            -----
    ____________
    
    Say the T is the torch, the X is you, and the P is a platform with a switch on
    a pedestal. From where you are, save your game, go straight, and jump off the
    platform you're on, and pray for the best to land on the "P" platform. You can
    try running too, but if you do, let go of Shift as you fall. If you fail to get
    on, reload your saved game.
    
    When you get on the platform, hit the switch on the pedestal, collect the
    Energy Cell Packs, and the Radiation Suit. Facing the switch, drop down into
    the pit, and go all the way straight to an opening. Follow it to a bigger room.
    Kill the Cacodemons in here, and get the Invincibility Sphere. Now leave
    this room and go back into the bigger slime pit.
    
    Out here, go all the way straight back into the same teleporter. Take it. From
    where you are, turn around, go back up the stairs. At the top again, look
    straight. You'll see an area all by itself with the Yellow Door. Here's a map:
    
       ______________________
               |              \
               |  <--Yellow   |

       ________|______________|
    
    
          Lava

                      |---------|
                      |---------|
    
    Say the X is you. From the top of the stairs, back up, and *run* straight
    across the lava pit to get to the area with the Yellow Door. When you get on
    that land, kill the Former Humans and Former Human Sergeants, and open the
    Yellow Door.
    
    In here, go in the opening way across from you. In here, follow the hall until
    you see an opening to the left. Go through it, and follow it to the exit
    teleporter (this takes you to the secret exit ;)). Before you start the secret
    level you get a message.
    ------------------------------------------------------------
    Congratulations, you've found the secret level! Looks like it's been built by
    humans, rather than Demons. You wonder who the inmates of this corner of Hell
    will be.
    ------------------------------------------------------------
    
    ----------------------
    Level 31: Wolfenstein
    ----------------------
    
    Ok, if you have the German version of Doom II, don't bother reading this or the
    next level (anything that has Nazi symbols in it are forbidden by law in
    Germany, and when you try to enter this level in the German version, it will
    just take you to Level 16). Anyway, this is a replica of the very first level
    in Wolfenstein 3D.
    
    Anyway, open the door in front of you at the start. In here, open the door at
    the far left. Kill the Nazis (WolfSS) in here, pick up their ammo, and open the
    other door. In here, kill the Nazis, and go through the door across from you.
    In here, kill the Nazis across from you, and go in the opening to the left.
    
    In this little alcove, kill any Nazis, and walk up to the picture. Press the
    Spacebar on it, and it will open. In here, get the ammo, the health, and the
    Rocket Launcher. Now leave this room, and back in here, open the door at the
    left.
    
    In this room, kill the Nazis, and open the door on the left. In here, go
    straight, and then left. Kill the Nazis over here, and also open the door over
    here. In this room, kill the Nazis, and also open the door on the left from
    where you came from. Now, in this empty room, open the door across from you.
    
    Now, in here, kill all the Nazis, and open the door across from the door you
    came from. In this room, go straight, then left, and then open the door,
    killing any Nazis in your way. In here, kill the Nazis. Now, from where you
    entered, check the walls to the right until a hidden door opens. In here,
    collect the Medikit, and check the walls in here too until a hidden door opens.
    
    Now, go straight and you'll find another exit door. Before you open it check
    the walls to the left until a hidden door opens. In here is a Soul Sphere. Grab
    it, and now open the exit door. Hit the switch in here (this takes you to
    another secret exit ;)). Now, before you start the next level, you get another
    story:
    ------------------------------------------------------------
    Congratulations, you found the Super Secret Level! You better blaze through
    this one!
    ------------------------------------------------------------
    
    -----------------
    Level 32: Grosse
    -----------------
    
    Collect the Rocket Launcher, the Berserk, and open the door in front of you at
    your starting point. Here's another familiar level: The last level of Episode 1
    in Wolfenstein 3D. Anyway, kill the Nazis here, and you'll obviously see
    rectangular pillars. 4 of them are secrets. Here's which pillars to check:

          |                      |
          |     Starting Room    |
    
    Say the X is you. There are 10 pillars in this room. Check the pillars that
    have numbers on them. 1 has 3 Chainguns, 2 has a Megasphere, 3 has a Super
    Shotgun with 2 Boxes of Shotgun Shells, and 4 has a BFG. Also, to the both
    sides of this room, you'll see gold Nazi Plates. Walk up to each and press the
    Spacebar. Two of them will open (remember to check both sides of this room).
    
    Once you find the two Plates that open, you'll see that one of them shows an
    Invincibility Sphere, and the other leads to another room with loads of
    Medikits, Energy Cells, and a Plasma Gun. When you're done collecting all this,
    go back into the room with the 10 pillars, and walk up to the door we haven't
    opened yet. It will open, revealing a Cyberdemon.
    
    Do whatever you can to kill it (use Rocket Launcher and BFG, and the
    Invincibility Sphere can help), and when it's dead, go into the room it came
    out of, and open the door in here. In this room you'll see 4 Commander Keens.
    Kill each one, and a silver wall will open in the center of the room, revealing
    an exit switch. Now, from the floor, *run* to get up onto the platform. Up
    here, hit the exit switch.
    
    ------------------
    Level 16: Suburbs
    ------------------
    
    At the start, go straight, and open the door. Out here, go left, and you'll
    come across an opening. Go through it. In here, go right, and then right again.
    Over here, go all the way straight until you hit the wall way across from you.
    When you touch the wall, go all the way right, into the slime pit across from
    you. In the slime pit, head up the spiral stairs, killing any Imps in your way.
    Follow it to a Blue Key.
    
    When you have the Blue Key, jump off the platform you're on, and *run* (and I
    mean run) all the way straight before you're caught in a major enemy jam. Over
    here, keep going straight until you see an opening to the right. Go through,
    and you'll come across stairs to your left. Go up them, and kill any Revenants
    you might see.
    
    At the top of the stairs, go through the opening across from you. In this room,
    kill all of the Demons, and open the only door in this room. In this room, go
    straight, and open the Blue Door, and kill any enemies in your way. In this
    room, collect the Shotgun Ammo and get the Red Key, then leave this room.
    
    Back in here again, go right and open the same door you did to get here. In
    this room, jump off the ledge across from you and go straight, to all of those
    black and white platforms. Down here, walk up to the highest one on the ground,
    and press the spacebar on it. It will lower, and when it's at the bottom, get
    on it. When it rises to the top, jump down to either pit below you.
    
    When you hit the ground again in either of the two small pits, check each
    pillar around you. One of them will lower. When it's finished lowering, get on
    it, and ride it to the top. When it's at the top, drop down to the ground
    slightly below you. When you land, press the spacebar on the same pillar you
    just took to get here.
    
    When you do, the pillar will lower. Now turn around. The wall has lowered too.
    Kill all the Imps here, and go into the new room. If the wall raises again,
    just lower the pillar and turn around again. When all of the Imps are dead,
    get into the room they came from, and press the Spacebar in front of the Red
    Bar. It will open, allowing you to get to the exit teleporter. Now, step on the
    exit teleporter, and you're out of this level.
    
    --------------------
    Level 17: Tenements
    --------------------
    
    Collect the Shotgun Shells in front of you, and go straight. In this room, kill
    all of the Former Human Sergeants and Former Humans, and go through the only
    opening in this
    room (besides the one from the starting room). In this room, walk carefully
    down the stairs to the health and the Red Key. Kill the Imps in front of you
    too (and any Cacodemons). If the opening you entered to get here shuts down,
    don't panic. Facing the shut down opening, drop in the pit to the left, and go
    straight. You'll see part of a teleporter next to the wall across from you.
    Take it.
    
    You'll be warped to the right of the opening you took to get to the Red Key. Go
    up the stairs to the left of you, and open the Red Door. Kill the Spectres in
    here, collect all of the ammo and health in this room, and hit the switch.
    Now leave this room. Out here, go up the stairs across from you.
    
    Up here, collect the Shotgun, ammo, and health, and hit the switch in this room
    (it lowers a lift you're on). Down here, kill the Spectres, collect the health,
    and kill the Hell Knight you might see. Go on the ledge across from you.
    Follow it to a switch. Hit it, and a lift near you will lower. Ride it to the
    top. Up here, kill the Imps, and hit the switch up here (the green/red one).
    When you hit that switch, hit the other switch in this room (it's a door). Drop
    down back into the starting room.
    
    Back down here, go through the opening to your right. In here, go through the
    new opening across from you. In here, go through the opening to the right, and
    up the stairs. Up here, kill the Imps/Former Human Sergeants/Former Commandos.
    Go all
    the way straight, and over here, go through the opening to the left, and drop
    in the pit below (kill any Former Human Sergeants in your way). Down here, hit
    the switch
    to lower the platform in front of you.
    
    When it's done lowering, go straight and hit the new visible switch. Now, wait
    until the platform you're on rises again. When it reaches the top, go straight,
    kill the Former Human Sergeants in front of you, and go through the new opening
    to the
    left. Kill the Spectre in front of you, and go up the stairs. Up here, hit the
    switch, collect the ammo and armor, and go through the opening up here. Drop
    down to the room below you.
    
    Down here again, go straight to the newly raised bridge. Follow it to a gap.
    Drop down in hit. Hit the switch down here, and the floor will rise to the
    other platforms (and a new bridge will rise at the other side of the room). So,
    when this platform rises to the top, get to the other end of the room, and
    cross the new bridge.
    
    Kill any Cacodemons/Revenants over here, collect the health and the Blue Key,
    and exit this room (back outside). Out here, go all the way straight to the
    Blue Door. In here, kill the Former Human Sergeants and Imps in front of you.
    Also in
    this room, go up the staircase to the left. Up here, kill the Heavy Weapon
    Dude and the Former Humans, and then walk forward and you'll hear the sound of a
    door open.
    
    Go back down stairs and go through the new opening across from you. Grab the
    Soul Sphere in here, and go back up the same stairs. A pedestal with a switch
    up here has been raised. Hit the switch, go back down the stairs, go right, and
    go up the stairs over here. Up here, kill the Former Commando, and go through
    the opening to your left.
    
    In here, go left. Kill the enemies in front of you, and then follow this
    hallway to an opening to the left. Go through it, and drop down into the pit
    below you. Walk forward to the lift across from you, and it will lower. Get on
    it and get the Rocket Launcher and the Yellow Key. Kill any remaining enemies
    on this platform too.
    
    When the lift rises back to the top again, jump off the platform you're on and
    exit this room. In here, go left to the Yellow Bars. Facing the Yellow Bars,
    turn around and open the Yellow Door. In here, flip the switch, and turn
    around, and you'll see the bars have lowered. Now go into this new
    accessible room.
    
    In this room, go straight into another opening. Grab the Shotgun Ammo just
    before it. Once you go through this opening, you'll see two staircases. Take
    the left staircase. Follow it to another room. In this room, go in the opening
    to your right, and open the door.
    
    In here, kill the Former Commandos you see. When they're dead, equip your
    BFG. As you walk up the stairs you'll see an Arch-Vile in a cage. Use your BFG
    to kill it. Now go all the way up the stairs. At the top you'll get to a
    switch. Hit it, and get back to the door you used to get to this room. Open it.
    
    Back in this room, drop down to the floor below you, and go in the opening to
    the left. This time, go up the staircase to the right. At the top, go straight,
    and into the opening to the left. Kill any Former Human Sergeants/Imps/Former
    Commandos
    you might see. In this room, hit the switch. The lift to the right of you will
    lower. Take it. Ride it to the top.
    
    When the lift gets to the top, kill the Arachnotron you might see (skill level
    varies), and pick up the Plasma Gun across from you. An opening to the left of
    you will open. Go in it, and kill the Imp. Walk up to the health potions here,
    and you'll here another door open. Leave this little room, and back out here,
    go through the new opening to the left.
    
    In here, kill the Former Human Sergeant, and walk up to the armor bonuses.
    You'll hear
    another door open. Leave this hall, and go back into the same opening to the
    right. Now, in this same hall, follow it to another Imp. Kill it, and walk up
    to the Energy Cell. You'll hear another door open. Leave this hall.
    
    Back out here, go in the same opening to the left. Now follow it to a Shotgun
    Guy. Kill it. When it's dead, walk up to the Energy Cell Pack, and you'll hear
    ANOTHER door open. Leave this hall. Back out here, turn right. You'll see a new
    opening this time. Go in it. In here, kill the enemy in front of you, and
    follow the hall to the health potions. Walk up to them, and you'll hear another
    door open. Leave this hall.
    
    Back out here, go through the opening to the left. Follow it to another Shotgun
    Guy. Kill it, and when it's dead, follow this hall to an Energy Cell. You'll
    hear another door open. Leave this hall. Back out here, go through the opening
    to the right. Follow it to a new room. Kill the Former Commandos in here, and
    take the exit teleporter.

    Level 18: The Courtyard
    ------------------------
    
    See the door in front of you? Take a Pistol, either Shotgun, or a Chaingun.
    Shoot the door to open it (you can also use your Fist or Chainsaw to open it).
    Out here, kill the Former Human in front of you, and kill all the other Imps in
    this room too. In here, collect all the Shotgun Ammo, and the Shotgun, and go
    through the only opening in this room (into the courtyard). When you get into
    the courtyard, *run* all the way straight to the staircase across from you
    (don't climb it). Facing the staircase, go through the opening to the left of
    it. Over here, collect the Yellow Key. Now go back and up the stairs (before
    the Demons trap you), and up here, go all the way right, then left, and left
    again to the Yellow Door. Open it.
    
    In here, take the teleporter before the Cacodemons come and get you. When you
    teleport into this room, kill the Cacodemons in front of you. Now drop down to
    the floor below you. Down here are loads of health potions. The Blue Key is
    scattered down here to. Pick it up. Also down here are a few pillars. One of
    them has a switch. Hit it, and to the left of you a staircase has risen to a
    teleporter. Take it.
    
    You'll be teleported in the Yellow Door room. Now go right, down into the
    floor below you, and *run* all the way straight to the opening across from you,
    before you get caught in a huge enemy mess. Back in this same room, go right,
    through the opening, and back into the starting room. In here, open the Blue
    Door. Take the teleporter in this room.
    
    ----------------------
    Level 19: The Citadel
    ----------------------
    
    At the start, open the door in front of you. In here, kill the Former Human
    Sergeants,
    and hit the switch to the right (it is a door). In here, kill the Imps, and hit
    the switch in this room. Now leave this room, and in here, open the door to the
    right. Out here, go straight and open the door across from you.
    
    In here, kill the Lost Souls, get the armor and ammo here, and from where you
    entered this room, head up the staircase to the left. Up here, open the door to
    your left. In here, go straight and hit the switch on the pedestal across from
    you. When you hit the switch, a door across from you will open. Go through.
    
    In here, walk up to the door across from you (touch it). When you touch it, you
    should hear another door open. Turn around and leave this room (if the door
    closes on you, turn around and open the door we walked up to, kill the Imps in
    here, and hit the switch to the right, the door will open again). Back in here,
    go through the new opening to the left (if this one shuts, walk up to the same
    door again <_>).
    
    Kill the Imps in this hall. Now follow this hallway to a wall. It will lower.
    Kill the Imps and Spectres in front of you, and when they're dead, go through
    the only other opening in here. Follow it to the Yellow Key. When you pick it
    up, turn around, go straight, and drop down to the floor below you.
    
    Down here again, hit the switch on the pedestal, and turn around (it opens up
    another door too). Now go through the new opening. In this room, go through the
    opening to the right, and open the door. In this room, walk up to the
    Soul Sphere. When you walk up to it, you will teleport (and you don't get the
    Soul Sphere :().
    
    When you teleport, there will be an Imp cage to the left and right of you. Pull
    out your Pistol, either Shotgun or a Chaingun and shoot the Imp cage to the
    left of you (kill the Imps too, and do this with the other Imp cage). Once you
    shoot the Imp cage to the left, a platform will rise to the door across from
    you in this room (you can see it when you first teleport here).
    
    Once the platform is finished rising to the door, cross the platform and open
    the door. In here, follow this hallway to another room, killing any Cacodemons
    in your way. Down here in this room, kill the Arachnotron, and grab the Red
    Key. Once you have the key, drop down into the floor below you, and down here,
    go all the way left and open the only door in this room.
    
    Back in here, open the door to the right. In this same room, hit the switch on
    the pedestal. Now, the two doors will open again. Go through the opening behind
    you again. In here, go straight until you see an opening to the left (skip the
    first one that's right next to you when you enter this room). Facing the
    opening, check the walls to the left of it until a hidden door opens.
    
    When you find the hidden door, go in the room, and pick up the Armor. When you
    get the armor, check the wall in front of you. It should lower (it's a lift).
    When it's done lowering, get on it. Now ride it to the top. Up here, follow
    this hallway to an opening.
    
    Before you go through it, get in center with it, back up, and then *run*
    straight. Hopefully when you land, you should land on the ledge a little higher
    than the floor you just ran over. If you land on the ledge, drop down into the
    water not the floor. Down in the water, head up the stairs. Up here, there are
    two openings. Take the one on the corner.
    
    In here, follow this hallway to a bigger room, and watch out for the crushing
    ceiling you'll pass. In this bigger room, head up the only staircase in this
    room. At the top, hit the switch on the pedestal, then leave this room, going
    back down the stairs. Down here again, go left, through the opening.
    
    In this hall, go straight, and drop down to the floor below you. You can see 5
    teleporters. Take the one in the northeast part of this room. When you
    teleport, go straight, and drop down into the room below you. Down here, use a
    BFG or a Super Shotgun to kill all of the Demons in this room. When all of the
    Demons are dead, go through the opening to the left of the staircase in this
    room, and drop down to a lower floor.
    
    Down here, pick up the Blue Key. Once you pick it up, drop down to the floor
    below you, and go all the way straight, and open the door over here. In here,
    go straight, and open the door. Out here, go left, and follow this pathway to a
    staircase leading to the building (you'll see it to the right of the staircase)
    killing any Spectres in your way.
    
    Once you get to the stairs leading to a building, cross the stairs to the
    building. Over here, take either opening to the other side of this room. Over
    here is an opening blocked by a Red Bar, a Yellow Bar, and a Blue Bar. Press
    the Spacebar on each of them to remove them, go through the opening, and step
    on the exit teleporter.
    
    ------------------
    Level 20: Gotcha!
    ------------------
    
    Kill the Former Human Sergeant right in front of you, and open the door he was
    in front
    of. In this room, kill the Former Human Sergeants, Imps, and Former Commandos.
    Then,
    walk straight. Two wide and large pillars will lower. One contains the
    Cyberdemon, and the other one has a Spider Mastermind. When you see both of
    them, when you they try to attack you, try to make sure the Cyberdemon's
    Rockets hits the Spider Mastermind, and vice versa.
    
    When this happens, the Spider Mastermind and the Cyberdemon will start fighting
    to the finish. The Cyberdemon is stronger, so he usually wins. Once the two are
    fighting, have a seat, relax, and watch the fight. Whoever wins the right, use
    your Rocket Launcher or a BFG to finish off the remaining enemy.
    
    When both of them are dead, drop down into the pit below you, and down here, go
    up the only staircase in this pit. It will lead you to the pillars the
    Cyberdemon and the Spider Mastermind were on. At the top, go straight, get on
    the Spider Mastermind's pillar and hit the switch on the pedestal.
    
    Once you hit the switch, drop down to the left, and lower the lift down here.
    Get on it once it hits the ground. Now ride it to the top. Once you're at the
    top, take either pathway to the other side of the room, and once you get to the
    other end of the room, kill the Arch-Vile and the Baron of Hell over here, and
    go through the opening.
    
    In this room, go straight, and then take either staircase. Both lead the same
    way, and at the bottom of either staircase you take, go straight, and step on
    the Demon Head symbol on the floor. It will teleport you. When you teleport,
    go down the stairs in front of you. You'll see an opening across from you, and
    you have to also cross the gap in front of you.
    
    So, get in center with the opening, back up a little, and then *run* across the
    gap to get through the opening. In here, kill the Pain Elemental in front of
    you, and when it's gone (and the Lost Souls released from its explosion),
    follow this hall to a wall. It will open, revealing a teleporter and a few
    Weapon Dudes. Kill them, collect their Chainguns, and take the teleporter.
    
    Once you teleport, the floor you're on will lower. When it hits the ground,
    kill the Former Human Sergeants and Former Commandos in front of you. Now walk
    forward
    to the opening, go through, and collect the Medikit. Now don't jump off the gap
    yet. Now the wall in front of you will lower. Now don't jump off until the wall
    completely lowers (you'll here a "cling" sound).
    
    Once the wall completely lowers, jump down, and go through the small opening
    in front of you. In here, follow this hall to a stairway. Go up the stairs and
    kill the Imps in front of you. At the top, pick up the Plasma Gun. Now, the
    wall will open behind you with a few Cacodemons and Pain Elementals. To avoid
    trouble, drop down to the floor to the right (instead of using the stairs), go
    straight into the hall we used to get to this room.
    
    Now in this hall, go through the new opening to the left. In here, take the
    teleporter. When you teleport, kill the Imps, Cacodemons, Pain Elementals, and
    the Lost souls in here (use a BFG, it can do the job;)). When they're dead, go
    up the staircase, get across the zig-zag floor, and go through the exit
    teleporter, avoiding the Revenants. Now before you go to the next level, you
    get a little story:
    ------------------------------------------------------------
    You are at the corrupt heart of the city, surrounded by the corpses of your
    enemies. You see no way to destroy the creatures' entryway on this side, so you
    clench your teeth and plunge through it. There must be a way to close it on the
    other side. What do you care if you've got to go through Hell to get to it?
    ------------------------------------------------------------
    
    ------------------
    Level 21: Nirvana
    ------------------
    
    Pick up the Super Shotgun and the health around you, and kill the Imps in here.
    When they're dead, look around the room. You'll see two teleporters on
    platforms. Standing on the floor you started out on, *run* to the teleporter
    next to the platform with a human hanging above it.
    
    When you teleport, follow this hall to an opening. Out here, take either path
    to a teleporter at the other end of the room, and kill those Former Human
    Sergeants too.
    When you get to the teleporter, go through it, and ignore the wall that opens
    (enemies are inside), for when you walk up to it.
    
    When you teleport, look right. You'll see a pedestal with 4 switches on it (2
    are on another side). Hit all 4 of them, and then you'll see parts of the wall
    rise in front of you. Walk up to the wall that raised, and press the Spacebar
    to lower it. When it gets to the ground, get on it, and it will rise to the top
    again.
    
    Up here, go straight until you get to two teleporters. Take the one on the
    right, and ignore the Imps and the Mancubi. When you teleport, walk up to
    the wall in front of you, and press the Spacebar. The wall will lower, and when
    it
    lowers, kill all of the Imps around you. When all of the Imps are dead, walk up
    any part of the floor around you, and it will lower (or if you already did so).
    
    Once the wall is finished lowering, kill the Pain Elementals around you, and
    once they and their Lost Souls are all gone, check around this room. At one of
    the corners is the Yellow Key. Pick it up. Now another one of the corners of
    this room has a teleporter. Go through it.
    
    You'll be teleported on the teleporter you used to get to the Yellow Key room.
    Back here, go all the way right, jump off the floor you're on down into the
    lower floor, and down here, take the teleporter. Back in this room, avoid the
    new appearing Revenants, and go through the opening in the center of this room.
    Back in this hall, go through the teleporter.
    
    You'll be back in the starting room. In here, collect the health you may need,
    get on the floor the health is on (or where you started the level on), and
    *run* to the other teleporter you didn't take yet. In this room, remove the
    Yellow Bar to your right.
    
    Once you remove it, follow this pathway to a wall. Once you hit the wall, turn
    left and kill all of the Imps on the platform to you left. When they're dead,
    turn around, pull out a Rocket Launcher, Plasma Gun, or a BFG, and kill all of
    the Former Commandos on the other platform.
    
    When all of the Former Commandos are dead, get center with the platform the
    Imps were on, and then *run* to get on the platform. On this platform, hit the
    switch, turn left, and *run* to the lowered platform the Former Commandos
    were on. Now get on the platform, and collect the Red Key.
    
    Once you got the Red Key, jump off the platform to the left (if your back is
    at the edge of this platform), and go through the small opening here, and *run*
    too, because this floor is toxic. Now follow this small hall to another part of
    the room.
    
    At this half of the room, go left, and lower the platform the Imps are on. Kill
    the Imps on this platform, and get on it while it's at the ground. When the
    platform rises back to the top, get in center with the pathway right in front
    of you, and *run* across this gap to get on it.
    
    Back on this pathway, go left and you'll come up to 2 Blue Bars. You'll also
    notice an opening you can just fit through in between the Bars. So go through
    the opening and you'll get to the Red Bars. Remove either one of the 2 Bars,
    and go through the teleporter you can now access.
    
    In this room, walk straight to the exit teleporter.
    
    ------------------------
    Level 22: The Catacombs
    ------------------------
    
    From where you are, check the walls to your left and a hidden door should open.
    Kill the Spectre in front of you, and collect the Soul Sphere, Armor, and Ammo
    in here. Now leave this room. In here, go straight and lower the lift in front
    of you. When it gets down to the bottom kill the Demon, get on it, and ride it
    to the top. Once it gets to the top, kill the Former Commandos on the
    platform in front of you (and the Spectres below if you need to). When the
    Former Commandos are gone, get in center with the platform they are on, and
    *run* across the gap to get to the platform.
    
    On this platform, with your back facing the lift you took to get here, go left,
    jump in the gap below you, and down here, lower the lift right next to
    you. Get on it, and ride it to the top. Up here, kill the Spectres and Imps in
    front of you, and when they're all gone, drop down in the pit below you. Down
    here, go up the stairs, and up here, follow this hall until you see an opening
    to your right, and kill any Imps and Former Commandos in your way.
    
    Once you see the opening to the right, go through it, and turn left. In here,
    go straight until you see a door to your left. Open it. In here, kill the Imp
    in front of you, and take the teleporter. When you teleport, kill the Revenant
    in front of you, and pick up the Blue Key in front of you. Once you have it,
    walk onto the ledge the Blue Key was in front of (it leads to the platform). On
    this ledge, get in center with the platform in front of you, and *run* straight
    to get onto it.
    
    On this platform (again), with your back facing the ledge we just used to get
    here, go right and drop down into the pit below you. Down here, lower the lift
    next to you (it does drop down to a lower ground). Now, drop down along with
    the lift and down here, kill the Demons in front of you. Also down here, open
    the Blue Door, and hit the switch in front of you. Now exit this room.
    
    Back out here, facing the Blue Door, go right, and go through the opening in
    front of you. Follow it to an opening to your left. Go through the opening, and
    drop down to the ground below you. Down here, kill the Imps, and hit the switch
    down here. When you hit the switch, a door to your right has opening. When it
    opens, kill the Baron of Hell in front of you, and go into the room he came out
    of.
    
    In here, hit the switch to your left, and leave this room (if the door shuts on
    you hit the other switch to open). Back out here, *run* straight to the
    lowered platform, and get on it. Ride it to the top. Up here, go through the
    opening, and in here, get the Red Key. Also in here, press the Spacebar on that
    Demon head on that wall, and it will open. Take the teleporter in front of you.
    
    In this room, pick up the Plasma Gun in front of you, and take the only
    teleporter in this room. When you teleport, go straight, into the gap in front
    of you, and lower the lift near you too. Get on it, and ride it to the top. Up
    here, kill the Revenant, and open the Red Door in this room. In here, kill the
    Former Commandos in front of you, and open the Exit Door in this room. In
    here, kill the Former Commandos in front of you, go straight, and hit the
    exit switch.
    
    -------------------------
    Level 23: Barrels O' Fun
    -------------------------
    
    The level name describes it all. Without moving when you enter this level, blow
    up at least one of the barrels surrounding you (blow up one that's not right
    next to you to lower your chance of being killed). It will blow up, and all of
    the other barrels will blow up too. When all of the barrels are gone, get to
    the other end of the room and open the door. In here, go through the
    teleporter.
    In this room, go all the way straight to the other end of the room, without
    blowing up any Barrels or trying to kill any Hell Knights or Heavy Weapon
    Dudes. At the other end of the room, take the teleporter. In this room, walk
    all the way straight to the other end of the room, destroying any barrels or
    killing any Pain Elementals in your way. When you get to the other end of the
    room, hit the switch in front of you.
    
    When you hit the switch, go right, and drop down to the floor below you. Down
    here again, go all the way right (to the door we opened at the start). You'll
    see that a lift has appeared in front of the door. Lower the lift, and get on
    it. Ride it to the top. At the top, turn left, and *run* to get to the new
    platform. When you get on this platform, go all the way left to the other end
    of the room, killing any Imps, Pain Elementals, Lost Souls, or Demons in your
    way. When you get to this end of the room, go through the opening. In here,
    *run* straight through this hall way, and if you were running, you'll make it
    to another platform. On this platform, turn right. You'll see a huge opening.
    Now *run* across the gap to try and get to it, but instead, it will teleport
    you to the opening.
    
    Over here, go through the opening to your left. Follow this hall to an opening
    to the right. Before you go in it, kill all the Imps in the opening. When the
    Imps are gone, go in the opening, and hit the only switch in here (it's a
    door). When the door opens, go through, and collect the Soul Sphere. Now exit
    this small room, and leave this room too.
    Back out here, go right, and through the opening. Back in this room, a new
    opening has revealed, containing a Spider Mastermind (on hard skill levels),
    and a few Arachnotrons. Kill each of the Arachnotrons, and the Mastermind (have
    the Arachnotrons kill it). When they're all dead, go through the opening they
    came from, pick up the Yellow Key, and go through the teleporter.
    
    When you teleport to this room, turn around, and follow this hallway to two
    teleporters, killing any Revenants, Demons, or Arachnotrons in your way. When
    you get to the two teleporters. Take the one on the left. When you teleport, go
    all the way straight and open the door. In here, open the Yellow Door to your
    left. Follow this hall to a barrel, and destroy it. Now follow this hall to the
    exit teleporter. Take it.
    
    --------------------
    Level 24: The Chasm
    --------------------
    
    This level is really annoying on any skill level, so save at all times, because
    this level has very thin platforms, and you can easily fall to the slime below
    you. Anyways, when you start this level, cross the pathway in front of you
    carefully, and open the door at the end of the pathway. In this room, kill any
    Imps you find, and look around this room for the Blue Key. When you have the
    Blue Key, leave this room.
    
    Back out here, cross the pathway in front of you back to the level's starting
    point. When you get to the end of the pathway, go right, and follow this
    pathway to the Blue Door. Open it, and save your game. In this room, walk
    across the very thin pathway in front of you slowly before you fall down. Go
    straight until you see a pathway to your right. Take it. Follow this pathway
    until you can access a pathway to your right (remember to cross these pathways
    slowly). When you get to the pathway to your right, cross it and when you get
    to the end of this pathway, turn left, and then right to a bigger platform.
    Step on it (it's a teleport).
    
    In this room, save your game. Also, the pathways are a bit bigger in this room.
    When you get here, cross the pathway in front of you until you see a pathway to
    your right and left, killing any Lost Souls in your way. When you get to these
    two pathways, take the one on the left. Follow this pathway to two teleporters.
    Collect the health and ammo here, and take the silver teleporter.
    
    In this room, kill the Demons in front of you. From where you were when you
    entered this room, go right, and hit the switch over here. When you hit it,
    turn around, and *run* all the way straight to the other end of the room, and
    get on the lowered platform over here. Also, kill the Demons over here too.
    When the platform rises to the top, hit the switch up here, turn around, jump
    off this platform, and go left to a new lowered platform. Kill the Demons over
    here, and when the platform rises to the top, hit the switch up here. The wall
    in front of you will lower, containing the Red Key.
    
    When you have the Red Key, turn around, jump off this platform, and get to the
    other end of the room. Over here, hit the switch, and the wall in front of you
    will lower. Kill the Demons over here, and take the teleporter. Back in this
    room, get back on the pathway in front of you. On this pathway, follow it to
    the Red Door in this room. When you get to the Red Door, open it. You'll see
    another door. Open this one too. In this room, open the exit door, and go
    through the exit teleporter.
    
    ---------------------
    Level 25: Bloodfalls
    ---------------------
    
    You better have a good amount of health when you start this level, or you won't
    make it. Anyway, go in the opening across from you. You'll drop down to a lower
    floor, and there's blood where you're standing (and you get hurt when you stand
    in it). Down here, kill the Former Human Sergeants in front of you, and go
    straight,
    through the opening. In this non-toxic room, go straight, and lower the lift
    across from you. When it lowers, you'll see a new opening. Go in it. In here,
    follow the left wall to a room with a teleporter, killing any Imps, Hell
    Knights, or Former Human Sergeants in your way. When you get to the teleporter,
    go
    through it.
    
    In this room, kill the Lost Souls in front of you, and also get the Blue Key in
    front of you. When you have the Blue Key, drop down to the floor to your right.
    Down here, kill the Former Human Sergeants and the Pain Elemental, and go up
    the stairs.
    At the top, go right, and walk up to the door. It will open. In here, go
    straight to the other end of the room, and take the teleporter. You'll be
    warped back to the level's starting point. Again, go through the opening in
    front of you, and down here, go through the opening across from you again.
    
    In this familiar room, lower the lift again. When it lowers, get on it. This
    time, ride it to the top. When it gets to the top, go all the way right to the
    Blue Door, killing any Former Human Sergeants or Former Commandos in your way.
    When
    you get to the Blue Door, open it. In here, kill the Former Humans, Former
    Human Sergeants,
    and Imps in front of you. When all of the enemies are gone, go through the only
    opening in this room, and lower the lift. Once the lift is on the ground, get
    on it. Ride it to the top.
    
    Up here, kill the Hell Knight in front of you, and go straight. In this room,
    go through the only opening in here, and head down the stairs. Down here, walk
    on the lift in front of you, and it will lower to a lower ground. Down here,
    get to the lift across from you while it's lowered. Ride it to the top. Up
    here, kill the Imps, Former Commandos to your left, and the Arch-Vile. When
    they're all gone, check the pillars in this room. One of them has a switch. Hit
    it, and another pillar in front of you will lower, revealing the exit
    teleporter. Take it.
    
    ------------------------------
    Level 26: The Abandoned Mines
    ------------------------------
    
    Collect the health and armor in here (and the Super Shotgun), and hit the only
    switch in this room. The floor you're on will lower. Down here, go all the way
    straight, killing any Former Commandos in your way. When you get to the other
    end of the room, turn left, up the stairs. Up here, go straight to the other
    end of the room, and hit the switch over here. When you hit it, a Cacodemon
    behind you will appear. Kill it, and when it's dead, go back down the stairs,
    through the new opening to the left.
    
    In here, follow this pathway to the Red Key, killing any Imps in your way (if
    you can't see the Key you'll pick it up eventually). When you have the key, go
    back to the opening you used to enter this room. It should've closed. Hit the
    switch near here and it will open again. Now exit this room. Back out here, go
    straight and you'll see an opening to your right. Take it, and go straight to
    the other end of the room. Over here, open the Red Door.
    
    In this room, get to the Medikit across from you. When you get to it, the floor
    in front of you will raise, revealing the Blue Key and a Baron. Kill the Baron,
    get the Blue Key, turn around, go straight, and exit this room. Back in this
    room again, go all the way straight to an opening, killing any Imps or
    Cacodemons in front of you. When you get to the opening, go through it, and
    follow this pathway to the Blue Door, killing any Imps or Cacodemons in your
    way. When you get to the Blue Door, collect the ammo near it, and open the Blue
    Door.
    
    In this room, take either pathway to the other side of the room, killing any
    Lost Souls, Barons, or Cacodemons in your way. When you get to the other end of
    the room, take the pathway leading to the center of the room, and follow it to
    a platform. Kill the Mancubus in front of you, and grab the Rocket Launcher
    Ammo and get the Yellow Key. Now exit this room.
    
    Back in this room, follow the same pathway to an opening, killing any
    Cacodemons in your way. When you get to the opening, enter it. In here, go
    straight until you see an opening. Go through it. In here, go straight until
    you see an opening to your right, killing any Cacodemon in your way. Once you
    see the opening to your right, go through it, and then take the staircase to
    your left. At the top, go straight, and then right, into the opening. In here,
    remove the Yellow Bar, and open the exit door. In here, go through the exit
    teleporter.
    
    ------------------------
    Level 27: Monster Condo
    ------------------------
    
    At the start, walk up to the pit in front of you. When you get to the pit, go
    right, towards to door in front of you. When you get to the door, open it. In
    this room, walk up to the Rocket in front of you. The wall in front of you will
    lower, and the door will shut behind you. When the wall lowers, kill the
    Former Humans, Former Human Sergeants, Former Commandos, Imps, and Demons in
    front of you.
    
    When all of the enemies are gone, get your back on the door you used to enter
    this room (it currently won't open). With your back on the door, get to the
    other end of the room. When you get to the other end of the room, turn right to
    the wall. On this wall is a switch. Hit it. The wall in front of you will open,
    revealing a few Hell Knights and an Arch-Vile. Kill all of them, and go into the
    room they came out of.
    
    In this room, grab the Plasma Gun, Invincibility Sphere, and the Yellow Key.
    When you have the Yellow Key, hit both switches in this room. One of the
    switches will cause the wall behind you to open, revealing ammo, a Hell Knight,
    and another switch (still hit the other switch too). Kill the Hell Knight. When
    it's gone, go into the small room it came out of, and hit the switch in here.
    The wall behind you will open. Get back out here, and exit this room back into
    the level's starting room.
    
    Back out here, turn right, facing the pit. You should see a spiral staircase in
    the pit leading to a platform with a Rocket Launcher. Go up the stairs, and at
    the top, get the Rocket Launcher. When you get the Rocket Launcher, turn
    around. You'll see another part of the room alone in front of you next to the
    pit. From where you are, *run* straight to get across this pit onto that part
    of the room.
    
    Over here, open the only door over here. In this room, go straight. As you go
    straight, you should see a switch on the wall to your left. Hit it. The floor
    you're on will lower. Down here, kill the Imps and Demons, and open the door.
    In this room, collect the health and ammo, and open the Yellow Door.
    
    In here, take either staircase to the left or right to the Blue Key. When you
    get the Blue Key, take out your Chainsaw, Pistol, either Shotgun, or the
    Chaingun, and shoot the Demon Head on the wall the Blue Key was in front of.
    When you do, the wall in front of you will open. When it opens, kill the
    Revenants in front of you. When they're all gone, hit the switch in the room
    they came out of, and collect the ammo.
    
    When you hit the switch, the Yellow Door behind you will open again. Get to the
    door and go through it before it closes again, and DO NOT step on the tile in
    the middle of the room. Back out here, hit the switch to the right of you. Once
    you hit the switch, stairs to the left of you will rise to a higher platform.
    Go up the stairs, and at the top, kill the Hell Knight in front of you. When
    it's dead, climb up the staircase up here, and press the Spacebar on the face
    tile on the wall. It will open.
    
    Back in this familiar room, kill any new Revenants that might've appeared. If
    not, from where you just entered this room, go straight, to the other end of
    the room. Over here you'll see a Blue Door on the wall to the left. Open it.
    Hit the switch in front of you. A wall behind you will lower, revealing Hell
    Knights and a Baron of Hell. Kill all of them, and on the wall that lowered,
    collect the Soul Sphere and the Red Key.
    
    When you have the Red Key, turn around and face the Blue Door. Also on this
    wall to the left of the Blue Door is another door. Open it. In here, there are
    two switches across from you at the other end of the room. Hit the one on the
    left. Once you hit it, the wall you're on will lower. Down here, kill the Lost
    Souls and the Hell Knight in front of you. When they're all dead, collect the 3
    Backpacks, and go through the opening to the left. In here, kill the Arch-Vile
    in front of you, go straight, and open the Red Door. In here, go through the
    exit teleporter.
    
    ---------------------------
    Level 28: The Spirit World
    ---------------------------
    
    From your starting point, go in the opening across from you. In here, follow
    this hall to another opening, and before you get to it, you'll see Imps,
    Demons, and Pain Elementals. Kill all of what you see. When the enemies are
    gone, go through the opening and drop down.
    
    Down here, you'll see a small lava river in front of you. Get to the left of
    it, and when you do, follow this lava river to a small opening (staying on the
    left, and the opening has a red wall behind in). Get in the small opening, and
    drop down to the floor below you.
    
    Down here, equip your BFG, and follow this hall to an opening. Go through the
    opening, and in this room, go right, and drop down to the floor below you. If
    you are playing on high skill levels, you'll see a Spider Mastermind in front
    of you. Use your BFG to kill it too. When the Mastermind is gone, go straight
    until you see an opening to the right. Go through it, and head up the stairs.
    
    In this room, go right, and get to the other end of the room. Over here you'll
    see the weird looking "chair" in front of a wall that has a Demon Head on it.
    "Sit" on the chair (get on it). When you hop on the "Chair", turn around. The
    platform in the middle of the room has lowered. Get on it, and it will raise
    again.
    
    Once it raises as high as it can go, face the "chair" and turn left. You'll see
    a wall of skull heads right next to you. You'll notice one of them has Red
    Eyes. Walk up to it and press the Spacebar. When you do, drop down to the floor
    on your right. Down here again, go straight and you'll see an opening to your
    right. Go through it and pick up the Yellow Key.
    
    Once you have the Yellow Key, turn around, and go left, to the other end of the
    room. Over here, go through the opening and head down the stairs. Down here,
    kill any Arachnotrons or Spider Masterminds in front of you with your BFG (you
    can use the Invincibility Spheres down here too if you need too), and once all
    of the enemies down here are dead, open the Yellow Door in this room.
    
    In here, go up the stairs. At the top is this funky colored wall. Press the
    Spacebar on it, and it will open. When it opens, kill any Hell Knights or
    Revenants in front of you. Then go straight until you see an opening to your
    left. Go through it. In here, go right. Over here, you'll see white walls to
    the left, and you'll also see lava in between the white walls too.
    
    Walk up to the lava, and press the Spacebar (it's a lift, and it will lower).
    When it lowers, get on the lava, and when it raises again, go all the way
    straight to the platform across from you that has Green Torches up top (it's
    too high to get on, but now there is a new lift to your right that you can use
    it to get on it).
    
    When you get to the wall/platform, go right and lower the lift (it has skull
    heads on it too). When it lowers, get on it, and when it rises to the top
    again, follow this hall back to the level's starting room. In this room, open
    the Yellow Door. Once the door is open, pick up the Red Key in front of you.
    
    Once you got the Red Key, turn around and go through the opening in front of
    you before you get caught in a major Revenant jam. In this hall again, follow
    it to the same opening, and drop down to the floor below you again. Down here,
    follow the right wall to a small opening. You'll know it's the right opening if
    Demons are coming out of the wall.
    
    When you're in the right opening, kill the Demons that come out of the wall.
    When the Demons are dead, walk through the wall they came out of (you can walk
    through this wall), and in this room, kill the Demons and Spectres in front of
    you, and grab the health and ammo in here. When the Demons and Spectres are
    gone, go through the opening in this room. In here, look right, facing the
    wall.
    
    One of the walls in front of you has a big circle on hit. Shoot it with your
    Fist, Chainsaw, Pistol, either Shotgun, or your Chaingun. Once you hit that
    part of the wall, turn left, and a door will open. Go through the new opening.
    In here, open the Red Door (it's a switch) before any Revenants or Arch-Viles
    get you. Once you open the Red Door, go straight, and go through the exit
    teleporter.
    
    -------------------------
    Level 29: The Living End
    -------------------------
    
    From your starting point, go straight and get the Medikit and Chaingun across
    from you. Once you step on the floor they're on, it will lower. Down here, kill
    the Imps/Former Human Sergeants/Former Commandos/Spectres. When they're all
    gone, take
    their weapons, and get the Medikit here. Then, hit the only switch down here.
    Once you hit it, turn right. You should see a pathway rising.
    
    Once the pathway fully rises, kill the Former Human Sergeant on it, and get the
    Armor on
    it too. Then, take this pathway to another room. In here, kill all of the Imps
    in front of you. When all of the Imps are dead, switch to your Automap. See the
    north part of this room on it? When you do, switch back to first person mode,
    and get to the north part of this room. When you do, walk up to the Box of
    Shotgun Shells, and when you do, turn around. Part of the building in front of
    you has opened, revealing a switch. Go straight and hit it.
    
    When you hit the switch, turn around. Now kill the Pain Elementals and
    Cacodemons in front of you (use Rocket Launcher, Plasma Gun, or BFG). When all
    of the enemies are gone, go into the room the came out of. In here, turn right,
    and get on the pathway. Follow this pathway to a teleporter, killing any Heavy
    Weapon Dudes or Imps in your way. When you get to the teleporter, take it.
    
    Once you teleport, collect the health and armor around you, and climb up the
    staircase (watch out, it is a little bit curved). At the top, follow this
    hallway to a pedestal, killing any Imps or Revenants in your way. When you get
    to the pedestal, walk up to it, and turn around. Part of the wall in front of
    you should've opened. Go into the new opening across from you.
    
    In here, get to the other end of the room. Over here, kill the Hell Knights,
    and hit the switch. Now turn around and exit this room. Back out here, turn
    left. You'll see that the pedestal has been removed. Now, get to where it was,
    and when you do, back up a little bit, and then *run* straight to get to the
    platform across from you. On this platform, kill the Hell Knight, and pick up
    the Soul Sphere.
    
    Also on this platform, hit the switch. When you do, parts of the walls around
    you will open, revealing Cacodemons. Kill all of them. When all of the
    Cacodemons are gone, wait for the pathway to raise up to this platform (the
    pathway is going to be to the left of the switch you hit).
    
    Once the pathway raises up here, take it. It will lead you to three openings.
    Take the one in the middle first. In here, drop down to the pit in front of
    you, and go straight to the switch. Hit it. When you do, a pathway behind you
    will rise. Get to the pathway, and press the spacebar to lower it. Now get on
    it (kill the Cacodemon if you need to). Ride it to the top.
    
    With the new pathway created, take it to the new opening. Now pick up the Super
    Shotgun, and kill the Cacodemons and Pain Elementals in front of you. When the
    enemies are gone, drop down to the pit below you, and go through the opening to
    your left. In here, hit the switch. Once you hit the switch, a new pathway
    behind you will raise. Walk up to it, and press the spacebar on it to lower it.
    
    Before you get on the new pathway, go straight and get to the opening across
    from you. In here, hit the switch. Now turn back around and lower the pathway
    again. Ride it to the top, and when it raises again, follow it to a new
    opening. In here, follow this pathway to another room.
    
    In this room, kill the Mancubus. Now hit the switch in here. Once you hit the
    switch, leave this room (keep following the pathways to the pathway that leads
    to three openings). Back out here, go right, then right again, through this
    opening. In here, kill the Former Human Sergeants and Imps in front of you.
    Down here,
    hit the only switch in this room.
    
    When you do, turn around. You should see the floor raise (it's a lift too).
    Walk up to the raised floor, and press the spacebar to lower it. When it gets
    down to the ground, get on it, then ride it to the top. Up here, kill the
    Arch-Vile in front of you, and go into the room it came out of.
    
    In this room, hit the only switch in here. Now leave this room. Back in here,
    follow this pathway to an opening. Go through it. In here, follow this hall to
    an opening to your left. Go through it, and go straight, crossing the new
    pathway. At the end of the pathway, go into the room in front of you, and hit
    the switch.
    
    When you hit the switch, turn around, and get on the pathway. Now drop down to
    the left, and leave this room. Back out here, go all the way left, then left
    again, into the only opening we haven't gone through yet. In here, go straight,
    and open the door. In here, walk up to the wall in the center of the room. On
    the left part of the wall, there are scratches.
    
    Walk up to the scratches, and press the Spacebar. The wall will open, and in
    this room, grab the health and ammo, and go through the teleporter. In this
    room, kill the Revenants, Former Human Sergeants, and Former Humans in front of
    you. When
    they're all gone, walk up the stairs in front of you. At the top you should see
    3 pathways. Get in center with the one in the middle, back up, and *run*
    straight to get to the pathway.
    
    Once you're on the pathway, follow it to another platform, killing any Shotgun
    Guys in your way. When you can see the platform, kill the Revenant on it, and
    when it's gone, get on the platform it's on, and hit the switch. Now get back
    on the pathway, and on the end of it, drop down in the pit to the right. Down
    here, go straight, and when you get to the lift at the end of the room (it's to
    the left), lower it and get on it. Ride it to the top.
    
    Up here again, turn around, facing the three pathways. Now back up, and *run*
    to get the one on the left. Follow it to a platform with a Pain Elemental on
    it, killing any Former Human Sergeants in your way. When you get to the
    platform, kill
    the Pain Elemental on it, then get on the platform it was on. Hit the switch on
    it. Now turn around, get on the pathway, and get to the end of it.
    
    When you do, drop down to the right, get to the lift, and lower it. Ride it to
    the top. Up here again, face the three pathways again, and this time, get on
    the one to the right (like the other two, run to get on it). Once you get on
    this pathway, turn right. You'll see an opening. Back up, and *run* through the
    opening to get to the platform across from you.
    
    On this platform, kill the Mancubus. When it's dead, hit the switch on this
    platform, lower the lift to your right. Get on it, and ride it to the top. At
    the top, turn right. Once you turn right, *run* straight to get across the gap,
    and to get back in the room across from you. In here, turn right, and take the
    pathway to the right again. Follow this pathway to another pathway (they aren't
    connected). When you see the new pathway, get in center with it, and *run*
    across the gap to get on the pathway. On this one, kill the Barons of Hell in
    front of you, and when they're gone, get on the pathway they were on, and take
    the teleporter.
    
    When you teleport, head up the stairs in front of you. Follow them to a higher
    platform. At the top, get to the other end of the room, and go through the exit
    teleporter (do not fall in the pit in the middle, it contains a Cyberdemon, and
    this pit will raise to the top, so hurry up and exit this level).
    
    ----------------------
    Level 30: Icon of Sin
    ----------------------
    
    Congratulations, you have made it to the final level of Doom II! Anyways, when
    you start this level, you start standing on a Backpack. Collect all of the
    weapons in this room, all of the ammo, and the Megasphere. Now go through the
    teleporter in this room. When you teleport, the final boss of the game is
    across from you (it's a large demon head on the wall).
    
    The final boss also shoots out skull headed boxes from it's brain, containing
    an enemy (it won't be a Former Human, Former Human Sergeant, Former Commando,
    Lost Soul,
    Spider Mastermind, or Cyberdemon).
    
    Also, go left, and then at the end of this platform, go left again. You should
    see a Demon Head figure on the wall. Press the spacebar on it, and the platform
    will lower. On this platform, go all the way straight, and you should see
    another Demon Head figure on the wall. Press the spacebar on this figure and
    the platform will lower. On this platform, wait for it to raise to the top. At
    the top, go through the only opening up here. In this opening, hit the switch.
    
    Now turn around. You should see a pillar rising. Wait for it to get as high as
    it can go, and try to kill any enemies distracting you. Once the pillar gets as
    high as it goes, go all the way straight, to the pillar, and press the Spacebar
    to lower it. When it gets to the ground, get on it, and equip your Rocket
    Launcher (it's the only weapon that can defeat the final boss). Now, facing the
    final boss, wait for the pillar to raise again.
    
    See the final boss's brain? As the pillar is raising, time your Rockets just
    right so it can get through the brain (you'll hear a loud scream). Weather you
    get it through or miss, get to the ground, lower the pillar again, and keep
    firing your Rockets into his brain. Repeat this twice more to win (3 hits in
    total).
    
    Once you defeat the final boss, congratulations! You also get a story too:
    ------------------------------------------------------------
    The horrendous visage of the biggest demon you've ever seen crumbles before
    you, as you pump your rockets through his exposed brain. The monster shrivels
    up and dies, its thrashing limbs devastating untold miles of Hell's surface.
    You've done it. The invasion is over. Earth is saved. Hell is a wreck. You
    wonder where the bad folks will go when they die, now. Wiping the sweat from
    your forehead you begin the long trek back home. Rebuilding Earth ought to be a
    lot more fun than ruining it was.
    ------------------------------------------------------------
    The next screen shows the cast of enemies. Press the spacebar (or any other
    key) to get to the next enemy.

    12.) Doom II Secrets
    ----------------------------------------
    Ever needed help finding a secret in any of the levels from Doom II? If so,
    this is the section to look at. I will cover each secret from each level in
    this section and how to get to them.
    
    ------------------
    Level 1: Entryway
    ------------------
    
    Number of Secrets: 5
    
    1. For the first level, most of the secrets here are worth it. Start this level
    by going through the opening in front of you. In here, open the door to your
    left and go through it. In here, you'll see a platform on the left and right.
    Both of them have a switch on them. Hit the switch on the right platform and a
    wall across from you will open, so go through it. In this secret area are two
    Stimpacks and a Security Armor.
    
    2. Now, leave this room. Back in this hall, go through the opening across from
    you. In here, go through the opening at the other end of this room. In this big
    room, lower the lift to your right, get on it, and ride it to the top. Up here,
    open the hidden door in front of you and go through it. In this secret area,
    there is a switch. It'll be a part of your next secret.
    
    3. From secret 2, hit the switch. Now turn around and drop back down to the
    floor below you. Down here, get to the exit door and then turn around. You'll
    see a new opening, so go through it. Out here, kill all the Imps and get the
    Shotgun and Shotgun Shells in this secret area.
    
    4. Now, go back to the lift that takes you to secret 2. Get on it and ride it
    to the top. Up here, face the switch and then turn around. You'll see a small,
    square platform on the floor. Back up and RUN off the lift to get onto this
    platform. Once you step on the platform, step off of it and then go back into
    the hall to your left. Back in here, turn right to the health potions and
    you'll see an opening. Go through it and you'll be in a secret area with the
    Rocket Launcher in it. Nice getting it this early.
    
    5. From here, go to the exit door. Once you get to the exit door, face the Imp
    cage to your right. Now, press the Spacebar on the walls to your right until
    you find a hidden door (an Imp would come out and open it). Once you find it,
    go through it. In this secret area is an Imp and a Stimpack.
    
    --------------------
    Level 2: Underhalls
    --------------------
    
    Number of Secrets: 1
    
    1. Once you start this level, progress the game until you have the Red Key.
    Once you have the Red Key, turn left and press the Spacebar on the walls until
    you find a hidden door. Once you find it, open it and it will reveal a hidden
    room, so go through it. In this secret area is a Combat Armor and a teleporter
    leading back to the level's starting point.
    
    ---------------------
    Level 3: The Gantlet
    ---------------------
    
    Number of Secrets: 1
    
    1. From the start of the level, open the door in front of you. Now in here,
    head up the stairs to your right. At the top, lower the lift in front of you,
    get on it, and ride it to the top. Up here, save your game. Now turn right and
    you'll see a little "well" in the water pit. Being on this platform, face the
    well and then hold SHIFT, ALT, UP and RIGHT on the keyboard and then run off
    the ledge on the staircase. If you did it right, you'll land in the well. Down
    in this secret area, there is a Soul Sphere, Energy Cell Pack, a Combat Armor,

    Number of Secrets: 18
    
    1. 18 secrets! Holy crap, well, here I go. Start the level by heading down the
    stairs in front of you. Down here, go through the opening to your right. Out
    here, use either walkway to your right or left to get onto a higher platform.
    On here, notice all of the rectangular structures. Each of them is a secret. To
    open up two of them for now, walk to the door at the other end of the room and
    you'll hear the sounds of a door opening. Turn around and the two buildings in
    front of you have opened. Walk through one of them to get a secret. Inside will
    be health potions and a Stimpack.
    
    2. The other building that was opened is right across from secret 1. Go through
    this one while it's open to get credit for another secret. You'll find another
    Stimpack and more health potions.
    
    3. From these two buildings, face the door you walked up to open up secrets 1
    and 2. Face it and turn around. You'll see an opening to your left, so step
    through it and you'll hear another door open. Turn right and you'll see another
    building open, so walk through it to get credit for a secret. In here will be
    ammo and health and a nice secret.
    
    4. Now, you also saw a building right next to the opening you walked into. To
    open up that building, go through the opening to your right and you'll hear the
    sound of a door opening. That is the building on the opposite end where the
    opening was, so run to it and walk through it to get credit for a secret. In
    here will be more health and ammo.
    
    5, 6, and 7. From secret 4, go through the opening to your left. In here, go

    open, so go through it. In here, follow this long hall to a room with a
    Megasphere. Each step to the Megasphere counts as a secret, so once you get to
    the Megasphere, you'll have credit for 3 secrets.

    has a "UAC" symbol on the wall. Shoot the symbol and it will open, revealing a
    Soul Sphere. Pick it up to get credit for a secret.

    Key, turn around and hit the switch in the alcove in front of you. A wall
    behind you will open, revealing a hall with armor bonuses. Walk up to them to
    get credit for a secret. This hall leads you to the Blue Key, but we'll come
    back later.
    
    10. From secret 9, go back into the room with the alcoves. Back in here, turn
    left and you'll see an alcove across from you with the UAC symbol on it. Shoot
    it and it will open, revealing another secret area. In here is a Berserk,
    Rockets, and armor bonuses, and your own credit for a secret.

    alcove, there is another one with the big UAC symbol. Shoot that and it will
    open, revealing a secret area. Step through to get credit for a secret. Also,
    there are health and armor bonuses plus a Backpack.
    
    14. In secret 13, go to where the Backpack is. Open the hidden door in front of
    you and then walk through. You'll be teleported. Up in this secret area, there
    is a Box of Bullets and an Invincibility Sphere, even though there is an
    Invincibility Sphere just below you. You'll get credit for a secret once you
    are teleported.
    
    15. From secret 14, drop down to the floor below you. Down here, go through the
    opening across from you. In here, head down the stairs. Down here, open the
    door in front of you and leave this room. Out in this big room, go through the

    16. From secret 15, turn around and you'll see a Rocket Launcher on a pedestal.
    Pick it up and then RUN onto the platform in front of you. You'll get credit
    for a secret when you get on this platform. On here is an Armor and two
    Medikits.
    
    17. Now leave this room. Back out here, go all the way straight to the other
    end of the room. Over here, you'll see two different sets of walls with black
    spots on them. Both of these are hidden doors. Open the one on the left and it
    will open, revealing a Berserk, Box of Rockets, and plenty of armor bonuses.
    Step into this room to get credit for a secret.
    
    18. Now go to the other wall with black spots on them. Open this door and it

    head up the stairs in front of you. At the top, walk forward and you'll hear
    the sound of a lift dropping. It is at the bottom of the stairs to your right,
    so get on it and ride it to the top. Up here, look for a different-designed
    wall on the left. This is a hidden door, so open it and then drop down to the
    floor below you. Down here, drop down to the walkway and get the Invisibility
    Sphere.
    
    2. From secret 1, progress the game until you get the Blue Key. Once you get
    the Blue Key, face the pillar with the Red Key from its east side. Once you do
    that, turn around and face the pit on the left side of the walkway. You'll see
    a new opening in the pit to the left, so drop down to it and go through the
    opening. In here, you'll get credit for a secret, but if you follow this
    hallway you'll get to a teleporter and Boxes of Rockets. If you step through
    the teleporter, you'll be taken onto the platform with Energy Cell Packs. Also,
    the platform with the Red Key is across from you, so you can RUN onto it and
    get the Red Key early. Nice shortcut.
    
    3. Unless you took the shortcut to the Red Key, progress the game until you
    have the Red Key. Once you have the Red Key, open the Red Door and go through
    it. In here, you'll see an Invincibility Sphere behind a cage. To get this,
    walk up to the bars to the right and they will open. Now press Spacebar on the
    black and gray wall and it will open, so go through it. Now you will get credit

    you'll have a Soul Sphere on a pillar. Ignore this for now. Instead, search for
    two Blue Doors. Open the Blue Door on the southeast side and go through it. In
    this room there is a huge lava pit and a switch at the other side of the room.
    To get across this path, notice the tiles on the ceiling. Follow them to the
    switch to make a long pathway so you won't be hurt from the lava. Once you get
    to the switch, hit it. Now go back to the door. Back over here, hit the switch
    next to this door to open it. Now leave this room. Back out here, go through
    the new opening across from you. In this secret area, follow either hallway to
    a BFG.
    
    2. From secret 1, leave this room. Back out here, open the Blue Door on the

    around and you'll see a pit, so drop down it. Once you fall, you'll get credit
    for a secret. On this platform are two Boxes of Bullets. Below you is a Berserk
    and a hallway leading back to the two Blue Doors and everything else in this
    room.

    Up here, get onto the platform with the Chaingun and you'll get credit for a
    secret.
    
    4. In this same area, you'll notice a teleporter in the corner of the room. Use
    the stairs to get to the teleporter and then step onto it. Once you are
    teleported, hit the switch next to you and the floor you're on will rise. Up
    here, you'll notice you'll be on the pillar with the Soul Sphere on it. Collect
    the Soul Sphere for credit for a secret.

    Level 14: The Inmost Dens
    --------------------------
    
    Number of Secrets: 0
    
    There are no secrets in this level, which means you can only get 0% for a

    be counted on your secrets score.
    
    ------------------------------
    Level 15: The Industrial Zone
    ------------------------------
    
    Number of Secrets: 11
    
    Even though there are 11 secrets in this level, you can only get a maximum
    secrets score of 90% without cheating. This is because one of the secrets was
    placed on the smack middle of a teleporter, and a player cannot get credit for
    a secret without stepping on it before being teleported away. Now, on with the
    secrets.
    
    1. From the start of the level, open the door to your left and go through it.
    In here, hit the switch on the wall and the lift you're on will lower. Down
    here, go through the opening in front of you. Out here, go through the opening
    to the right of the building in front of you. The building across from you
    should be surrounded by a lava moat. Head up the stairs to enter the building.
    At the top, face the Rocket Launcher and then turn around. You'll see a
    teleporter on a platform, so back up and RUN onto it to the teleporter. Now
    step on it. Once you're teleported, you'll be on a walkway.
    
    RUN FORWARD to land on another walkway. On here, hit the switch and then drop
    down into the building to your left. Down here, step through the teleporter.
    Once you've been teleported, step back through the same teleporter. Once you've
    been teleported, pick up the Red Key in front of you. Now if you see that small
    little gap, drop down to it for a Berserk. Now press Spacebar on the crate for
    it to lower. Once it's been lowered, step on it for credit for a secret.
    
    2. In this same room, step back through the same teleporter again. Back on
    here, walk forward and you'll see a window to your left, so drop down into it.
    Down here, leave this building. Now go back into the same Red Key room and step
    onto the same teleporter. On here, go back through the same window and you'll
    land on a higher ledge. Now cross it and you'll see a platform with a Chaingun
    and Box of Bullets on it. RUN onto it to get credit for a secret.
    
    3. From here, drop down to the floor below you and leave this building. Back
    out here, turn left and then head left. Now go all the way straight and you'll
    stop at a lift. Hit the switch next to it to lower it. Now get on it and ride
    it to the top. Up here, open the Red Door and go through it. In here, look for
    an Invisibility Sphere. Once you find it, turn left to the wall. This is a
    hidden door, so open it and go through it. You'll drop down to a lava pit and
    get credit for a secret. Down here is a Box of Rockets and a Backpack.
    
    4. While you are in secret 3, use the lifts to get out of here. Back out here,
    get back to the Red Door and go through it. This time, follow this hall to a
    teleporter and then step through it. On here, use the switch to lower the lift
    next to you. Now get on it and ride it to the top. Up here, go through the
    opening next to you. In here, get to the BFG and a wall in front of you will
    open, revealing the Yellow Key. Pick it up and then turn around. Hit the switch
    on this pedestal and then head up the stairs. At the top, turn left and then
    drop down to the floor to your left.
    
    Down here, skip this torch and follow it to another torch. Face the huge pit
    next to this torch. Save your game and RUN on the gap, trying to land onto the
    pedestal. If you do, get the Radiation Suit and hit the switch. If not, load
    your saved game and try again. In the pit, a door will open across from you
    once you hit the switch. Go through it and it will take you to an Invincibility
    Sphere. Pick it up for credit to a secret.
    
    5. From secret 4, use the teleporter near the building to get back on here.
    Back on here, turn around and head up the stairs. At the top, RUN across the
    gap to get onto a platform. On here, open the Yellow Door and go through it. In
    here, follow this lava river to a switch. Once you get to it, hit it. Now
    follow this back to an opening. Back in here, head up the long staircase to
    your right. At the top, lower the lift in front of you, get on it, and ride it
    to the top. Up here, you'll be on top of the castle. Follow this path to a
    switch and then save your game.
    
    Hit the switch and drop down to the floor to your right. Back down here, open
    the Yellow Door. In here, go through the opening next to you. In here, get on
    the lift while it's still lowered. If not, load your saved game. Now ride it to
    the top. Up here is a Plasma Gun and a secret area.
    
    6 and 7. Now the fun part of the secrets. Drop down to the floor below you.
    Down here, head up the staircase across from you. In this little hall, remove
    the Yellow Bars and follow this to another Yellow Door. Once you get to it,
    open it and go through it. In here, walk forward and the wall in front of you
    will lower. Now follow this path and RUN to the end of it. At the end, you
    should see a window with a Megasphere in it. If it closes, start at the
    beginning of the path again. If not, RUN into it to get credit for two secrets.
    
    8. From secret 7, head back up the stairs next to you. At the top, walk forward
    and the wall in front of you will open. Facing it, turn around and back up
    until you see a wall across from you open. Once you see it, go through it. In
    here, you'll get credit for a secret. There are two Energy Cells to the right.
    
    9. In secret 8, go through the opening to your right. In here, hit the switch
    to your left. Now go back into the previous room and you'll see a teleporter.
    Step onto it and you'll be right in front of a Chainsaw. You will also get
    credit for a secret.
    
    10. Now, with all of this said and done, you should have the secret area
    accessible by now. Step into the hallway leading to the secret exit teleporter
    and you'll get credit for a secret. Finally you're done with this crazy level.

    pressing the Spacebar on the corner until the lava rises up to the walkway so
    you can get out.
    
    ---------------------
    Level 25: Bloodfalls
    ---------------------
    
    Number of Secrets: 2
    
    1. From the start of the level, progress the game until you have the Blue Key.
    Once you have the Blue Key, drop down into the lava pit and then head up the
    stairs in front of you. At the top, walk up to the door and it will open. In
    here, walk forward until you see green tiles on the wall to your left. This is
    a hidden door, so open it and go through it. In this secret area, there are two
    Energy Cell Packs.
    
    2. From secret 1, progress the game until you get to the Blue Door. Once you
    are at the Blue Door, open it and go through it. In here, lower the lift across
    from you, get on it, and ride it to the top. Up here, turn left and face the
    walls to the left. If you notice, one part of the wall is slightly different
    designed than the others. This is a hidden door, so open it and it will reveal
    a BFG on low skill levels. If you are playing on hard skill levels, it will
    reveal...nothing. Still, you got to step through and get credit for your secret.
    
    ------------------------------
    Level 26: The Abandoned Mines
    ------------------------------
    
    Number of Secrets: 4
    
    1. Once you start this level, turn around. You'll see a different design on the
    walls to the left. This is a hidden door, so open it and go through it. In
    here, there is a pillar with a Plasma Gun on it. To get to it, step through the
    teleporter in the southwest pit. You'll be then taken to a pillar, so the RUN
    onto the pillar with the Plasma Gun on it. But you'll get the credit for a
    secret once you step into this room.
    
    2. Now go back to the level's starting point. Back in here, hit the switch in
    front of you and the floor you're on will lower. Down here, turn right to the
    wall and you'll see a weird design on it. This is a hidden door, so open it and
    go through it. In this secret area, there is a Backpack and some Shotgun
    Shells. Step into this room to get credit for a secret.
    
    3. From secret 2, progress the game until you have the Blue Key. Once you have
    the Blue Key, you'll see a demon face on the wall in front of you. This is a
    hidden door, so open it and it will reveal a switch. Walk into this room to get
    credit for a secret before hitting the switch.
    
    4. In secret 3, hit the switch. Now run back to the previous room and you'll
    see a lowered lift to your left. Get on this lift and ride it to the top. Up
    here, get the Combat Armor in front of you and turn right. On one part of the
    wall, it has a slightly different design than the others. This is a hidden
    door, so open it and go through it. In this secret area, there are a row of
    health potions. Follow them to a bigger room with a Soul Sphere.
    
    ------------------------
    Level 27: Monster Condo
    ------------------------
    
    Number of Secrets: 8
    
    Even though there are 8 secrets in this level, you can only get a maximum
    secrets score of 87% without cheating. This is because one of the secrets was
    placed on the smack middle of a teleporter, and a player cannot get credit for
    a secret without stepping on it before being teleported away. Now, on with the
    secrets.
    
    1. You need to be quick in getting to this secret, because after 30 seconds the
    wall will shut for good. From the start of the level, you'll see a spiral
    staircase across from you. Get to the bottom of it and RUN forward onto the
    platform across from you. On here, open the door and go through. If you got to
    this room in less than 30 seconds, turn left. You'll see Rockets, a Box of
    Bullets and a Box of Shotgun Shells. Quickly step into this area before it
    closes to get credit for a secret.
    
    2. From secret 1, go back into the previous door. Back in here, turn left.
    You'll see a green triangle with an eye across from you. Walk up to it and a
    wall in front of you will lower, revealing an Invisibility Sphere, Light
    Amplification Visor, and an Energy Cell. Step into this area to get credit for
    a secret.
    
    3. From secret 2, turn around. You'll see a blue flag on the wall to the left.
    To lower that, notice that pile of flesh next to it. Walk up to it to lower it.
    Now walk past the lowered flag. In this area, head left to the wall and it will
    open, revealing a Medikit, a Box of Shotgun Shells, and plenty of Armor
    Bonuses. Step into this area to get credit for a secret.
    
    4. From secret 3, progress the game until you have the Yellow Key. Once you
    have the Yellow Key, stay where you are. Wait for the wall to shut and then hit
    the switch that is on the wall. A wall behind you will lower, revealing a Box
    of Rockets, an Energy Cell, and a switch. Step into here to get credit for a
    secret. Also hit the switch if you want to get out of here.
    
    5. Go back to the level's starting point. Back in here, RUN over the spiral
    stairs onto the platform. On here, open the door and go through it. Back in
    this room (where secret 1 is to your left), open the door to the left of the
    Blue Door and go through it. In here, there are two switches across from you.
    Hit the switch on the right. Turn left and you'll see a new hole, so drop down
    into it. Down here, step into the narrow hall to get credit for a secret. There
    are plenty of health potions in here. The teleporter at the end is a secret,
    but it is right on the middle of it so you can't get credit for it before being
    teleported away.
    
    6. From secret 5, head into the teleporter. Once you are teleported, you'll see
    a BFG to your left. Anyway, progress the game until you get to the Yellow Door.
    Once you get to it, open it and go through it. In here, head up the stairs to
    your right. At the top, hit the switch next to you and turn around. You'll see
    a new room with a Computer Area Map, Berserk and a Soul Sphere. Step into it to
    get credit for a secret.
    
    7. Before you go to secret 7, get the Blue Key in this room first. Now notice
    the tile in the middle of this room. Step onto it to be teleported. Once you
    are teleported, head up either staircase next to you. At the top will be a
    Berserk, Soul Sphere, and a Computer Area Map. Step into this area to get credit
    for a secret. Because you can only pick up one Computer Area Map, you cannot
    get 100% items, because a Computer Area Map counts towards your item score.
    
    ---------------------------
    Level 28: The Spirit World
    ---------------------------
    
    Number of Secrets: 7
    
    1. Once you start this level, turn right and go through the opening in front of
    you. Now you'll be in a big room. In here, go through the opening to the right.
    If you turn left and look at the wall, you'll notice there is a candle in front
    of the wall. This is a hidden door, so open it and it will reveal a Soul Sphere.
    Collect it to get credit for a secret.
    
    2. There are still 2 more secrets in this room. Go into the next small opening.
    There is a candle in front of the wall to your left, so open this hidden door
    and it will reveal 4 Backpacks and a Medikit. Collect them all to get credit
    for a secret.
    
    3. Now go into the next opening. This time, the candle will be on the wall to
    the right. That means the hidden door is to the right, so open it and it will
    reveal a Berserk. Collect the Berserk so you can get credit for 3 nice and easy
    secrets. Now we can get out of this room.
    
    4. Progress the game until you get to that giant room with the Spider
    Mastermind. In this room, drop into the pit and head up the stairs across from
    the Yellow Door. At the top, step onto the chair across from you. A pillar
    behind you will lower, so step onto it and ride it to the top. You'll get
    credit for a secret for stepping onto this pillar.
    
    5. Stay on the lift. Up here, face the chair and turn left. You'll see on those
    wall of skulls, one of them has red eyes. That is a switch, so hit it. Turn
    around and hit the switch (the skull that has red eyes). Now drop down to the
    floor below you. Down here, step through the teleporter BEHIND the chair and
    you'll be taken onto a platform with a Megasphere and an Invincibility Sphere.
    Talk about a nice combo. You'll get credit for a secret for being teleported.
    
    6. From secret 5, pick up the Yellow Key across from you and you'll be in a
    hall. Once you have the Yellow Key, head up the stairs in front of you. At the
    top, head straight and you'll stop at a wall. The wall to your left is fake, so
    walk into it and you'll be in a hidden room with a Plasma Gun in it. You'll get
    credit for a secret once you step into this room.
    
    7. From secret 6, continue down this hall. Part of the wall to your right is
    fake, so once you find the fake wall, step through it. In this secret area,
    there are health potions and Boxes of Bullets.
    
    -------------------------
    Level 29: The Living End
    -------------------------
    
    Number of Secrets: 0
    
    There are no secrets in this level. Even though there are no secrets in this
    level, you may exit the level with 100% in some source ports, like ZDoom. Have
    a nice day, and there won't be any secrets in the next level.
    
    ----------------------
    Level 30: Icon of Sin
    ----------------------
    
    Number of Secrets: 0
    
    There are no secrets in this level. Even though there are no secrets in this
    level, you may exit the level with 100% in some source ports, like ZDoom. Once
    you beat this level, congrats on beating Doom II.
    
    ----------------------
    Level 31: Wolfenstein
    ----------------------
    
    Number of Secrets: 4
    
    Note that in earlier versions of Doom II, there were no secrets. But in Doom II
    1.9, you can get a score of 100% secrets here. Here are the secrets.
    
    1. Once you start this level, open the door in front of you and go through it.
    In here, open the door to your left and go through it. Down this hall, open the
    door and you'll be in a big room. In here, open the door to the right. Now, go
    through the opening to your right and follow this hallway to a door. Once you
    get to it, open it and go through it. You'll now be in a room with a lot of
    openings. Go into the far opening to the right. In here, open the hidden door
    and go through it. There is a BFG, Megasphere, and a Super Shotgun in this
    secret area.
    
    2. From secret 1, progress the game all the way until you get to the room with
    the exit door. In here, put your back on the door and turn right. The door in
    front of you is a hidden door, so open it and step through. In this small room,
    there is a Medikit. Walk through it to get credit for a secret.
    
    3. While you are in secret 2, turn right and press Spacebar on the walls until
    you find a hidden door. You'll be in a slightly bigger room. The secret exit
    door is just across from you, but step into this room to get credit for a
    secret.
    
    4. Just before you head to the secret exit, face the exit door and turn left.
    Search the walls until you find a hidden door. Once you find it, it will open,
    revealing a Soul Sphere. Pick up the Soul Sphere to get credit for a secret.
    
    -----------------
    Level 32: Grosse
    -----------------
    
    Number of Secrets: 6
    
    Note that in earlier versions of Doom II, there were no secrets. But in Doom II
    1.9, you can get a score of 100% secrets here. Here are the secrets.
    
    1. From the starts of the level, open the door in front of you and go through
    it. In here, you'll notice gray, rectangular walls in this room. Press the
    Spacebar on the first one to the left and it will open, revealing 3 Chainguns.
    Step into this area to get credit for a secret.
    
    2. From secret 2, press Spacebar on the rectangular wall directly across from
    this one and it will open, revealing a Megasphere. Pick this Megasphere up to
    get credit for a secret.
    
    3. From secret 2, get to the other end of this room. Now facing the last two
    rectangular walls, press Spacebar on the one to the left and it will open,
    revealing a BFG. Pick it up to get credit for a secret.
    
    4. From secret 3, open the rectangular wall directly across from the one with a
    BFG. It will open, revealing a Super Shotgun and 2 Boxes of Shotgun Shells.
    Pick them up to get credit for a secret.
    
    5. Now face the wall on the west part of this room. You'll see 3 gold plates.
    Press Spacebar on the one in the middle and it will open, revealing a secret
    room. Step through it to get credit for a secret. There are Energy Cells,
    Medikits, and a Plasma Gun in this nice secret.
    
    6. Now go to the east part of the big room. You'll notice 3 gold plates on this
    wall. Again, press Spacebar on the middle plate and it will open, revealing an
    Invincibility Sphere. Pick it up to get credit for a secret.

    13.) Doom II Bugs and Errors
    ----------------------------------------
    This section has all the bugs and errors I've found in Doom II. If I miss any
    tell me.
    
    ------------------------------------------------------------
    Bugs
    ------------------------------------------------------------
    
    1. In level 7: Dead Simple, killing the Mancubi lowers the walls around you,
    revealing Arachnotrons. If there are 2 of them remaining, and you kill both of
    them at the same time, the game expects that both of them were needed to be
    killed to raise the steps to the exit. This causes the steps to be "stacked up"
    and you can not use them to get to the exit. To get past this, use the switches
    to lower the northeast/west the Mancubi were on. Get where the pillars were,
    and face the platform where the exit switch is on. Now, *run* to it (facing the
    corner of the platform), and you should be on it. Now smack the exit switch.
    The best way to avoid this is to kill the Arachnotrons one at a time, not right
    after each other. If you play the game on Nightmare difficulty, the
    Arachnotrons will keep respawning, so each one you kill will make a wall rise
    around the exit switch.
    
    2. In the old DOS version of Doom II, the game would crash if you saved your
    game when an Arch-Vile was attacking you and you loaded it up again. Thanks to
    Mike C for this one.
    
    ------------------------------------------------------------
    Map Errors
    ------------------------------------------------------------
    
    1. In Level 12: The Factory, you'll notice that you need the Yellow Key to open
    the door that leads into the room with the 5 switches to open up the exit
    teleporter. But when you try to exit this room you will get a message saying
    that you need a Red Key to open the door. But there is no Red Key in the whole
    level and that there is only a Blue and Yellow Key. The only way you can get a
    Red Key is by cheating. Once you enter that room, you cannot leave it.
    
    2. In Level 15: The Industrial Zone, you can only get a maximum secret score of
    90%. This is because one of the secrets was put right on the middle of a
    teleporter, and a play cannot get credit for that secret before being
    teleported away without cheating. To get to this teleporter, open the Yellow
    Door. You'll see a staircase to your left. There are Shotgun Shells on one
    step, and that's where the hidden door is. Open it where the Shotgun Shells are
    to find a teleporter. If you want credit for a secret, use IDCLIP to walk over
    the teleporter.
    
    3. In Level 27: Monster Condo, you can only get a maximum secret score of 87%.
    This is because one of the secrets was put right on the middle of a teleporter,
    and a play cannot get credit for that secret before being teleported away
    without cheating. This teleporter is located at the end of the secret hall with
    all of the health potions in it. If you want credit for this secret, use IDCLIP
    to walk over the teleporter.
    
    4. In Level 27: Monster Condo, an item score of 100% is impossible. This is
    because there are two Computer Area Maps in this level, as they do count
    towards your item score. No problem, right? If there are multiple Computer Area
    Maps in a level, you can only pick up one, then it becomes impossible to pick
    up another. These Computer Area Maps are located in the secret areas near the
    Blue Key.
    
    --------------------------------------------------------------------------------
    
    14.) TNT/Evilution Walkthrough
    ----------------------------------------
    Now, here's the walkthrough (note that this walkthrough is not useful for skill
    level 5)! Also some enemies I tell you to kill in this game may not be there
    because of the skill level so if you don't see an enemy I told you to kill in
    this guide, then you're playing a low skill level.
    
    TNT starts out hard and tricky, but I think it gets easier as it goes.
    
    ------------------------
    Level 1: System Control
    ------------------------
    
    Once you start the first level of TNT, pick up the Berserk pack in front of
    you. Now open the door in front of you and go through it. In here, either kill
    all of the Former Humans with your powered up Fist or use your Pistol. Once
    they're
    all dead, head up the stairs to your right. At the top, kill the Imp and then
    pick up the Armor. Now head back down the stairs. Down here, open the door in
    front of you and go through it. In here, kill the Former Humans and the Imps.
    Now
    you'll see two pillars. Each of them has a switch. Facing the door, hit the
    switch on the left pillar and a wall to your left will open, revealing a
    Stimpack, a Combat Armor, and a few Imps. Kill the Imps and get the items. Now
    hit
    the right switch and leave this room. Back in here, open the small door next to
    you and go through it. Out here, kill the Imps and then get the Shotgun, and
    then leave this room.
    
    Back in here, follow the hallway to your right to another room. In here, kill
    the Imps, Former Humans, and Demons. Now hit the switch in this room and pick up
    the Stimpack to create a staircase in this room. Now head up it. At the top,
    kill the remaining enemies and then follow this pathway to the Blue Door. As
    you walk up to it, you'll hear the sound of a door opening. Turn around and
    you'll see a new opening, so go through it. Out here, kill the Imps and then
    hit the switch. Now head back up the stairs and then leave this room. Back in
    here, head down the stairs in front of you and follow this hallway to another
    room. Back in here, get the Blue Key, kill the Former Commandos and get their
    Chainguns and the Medikits, and then go back into the same hallway. Back in
    here, head back up the staircase and open the Blue Door and go through it.
    
    In here, hit the switch in front of you and the floor you're on will lower.
    Down here, collect the armor bonuses and kill the Former Human Sergeants. Now
    hit the
    switch to open the bars. Kill the Imps and Former Commandos. Walk up to the
    exit switch and you'll see the two pillars lower. Collect the Chaingun on both
    of them and then go on to hit the exit switch.
    
    -------------------
    Level 2: Human BBQ
    -------------------
    
    Start this level by killing the Former Human Sergeant and all of the Imps in
    front of
    you. Once they are all dead, head for the stone wall at the other end of this
    room. Lower this wall by pressing the Spacebar, and then go through the new
    opening. In here, turn left and follow this hallway until you get to the Red
    Key, killing all of the Former Human Sergeants and Former Commandos that are in
    your
    way. Once you get to the Red Key, pick it up. Now drop back down to the floor
    below you. Down here, turn right and go through the opening to be outside. Out
    here, head down the stairs to your left and kill the Former Commando at the
    bottom. After that, kill all of the Former Human Sergeants, Former Humans,
    Imps, and Heavy
    Weapon Dudes in this room, including the ones on the outer ledges. Once they
    are all dead, put your back on the stairs and follow this wall until you get to
    the Red Door.
    
    Once you get to the Red Door, open it and go through it. In here, follow this
    hallway to a staircase and then head down it. At the bottom, you'll be in
    another big room. Kill all of the Imps and Former Commandos on the outer
    platforms again so they won't annoy you later. Now get the Backpack in the
    middle of the room. Head right past the staircase. Over here, kill the Imps and
    Former Human Sergeants around you, and then turn left and hit the switch. Head
    back to
    the staircase in this room, killing the Demon, Cacodemons, and even that
    annoying Pain Elemental that are being release. Once you get to the stairs,
    head up them. Back up here, kill the Demons and the Spectres and then leave
    this room. Back out here, turn left and head back up the stairs at the other
    end of this room. Up here, go through the opening to the right.
    
    In here, go through the opening across from you and save your game. Back up and
    RUN through the window to get on a staircase. On here, head up the stairs. At
    the top, turn right and follow this walkway to a Yellow Key. Once you get to
    the Yellow Key, pick it up. Then kill the Imp to your left and go through the
    opening. Collect the Computer Area Map in here. Now turn around. See that
    window you just ran through? From here, save your game, and then RUN straight
    into the window, to get back up into this room the easy way (instead of going
    all the way around). Back in here, turn right and head up the stairs. As you
    head up the stairs, you'll see the Yellow Door, so open it and go through it.
    Out on these ledges, follow them until you get to the exit door, killing the
    Former Commandos and Former Human Sergeants you see. Once you get to the exit
    door,
    save your game.
    
    RUN into the window to the left. In here, kill the Former Commandos and press
    Spacebar on the walls until you find a hidden door. It will open, revealing a
    Combat Armor, so pick it up. Now turn around and RUN back onto the ledge to your
    left. Back on here, open the exit door to your left and it will reveal a
    Revenant. Kill it, pick up the Medikit, and then hit the exit switch.
    
    -----------------------
    Level 3: Power Control
    -----------------------
    
    Once you start this level, open the door in front of you and go through it. In
    here, kill the Former Human Sergeant in front of you and then follow either
    pathway to
    the opening at the other end of this room. Face the opening and turn around,
    where you'll see a switch. Hit it and the wall will open, revealing a Spectre
    and a teleporter. Kill the Spectre and step through the teleporter. In here,
    kill the Former Human, Imp, Former Human Sergeant, and the Former Commando in
    this room.
    Now open the door in this room and go through it. In this hallway, turn left
    and you will see a door to your right. Open this door and then go through it.
    Out here, head up the stairs to your right, killing the Spectre and the Shotgun
    Guy. At the top, step through the teleporter in front of you. In here, walk
    forward to get the Red Key. Now walk backward to land on the same teleporter.
    
    Back on here, turn around and you'll see two walls with blue symbols on them.
    The one on the left is a hidden door, so open it and it will reveal a hidden
    room with a Medikit and an Energy Cell Pack. Pick up both of them and then
    leave this secret room, walking over the teleporter. From here, head down the
    stairs in front of you. Back down here, go through the opening to your right.
    Out here, kill all Former Human Sergeants, Former Commandos, Spectres, and
    Cacodemons.
    Once they are all dead, collect the Super Shotgun in this room and go through
    the opening in the north part of this room. In here, open the Red Door in front
    of you and go through it. In here, head right and you'll stop at a wall. Kill
    the Imps and Spectres, and then open the door to your left and go through it.
    
    In here, kill the Demons and the Lost Souls across from you. Now turn around
    and face the door. To the right of it is a switch, so hit the switch. Now turn
    around and head straight and stop at a wall. Cross the ledge to the left that
    is against the wall. At the other side, get the Yellow Key. Once you have the
    Yellow Key, leave this room, killing the Imp, Former Human Sergeant, and
    Revenant. Back
    in this hallway, open the Yellow Door and go through it. Back out here, walk
    forward and go through the opening in the east part of room. In here, open the
    Yellow Door in front of you and go through it. In this room, kill the Lost
    Souls, Former Human Sergeants, and the Former Commandos. Now get the Blue Key
    at the
    other end of this room. Once you have the Blue Key, leave this room, ignoring
    the Arch-Vile. Back in here, go through the opening in the south part of this
    room.
    
    Over here, open the Blue Door in front of you and go through it. In here, kill
    the Revenant and kill all of the Mancubi. Once they are all dead, open the exit

    ------------------
    Level 4: Wormhole
    ------------------
    
    This level can either be short or long, depending on if you want to get all of
    the secret areas or not. But for now, start this level by killing all of the
    Former Human Sergeants in front of you. Once they're all dead, collect all of
    their
    Shotguns and then head towards the middle pillar in this room that has the
    Rocket Launcher on it. Press the Spacebar to lower it and pick it up. But
    beware that this lowers another wall with more Former Commandos. Pick up the
    Rocket Launcher and blast them all away. Once they're all dead, pick up their
    Chainguns and then get the health potions that they were in front of as well.
    Now go back to the level's starting point, with your back on the starting door.
    Go through the opening to your right. In here, head up the stairs in front of
    you, killing the Former Human Sergeants, Former Commandos, and Spectres. At the
    top,
    open the door to your left and go through it.
    
    In here, kill the Revenant in front of you. Now walk forward until the floor
    you're on lowers. Down here, wait for the floor you're on to rise again. Back
    up here, turn around and open the same door again. Back on this staircase, head
    down it and go through the opening to your left. In here, hit the exit switch.
    It was either that or go through the rest of this big level.
    
    ----------------
    Level 5: Hanger
    ----------------
    
    You will start the level facing the Red Door, which is also the exit door. You
    will also be seeing a black wall to the right of the Red Door. Walk up to this
    wall and a wall behind you will open, revealing a Former Human Sergeant. Kill
    it and walk
    into the new room, and then you'll hear the sound of another door opening. Turn
    around and you'll see the new room. Kill this Former Human Sergeant and then
    walk into
    the new room. Again, you'll hear another door open. Turn around and you'll see
    a new opening to the left. Kill the Former Human Sergeant and walk into this
    new room.
    Two doors will be opened (one in front of you), revealing an Imp in front of
    you and a Former Human Sergeant behind you. Kill both of them and then enter
    the room
    where the Former Human Sergeant is. Walk forward to here another door open.
    That was the
    last one. Turn around and head left.
    
    From here, kill the Former Human Sergeant and the Imp in front of you. Now head
    up the
    stairs and you'll come across a staircase to the left and right. Head up either
    one of them. At the top of either one, kill the Imp and then open the door in
    front of you and go through it. In here, kill the Imps and walk down the
    staircase below you. The wall in front of you will open, revealing a much
    bigger area, with Former Human Sergeants and Former Commandos on the outer
    walls. To
    close this wall for now, hit the switch on the pedestal to the right. Now Kill
    the Imps, and then open the door to your left and go through it. In here, head
    down the stairs next to you. At the bottom, kill the Imp next to you and head
    up the stairs to the left. As you are heading up the stairs, you'll see an
    opening to the right. Face the opening and turn around. The wall in front of
    you is a hidden door, so open it and get the Box of Shotgun Shells and the
    Armor.
    
    Now continue to go up the stairs. At the top, follow the hallway until you get
    to an opening. Once you get to an opening, go through it. In here, kill the
    Imps and Former Commandos before you even do anything. Now put your back on
    the opening in this room. Across from you is a gray tile on the wall. Press the
    Spacebar on this tile and then back up to the lowered platform in the middle of
    the room. Pick up the Energy Cell and the platform in front of you will lower,
    so get on it and get the Blue Key. Before leaving this room, you'll notice a
    blue wall in front of you. This is a door, so open it and it will reveal a
    Former Human Sergeant and two health potions. Kill the Former Human Sergeant
    and grab both of them.
    Now follow the path to the right to a Super Shotgun, killing the next Shotgun
    Guy. Pick up the Super Shotgun and then leave this hall. Back in here, kill the
    Former Commandos and then leave this room.
    
    Back in this hallway, follow it back to the same staircase and head to the
    bottom of it. At the bottom, head up the stairs next to you. At the top, open
    the door and go through it. Back in here, head up the stairs to the right. At
    the top, open either door in front of you and go through it. Back in here, head
    down the staircase. At the bottom, head down the staircase next to you and
    you'll be back in the level's starting point. Back down here, open the door to
    your left and go through it. In here, kill the Imps, get the ammo and health,
    and then open the Blue Door in front of you and go through it. In this hallway,
    turn left and follow the left hand wall until you get to the Yellow Key,
    killing the Imp, Former Human Sergeant, and Former Commando in this hall. Once
    you get
    to the Yellow Key, pick it up and then leave this room. Back in here, open the
    door in front of you and go through it. Back in here, turn right and head up
    either staircase again.
    
    At the top, open the door in front of you and go through it. In here, head down
    the staircase. At the bottom, you'll see a wall in front of you. This is a
    door, so open it and go through it. Out here, kill all of the Heavy Weapon
    Dudes and the Former Human Sergeants around you before they annoy you later.
    Once they
    are all dead, go to the Yellow Door in the corner of this room, and then open
    it and go through it. In here, step through the teleporter. Once you are
    teleported, go right until you get to the Red Key, killing the Heavy Weapon
    Dudes and blowing up the barrels in your way. Once you get to the Red Key, pick
    it up and drop down to the floor to your left. Down here, open the door across
    from you and go through it. Back in here, head up the stairs in front of you.
    At the top, open either door in front of you and go through it. Back in the
    level's starting point, go to the Red Door, and then open it. In here, hit the

    floor to exit the level. Now before you start the next level, you get a little
    story:
    
    ------------------------------------------------------------
    You've fought your way out of the infested experimental labs. It seams that UAC
    had once again gulped it down. With their high turnover, it must be hard for
    poor old UAC to buy corporate health insurance nowadays... Ahead lies the
    Military Complex. Now swarming with diseased horrors hot to get their teeth
    into you. The Complex still has some warlike ordnance laying around.
    ------------------------------------------------------------
    
    ----------------
    Level 7: Prison
    ----------------

    up
    either staircase in this room. At the top, a wall next to you will lower,
    revealing Pain Elementals, Former Human Sergeants, and Hell Knights. Kill all
    of them and
    then RUN over the pillar and step onto the teleporter. Once you are teleported,
    head all the way left and you will stop at a lava pit. From here, go all the
    way left until you get to a set of teleporters surrounded by barrels, killing
    the Former Human Sergeants, Former Commandos, Spectres, Cacodemons, and the
    Mancubus in
    this area if you need to. Once you get to the teleporter, step into it and

    Former Human Sergeants, and Former Commandos around you. Once they're all dead,
    hit the
    switch to the left and then go through the opening behind the switch. Out here,
    walk left and you'll hear the sound of a lift dropping. Quickly go back inside
    the previous room and you'll notice that the pillar with the Soul Sphere has
    lowered, so pick up the Soul Sphere. Now go back through the opening and drop
    down to the ground below you.
    
    Down here, head left to the lava pit and you'll see a new bridge being raised
    to the center platform. Cross the bridge. On this platform, walk straight and
    you'll get to a box with a switch on one side. Face the switch but do not hit
    it. First, look at this little map below.
    
                 X
          _______S__
         |          |
         |          |
         |          |
         |__________|

    it and ride it to the top. Up here, get the Invincibility Sphere and then step
    through the teleporter. Once you are teleported, hit the switch next to you and
    the floor you're on will lower. Down here, eliminate ALL of the Imps, Hell
    Knights, and Barons of Hell that are in the cages before they annoy you while

    of the room. You'll find a flashing wall, so open it and you'll be in a small
    room with a switch. Hit the switch and get out of here. Now RUN to the opposite

    teleported, open the Red Door in front of you and go through it. In here, kill
    all of the Former Humans, Imps, Former Human Sergeants, Hell Knights, Spectres,
    and Heavy
    Weapon Dudes. Once they are all dead, put your back on the Red Door and go all
    the way straight until you stop at a wall. Once you do, turn left and drop into
    the lava pit below you. Down here, you'll notice three pillars. The pillar in
    the middle has yellow lights on it. Look for a black spot on this pillar and
    then press Spacebar on it, which will open a secret door on the platform above
    you. To get back up there, step through the teleporter next to you. Now go all
    the way right into the new opening, kill the Baron of Hell and get the
    Soul Sphere. Now facing the Red Door from where you are, drop down into the lava
    pit to your left. Down here, go all the way straight and you'll stop at a
    pillar. Press the Spacebar to lower this pillar and then you'll see a switch
    next to you.
    
    Hit this switch and then get on the pillar. Wait for it to rise and then get

    follow this wall until you get to a teleporter. Once you get to a teleporter,

    leave this room. From here, open the door to your right and go through it. In
    here, head up the stairs to your left, killing the Former Human Sergeants and
    Heavy
    Weapon Dudes. At the top, look towards the left wall and you'll find a switch
    with red lights. You'll need the Red Key, but you have it, so hit the switch.
    Now turn around and you'll see a blue wall to the left. This is a lift, so
    lower it, get on it, and ride it to the top. Up here, get the Armor and the
    Medikit, and then drop back down to the floor below you.
    
    From here, head down the stairs in this room. Down here, head left and follow
    this hallway until you stop at a set of silver bars. Press Spacebar to lower
    them and then go into the opening. In here, kill the Imps and Former Human
    Sergeants and
    then hit the switch to your right. A door will open next to you, so go through
    it. In here, kill the Imps, Former Human Sergeants, and Former Commandos. Now go
    through the opening at the other end of the room. In here, kill the Imp and
    Former Commando on the crate. Facing the left crate, you'll see a little
    opening between two crates and there is a barrel at the end. Blow up this
    barrel, otherwise it will block you from getting the Blue Key. Now, get on the
    slightly higher crate, and then RUN onto the higher crate. On here, drop down
    to the floor below you. Down here, go through the opening to your left. In
    here, open the door to your left and go through it.
    
    Now to start an annoying part. In this room, open door after door after door
    until you see a staircase to the left, killing each enemy that you'll see when
    you open each door. Once you see the staircase, head up it, killing the Imps,
    Former Human Sergeants, and Former Commandos that flood this staircase. At the
    top, RUN
    onto the crate to your left (you wouldn't be able to get on here if you didn't
    blow up the barrel). On here, pick up the Blue Key and then drop down to the
    floor to your right. Down here, go through the opening to your right. In here,
    go through the opening at the other end of the room. Back in this room, you'll
    see a switch on the center wall. Hit it and it will open, revealing a Shotgun
    Guy and another switch. Hit this switch and a wall behind you will open, so go
    through it. In here, kill the Former Commandos and Former Human Sergeants. Now
    open the
    door to your right and go through it.
    
    In here, you'll notice a ledge to your right and your left. Get on the right
    ledge. Kill the Former Humans, Former Human Sergeants, and Former Commandos.
    Now get onto
    the ledge to the right. On here, walk forward until you find lights flashing
    green and red. This is a hidden door, so open it and go through it. In here,
    get the Stimpack and the Box of Shotgun Shells. Now turn around and get on the
    ledge in front of you. On here, go into the opening to your right and the floor
    you're on will lower. Down here, hit the switch and then get back on the lift,
    and then ride it to the top again. Back up here, use either ledge to get to the
    door across from you. Now open the door in front of you and go through it. Back
    in here, go through the opening to the left. In this room, open the Blue Door
    to your left and go through it. In here, head down the stairs in this room.
    
    Down here, open the door in front of you and go through it. In this room, kill
    all of the Imps, Former Human Sergeants, and Former Commandos. After that, get
    all the
    health, armor, and ammo on the tables. The ammo ranges from Boxes of Bullets to
    Boxes of Rockets. Once you have everything possible, head up the stairs in this
    room. At the top, kill all of the Imps, Former Human Sergeants, and Former
    Commandos in
    this room. Once they are all dead, open the exit door in this room and go
    through it. In here, hit the exit switch and get out of this crazy level.
    
    ---------------------
    Level 10: Redemption
    ---------------------
    
    Once you start this level, kill the Former Humans in front of you and pick of
    their
    Clips. Now kill the Imp and the Former Human Sergeant at the other end of this
    area. Get
    to the door in this room. Before opening it, get the Box of Shotgun Shells to
    your left. Now open the door and go through it. In here, kill the Imps and
    Former Human Sergeants in front of you. Now get the Super Shotgun and walk
    forward. A
    window will open to your left, revealing Imps, Former Human Sergeants, and
    Heavy Weapon
    Dudes. Kill all of them and then kill the Hell Knight in this room. Once they
    are all dead, hit the switch in this room to open the door next to you. In
    here, lower the lift in front of you, kill the Former Commando, get on it,
    and ride it to the top. Up here, open the door next to you and go through it.
    In here, get the Combat Armor in the middle of the room and a wall to your left
    will open, revealing Imps, so kill all of them. Now get the Boxes of Bullets
    and Medikits, and then turn around and hit the switch.
    
    Once you do all of that, drop down to the floor below you. Back down here, kill
    the Mancubus, Demon, Former Human Sergeants, and the Former Commandos that have
    appeared here. Once they are all dead, head up the stairs in front of you. At
    the top, go through the opening next to you. In here, turn right and follow
    this hallway until you stop at a set of red bars, killing the Demons in this
    hallway. Once you get to the red bars, head down the stairs to your right. Down
    here, get the Plasma Gun and kill the Arachnotrons. Once they're both dead,
    head up either staircase in this room. At the top, hit the switch on the
    pedestal. Now turn around and go up the opposite staircase, and then hit the
    switch on this pedestal, collecting the Energy Cell Pack. Once you hit both
    switches, head up the new stairs in this room. At the top, collect the Yellow
    Key. Now Imps and a Baron of Hell will teleport into this room.
    
    Kill all of them and then kill the Cacodemons, Demons, Pain Elementals, and
    Revenants in this room. Once they are all dead, head up the stairs and leave
    this room. At the top, open the Yellow Door in front of you and go through it.
    In here, head down either staircase to your left or right and you'll be in a
    bigger area. Down here, get the Red Key at the other end of the room that is on
    the pillar. Once you have the Red Key, kill the Spectres, Mancubi, Revenants,
    Former Commandos, and Former Human Sergeants in this room. Once they are all
    dead, head
    up the stairs in this room and leave this room. Back in this hallway, turn
    right and follow this hallway until you see an opening to your left. Once you
    see the opening, go through it and you'll be back at the levels starting
    point. Back in here, drop down to the floor below you and kill all of the Heavy
    Weapon Dudes. Now, open the door in this room and go through it. In here, hit
    the switch to open the door, go through it, lower the lift, get on it, and ride
    it to the top.
    
    Up here, open the door next to you and go through it. In here, open the Red
    Door across from you and go through it. In this hallway, head down the stairs
    and follow the left hand wall until you get to the exit door, killing the Hell
    Knight you'll see. Once you get to the exit door, open it and go through it. In
    here, kill the Imp and then hit the exit switch.
    
    ---------------------------
    Level 11: Storage Facility
    ---------------------------
    
    Once you start this level, pick up the Shotgun Shells and the Shotgun in front
    of you. Now go through the opening to your right. Out here, go through the
    opening through the fence to your left. Now go all the way right through the
    two fence openings, killing the Imps or Former Human Sergeants that annoy you.
    Once you
    get past the fences, head all the way left until you stop at a wall. Now turn
    left and you'll see three doors on the left wall. Open the first one and go
    through it, killing any Imps that annoy you. Now you'll be in the storage area.
    In here, follow the right hand wall until you get to an opening. Once you get
    to an opening, go through it. In this small hallway, press Spacebar on the
    walls to your right until you find a hidden door, and then go through it. In
    here, blow up the barrels and then lower the lift in front of you. Once you
    lower the lift, leave this room, RUN up the stairs to the right, turn right and
    RUN UP THE STAIRS IN FRONT OF YOU. At the top, go through the opening to your
    right.
    
    In here, you should see an opening to your left with a Former Commando, so go
    through it. If the door closes, go back to the opening, lower the same lift,
    and then RUN BACK UP HERE. In here, get the hidden Megasphere. Now leave this
    room and go back right. Back in this huge area, RUN over the gap and get onto
    the crates in front of you. On here, get the Blue Key. Now, on this crate, use
    the smaller crates to get onto a higher set of crates. Up here, RUN over the
    gap and you'll be in front of a Red Door. Kill the Former Human Sergeants and
    then drop
    down to the lower crate to your left. Down here, kill the Former Human
    Sergeants and go
    straight until you see the Blue Door to your right. Once you see the Blue Door,
    open it and go through it. In here, RUN across the crates to the other end of
    the room, killing the Former Human Sergeants too. Once you get to the exit
    door, open it
    and go through it. In here, kill the Former Human Sergeants, get the Shotguns,
    get the
    Stimpacks, and then hit the exit switch. Now before you start the next level,
    you'll get a little story.
    
    ------------------------------------------------------------
    You hear the grinding of Heavy Machinery ahead. You sure hope they're not
    stamping out new Hellspawn, but you're ready to ream out a whole herd if you
    have to. They might be planning a blood feast, but you feel about as mean as
    two thousand maniacs packed into one mad killer. You don't plan to go down
    easy.
    ------------------------------------------------------------
    
    -----------------
    Level 12: Crater
    -----------------
    
    Once you start this level, get the Shotgun, and then open the door in front of
    you and go through it. In this big area, kill all of the Former Humans, Imps,
    Former Human Sergeants, and Former Commandos in front of you. Once they are all
    dead,
    go all the way straight until you see a door to your right. Once you see the
    door to your right, open it and go through it. In here, get the Blue Key at the
    other end of this room. Once you have the Blue Key, kill the Mancubus and all
    of the Demons that appear. Now get the armor and ammo in this room, and then
    leave this room. Back in here, go straight into the opening. Now follow the
    right hand wall until you get to the Blue Door. Once you get to the Blue Door,
    open it and go through it. In here, head down the stairs in front of you. Down
    here, go all the way straight to the Rocket Launcher and then pick it up. Now
    go all the way left and you'll be outside. Out here, go through the opening
    that is directly across from you.
    
    In here, head up the stairs to your left, killing the Spectre on the stairs. At
    the top, kill the Baron of Hell. Now get the Red Key across from you. Once you
    have the Red Key, drop down to the floor to your left. Back down here, go back
    through the large opening in the east part of this room. In here, follow this
    hallway until you get to a set of stairs, and then head up them. Back up here,
    go through the opening to your left. In here, follow this pathway until you get
    to the Red Door, killing the Imps and Former Commandos. Once you get to the
    Red Door, open it and go through it. In here, hit the switch to your right and
    the floor you're on will lower. Down here, kill the Former Commando and then
    follow the left hand wall to an opening. Once you get to the opening, just go
    all the way straight to the blue and silver wall, killing any Former Humans you
    see. Once you get to the blue/silver wall, press the Spacebar to lower it and
    it will reveal an Arch-Vile, so kill it.
    
    Once the Arch-Vile is dead, lower the wall, get on it, and ride it to the top.
    Up here, get the Armor and Shotgun Shells to your right. Now turn around, grab
    onto the Berserk and then hit the switch. The floor behind you will lower, so
    fall down it. Back down here, head left into the room. In here, head up the
    stairs at the other end of the room. At the top, kill the Arachnotrons and then
    hit the exit switch once both of them are dead.
    
    ----------------------------
    Level 13: Nukage Processing
    ----------------------------
    
    Once you start this level, turn left. You'll see a barrel in front of a light
    gray wall. Blow up this barrel and then press Spacebar on the light gray wall.
    It will open, so go through it. In here, go through the first opening to your
    right. Kill the Former Human Sergeant in here and then press Spacebar on the
    wall in
    front of you. It will open, so get the hidden Backpack. Now get the health, and
    kill the rest of the Former Human Sergeants and Former Commandos in this room.
    Once you
    have done all of that, leave this room and go back to the level's starting
    point. Back in here, press Spacebar on the crate in front of you and it will
    lower, revealing an opening so go through it. You just took the shortcut to get
    outside. Out here, go all the way straight to the other end of this room,
    killing the Imps, Demons, Revenants, and Mancubi in this area. Once you get to
    the other end of the room, you'll find a little building. Open the door on it
    and go through it.
    
    In here, kill the Revenant and then pick up the Yellow Key. Now get the Medikit
    and Box of Rockets, and then leave this room. Back out here, follow the right
    hand wall until you get to a door, killing any leftover enemies in this area.
    Once you get to the door, open it and go through it. In this area, kill the
    Mancubus, Imps, Former Human Sergeants, and Former Commandos. Once they're all
    dead,
    walk to the middle of the room. Now go right and you'll get to a lift, so lower
    it, get on it, and ride it to the top. Up here, open the Yellow Door in front
    of you and go through it. In here, go straight and kill all of the Former Humans
    and Former Human Sergeants. Once they are all dead, head up the stairs to the
    left. At
    the top, kill the Former Human Sergeants and then follow this pathway to a
    bigger area.
    Over here, you'll find two switches. Hit the switch across from the door and a
    pillar to your left will open, revealing a Pain Elemental and the Red Key.
    
    Kill the Pain Elemental and then RUN onto the top of the pillar. On here, get
    the Red Key and then drop down to the floor below you. Back down here, head
    back up the stairs. Up here, follow this pathway to the same door. Next to it
    is a switch. Hit it and it will open, so go through it. In here, step through
    the teleporter and you'll be taken to a hallway. In this hallway, kill all of
    the Former Human Sergeants and Former Commandos. Now follow the right hand wall
    until
    you notice that one of the walls has a different design. This is a hidden door,
    so open it and go through it. In here, kill all of the Imps and then get the
    Combat Armor. Now leave this room. Back in here, turn right and follow this
    hallway until you get to a teleporter. Once you get to a teleporter, step
    through it. On this platform, turn left. You'll see a platform with a Blue Key
    on it, so RUN onto it and pick up the Blue Key. Now drop down to the floor
    below you. Back down here, you'll notice a pillar lowering to the left. There
    is a Cyberdemon there on Ultra Violence, but ignore it.
    
    Instead, open the door across from you and go through it. In here, lower the
    lift across from you, get on it, and ride it to the top. Up here, open the Blue
    Door in front of you and go through it. In here, kill all the Imps and Heavy
    Weapon Dudes. Now get to the exit door at the other end of this room. Once you
    get to it, hit the switch next to it to open it. Now go through it. In here,
    lower the lift in front of you, get on it, and ride it to the top. Up here,
    kill the Former Human Sergeant in front of you.
    
    ----------------------
    Level 14: Steel Works
    ----------------------
    
    Once you start this level, run all the way straight and you'll stop at a wall.
    Now turn right and you'll see the hardest key to get in the whole game. :) The
    Yellow Key is right there, so pick it up. Now turn around and kill all of the
    Former Humans behind you. Once they are all dead, kill the Former Human
    Sergeants and then
    get to the other side of this room. Over here, go through the opening to the
    left. In here is a door, but to open it, hit the switch to the right. Now go
    through the opened door. In here, kill all of the Former Humans and then get to
    the
    other side of this room. Over here is a door to your right, so open it and go
    through it. In here, kill the Former Humans and then follow this hallway to
    another
    door. Once you get to the door, open it and go through it. In here, kill all of
    the Former Humans in this room. Now open the Yellow Door at the other end of
    this
    room and go through it. In here, head up the stairs to your right.
    
    At the top, kill all of the Former Humans to your left. Once they are all dead,
    go
    through the opening to your left. In here, head up the stairs, killing the
    Former Human Sergeant and the Former Commando in this staircase. At the top of
    this
    staircase, go through the opening to your left. In here, follow this hallway to
    a staircase. Once you get to the staircase, kill the Former Human Sergeant and
    all of the
    Former Humans on the staircase, and then head down the stairs. Down here, kill
    all
    of the Demons and Former Humans in this room. Once they are all dead, put your
    back
    on the staircase and turn right. You'll see a lift leading to a higher
    platform, so lower it, get on it, and ride it to the top. Up here, RUN all the
    way straight to the opening across from you before you get killed by the toxic
    floor. Once you get to the opening, go through it. In here, drop down to the
    ground below you. Down here, get the Medikits to your left and then turn
    around. Now go through the opening in front of you. In here, follow this
    hallway until you get to the Blue Key, killing the Imps and Spectres in this
    hallway.
    
    Once you get to the Blue Key, pick it up. Now turn around and follow this
    hallway back to the previous room. Back in this room, lower the lift to your
    left, get on it, and ride it to the top. Up here, the ceiling above you is now
    a crushing ceiling, so RUN all the way to the other side of this platform. Over
    here, drop back down to the floor below you. Back down here, head right and
    you'll see a lift surrounded by blue bars. Now that you have the Blue Key, hit
    the switch to the left of the blue bars and then the bars will be removed. Now
    lower the lift, get on it, and ride it to the top. Up here, run to the other
    side of this platform before the toxic floor kills you, and once you do get to
    the other side of this platform, the ceiling above you will turn into a
    crushing ceiling. Now drop down to the floor below you. Down here, kill all of
    the Former Humans and then turn right. You'll see an opening to your left, so go
    through it. In here, head up the stairs to your right. At the top, go through
    the opening to your right.
    
    In here, kill all of the Lost Souls and then try to work your way around all of
    these pillars to get to the other side of this room. Once you do get to the end
    of this room, hit the switch and it will open like a door, so go through it. In
    here, follow this hallway until you get to an opening, killing the Former
    Humans in
    this hallway. Once you get to the opening, go through it. In here, get the Red
    Key at the other side of this room. Once you have the Red Key, turn around and
    you'll see a wall lower to your right. Kill all of the Former Human Sergeants
    and Heavy
    Weapon Dudes, and then get the Radiation Suit in that room. Now leave this room
    and go back into the hallway. Back in here, follow this hall back to the door
    and then open it. Back in this room, get around all of the pillars again, but
    the thing is now that it's completely dark in this room. Once you get to the
    other end of the room, go through the opening. Back in this room, head down the
    stairs to your left.
    
    Down here, lower the lift next to you, get on it, and ride it to the top. Up
    here, RUN to the other side of this platform before the crushing ceiling kills
    you. Once you get to the other side, drop down to the floor below you. Down
    here, head up the stairs at the other side of the room, ignoring all of the
    enemies. Up here, follow this hallway until you see an opening to your right.
    Once you see the opening, go through it. In here, head down the stairs, killing
    the Former Human Sergeants and the Former Commando in this hallway. At the
    bottom of
    the stairs, go through the opening to your right. In here, head down the
    stairs. At the bottom, open the Red Door and go through it. Back in this room,
    open the door across from you and go through it. In here, follow this hallway
    to a door. Once you get to the door, open it and then go through it. Back in
    here, get to the door at the other side of this room. Hit the switch to open it
    and then go through the door.
    
    Now you'll be back at the level's starting point. If you're playing on Ultra
    Violence, there is a Spider Mastermind here. Try to ignore it and get to the
    other side of this room. Over here is a switch. Hit it to remove the Red Bars
    blocking the exit teleporter, and then step on the exit teleporter.
    
    --------------------
    Level 15: Dead Zone
    --------------------
    
    When you start the level, get all the ammo and armor in this room, then from
    where you started, press the Spacebar in front of the wall to your right. It
    will then open like a door, so go through. Out here, get to the wall across
    from you, head right, following along with the wall until you see a silver wall
    (the one you're following is gray). The silver wall is a lift. Press the
    Spacebar to lower it, so get on it, and ride it to the top.
    
    Up here, head up the stairs in front of you. Up here, go through the opening to
    the right. In here, see that switch on the left wall? Remember where it is.
    Now, see that opening across from you? Go into it. You should be on a
    "balcony". Get to the edge of it and you will see a BFG on a pillar. Remember
    where the switch was? Go back, save your game hit it, and *RUN* back to the
    balcony, jump off, and get the BFG while it's lowered. Otherwise, load your
    saved game and try again. Down here, head up the stairs across from you. At the
    top, go straight and you will be in a room with toxic sludge in it. Turn right.
    See that "Poison" symbol on the wall to the right? Press the Spacebar in front
    of it to open it, revealing a Backpack.
    
    Grab the Backpack and turn back around. Now head up the stairs to the left. At
    the top, there are two doors across from you. Enter either one, and you'll be
    in the same room. In here, get the Box of Shotgun Shells, open the door in
    front of you, and go through it. In here, go through the opening at the other
    end of the room. In here, follow the right hand wall to a Plasma Gun. Once you
    get to the Plasma Gun, pick it up and turn around. Press the Spacebar on all of
    the walls in front of you until one of the walls open, revealing a Berserk.
    Grab it and then open the hidden door to the right in this small room. In here,
    step on the teleporter. Now turn around. Hit the exit switch (this takes you to
    the secret exit ;)).
    
    Now, before you enter the next level, you get a story:
    ------------------------------------------------------------
    What now? Looks totally different. Kind of like King Tut's Condo. Well,
    whatever's here can't be any worse than usual. Can it? Or maybe it's best to
    let sleeping gods lie...
    ------------------------------------------------------------
    
    ------------------
    Level 31: Pharaoh
    ------------------
    
    !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    Note that there is a huge bug in this level that stops you from getting the
    Yellow Key. For more information, see my Bugs and Errors section. To get the
    bug fix, go to www.teamtnt.com and click "Bugs and Fixes" and it will be there.
    This walkthrough covers all 3 keys and getting to the exit using the bug fix.
    If you would like to use the walkthrough without the path, use my walkthrough
    at the "Alternate Pharaoh Walkthrough" section.
    !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    
    Once you start the level, kill all the Former Human Sergeants in front of you
    and pick up
    all of their Shotguns. Now turn right and kill all of the Former Humans on the
    pyramid. Once that is done, look around this room and you will see two switches
    on rectangular walls. Hit each switch and the walls will lower, revealing all
    the health, ammo, and weapons you could possibly want, having a Super Shotgun,
    Chaingun, Rocket Launcher, and Plasma Gun, and there ammo for it. Once that is
    done, look for an opening to the left of the pyramid. Once you see it, go
    through it. In here, kill the Former Commando and hit the switch on the wall
    hanging from the ceiling. Once you do that, leave this room. Back out here, go
    into the pyramid and through the opening.
    
    Now this looks like a real Egyptian level! Across from you is an opening.
    Before going into the opening, kill the Imps to your left and right. Now, go
    through the opening at the other end of this room. In here, drop down to the
    floor below you. Down here, hit the switch on the wall and a staircase will be
    created back to the opening, so head back up the stairs. Back in here, get to
    the opening at the other end of the room. There are Arachnotrons to your left
    and right, but they are not able to attack you yet. Facing the opening, turn
    left and you will see an opening, so go through it. In here, head down the
    stairs in front of you. At the bottom, go through the opening at the other end
    of the room. In here, head down the stairs and you will get to a basement.
    
    Down here there are pillars in this room. One of them on the higher floor has a
    switch, so find that pillar. Once you find the switch, hit it. Now, before
    leaving this room, kill all the Hell Knights and Revenants in here so they
    won't annoy you later on. Now leave this room and head back up the stairs. Back
    in here, head through the opening at the other end of the room. In here, head
    up the stairs in front of you, killing all the Spectres in your way. At the
    top, go through the opening in front of you. Back in this room, 2 of the
    Arachnotrons have been released. Kill them and go through the new opening at
    the other end of the room (from the opening you were just at). Over here there
    is a staircase, so head up it. At the top, step through the teleporter in front
    of you.
    
    You will be teleported into a dark hallway with many twists and turns. Work
    your way to the other side of the room and you should be able to see a lighter
    room, killing all of the Spectres in your way. Once you can see the bright
    room, go through it. In here, the Yellow Key will be to the right if you are
    using the TNT31.WAD. If not, you're not using the patch. Pick up the Yellow Key
    and leave this room. Back in here, follow this hallway to the teleporter. Once
    you get to the teleporter, step back through it. Back out here, drop down to
    the floor below you. Down here, two more Arachnotrons have been released, so
    kill them. Now, go through the opening to your left. In here, drop down to the
    floor below you. Down here, open the Yellow Door to your right and it will
    reveal a switch, so hit it.
    
    Once you hit the switch, turn around and head back up the stairs to your left.
    Back up here, go through the opening at the other end of the room. In here,
    walk straight and leave the pyramid. Back at the level's starting point, go
    through the new teleporter in the southeast part of this room. You will be
    teleported to another part of the level. In here, kill the Revenants on the
    pool to your left and then head up the spiral staircase to your left. At the
    top, kill all the Former Human Sergeants and Mancubi. Once they are all dead,
    turn around
    and face the pool with the Soul Sphere on it. To the right is a switch on the
    wall, so hit the switch. Now, once you hit the switch, back up and you will hit
    a wall. Face the pool, and then RUN to it and you should get on it. On here,
    get the Soul Sphere and drop down to the floor below you.
    
    Down here, go through the opening in the east part of this room. In here, turn
    left and you will see a switch to your left. Hit it and then turn around. You
    will see two more switches at the other end of the room. Before hitting them,
    Arch-Viles will be released, so kill them before they cause trouble. Now, get
    to both switches and hit them both. Once you do that, turn around and face the
    opening. You will see a new pedestal to the right and left of the opening. Get
    in front of either pedestal, and then hit the Spacebar on it. It will be
    activated like a switch, so hit the Spacebar on the other pedestal to hit
    another switch. Now leave this room. Back in here, head up the spiral staircase
    at the other end of the room.
    
    Up here, turn right and follow this pathway to an opening. When you get to an
    opening, go through it. In here, drop down to the floor below you. Down here,
    follow this hallway to a switch. When you get to a switch, hit it and turn
    around. Follow this hallway until you stop at a wall. Now hit the switch to
    your left and the floor you're on will rise. Back up here, drop down to the
    floor to your left. Down here, turn left with the stairs to your back. Now, go
    through the new opening to the left. In here, follow this long hallway until
    you see a red torch on the wall. Once you get to the red torch, stop in front
    of it and turn right. The wall in front of you is fake, so go through it and
    get the hidden Combat Armor. Now leave this secret room.
    
    Back in here, follow this hallway until you see a staircase to your right. Once
    you see the staircase, head up it. At the top, walk forward and a pillar will
    raise in front of you, revealing a Blue Key. To the right of that is another
    wall lowering, which is a lift. Once it is done lowering, kill the Pain
    Elementals across from you. Once them and the Lost Souls are all dead, save
    your game. Now, hit the switch to your right and then turn left, facing the
    lift. You'll notice part of the wall will lower and then raise, and that is the
    lift. Hit the switch, RUN left to the lift, get on it, and ride it to the top.
    Up here, turn left and you will be facing the platform with the Blue Key on it.
    Run onto the platform and grab the Blue Key.
    
    Now, drop down to the floor below you and RUN to the opening at the other end
    of the room. Before you are able to leave the pyramid, and Arch-Vile will
    teleport right in front of your face. Blast the hell out of it with a Plasma
    Gun or a BFG, and when it's dead, turn around and kill the other Arch-Vile
    before it revives all of the Arachnotrons. Now, once both of them are dead,
    leave the pyramid by going through the same opening. Back out here, open the
    Blue Doors in the southwest corner of this room and they will reveal a
    teleporter, so step through it. In this large room, kill all of the Mancubi.
    After they are all dead, kill all of the Revenants on the higher platforms.
    Once you do all of that, you will see a switch on a rectangular wall. Hit it
    and it will lower, revealing ammo and health.
    
    Grab all of what you see and then hit the switch on the other wall and it will
    lower, revealing more health and ammo. Now, head up the stairs leading to the
    building. At the top, open the door in front of you and go through it. In here,
    hit the switch in front of you, and then leave this building. Back out here,
    turn left and you will see a square wall lowering, revealing a pillar, stairs,
    the Red Key, and Arachnotrons. Kill all of the Arachnotrons and then head up
    the stairs around the pillar. At the top, get the Red Key. Now, face the easy
    part of this room and you should see a pedestal rising revealing a switch. Hit
    it and the walls surrounding you will lower, revealing Former Humans and
    Cacodemons. Kill all of them. Once they are all dead, face the pedestal with
    the switch on it and turn right.
    
    There is a wall to your left. Follow it until you get to a switch. Once you get
    to a switch, hit it. Now, keep following this wall until you get to another
    switch (if you don't see one, there should be a wall lowering revealing another
    switch). Once you see the switch, hit it. Now, turn right and step through the
    teleporter at the northeast part of this room. You'll be teleported back to the
    level's starting point. Back in here, save your game and go into the pyramid
    again. In here, there should be a platform across from you. If you're playing
    on Ultra Violence, there should be a Cyberdemon on it. Try your best to ignore
    it and then go through the opening at the other end of the room. In here, don't
    open the Red Door yet. Instead, you will notice a chair to your left and right.
    Remember these. Now, open the Red Door and it will reveal a switch.
    
    Hit the switch and turn around. The chair in front of you has lowered,
    revealing another switch. Hit it and turn left. A door will be opened, so go
    through it. In here, go all the way straight to the staircase at the other end
    of the room, and then head up it. At the top, the wall in front of you will
    open, revealing a Megasphere. Pick it up and hit the switch in front of you.
    Now turn around, go through the opening to your right, and hit the switch to
    your right. Back in here, kill any Former Human Sergeants teleporting in front
    of you,
    and then go through the opening in front of you. In here, wait for the wall in
    front of you to lower, and then head up the stairs in front of you. At the top,
    walk straight and drop down to the water below you. Down here, you will see a
    pit to your left. Now turn right you will see an arch surrounding a wall. This
    wall is secret, so walk up to it and it will lower, revealing a room with a
    load of health and armor bonuses.
    
    Collect all of them and then get to the wall at the other end of this room.
    Press spacebar on it and it will lower, revealing a switch. Hit it and you will
    be taken to the secret exit.
    
    Now, before you enter the next level, you get a little story.
    
    ------------------------------------------------------------
    Time for a vacation. You've burst the bowels of Hell and by golly you're ready
    for a break. You mutter to yourself, maybe someone else can kick Hell's ass
    next time around. Ahead lies a quiet town, with peaceful flowing water, quaint
    buildings, and presumably no Hellspawn. As you step off the transport, you hear
    the stomp of a Cyberdemon's Iron Shoe.
    ------------------------------------------------------------
    
    --------------------
    Level 32: Carribean
    --------------------
    
    Once you start this long and boring level, hit the switch in front of you and
    the floor you're on will lower onto a walkway. On here, get the Shotgun and the
    Boxes of Shotgun Shells next to you. Now follow either pathway until you get to
    another pathway. Once you get to the other pathway, cross it. At the end,
    you'll notice there is a piece of wood designed slightly different from all the
    others. This is a door, so open it and go through it. In here, kill the Heavy
    Weapon Dudes to your left and right. Now head straight and you'll see an
    opening to your right and left. Go left and you'll stop at a wall. QUICKLY turn
    around and you'll see a wall lower to your right. A Baron of Hell will come out
    of it, but ignore it and GET THE SOUL SPHERE IN THE ROOM THAT LOWERED. If not,
    there's no way to lower it again.
    
    Anyway, go back to the door, and this time take the opening to the right. In
    here, head straight and you'll see a staircase to your left, so head up it. At
    the top, follow this hallway until you get to a bigger room. There is a
    Soul Sphere in the middle of the room. It can be lowered, but save it for later.
    Instead, go through the opening across from you. In here, pick up the Rocket
    Launcher and hit the switch. The wall in front of you will lower, so kill all
    of the Former Human Sergeants teleporting into this room. The Soul Sphere has
    now lowered,
    so if the Former Human Sergeants roughed you up big time, now's the time to get
    it. Go
    back to the switch you just hit. Hit the switch on the OTHER SIDE of this
    switch. A lift to your left and right will lower. Get on either one and ride it
    to the top. Kill the Former Commando at the top and hit the switch. Now drop
    back down to the floor, hit the switch, and go on the other lowered lift. Kill
    the Former Commando up here and hit the switch.
    
    Once you have hit both switches, drop down to the floor below you. Down here,
    head left/right (depending on which lift you came down from) and go straight to
    the other end of the room. Over here is an opening, so go through it. Back in
    here, follow this hallway back to the staircase, killing the Former Humans,
    Demons,
    and Revenants that have appeared. Once you get back to the staircase, head down
    it. Down here, kill all of the Revenants next to you and then pick up the Blue
    Key and all of the goodies around it. Once you have the Blue Key, go through
    the opening next to you (the one with the gray walls). In here, kill all of the
    Former Human Sergeants in front of you and head down the stairs. At the bottom,
    go
    through the opening to your right. In here, pick up the Plasma Gun and the
    Yellow Key and the floor you're on will lower. Down here, walk forward and
    destroy all of the other barrels so you won't get killed. This should kill the
    Arachnotron and Arch-Vile in this room as well.
    
    When they are both dead, lower the lift at the other side of this room, get on
    it, and ride it to the top. Up here, drop down to the water below you. Down
    here, go all the way right and you'll get to the Blue Door. To open this door,
    hit the switch next to the door and it will open, so go through it. In here,
    get the Box of Rockets, hit the switch, and then leave this room. Back out
    here, a pathway will be rising in front of you. To get to it, head up the
    stairs to the left to get back on this pathway. Now turn right and follow this
    pathway until you get to it, watching out for the Former Human Sergeants and
    Heavy Weapon
    Dudes that teleport into here. Once you get to the pathway, cross it. At the
    end of the pathway, a door will open to your right, revealing Mancubi, so kill
    all of them. Now go to where the door opened and hit the switch in that area.
    This switch opens a door to the left, so go through it.
    
    In here, kill the Pain Elementals and then drop down to the floor to your
    right. Down here, open the door in this pit and go through it. In here, follow
    the left hand wall until you get to a bigger room. Once you get to a bigger
    room, kill the Former Commandos and hit the switch in this room. Now leave
    this room. Back in here, follow the right hand wall until you get to a set of
    barrels. Next to the barrels is an opening to the right, so go through it. In
    here, walk right and the wall in front of you will open, revealing a Baron of
    Hell and a Spectre. Kill them both and hit the switch on the wall. Now leave
    this room. Back in here, follow the left hand wall until you get to another
    opening. In this opening is an Arch-Vile, Spectres, and Former Commandos.
    Kill all of them and go into the opening. In here, hit the switch and then
    leave this room. Back in here, open the door to your right. Yay! We finally got
    the hell out of there!
    
    Back in this room, head up the stairs in front of you. At the top, drop down to
    the floor below you. Down here, go through the opened door. In here, follow the
    pathway to another big room. In here, kill the Hell Knights, Revenants, Heavy
    Weapon Dudes, and the Mancubus. Once they're all dead, hit the switch and then
    get back on the pathway. Back on here, you'll notice a wall lowering with the
    Red Key on it. Pick up the Red Key, kill the Imps and Pain Elementals, and then
    leave this room. Back in here, head up the stairs in front of you. At the top,
    head right and leave this room. Back out here, turn left or right and follow
    the pathway until you get to a Red Door. Once you get to the Red Door, open it
    and go through it. Out here, head up the stairs across from you. At the top,
    look forward and you'll see two openings. Go through either opening and head up
    the stairs. At the top, go straight and hit the switch on the wall next to you.
    Now head down either staircase and go back through the opening.
    
    Back out here, a wall has lowered, revealing a Cyberdemon (or Spider Mastermind
    on easier skill levels), Hell Knights, Revenants, and Mancubi. Kill all of them
    and then go into the new opening. You'll see a demon face on the wall to the
    left. Kill the Arch-Vile behind it before it pisses you off. Now leave this
    room and go back outside. Back out here, drop down into the pit below you. This
    is an annoying part. You'll see a silver teleporter and a red teleporter. Step
    through the silver one first. When you teleport, hit the switch next to you and
    step back into the teleporter next to you. Now hit the switch next to the red
    teleporter and step through the red teleporter. If you were quick enough,
    you'll see the exit switch, otherwise both doors will shut. If not, you'll need
    to hit both switches to open both doors. Once you are quick enough, go into the
    opening and hit the exit switch.
    
    FINALLY I AM DONE WITH THAT LEVEL, I THOUGHT I WOULD NEVER FINISH IT!
    
    --------------------------
    Level 16: Deepest Reaches
    --------------------------
    
    Once you start this level, kill the Imp and the Former Human Sergeant in front
    of you.
    Now open the door in front of you and go through it. Out here, kill the Imps,
    Former Human Sergeants, Former Commandos, and the Cacodemons in front of you.
    Once they
    are all dead, turn left, with the pit to your right. If you look left, you
    should see one wall brighter than all of the others. This is a hidden door, so
    open it and go through it. Get the Box of Bullets in this secret area and then
    turn around. See the pit across from you? Use all of the platforms to RUN
    across the pit. At the end of the pit, get the Super Shotgun, and then go
    through the opening in front of you. In here, kill the Demons and the Shotgun
    Guy. You'll notice a door to your right and your left. Open the door to the
    right first and go through it. In here, head up the stairs in front of you. At
    the top, go through that opening leading to a box shaped structure to your
    right.
    
    In here, pick up the Box of Rockets and the Medikit. You'll also notice a blue
    switch on the wall, so hit this switch. Now head left and head up the stairs to
    a higher platform. At the top, kill the Mancubus, Former Human Sergeants,
    Revenant,
    Former Humans, Imps, and the Former Commandos. Once they are all dead, search
    this area for a switch. Once you find the switch, hit it. Now head right and
    follow this pathway until you stop at a pedestal. On this pedestal is a Rocket
    Launcher/BFG, depending on whatever skill level you're playing on. Pick it up
    and drop down to the floor to your right. Down here, head left and go through
    the opening across from you. In here, head down the stairs in front of you,
    killing the Former Commando. Down here, go through the opening to your left.
    In here, head down the stairs in front of you. At the bottom, kill the
    Mancubus, Imps, and Former Human Sergeants. Once they are all dead, follow the
    right hand
    wall to a teleporter. Once you get to a teleporter, step through it.
    
    When you teleport, you'll see a Blue Key in front of you, so pick it up. Now
    here's a trick that can be easily overlooked. When you teleport into this room,
    there is a teleporter still behind you. Just back up into it to be teleported,
    and you will be taken near the pit at the start of the level. This saves a lot
    of time and is much better than backtracking, so step through this teleporter.
    Once you teleport, open the door directly in front of you and go through it. In
    here, walk straight to the other end of the room and the floor you're on will
    lower. Down here, you'll see a switch to your right. Hit this switch to open
    the door next to you, and then go through it. In here, head down the staircase
    to the left. At the bottom, kill the Imps, Cacodemons, Lost Souls, and Hell
    Knights. Once they are all dead, open the Blue Door in this area and go through
    it. In here, head up the stairs in front of you. At the top, turn left and go
    through the opening to your left. In here, kill all of the Former Humans and
    Imps.
    Once they are all dead, go through the opening across from you.
    
    In here, follow the right hand wall, but notice carefully at the walls. When
    you get to a pink wall that is designed differently from the red walls, you'll
    know it's a lift, so lower it, get on it, and ride it to the top. Up here, turn
    right and follow the left hand wall until you get to the Yellow Key, killing
    the Demons and the Former Human Sergeants up here. Once you get to the Yellow
    Key, pick
    it up. Now turn back around, get back to the lift, and drop back down to the
    floor below you. Back down here, turn right and follow the left hand wall to an
    opening. Once you get to it, go through it. Back in here, go through the
    opening across from you and you'll be outside again. Back out here, head right
    and head down the stairs across from you. At the bottom, open the door in front
    of you and go through it. In here, head up the stairs to your right. At the
    top, you'll get to the door, so open it and go through it. In here, hit the
    switch to the right to lower the lift, get on it, and ride it back to the top.
    Back up here, open the door across from you and go through it.
    
    Now you're near the starting area again (near the pit). Open the door to your
    left and go through it. Back in this room, head up the stairs. At the top, go
    through the opening to your left and head down the stairs. Down here, go
    through the opening to your left and head down the stairs. At the bottom, head
    straight and then turn left. You'll get to the Yellow Door, so open it and go
    through it. In here, head down the stairs to your right. Down here, use either
    walkway to get to the door at the other end of the room, killing the Shotgun
    Guys and Imps on this walkway. Once you get to the other end of this room, open
    the door and go through it. In here, step through the teleporter. When you
    teleport, hit the switch in front of you and stairs will be created to your
    left so head down them and get the Box of Shotgun Shells. Down here, hit the
    exit switch.
    
    --------------------------
    Level 17: Processing Area
    --------------------------
    
    Before you start this level, turn around and you'll see a door. Open it and
    pick up the Invisibility Sphere. Now turn back around and kill the two Shotgun
    Guys. Once they are both dead, open the big door out here and go through it. In
    here, go through the opening to the right, killing the Imps and Former Human
    Sergeants in
    this room. In here, go all the way straight until you see a staircase to your
    left, killing the Imps in this hallway. Once you see the staircase, head up it.
    At the top, kill the Former Commandos, get the Box of Bullets, and then pick
    up the Yellow Key. Once you have the Yellow Key, head back down the same
    staircase you used to get to this room. Back down here, open the Yellow Door in
    front of you and go through it. In here, follow this walkway to another door,
    killing the Former Human Sergeants and the Arch-Vile in this area. Once you get
    to a
    door, open it and go through it. In here, kill the two Revenants and then hit
    the switch to the left. Now once you hit the switch, leave this room. Back in
    this room, use the new pathway to get to the Blue Key in the center of the
    room.
    
    Once you have the Blue Key, turn around and open the door to your right. Now go
    through it. Back in this hallway, go all the way left until you see a staircase
    to your right. Once you see the staircase, head up it. At the top, go through
    the opening in front of you. In here, open the Blue Door in front of you and go
    through it. In here, head up either staircase in front of you. At the top, grab
    all of the ammo, kill the Former Human Sergeants, and then pick up the Red Key
    at the end
    of this room. Once you have the Red Key, turn around and QUICKLY leave this
    room before all sorts of enemies start teleporting into this room. If they give
    you enough of a problem, just grab the Invincibility Sphere next to where the
    Red Key was. Once you leave this room, you'll see a staircase to your left or
    right. Choose the right staircase, but just go halfway down the staircase. See
    the wall on your left? Get next to it and hold up, and you SHOULD BE ABLE to
    get onto that ledge. Once you get onto it, turn left.
    
    You'll see a Combat Armor on a pillar. RUN to this pillar. To get the Combat
    Armor,
    press the Spacebar to lower the first platform, and then hit the Spacebar again
    to lower the pillar with the Combat Armor. Now pick it up and turn right, where
    you'll see the door. Walk up to the door and turn right. Now you should see a
    set of Red Bars across from you. Go up to them, killing the Former Commando.
    Now once you get to the Red Bars, press the Spacebar on them and they will be
    removed, revealing the exit switch, so hit it.
    
    ---------------
    Level 18: Mill
    ---------------
    
    Once you start this level, drop down to the floor in front of you. Down here,
    open the door in front of you and go through it. In this hallway, kill all of
    the Former Human Sergeants in front of you. Once they are all dead, go straight
    until you
    see a staircase to your right. Once you see the staircase, head down it. Down
    here, kill all of the Arachnotrons and Pain Elementals on this floor, and then
    kill the Former Human Sergeants on the higher platforms in this room. Once they
    are all
    dead, collect the Medikits in this pit, and then head up the stairs in the east
    part of this room. At the top, follow the pathway into an opening. Once you get
    to the opening, go through it. In here, kill the Former Human, get the Box of
    Rockets and then hit the switch in this room. Now leave this room. Back out
    here, drop down to the floor below you. Down here, go into the new opening to
    the right. The 4 doors leading to this building will all shut. Hit the switch
    in this room and an Arch-Vile will teleport, so kill it.
    
    Now with the switch hit and the Arch-Vile is dead now, notice the wall lowering
    in the southeastern corner of this room. Wait for it to lower completely. Once
    it has lowered, step onto it and you will be teleported onto the Blue Key. Pick
    up the Blue Key and then drop down into the pit below you. Back down here, head
    up the stairs in the middle of the room to exit this room. Back up here, turn
    left and you'll see an opening to the left of the door across from you, so go
    into this opening. In here, follow this hallway until you see a staircase to
    your left, killing the Spectres in this hallway. Once you see the staircase,
    head up it. At the top, get the Box of Shotgun Shells and then head down the
    stairs in front of you. In this room, kill the Barons of Hell and the Revenants
    in this room. Once they are all dead, open the door to your right and go
    through it. In here, kill the Arch-Vile and then hit the switch in front of
    you. This will open a door to your right, so go through it. Hit the switch at
    the end of this hallway. Now turn back around and leave this room.
    
    Back in this area, you can now get the Red Key across from you, so pick it up.
    Once you have the Red Key, head up the staircase in this room. At the top, head
    down the staircase in front of you. Back down here, turn right and follow this
    hallway until you see an opening to your right. Once you see the opening, go
    through it. In here, open the Red Door in front of you and go through it. In
    here, head straight to the other end of this room. At the end of the room is a
    switch. Hit this switch and a number of lifts will lower in this room. The lift
    you need to go on is the one on the wall to your right. Get on this lift and
    ride it to the top. Up here, go through the opening across from you. In this
    room, turn left and go through the opening to the left. In here, hit the switch
    and it will lower a lift behind you. Kill the Barons of Hell on the lift, get
    on it, and then ride it to the top. Up here, hit the switch in front of you.
    Now drop back down to the floor below you.
    
    Down here, head all the way straight to the end of this hallway. When you stop
    at a wall, hit the switch in this area and a lift behind you will lower. Kill
    the Barons of Hell, get on the lift, and ride it to the top. Up here, hit the
    switch to your left and then turn back around. Now drop down to the floor below
    you. Back down here, open the Blue Door to your right and go through it. In
    here, open the Blue Door across from you and go through it. On this side of the
    hallway, go through the opening across from you. In here, lower the lift, get
    on it, and ride it to the top. Now turn around and face the opening in this
    room. You'll see a face on the wall to the left and right. Take out a
    Pistol/either Shotgun or a Chaingun and SHOOT the face on your left. This will
    cause the platform you're on to rise. Up here, hit the switch. Now turn around
    and drop back down to the floor below you. Down here, go through the opening
    across from you. Back in this hallway, head right and you'll stop at a lift.
    
    Lower this lift, but do not get on it. Instead, hit the switch to the left
    before the bars rise and block the switch (in that case just lower the lift
    again). Once you have this switch hit, head left and go through the opening to
    your right. In this room, hit all 4 switches on the pillar in the center of the
    room (if bars are blocking a switch, look back in this area for a switch you
    haven't hit). Once you have all switches hit, go through the opening in the
    east part of this room. In this hallway, go through the opening in front of
    you. In here, walk straight until you see the Yellow Key to your left. Once you
    see the Yellow Key, pick it up. Now continue straight into a small opening, and
    then go through it. The floor you're on will lower, and you'll be near the Red
    Door. Down here, kill the Demon and go through the opening to your left. In
    here, kill the Former Commandos to your left and right, and then walk in
    front of the Red Door. You can't open this Red Door by yourself, but to open
    it, hit the switch to the left. Now go through the opened door.
    
    In here, go through the opening in front of you and you'll be back in the
    center hallway. Now turn right and follow this hallway until you get to an
    opening. Once you get to an opening, go through it. In here, hit the switch
    across from you. The switch will lower a lift to your left, so get on it and
    ride it to the top. Up here, follow the hallway to a Yellow Door. Once you get
    to the Yellow Door, open it and go through it. In here, get to the northwest
    part of this room using your Automap (cross the pathway in the middle of the
    room as well). Over here, look for a small opening that has a different
    designed wall. Shoot this wall with a Pistol/either Shotgun/Chaingun, or use
    your Fist/Chainsaw. Once you shoot this, head to the southeast corner of this
    room. Near the Yellow Door, look for an opening filled with dead marines
    inside, and then go through it. In here, hit the switch and then head do the
    center of the room. Cacodemons, Hell Knights, Former Human Sergeants, Former
    Commandos
    will all teleport into this room. Even a Cyberdemon will enter this room (on
    harder skill levels). Have all the enemies weaken or kill the Cyberdemon, and
    if he's still alive, finish him off.
    
    Once he's dead, go through the new opening in the northern part of this room.
    In head, head straight and step on the exit teleporter.
    
    ------------------------------
    Level 19: Shipping/Respawning
    ------------------------------
    
    Once you start this level, open the door in front of you and go through it. In
    here, kill the Revenant and then get the Shotgun and Box of Shotgun Shells. Now
    open the door in this room and go through it. In this hallway, turn left and
    follow the left hand wall until you stop at a door, killing the Former Human
    Sergeants
    and Former Commandos in this hallway. Once you stop at a door, turn right and
    you'll see a blinking light on the floor and ceiling. The wall that is blinking
    is a hidden lift, so lower it, get on it, and ride it to the top. Up here, pick
    up the Soul Sphere and then drop back down to the floor below you. Back down
    here, open the door next to you and go through it. In here, open the door
    across from you and go through it. In this room, drop down to the floor below
    you.
    
    Down here, get to the opening across from you, killing the Former Human
    Sergeants in this
    hall. When you get to the opening, go through it. In here, open the door at the
    other end of this room and then go through it. In here, kill the Hell Knight
    and the Former Commandos and then head up the staircase to your right. At the
    top, kill all of the Imps in this room. Now open the door across from you and
    go through it. In here, kill the Imps, the Former Commandos, and the
    Mancubus. Once they are all dead, notice this ASCII map below.
    
    ----------------------------------------

    |__________________________________/
    
    As usual, let's say the X is you. The small square is a chair and the platform
    above it is a higher platform with a TV. But see that small box that has "YK"
    in it? Walk into this box to get the Yellow Key. This is a very easy key to
    miss and it's easy to overlook it, so I am mentioning it here. Even I had a lot
    of problems finding this key, but I hope this helps you. Now once you hit the
    Yellow Key, hit the switch to the left of the door you came from (in the
    southwest part of this room). This switch will open a door at the northeast
    corner of the room, revealing a teleporter. Run to the northeast corner and
    step into the teleporter. If the door closes, simply hit the switch again to
    reopen the door.
    
    Now, you'll be teleported back into the same hallway near the beginning of the
    level. Follow this hallway to the same door earlier (near the hidden lift), and
    once you get to it, open the door in front of you and go through it. In here,
    open the door across from you and go through it. In here, drop down to the
    floor below you. Back down here, go through the opening across from you. Back
    in this room, open the Yellow Door to your left and go through it. In here, get
    the Blue Key across from you and then Imps and Former Commandos will appear
    near you. Quickly get rid of them before they annoy you. Now leave this room.
    Back in here, open the door to the right and go through it. Back in this room,
    go through the opening across from you. In this hallway, open any of the Blue
    Doors to your right and then go through them. Now this is the shipping area,
    where you see all the crates and such. Wonder what's in them.
    
    Just watch out for the Former Human Sergeants and Former Commandos that roam
    this area
    on the higher crates, because they may get to you and piss you off, so it's
    better off if you save your game before you explore this area. Now get to the
    northeast corner of this room, killing the Imps, Former Human Sergeants, and
    Heavy Weapon
    Dudes. Once you get to the northeast corner, notice the doors on the wall. To
    open these doors, hit the switch to the left of the doors and then go through
    any of them. You'll be outside now. Out here, go into the truck, kill the
    Cacodemons, and get the Red Key. Too bad that truck wouldn't move, otherwise
    there'd be no Red Key here and you'd be stuck in here forever. Now try to exit
    this room before the doors open. If not, drop down to the ground below you and
    go to the southeast corner of this area. Near here is a switch. Hit this switch
    to open up all the doors. Now blow up the barrels to the right and get back on
    the higher platform using the step. Back up here, exit this room before the
    door closes.
    
    Back in here, open the Red Door in the southeast part of this room and go
    through it. In here, kill all of the Former Humans in front of you. Once they
    are
    all dead, follow the right hand wall to the exit door. Once you get to it, open
    it and go through it. In here, kill the Former Commandos and hit the exit
    switch.
    
    -----------------------------
    Level 20: Central Processing
    -----------------------------
    
    Time for a long and annoying level. Start this level by picking up the Super
    Shotgun in front of you. Now kill all three Imps in front of you and then head
    straight to the other end of this room. Over here, turn right and you'll see a
    door across from you. Kill all of the Former Human Sergeants, Imps, and Heavy
    Weapon
    Dudes first. Now open the door across from you and go through it. In here, turn
    left and then search the middle of this room for a teleporter, as it's kind of
    hard to tell where it exactly is. Just work around all of the silver walls in
    the middle of the room until you find one (should be near a Hell Knight),
    killing the Imps and Former Commandos in this area. Once you find the
    teleporter, step through it. In this room, just open the door on the wall to
    your right and go through it. That's all you need to do in this room, and now
    you'll be back in the previous room you were just in. Back in this room, head
    to the east part of this room and look for a new opening.
    
    When you find the opening, go through it. In here, go through the opening to
    your right and a staircase will rise to the platform above you, so head up it.
    At the top, hit the switch to your left and a floor will rise to your left (and
    one will lower as well), revealing a Plasma Gun. Pick it up and then go through
    the opening across from you. In here, you'll notice a lift rising and dropping
    in front of you. Until it drops, kill the Imps and Former Commandos around
    you. Once the lift does drop, get on it and then ride it to the top. Up here,
    head right and step on the blue platform. This will cause a door to open to
    your left, revealing a staircase, a Red Key, Imps and Former Commandos. Kill
    all of the Imps and Former Commandos, and then get the Red Key at the top of
    the staircase. Once you have the Red Key, head to the bottom of the stairs.
    Down here, head down the hallway to your right and you'll see 3 openings. Go
    through the middle opening to be on the safe side.
    
    In here, kill all of the Former Commandos, Former Human Sergeants, and Demons.
    Once
    they are all dead, get the Berserk next to the teleporter and then step through
    the teleporter. You'll be taken back to the start of the level, right where you
    started. Back in here, head straight and then go left instead of right. Over
    here, open the Red Door across from you and go through it. In here, walk up to
    the door to your right, but do not open it. When you walk up to it, a wall
    behind you will open, so go through it. In here, kill the Imp, the Heavy Weapon
    Dude, and the Revenant. When they are all dead, head right and you'll get to a
    switch. Shoot this switch with a Pistol, either Shotgun, or a Chaingun to
    activate it. Now leave this room. Back in here, go through the new opening to
    your left. In here, kill the Imps and the Arachnotron. Once they are dead, go
    through the opening in this room. In here, follow the left hand wall until you
    get to a pit, killing the Former Human Sergeants and Imps in this hallway.
    Before you get
    to the pit, remember to pick up the Radiation Suit along the way.
    
    Once you get to the pit, drop down it. Down here, turn right and kill the
    Demons and Spectres. Once they are all dead, find a door in this room. Before
    you open this door, turn around. If you are playing on skill levels 3, 4, or 5,
    there will be a Blue Key across from you, so pick it up, and then go back to
    the door and open it. If you are playing on skill 1 or 2, the Blue Key is not
    there, so just open the door and go through it (go through it on 3, 4, and 5
    too). In here, head right and kill the Imps. At the end of this hallway is a
    lift, so lower it, get on it, and ride it to the top. Up here, head straight
    into the toxic room. In here, go through the opening across from you. In here,
    get the Invincibility Sphere and then follow this hallway to a door (somehow
    you'll get credit for 2 secrets for doing so). At the end of the hallway is a
    Blue Key on skill levels 1 and 2 (people on skill levels 3, 4, and 5 should
    already have it).
    
    Now open the door in front of you and go through it. In here, open the Blue
    Door across from you and go through it. In here, kill the Revenants and
    Mancubus and take either path to the other end of this room. At the other end
    of this room is a Medikit and a Box of Bullets. Pick up both of them and the
    wall next to you will lower, revealing a Combat Armor. Pick it up and then leave
    this room. Back out here, go through the opening in the northern part of this
    room. In here, shoot the switch with a Pistol, either Shotgun, or a Chaingun to
    open up the door to the left, and then go through it. In here, kill the
    Arachnotrons and the Imps. Now get the Yellow Key at the other end of this
    room. Once you have the Yellow Key, get the Rocket Launcher and the Box of
    Rockets. Now turn around and you'll see a brown wall that is designed different
    from the bricks. This is a Yellow Door, so open it and go through it. In here,
    kill the Imp and then walk forward to be teleported.
    
    Back in this room, open the Yellow Door across from you and go through it. Out
    here, kill the Imp in front of you. You'll also hear a sound of a Spider
    Mastermind when you fire your gun. Uh-oh. Now head straight and drop down to
    the ground below you. Down here, fall into the river in front of you. Down in
    the river, head right into the opening and you will be teleported. Once you
    teleport, kill all of the Imps around you. Now open the door to your left and
    go through it. In here, go into the opening to your right. In here, step
    through the teleporter and you'll be taken onto another platform. On here, drop
    onto the lower platform below you. Down here, get the Soul Sphere and then
    notice the fence surrounding you. Look for a hole in the fence. Once you find
    it, go through the hole and drop down into the water below you. Down here, look
    for a teleporter, killing the Former Commandos, the Arch-Vile, the
    Arachnotron, and maybe even the Spider Mastermind in this pit. Once you find
    the teleporter, step on it.
    
    Once you teleport, head up the stairs right next to you. At the top, head
    straight to the wall across from you. This wall is a lift, so lower it and get
    on it. As the list rises, you'll notice a platform as you go up the lift. Get
    on that platform and do not get on the one at the top. Now you'll be on what I
    call the "10 mile walkway", as you'll be on a really long pathway. From here,
    just RUN right along this walkway until you stop at a wall. If any
    Cacodemons/Pain Elementals/other enemies annoy you, kill them. But once you
    stop at a wall, there should be a fire in the shape of a triangle to the right
    of the wall. Walk up to the wall standing NEXT to the fire to make it lower.
    Now get on this lowered wall and ride it to the top. Up here, kill the Heavy
    Weapon Dude and the Imps on the higher platform to the right. Now, notice the
    fence to the left. There is a torch next to part of a fence. Next to this torch
    is a Box of Bullets and a hole in the fence.
    
    Pick up the Box of Bullets and go through the hole to drop down to the floor
    below you. You'll be on another walkway, but this one is nowhere as long as the
    "10 mile walkway". Turn left and follow this walkway to a teleporter, killing
    the Arachnotrons, the Former Commando and getting the Medikit. Once you get
    to the teleporter, step on it. When you teleport, turn around and you'll see
    "exit" on the wall. Press Spacebar on this wall to exit this level.
    
    Now, before you enter the next level, you get a story:
    ------------------------------------------------------------
    The vista opening ahead looks real damn familiar. Smells familiar, too like --
    fried excrement. You didn't like this place before, and you sure as hell ain't
    planning to like it now. The more you brood on it, the madder you get. Hefting
    your gun, an evil grin trickles on your face. Time to take some names.
    ------------------------------------------------------------
    
    --------------------------------
    Level 21: Administration Center
    --------------------------------
    
    Once you start this level, kill the Imp in front of you. Now get the Super
    Shotgun and the Box of Shotgun Shells and then walk forward. Now fall into the
    pit. Down here, head straight to the center of the room and a pillar will
    lower, revealing plenty of Hell Knights (more than you can deal with). Wipe out
    all of them with a BFG or a Rocket Launcher, and once they are all dead, step
    on the platform in the middle of the room. Get the Berserk, the Boxes of
    Rockets, and the Box of Shotgun Shells on this pillar. A pillar in the western
    part of this room will also lower, revealing a Revenant, a Red Key, and a
    teleporter. Go to that pillar, kill the Revenant, get the Red Key and then step
    through the teleporter. Once you teleport, kill the Former Commando and the
    Hell Knight in this room. Once they are both dead, open the door on the right
    and leave this room.
    
    Back out in this hallway, turn right. Now go all the way straight until you see
    a Red Door to your right, killing the Former Human Sergeants, Imps, and Heavy
    Weapon
    Dudes that may annoy you. Once you see the Red Door to the right, open it and
    go through it. In here, kill the Imps, the Former Commando, and the Hell
    Knight. When they are all dead, look for a desk and a chair in this room. Stand
    on the chair and face the wall with the green vines. This is a door, so open it
    and go through it. In here, look for a black flag in the southwest corner of
    the room. This black flag is a door, so once you find it, open it up and go
    through it. In here, drop down to the floor to your left. Down in this dark
    room, kill the Imps and work your way around the crates to the south part in
    this room. In the south part of this room is a switch. Hit this switch and the
    wall to your right will open, so go through it. In here, kill the Imps, the
    Former Human Sergeant, and the Mancubi. When they are all dead, hit the switch
    in this
    room.
    
    This will open a door to your left, so go through it. In here, kill the Imp,
    Mancubi, and the Former Commando, and then get the Box of Rockets in this
    room. Now leave this room. Back in this room, follow the right hand wall until
    you get to a Box of Rockets. Once you get to a Box of Rockets, pick it up and a
    staircase to your left will be created, so head up it. At the top, open the
    door to your right and go through it. In this room, kill the Heavy Weapon
    Dudes. Now open the door in front of you and go through it. Back in this room,
    drop down to the floor below you. Down here, open the door across from you and
    go through it. In this hallway, turn right and you'll see an opening to your
    right, so go through it. In here, walk straight and fall into the bit below
    you. Back in this pit, you'll notice a pillar has lowered with the Yellow Key
    on it. Kill the new Revenant and pick up the Yellow Key. Once you have the
    Yellow Key, step through the same teleporter you did earlier.
    
    Back in this room, open the door to your left and go through it. In here, turn
    left and follow this hallway until you see a Yellow Door to your left, killing
    the Imps, Former Commandos, and Former Human Sergeants that annoy you. Once you
    find
    the Yellow Door (which should be in northeast part of hallway), open it and go
    through it. In here, kill the Imps and the Hell Knights. Now open the door to
    your left and go through it. In here, save your game before you do anything
    else. Now follow this hallway to a Box of Rockets and then pick it up. The
    floor you're on will lower into a pit. Down here, drop down to the pit below
    you. Now follow the right hand wall to a lift that is rising and dropping. Once
    it drops, quickly get on it, because the floor you're on can kill you. Once you
    get on it, wait for it to start rising. At the top of the lift, kill the Heavy
    Weapon Dudes in this room. Also in this room, get to the black flag at the
    other end of this room. It is a door, so open it and go through it.
    
    In this same hallway, turn right and you'll face the pit, so drop back down
    into it again. Down here, you'll noticed another lowered pillar with the Blue
    Key on it, so pick it up and kill the Revenant. Now step through the teleporter
    at the other end of the room again. Back in this room, open the door to your
    left and go through it. In here, turn left and head all the way straight until
    you see a Blue Door to your left. Once you see the Blue Door, open it and go
    through it. In here, walk up to the wall to the left, and it will open, making
    this whole room dark. Now walk forward to the next wall and it will open,
    revealing a small little gap. Walk across this gap, but do not fall in it (if
    you do, don't worry, it will raise back up to the ground). Once you walk across
    it, turn around and look for a new opening on the wall to the left. Once you
    find it, go through it. In here, shoot the switch in front of you with a
    Pistol, either Shotgun, a Chaingun (or use your Fist/Chainsaw) and a wall in
    front of you will lower, revealing a pillar. Kill the Baron of Hell on this
    pillar and walk up to it.
    
    The pillar will lower, so step on it and you will be teleported. Once you are
    teleported, turn around and fall into the small pit below you. Down here, kill
    the Imps and hit the switch to make this floor rise. Now face the door near you
    and then turn right. Search the walls in front of you until you find a hidden
    door, revealing a Combat Armor and then pick it up. Once you have it, open the
    door next to you and go through it. Out here, kill all of the Imps in front of
    you. Now turn left and follow the right hand wall to a lava river, killing the
    Imps, the Revenants, and the Cyberdemon on hard skill levels if you see him.
    Once you see the lava river, go into it and go into the opening. In here, go
    all the way straight until you get to a Soul Sphere, killing the Arachnotron
    you'll see. Once you get to the Soul Sphere, pick it up and then turn around.
    Now go straight and you'll see a wall lowering across from you, revealing
    another wall. Kill all of the Imps around this wall and then walk around it.
    Once you get to it, it should say "exit" on it. Hit spacebar on any side of
    this wall to exit this level.
    
    ------------------
    Level 22: Habitat
    ------------------
    
    You can go right to the exit, but I recommend that you search for some of these
    neat secrets before you go off doing any of that. Once you start this level,
    turn right and kill the Former Human Sergeants and Former Commandos behind the
    crates.
    Now from where you started the level, turn around and face the wall. You'll
    notice that one part of the wall is slightly curved. To the level of that
    "curve" is a fake wall. Walk through it and you'll be in a hidden area with a
    Soul Sphere. Pick up the Soul Sphere and you'll hear the sound of a lift
    dropping. Leave this area and you'll see a crate lowered to your right. Walk
    over it before it rises (if it does, go back to the Soul Sphere area and try
    again).
    
    Over here, pick up the Shotguns and Chainguns. Now press the Spacebar on the
    same crate to lower it. Hit the switch and then turn around. You'll see a new
    hole in the floor. Drop down to it and you'll be in another secret area. In
    here, walk forward and a staircase will be created, so head up it. At the top,
    kill all of the Imps that appear and then get the Rocket Launcher and the BFG.
    Once you did everything, hit the switch to lower the lift in this room. Now get
    on it and ride it to the top. Back up here, lower the same crate in front of
    you and then walk past it. From here, you'll see a river leading to an opening.
    Follow this "river" to a bigger room. Once you get to it, you'll see a
    staircase and a Plasma Gun to your right.
    
    Get the Plasma Gun and the two Energy Cell Packs; you'll really need them. Now
    head up the stairs. At the top, you'll see doors across from you. Walk up to
    them and they will open. Hell Knights, Barons of Hell, and an Arch-Vile will
    teleport around you. Clean them up with your BFG, and then face the wall in
    this room. It is a fake wall, so walk through it and you'll see a Blue Key. Now
    pick it up and go back to the "river". Back on here, turn left and follow this
    river to a set of green waterfall bars. Instead of going through these, turn
    around and you'll see an opening, so go through it. In here, drop down to the
    big pit below you. Down here, notice that big silver wall in the west part of
    this room. Walk up to the MIDDLE of it and it will lower, revealing an opening.
    This is a big shortcut in the level.
    
    Go through the opening. In here, walk up to the wall in front of you and it
    will lower so get on it and ride it to the top. Up here, collect the Berserk
    and the Invincibility Sphere, and then walls around you will open, revealing
    Spectres. Punch all of them down with your Berserk while you are invincible.
    One they're all dead, go through the opening at the other end of this big area
    (going across the river). In here, step in that big pit to exit the level
    before all of the enemies in this room attack you.

    Level 23: Lunar Mining Project
    -------------------------------
    
    Once you start this level, head straight to the other end of this hallway. At
    the other end of this hallway is a door, so open it and go through it. In here,
    count the 4 doors on the wall across from you. Open the SECOND DOOR TO THE LEFT
    and go through it. In here, kill the Former Human and the Former Human
    Sergeant, and then
    get the Yellow Key in this room. Once you have the Yellow Key, leave this room.
    Back in here, open the door to your right and go through it. In here, kill the
    Former Humans and the Former Human Sergeant, and then open the Yellow Door
    across from you
    and go through it. In this room, head to the opening across from you. Facing
    the opening, there should be a chair to your left. Get on this chair and use it
    to get onto the higher platform above you. On here, pick up the Red Key and
    then drop back down to the floor below you. Down here, go through the opening
    in the northwest corner of this room and the floor you're on will lower.
    
    Down here, lower the lift to your right, get on it, and ride it to the top. Up
    here, go all the way straight to the other end of this walkway, running over
    the gaps, killing the Former Human Sergeant, and getting the Shotgun Shells.
    Once you get
    to the other side of this gap, drop down to the floor below you. Down here,
    kill the Revenant and the Imps, and then get the Blue Key in this room. Once
    you have the Blue Key, turn around and QUICKLY go through the opening across
    from you before enemies start teleporting into this room. In here, run forward
    to the other end of this walkway, running over the gaps you see. At the end,
    drop down to the floor below you. Down here, lower the lift next to you, get on
    it, and ride it to the top. Back up here, open the Yellow Door across from you
    and go through it. In here, open the door across from you and go through it.
    Back in this hallway, you'll see a Red Door and a door to your right. Open the
    normal door and go through it.
    
    Back at the level's starting point, go through the opening to your left. In
    here, open the Blue Door to your left and go through it. In this room, kill the
    Baron of Hell and the Former Commando and then head up the stairs. At the
    top, walk into that moving scenery to exit this level.
    
    -----------------
    Level 24: Quarry
    -----------------
    
    Once you start this level, pick up the Shotgun across from you. Now turn around
    and you'll see an opening, so go through it. In here, walk through the ripped
    openings and you'll be in a bigger room. In here, kill the Spectre and the
    Imps, get the Security Armor, and then go through the opening to your left. In
    here, keep going through the ripped openings until you find yourself outside.
    Out here, get the Medikit to your left and then go through the opening on the
    wall in front of you. Now get the Medikit in the lava and you'll see an opening
    to your left and your right. Go through the opening on the left. In here, go
    into the opening in front of you. In here, turn left and kill the Former Human
    Sergeant.
    Now walk straight and carefully listen for the sound of a lift dropping. Once
    you hear that sound, you should be next to a wall with two brown poles around
    it. Walk through that wall, as it is fake, and get the Radiation Suit. Now
    continue following this hallway to a lowered lift.
    
    If the lift has risen before you get to there, backtrack until you hear the
    sound of a lift dropping again. Now RUN to the lowered lift and step on the
    teleporter. Once you teleport, you'll collect the Blue Key. Now wait for the
    floor you're on to rise. Up here, kill the Revenant, and then get the Rocket
    Launcher and the Box of Rockets. Now fall down this platform on its SOUTH SIDE.
    Down here, you should see a Blue Door to your left. Get the Box of Shotgun
    Shells and RUN over the small gap. Now open the Blue Door and go through it. In
    here, kill the Revenant and pick up the two Medikits. Now collect the health
    and armor bonuses and then hit the exit switch.

    Level 25: Baron's Den
    ----------------------
    
    When you start this level, follow this hallway to an opening, killing the
    Former Human Sergeant in this hallway. Once you get to the opening, go through
    it. In
    this big room, you'll notice a few Imps and a Former Human Sergeant. Kill all
    of them and
    you will notice an opening below you, one to your left, and one to your right.
    Go through the opening to the right. In this hallway, kill the Former Human
    Sergeant and
    go through the opening across from you. In here, kill the Arachnotrons and then
    get the Plasma Gun in the east part of this room. When you have the Plasma Gun,
    go through the opening in the northern part of this room. In here, open the

    pathway. Follow this pathway to an opening. Once you get to the opening, go
    through it. In here, kill the Former Human Sergeants. Now open the door across
    from you
    and go through it.
    
    In here, you'll be in front of a curved staircase. Follow it down until you see
    an opening to the left. Once you see the opening to your left, go through it.
    In here, follow the hallway until you see the opening to your right. Once you
    see this opening, go through it. In here, head down the stairs in front of you.
    At the bottom, there is a wall to your left and right. The wall on the right is
    a fake wall, so go through it. In here, kill the Former Human Sergeants and
    then get the
    Red Key. Now go back to the staircase and head back up it. At the top, head
    right and follow this hallway to an opening. Once you get to it, go through it
    and you'll be back on the staircase. Back on here, head to the bottom of the
    staircase. At the bottom, open the door to your left and go through it. In
    here, kill the Former Human Sergeants and then turn left. Walk up to the pillar
    in the
    middle of the room and it will lower, revealing a teleporter, so step on it.
    When you teleport, kill the Pain Elemental in front of you and then head up the
    stairs to your right. At the top, go through the opening to your right.
    
    In here, open the door in front of you and go through it. In here, kill the
    Former Human Sergeants and then follow this hallway to an opening. When you get
    to the
    opening, go through it. In here, turn left and you'll see an opening to your

    start. Back in this big room, drop down to the pit in front of you. Down here,
    go through the opening to your right. In here, get the Super Shotgun and then
    open the door across from you and go through it. In here, walk up to the wall

    up to the demon face wall to the left and it will open, so go through it. In
    here, open the Red Door in front of you and go through it. In here, kill the
    Mancubi and then get the Blue Key in the middle of the room. Once you have the
    Blue Key, hit the switch in the southern part of this room. A lift to your
    right will slowly lower, so you'll need to be patient. Once it does lower, kill
    the Barons of Hell on it. Now get on the lowered lift.
    
    On here, hit the switch and wait for the lift to rise very slowly again to the
    top. Once it does make it to the top, walk up to the wall in front of you and
    it will open, revealing another area. In here, go through the opening to your
    left. In this dark hallway, walk forward until the floor you're on lowers. When
    it does, just stay where you are and wait for it to rise again. Back up here,
    get to the other end of this room now. At the other end of the room, just go
    through the opening to your left. In here, walk to the demon face and it will
    open, so go through it. In here, kill the Baron of Hell and then hit the switch
    on the wall to the right. This will open up the wall to your left, so go

    to a door, killing the Baron of Hell in this hallway. When you get to the door,
    open it and go through it. Out here, get the Medikits and kill the Barons of
    Hell. Now walk in front of the switch in this room and the floor you're on will
    lower.
    
    Down here, hit the switch now and go into the room in front of you. In here,
    kill the Former Commandos and the Barons of Hell. There should be a
    teleporter in here, so step through it (if not, go back and hit the switch).
    Once you teleport, go through the opening in front of you. In here, hit the
    exit switch to your left.
    
    --------------------
    Level 26: Ballistyx
    --------------------
    
    When you start this level, open the door in front of you and go through it. In
    here, pick up the Super Shotgun in front of you and then walk forward. A door
    in front of you will open, revealing Revenants. They can't get off the platform
    they're on, so just ignore them and head up either curved staircase. At the
    top, go through the opening in front of you. In here, follow this hallway until
    the floor you're lowers. Down here, kill the Spectre and follow this hallway
    until the floor you're on lowers. Down here, follow this hallway until the
    floor you're on lowers. Down here, kill the Spectres and follow this hallway

    you get to a door. When you get to a door, open it and go through it. In here,
    head down the stairs in front of you. Down here, kill all of the Former Human
    Sergeants
    and Imps and then go through the opening at the other end of this room.
    
    In this hallway, follow this to another opening, killing the Former Human
    Sergeants in
    this hallway. When you get to the opening, go through it and then you'll be in
    a bigger area. In here, kill all of the Imps, Former Human Sergeants, and
    Former Humans in
    this room. Now get the Blue Key in the middle of this room. Once you have the
    Blue Key, search for a burning barrel in this room. Once you find the burning
    barrel, press Spacebar on the wall to the left of it and it will open,
    revealing a Soul Sphere and a Light Amplification Visor. Pick them both up and
    then turn around. Go through the opening across from you. Back in this hallway,
    follow it back to the bigger room. Back in here, head up the stairs across from
    you. At the top, open the door in front of you and go through it. In this
    hallway, follow the right hand wall until you get to a staircase, killing the
    Imps and the Hell Knight in this hallway. Once you get to the staircase, head

    this
    hallway. Once you get to the opening, go through it. In here, hit the switch at
    the other end of this room, killing the Imps and Demons in this hallway. Once
    you hit the switch, look for an opening in the pillar in the middle of the
    room. Go through the opening and step through the teleporter. You'll be taken
    next to a Rocket Launcher and the Yellow Key. Pick them both up. When you have
    the Yellow Key, open the door to your left and go through it. In here, step
    through the teleporter. When you are teleported, go through the opening in
    front of you.
    
    Back in this hallway, follow it until you see a door to your right. When you
    see the door, open it and go through it. In here, open the door across from you
    and go through it. Back in this room, head up the stairs to your right. At the
    top, go through the opening in front of you. Back in this hallway, follow the
    right hand wall until you get to a door, killing the Imps, Former Human
    Sergeants, and
    the Hell Knight in here. When you get to a door, open it and go through it. In
    here, head down the staircase in front of you. Down here, go through the
    opening across from you. In this hallway, go through the opening at the other
    end of this room. You'll be back where the Blue Key was. Follow the right hand
    wall until you get to the Yellow Door, killing the Mancubus and Former Human
    Sergeants in

    the opening in the south part of this room. In here, walk forward and a pillar
    behind you will lower, revealing a Mancubus and a Red Key. Kill the Mancubus
    and get the Red Key.
    
    Once you have the Red Key, leave this room. Back in this big area, backtrack
    all the way back to the door we used to get to this part of the map. When you
    get back to the door, open it and go through it. Back in this hallway, turn
    left and follow the left hand wall to a Red Door. Once you get to the Red Door,
    open it and go through it. In here, head down the stairs in front of you. At
    the bottom, kill the Revenants in this area. Now go through the opening to the
    right and you'll be teleported back to the starting area. In front of you is a
    pit of dead marines. Step into this pit to exit the level before the Arch-Vile
    comes and gets ya.
    
    ---------------------
    Level 27: Mount Pain
    ---------------------
    
    Mount Pain: The Name Says It All
    
    My favorite level in all of Doom. And yes, the name does say it all. Huge
    groups of enemies wherever you go. Now start this level by getting the Super
    Shotgun and the Boxes of Shotgun Shells in front of you. Now kill all of the
    Former Human Sergeants and go through the opening to your left. In here, head
    down the
    stairs to your right. Down here, turn left and go all the way straight to the
    other end of this hallway, killing the Imps and getting a Radiation Suit. At
    the other end of this hallway, turn right and you'll see a Medikit. Walk up to
    it and a door to your right will open, so go through it and drop down to the
    floor below you. Down here, go through the opening to your left. In this
    hallway, kill all of the Imps and then follow it to a door. Once you get to the
    door, open it and go through it. In here, get on the lift that is rising and
    dropping (once it does drop). When you get on it, get the Box of Rockets and
    the Box of Shotgun Shells, and then wait for it to rise all the way.
    
    At the top, open the door and go through it. In here, go through the opening to
    your right. In here, kill all the Imps and then go straight. You'll see an
    opening to your left and right. Go through the opening on the left. In here,
    follow this VERY LONG HALLWAY until you see a wall that says "DISASTER AREA" to
    the left, killing all of the Imps in this hallway. Be quick because the floor
    you're on is poisonous (don't worry, there is a Radiation Suit somewhere in
    this hallway). Once you see the wall that says "DISASTER AREA", get in front of
    it. It is a door, so open it and go through it. In this large room, walk in
    front of the Security Armor across from you. When you do, a wall will lower to
    your left, revealing Former Human Sergeants and a Former Commando. Kill all of
    them and
    then walk up to the eastern part of this room (where they came from). When you
    do, another wall will lower to your right, revealing Imps, Former Human
    Sergeants, and an
    opening. Kill all of them and then go through the opening.
    
    In here, kill all of the Former Commandos and then head up the stairs (if the
    stairs are not there, walk up on the staircase in the middle of the room). At
    the top, open the door, but do not go through it. Instead, head back down the
    stairs. Back at the bottom, get the Invincibility Sphere in the middle of the
    room. Now kill all of the Revenants and then go through the new opening in the
    western part of this room. In here, pick up the Red Key. Now head back up the
    same stairs you did earlier. At the top, go through the new opening. In here,
    turn left and you'll be facing the level's starting point, so go through the
    opening across from you. In here, kill all of the Imps. You'll also notice two
    cages with Arachnotrons in them. One of them has the Blue Key in them, but
    ignore this for now. Instead, open the Red Door in this room and go through it.
    In here, walk up to the door and both cages in the previous room will be open
    now. Kill both Arachnotrons and then pick up the Blue Key.
    
    Once you have the Blue Key, go back through the Red Door. In here, open the
    Blue Door in front of you and go through it. In here, open the door across from
    you and go through it. In here, kill the Mancubus in the middle of the room.
    Now open the door across from you and go through it. In here, open the door in
    front of you and go through it. In here, kill the Former Human Sergeants and
    then turn
    left. Follow this hallway until you see a door to your right, killing the other
    Former Human Sergeants and Former Commandos in this hallway. When you see the
    door,
    open it and go through it. In here, turn right and follow this hallway until
    you see a door to your left, killing the Former Human Sergeants in this
    hallway. When you
    see the door, open it and go through it. In here, pick up the Yellow Key and
    then leave this room. Back in here, open the door in front of you and go
    through it. In here, open the door in front of you and go through it. Back in
    this big room, get the Radiation Suit and then kill all of the Cacodemons.
    
    Now open the door across from you and go through it. In here, go through the
    opening to your left. Out here, the floor you're on will lower, but wait for it
    to rise again. Now follow this pathway until you see a switch to your right.
    Once you see the switch, hit it and the pathway to your left will lower, so
    fall down into the gap. Down here, open the door next to you and go through it.
    In here, you'll see a platform to your left and right. Kill the Arch-Vile on
    the right platform and then save your game. Now RUN onto the platform to the
    right (if you don't make it, reload your saved game). On here, get to the other
    edge of this platform. You see a smaller platform in front of you, so RUN onto
    it. On here, walk forward to be teleported and you'll be taken onto a mountain.
    Try to jump off of it, but then you'll exit the level.
    
    ---------------
    Level 28: Heck
    ---------------
    
    From the start of this level, kill all four Revenants that are on the pillar.
    When they are all dead, pick up the Super Shotgun, the Rocket Launcher, the
    Plasma Gun, and the Shotgun. Now take the southern pathway on here and go
    through the south opening. In here, pick up the Combat Armor in front of you.
    Now
    follow either hallway to an opening, and then go through it. In here, kill all
    of the Lost Souls and then kill the Arch-Vile on the pillar. There is also a
    Megasphere on the pillar. Hit the switch in this room to lower the pillar. This
    will also open a door, so get the Megasphere and go through the new opening. In
    here, go through the opening to your right. In this hallway, follow it to a
    pit, and then drop down to the pit. Down here, kill all of the Lost Souls and
    Demons. Now with your back facing the platform you jumped off of, lower the
    lift to your left, get on it, and ride it to the top.
    
    Up here, kill the Mancubi and then follow this walkway to the Red Key. Once you
    get to the Red Key, pick it up. Now get the Medikit and the Box of Shotgun
    Shells, and then head back down to the lower platform. Back down here, go
    through the opening across from you and head up the stairs in front of you. At
    the top, go through the opening to your left. In here, follow this hallway to
    another room. Back in this room, open the door to your left and go through it.
    You'll be right near the Arch-Vile. From here, you should backtrack back to the
    level's starting point. Get on the center pathway. Now take the western pathway
    and go through the west opening. In here, head up the stairs to your left. At
    the top, kill the Former Human Sergeant and the Former Commando, and then head
    down the
    next staircase. Now you'll be in a little maze. From here, go through the
    opening across from you. In here, go through the left opening. In here, take
    the right opening and you'll see a switch, so hit it, killing the
    Demons/Former Human Sergeants in this hallway.
    
    Once you hit this switch, backtrack back to the staircase you used to enter
    this room. Facing the staircase, go through the opening to the left. In here,
    head straight and you'll come across a 4-way intersection. Take the opening to
    the left. In here, follow the left hand wall until you get to the Blue Key,
    killing the Former Human Sergeants and Revenants in this maze. Once you have
    the Blue
    Key, get back to the staircase and go to the level's starting area. Get on the
    middle pathway and take the east pathway and go through the east opening. In
    here, kill the Imps and the Revenants. Now go through the large opening across
    from you. From here, follow this path to a gap. When you get to the gap, a
    platform with an Arch-Vile will rise (this is a lift as well). Kill the Arch-
    vile and drop down to the floor below you. Down here, kill all of the Pain
    Elementals and Revenants and then get the Yellow Key. When you have the Yellow
    Key, lower the next lift in this area, get on it, and ride it to the top.
    
    Back up here, backtrack to the level's starting area again. Back over here,
    take the north pathway and go through the north opening. In here, open the Red
    Door, then the Blue Door, and then the Yellow Door. In here, ignore the Lost
    Souls and fall in the pit, which will exit the level.

    Level 29: River Styx
    ---------------------
    
    When you start the level, go through the opening in this room, killing any
    Former Human Sergeants or Imps in your way. When you go through the opening,
    follow this
    tunnel to another room, killing any Demons, Lost Souls, Imps, or Former Human
    Sergeants
    in your way. When you get to another room, walk up to the platform in front of
    you (you can't get on it). Now, turn left, and follow this platform to a small
    set of stairs leading up to the platform.
    
    When you get to the stairs, use them to get to the platform. Up here, go
    through the opening across from you. In here, follow the right hand wall to an
    opening. When you get to the opening, go through it. In here, go through the
    opening in the north part of this room (don't worry, the lava won't hurt you).
    In here, follow this pathway to an opening, killing any Former Human Sergeants
    in your
    way. When you get to the opening, go through it. In here, go through the
    opening to your left.
    
    In here, go through the opening across from you. In here, go through the
    opening to your right. In here, go through the opening to your left. In here,

    you get to the teleporter, step on it. In here, head up the stairs and get the
    Blue Key in front of you.
    
    Now, turn back around and go back through the teleporter. Back in here, go
    straight until you see an opening to your right, and go through it. In here, go
    through the opening to the right (Watch out for crushing ceilings). In here, go
    through the opening to your left. In here, go through the opening in front of
    you. In here, hit the switch to your right. Now, go back through the opening.
    In here again, go through the opening to your left.
    
    Back in here, go way straight until you get to a gap. When you get to a gap,
    drop down it. Down here, go through the opening in front of you. In here, go
    through the opening to your right. In here, hit the switch in front of you.
    Facing the switch, turn around, and follow the left hand wall and you should
    come to a wall lowering, revealing an opening.
    
    Once the wall is finished lowering, go through the opening. In here, follow
    this hall to another room. In here, kill the Spider Mastermind, and get the Red
    Key. Now, turn back around, and leave this hall. Back in here, go through the
    opening across from you. In here, go through the opening to your right. In
    here, go through the opening to your left. In here, go all the way straight
    until you run into a wall.
    
    Now, turn right, and go through the opening in front of you. In here, follow
    this pathway to an opening. When you get to the opening, go through. In here,
    follow this hall to another opening, and go through. Back in here, use the
    stairs to get back on the pathways in this room. When you get back on the
    pathway in this room, use them to go through the opening in the south part of
    this room. In here, follow this pathway to the Red Door. When you get to the
    Red Door, open it, and go through.
    
    In here, open the Red Door in the south part of this room, killing any Mancubi
    or Arachnotrons in your way. When you open the Red Door in this room, go
    through, and take the teleporter. When you teleport, kill the Imps, Baron of
    Hell, and the Arch-Vile in front of you, and get the Yellow Key. Now, jump off
    the platform you're on. Back down here, open the Yellow Door in the east part
    of this room, and go through. In here, take the teleporter in front of you.
    
    When you teleport, kill the Pain Elemental in front of you. Now, go through the
    opening to your right. In here, open the door to your right, and go through. In
    here, kill the Former Human Sergeants in front of you, and hit the switch at
    the other
    end of the room. Now, turn right. You'll see the wall lower, revealing the exit
    teleporter. Step on it, and you'll exit the level.
    
    --------------------
    Level 30: Last Call
    --------------------
    
    Congratulations, you've made it to the final level of TNT!
    
    When you start the level, go all the way straight, picking up all the weapons
    in this room (yes, even the BFG for those who missed it in Dead Zone). Now,
    open the door in this room, and go through. In here is a room with platforms to
    get to the other end of the room. But you need to cross them in a certain way
    to get to the other end of this room, otherwise you'll be killed automatically.
    Use this map to help:
    
                 Finish
             [][]()[][][][]
             ()()()[][][][]
             ()[]()()()[][]
             ()()()[]()()
               []  []  ()
                       Start
    
                         X
    
    Say the X is you. The [] are the pillars that kill you if you step on them. The
    () are the pillars you need to step on to get to the other end of the pit. From
    the "Start", follow the () to the Finish and that's the correct path. Or here's
    a Walkthrough if you can't do it.
    
    There are 3 pillars in front of you. Get on the one to the right and follow
    these instructions (going on the pillars of course):
    
    -----------
    1. Up 1
    2. Left 1
    3. Up 1
    4. Left 2
    5. Down 1
    6. Left 2
    7. Up 2
    8. Right 2
    9. Up 1
    ------------
    
    From here, get on the floor in front of you.
    
    Now, when you get to the other end of the room, open the door over here, and go
    through. In here, follow this hall to an opening. When you get to an opening,
    go through. In here, go ALL THE WAY straight to the other end of the room. You
    should run into a wall that has a door on it. When you get to the door, turn
    around, and you'll see a switch. Hit it.
    
    When you do, walk up to the pit to the left. You should see a pathway in the
    pit rising to the switch. Cross the pathway to the switch, and hit it. Remember
    the door? It's now open, so go through. In here, follow this hall to a pedestal
    with a switch on it. Hit the switch, and the door next to you will open, so go
    through. In here, follow the left hand wall to a staircase. When you get to the
    staircase, kill the Cyberdemon on it. When it's dead, head up the stairs.
    
    At the top, hit the switch in front of you, and head back down the stairs. Down
    here, get to the pillar in the middle of the room. There are stairs rising to
    the top of it. Use them to get to the top, and at the top, get the Red Key.
    Now, drop down to the floor below you, and open the Red Door in the south part
    of this room, and go through. In here, hit the switch at the other end of the
    room, and turn around. You'll see stairs rise to the pillar in front of you.
    Use them to get to the top. At the top, take the teleporter.
    
    When you teleport, follow this hall to a door (get the power-ups as you go).
    When you get to the door, open it, and go through. In here, go all the way
    straight to the other end of the room. When you get to the other end of this
    room, there will be a teleporter to your left and right. Take either
    teleporter. Now, you'll be teleported to the final boss room. In here, head up
    the stairs in front of you. Now, hug the wall to the right/left until you get
    on top of the wall. When you do, follow this platform to until you see a lower
    platform to your left/right.
    
    When you see it, drop down it. On here, hit the switch on the pedestal, and the
    final boss on the wall will be activated. Also, the final boss shouts skulls
    boxes from its brain, and it will spawn into an enemy, except for Former Humans,
    Former Human Sergeants, Former Commandos, Lost Souls, Cyberdemons, or Spider
    Masterminds. Drop down to the floor below you, and head up either staircase. At
    the top of either one, head up the stairs to your left/right. At the top, kill
    the Barons of Hell, AND GET ON THE SECOND STEP TO THE TOP on the staircase.
    This is where you start firing at the boss.
    
    Now, facing the red hole (its brain) on the final boss (and standing on the
    second step to the top on the staircase), equip your Rocket Launcher and fire
    your Rockets into its brain. If it goes through, you'll hear a loud scream.
    Keep firing Rockets into his brain until you beat the level. Note that you will
    be firing at a small area under his brain. This is part of his brain but it is
    invisible. Once you beat the level, congratulations! Now, you get a little
    story:
    ------------------------------------------------------------
    Suddenly, all is silent, from one horizon to the other. The agonizing echo of
    Hell fades away, the nightmare sky turns to blue, the heaps of monster corpses
    start to evaporate along with the evil stench that filled the air. Jeeze, maybe
    you've done it, have you really won? Something rumbles in the distance. A blue
    light begins to glow inside the ruined skull of the demon-spitter.
    ------------------------------------------------------------
    Now, after the story comes the cast of enemies, showing their movements and
    growls. Press any key to scroll through each enemy.

    15.) TNT/Evilution Secrets
    ----------------------------------------
    Level 1: System Control
    ------------------------
    
    Number of Secrets: 1
    
    1. From the start of the level, open the door in front of you and go through
    it. In here, open the door to your left and go through it. In here, you will
    notice two pillars in the middle of the room. On the other side of both of them
    are switches. Facing the door, hit the switch on the right pillar. Now leave
    this room. Out here, go through the new door in front of you. This is a secret
    area. There is a Shotgun on the other side.
    
    -------------------
    Level 2: Human BBQ
    -------------------
    
    Number of Secrets: 4
    
    1. Once you have the Red Key, open the Red Door and hit the switch in the room.
    Now go back to where you get the Red Key and you'll see an open window. Jump
    through and get on the staircase. Now get to the Yellow Key. Once you have the
    Yellow Key, a door will open to your right. Get the Computer Area Map and
    you'll get a secret for free.
    
    2. Now, the Blue Key is not needed for the level, but you can use it for
    secrets. Once you have the Blue Key, jump back through the same window and up
    the stairs. Now, press Spacebar on all the walls until you find a hidden door.
    In front of you should be a switch. This is a secret room, but you can find
    some neat stuff if you explore.
    
    3. Near the end of the level, you will see a wall open. Hit the switch inside.
    Now go to the exit door and you will see a window to the left. Jump into it and
    in here, press Spacebar on the walls until you find a hidden door. It will
    reveal a Combat Armor, so pick it up when you find it.
    
    4. Near the end of the level, you will see a wall open. Hit the switch inside.
    Now backtrack to where the Yellow Door was. From here, go to where the Red Key
    was. As you approach where it was, you'll hear a door open. Go to your left and
    you will see a new opening, so go through it. In here, step through the
    teleporter. You'll be teleported onto a little post in the middle of the map.
    Next to you is a Soul Sphere.
    
    -----------------------
    Level 3: Power Control
    -----------------------
    
    Number of Secrets: 3
    
    1. From the start of the level, open the door. Now hit the switch on the middle
    building and step through the teleporter. In here, open the door. In this hall,
    open the door to the left. In this room, open the door with the blue symbols.
    There will be a teleporter. It takes you to a useless place, but step on it and
    step back if you want your secret credit.
    
    2. Once you have the Red Key, open the Red Door. Now in this hall, open the
    door in front of you. In here, check for a wall with blue symbols on it. This
    is a door, so open it. In this secret room is a Box of Shotgun Shells and a
    Rocket Launcher. Neat stuff you'll need.
    
    3. With your back facing the Blue Door in the middle room, head up the stairs
    to your left. At the top, step through the teleporter in front of you. In here,
    step through the teleporter you're on. Back on here, search the blue symbols
    walls near you for a hidden door. In here will be an Energy Cell Pack and a
    Medikit.
    
    ------------------
    Level 4: Wormhole
    ------------------
    
    Number of Secrets: 8
    
    1. This one is easy. At the start of the level, you will see a platform with
    Rockets and a Rocket Launcher on it. Lower this platform with the Spacebar and
    step on it. You'll get credit for an easy secret, but watch out, a wall in
    front of you will open, revealing tons of Former Commandos. Watch out. Wipe
    them out with your new toy.
    
    2. From secret 1, go through the new opening (where the wall opened). In here,
    open the door in front of you. In here, you will notice there are 2 candles in
    front of two parts of the wall. These are in front of hidden doors, so open the
    first one. In this room, walk forward to get credit for a secret.
    
    3. From secret 2, you'll be in a room with a lot of lifts. Use the lifts to get
    to a hall. At the top, follow the hall to a slightly bigger room, and you'll
    get to an area with three rectangular black walls. Once of them is slightly
    bigger than the rest. Press the Spacebar to lower this on and it will reveal a
    Box of Shotgun Shells and a Chaingun. Step on this to get a secret.
    
    4. From secret 3, there is an opening next to the rectangular walls. Go to it
    and then you will see a door across from you. Walk up to the door and you will
    get credit for a secret.
    
    5. From secret 4, open the door in front of you and go through it. Back in this
    hall, turn right and head all the way straight until a floor you're on lowers.
    Once you see the lowered floor, head down it. Down here, turn right and you
    will see blue and red pillars. Walk through them to be teleported. Once you are
    teleported, you will get credit for secret 5.
    
    6. Ok, now we teleported from secret 5. Looks like the same place, but it
    isn't. WE'RE IN A NEW WORLD. Just messing with you. Turn around and you'll see
    red and blue pillars. Walk through them and then head straight. Lower the lift
    in front of you, get on it, and ride it to the top. Up here, go through the
    opening to your right. In here, turn right. Now go all the way straight until
    you stop at a wall. This should be a hidden door, so open it and go through it.
    In here, you'll get credit for a secret.
    
    7. In secret 6, we're still not done with here. Walk forward and press Spacebar
    on the wall in front of you, and it will lower. Down in this "basement", kill
    all of the enemies. Now check for a Box of Shotgun Shells and search this room
    for a weird staircase. Once you find it, head up it. At the top, turn left and
    follow this passage to a staircase. Once you get to it, head down it. At the
    bottom, walk up to the door and you'll see a secret.
    
    8. Now we only need one more cheap secret. Looks like there are a lot of dead
    Imps on the ground already. Open the door in front of you from secret 7. Now
    turn right and you will see a dead Imp on the floor. Get in front of it and
    turn right. Now this wall is a hidden door, so step through it and you'll get a
    secret.
    
    For more secret goodies, lower the lift near secrets 7 and 8 (same place at the
    beginning of the level). If you look, you can get a Super Shotgun in this area
    and such.
    
    ----------------
    Level 5: Hanger
    ----------------
    
    Number of Secrets: 3
    
    1. After getting through the first 2 halls in the starting level, you'll come
    to a bigger room. Open the door to your left and go through it. Head down the
    stairs to your left in here. At the bottom, head down the stairs to your right,
    and then follow this hall to a door. Once you get to the door, open it and go
    through it. In here, look for a dark gray wall different from the others. Once
    you find it, open it and it will reveal a Backpack.
    
    2. From secret 1, leave this room and head back up the stairs. At the top, head
    up the staircase across from you (not the one to your left). As you are heading
    up the stairs, you will see an opening to your right. Go through it. In here,
    look for a gray wall different from the others. It's a hidden door, so open it
    and go through it. In here, follow this hall to a Chaingun.
    
    3. Now, remember how you saw an opening to the right heading to the staircase
    leading to secret 2? Put your back on that opening. In front of you is a wall.
    Press Spacebar on it and it will open, revealing a Box of Shotgun Shells and an
    Armor.
    
    ---------------------
    Level 6: Open Season
    ---------------------
    
    Number of Secrets: 1
    
    1. From the start of the level, progress the whole level all the way until you
    get to the Red Key. Once you have the Red Key, turn right. You'll see different
    designed wall. This is a door, so open it and it will reveal a Soul Sphere. This
    is your only secret. Man, they need better disguising for the secret areas.
    
    ----------------
    Level 7: Prison
    ----------------
    
    Number of Secrets: 4
    
    1. From the start of the level, head straight and open the door at the end of
    the hallway. Now head up BOTH staircases in this room. This will create a
    pillar to the teleporter and lower the walls surrounding it. Facing the
    teleporter, drop down to the floor to the right. Down here, look for a slightly
    different colored wall. This is a hidden door, so open it and it will reveal a
    switch. Hit this switch and it will lower another wall. Go back up the stairs
    to face the teleporter. This time, drop down to the floor to the left and look
    for a new opening. In it is a Berserk. That is your secret.
    
    2. Now, progress all the way through the game until you get to the fortress
    like structure. At the top is a switch you need to hit to get through the level
    and a Soul Sphere on a pillar. To get the Soul Sphere, go out the opening to get
    to the outer part of the fortress. Now head left and you will hear the sound of
    a lift dropping. Go back inside where the switch and pillar is and now the
    pillar has lowered. Step on it to get credit for a secret.
    
    3. Once you get past the fortress, there will be a bridge to get to the middle
    part of the map. Now get to the lift where you need to hit the switch and lower
    the teleporter on that square structure. Hit the switch now. Instead of going
    through the teleporter, go on the other side of the structure of where you are.
    Another lift has lowered, so get on it and ride it to the top. There is a
    secret and an Invincibility Sphere up here. If you don't get to it, try again.
    
    4. A LOT of people have problems with this secret. Once you have the Red Key,
    open the Red Door and go through it. In here, go all the way straight to the
    other end of this room. Once you stop at a wall, turn left and you will see
    three pillars in the pit. Now, if you notice at the BOTTOM of the pillars, one
    of them has yellow lights around them. Drop down to the pit to this pillar.
    Now, look for a black spot on the pillar. Press the Spacebar on this part of
    the pillar, and a wall above you should lower. To get to it, go back through
    the teleporter. Now, with your back on the Red Door, there should be a new
    opening across from you. In it is a Soul Sphere, so grab it before you leave the
    level.
    
    ---------------
    Level 8: Metal
    ---------------
    
    Number of Secrets: 4
    
    1. At the start of the level, turn around and you will see a door. To get this
    door open, face the door and look at the wall to the right. With the door right
    to your left, press the Spacebar on this wall and the door will open, revealing
    a secret area. In this secret area is a nice little Chainsaw.
    
    2. Once you get out of the maze like area at the start of the level, you will
    get to a room with a staircase in it. Head up the staircase and open the door
    at the top and go through it. In here, you will be in a big room with a cage to
    your left and your right. Get in front of the cage to your left. Now shoot it
    with a Pistol, either Shotgun, or a Chaingun. Now turn around and face the
    other side of the room. There will be two new openings, so go through the one
    on the right. There is a switch in this room and you will get credit for a
    secret for stepping in here. This switch lowers a platform with a Super Shotgun
    and Armor on it.
    
    3. From secret 2, open the door in this room and go through it. In here, go
    through the opening to the left and you should see a barrel in front of a wall.
    Go all the way straight to the wall and get in front of it. Press Spacebar on
    the wall and it will lower. Down here, there is a Soul Sphere. Step forward and
    you will get credit for a secret.
    
    4. This secret is needed for getting through the level. Now, on your way to the
    Red Key, you will need to open a secret looking door. It is a different design
    from the walls around it, so once you find it, open it and go through it. Now
    you have an easy secret.
    
    --------------------
    Level 9: Stronghold
    --------------------
    
    Number of Secrets: 11
    
    Oh boy, 11 secrets. Hmm, where should I start.
    
    1. From the start of the level, open the door to your right. In here, hit the
    switch to open the door and go through it. In here, open the door at the other
    end of this room. In this room, you'll see a wall in between two pillars in
    front of you. At the bottom of the wall should be a yellow light. This is a
    door, so open it and go through it. In here, head up the stairs to your left
    and stop at the wall to get credit for a secret.
    
    2. Now, progress the game until you have the Red Key. Once you have the Red
    Key, leave the crate room. In here, open the door to your right and go through
    it. In here, head up the stairs to the left. At the top, hit the switch that
    needs the Red Key, and then turn around. You will see a blue striped wall next
    to the staircase. This is a left, so lower it, get on it, and ride it to the
    top. Up here, get the Medikit and the Armor, and you'll get a secret as well.
    
    3. From here, continue to progress until you get to the Blue Key. Before you
    get to the Blue Key, there is a staircase leading to it. Also at the bottom is
    a Backpack on a pedestal. Put your back on the pedestal and look straight. You
    will see openings to your left and right. Go through the third opening on the
    left. In here, there should be a triangle symbol on the wall. Open this as a
    door and go through it. In here is ammo, and you'll get credit for a secret.
    
    4. From secret 3, there is another wall to your left with the triangle symbol
    on it. This is a lift, so lower it, get on it, and ride it to the top. Up here,
    get to the end of the hallway and you'll stop at a wall. Once you get to it,
    the floor you're on will lower and you should land on the pedestal with the
    Backpack on it. This will give you a secret as well.
    
    5 and 6. Now, get the Blue Key and progress until you get to the room with the
    big slime pit in the middle (by hitting the switch that needs the Blue Key,
    going through the new opening, and heading through the door to the right). At
    the other end of the room is a lift you need to go down, but stop right in
    front of the lift. Turn right and you will see a wall with a yellow light on
    it. Press the Spacebar to lower this wall and it will reveal a secret area.
    Step through and you will get credit for 2 secrets.
    
    7. Now, from secrets 5 and 6, go back to the lift and drop down it. Down here,
    look for a slightly different designed wall to your right. This is a lift, so
    lower it and get on it, and ride it to the top. Up here, walk forward and you
    will get credit for a secret.
    
    8. One little weird secret. In the room of secret 7, walk in the middle of the
    room near the computer areas and you will see a Box of Rockets. Collect it for
    your secret.
    
    9. We're still not done with this secret room. In this room are two
    teleporters. Step on the one to the left first, and you'll be taken to a secret
    area with a Rocket Launcher in it. Pick up the Rocket Launcher and then step
    back through the teleporter.
    
    10. Back in the room with the teleporters, enter the teleporter to the right
    this time. Now, you know the room you used to get to secret 7? You are on the
    higher ledges in this room. Walk up forward and get the Box of Rockets. Now
    you'll get credit for a secret.
    
    11. In the room with the exit door, there is a staircase with health and Armor
    Bonuses on it. Get to the bottom of the staircase and turn right. There is a
    wall with blue symbols on it. This is a door, so open it and go through it. In
    here, head up the stairs to your left. At the top, walk forward and you're
    finally done with all secrets. Up here is just a lousy Stimpack.
    
    ---------------------
    Level 10: Redemption
    ---------------------
    
    Number of Secrets: 5
    
    Ok, the way of getting these secrets are really weird, but you get all 5 of
    them at once. First, start the level by opening the door across from you and
    then going through it. In here, hit the switch to open the door in front of
    you. Now lower the lift. There is a door to your right. Facing the door, turn
    around and press the Spacebar on the wall (the lift needs to be at its lowest).
    It will open, revealing a staircase. Head up it and you will get 4 secrets.
    Open the door and walk straight to get your final secret.

    Level 11: Storage Facility
    ---------------------------
    
    Number of Secrets: 2
    
    1. From the start of the level, go through the opening to your right. Out here,
    get to the storage areas. Before entering this area, you'll see a Blue Door and
    two doors to the left of it. Open the door to the left of the middle door and
    go through it. In here, follow this little passage until you see an opening to
    your right. Once you see the opening, go through it. In this small hallway,
    press Spacebar on the walls to the right and it should open, so go through it.
    Walk forward to get a secret.
    
    2. From secret 1, there is a lift in front of you. Lower it and get on it. Now
    you will get credit for a secret.
    
    At the top of the lift is a wall. Inside of it is a Megasphere. To get it, get
    back to the bottom of the lift. Before lowering it, leave this secret room.
    Back out here, turn left and you will see a room full of crates. Use them to
    get to the opening above the lift. Memorize this path. Now go back to the
    secret lift and walk up to it. You should hear the sound of a door opening, so
    leave the room, through the opening to your left, and RUN up the crates to the
    opening. The door should be up, so get the Megasphere while you can.

    1. Once you have the Red and Blue Key, get to the Red Door. Now hit the switch
    to lower the lift. Down here, get to the lift where the Arch-Vile is. You need
    to lower it and walk through it to get to the exit. But instead of doing that,
    get on the lift and ride it to its highest point. Up here, get the Berserk to
    your left for a secret.
    
    2. Secret 2 is just across from secret 1. To the right of this lift is an
    Armor, and two sets of Shotgun Shells. Open the door next to you for a neat
    little passage.

    2. From secret 1, go through the opening to your right. In here, open the
    hidden door in front of you and it will reveal a Backpack. Collect it to get
    your 2nd secret.
    
    3. Now, leave this room and go back to the level's starting point. You will see
    a crate. Press the Spacebar to lower it and then it will show a shortcut to the
    outside area. Step on the crate to get credit for a secret.
    
    4. Instead of taking the shortcut, go through the opening to your left. In
    here, head up the stairs across from you. At the top, turn right and you will
    see a wall with a lot of designs on it. Get to the left half of the wall and
    you will see a different designed wall in between two ones that are the same.
    This is a hidden door, so open it. In here, get the Armor, and you'll also be
    in a secret room.
    
    5. All of these secrets are coming early, damn. Well, from secret 4, leave the
    secret area and go through the opening to your left. In here, lower the lift
    across from you, get on it, and ride it to the top. Up here, follow this path
    until you stop at a wall. To the right is a set of designed walls. Press the
    Spacebar on them until the hidden door opens, revealing a Medikit and a Box of
    Shotgun Shells. Step through for a secret.
    
    6. Ok, this secret won't come for a long while. After you get to the Red Key,
    hit the switch to open a door. Now step through the teleporter and you will get
    to a hallway. Notice the right hand wall. When you see yellow and red designs
    on one part, you'll know you've found a hidden door, so open it and go through
    it. In this secret area, get the Combat Armor.

    until you get to the room with the all of the crushing ceilings and the lifts.
    Once you get to that room, put your back on the opening you came out of to
    enter the room. Now turn left and you will see two lifts. Lower the one on the

    you with a Pistol, either Shotgun, or a Chaingun, and a wall to your left will
    lower, revealing a switch.
    
    Hit the switch and then go to the lift to the right of this one. Now lower it,

    then a wall to your right will open, revealing a Rocket Launcher. Pick it up
    for a secret.

    to it. Down here, get the Soul Sphere for a secret.
    
    3. From secret 2, there will be a teleporter to your left and right. Enter the
    one on the left to progress the game and get the Red Key. Now once you have the
    Red Key, go back to the pit with the two teleporters. Enter the one to the
    right this time. From here, backtrack to the room with the crushing ceilings
    and lifts. This time, Facing the lift that needs the Blue Key, turn right and
    face this lift. Now lower it, get on it, and ride it to the top.
    
    Up here, RUN to the other end of the room. In here, get the Light Amplification
    Visor for a secret.

    hear it, go to the previous room and get on the lowered lift, and then ride it
    to the top. Up here, get onto the platform to your right. Now walk straight and
    the floor you're on will lower, revealing a secret area and a Chainsaw.

    Now you have a secret.
    
    6. Since we're back outside from secret number 5, we'll have to go back in.

    hand wall until you get to a staircase. Once you get to it, head up it. At the
    top, you'll see a poison symbol on the wall. This is a hidden door, so open it
    and it will reveal a Backpack. Pick it up for a secret.

    it. Out here, turn around and you'll see a wall that is brighter than all of
    the other walls around you. This is a hidden door, so open it and it will
    reveal a Box of Bullets. Go through it and collect it if you want a secret.

    it. In here, go all the way right until you see a door to your right. Once you

    them is slightly designed different than the others. This is a hidden door, so
    open it. In here, the wall in front of you is a door. Open it and go through
    it. Back out here, you will be on a secret platform. Across from you is a Super
    Shotgun.

    it. In here, go through the opening to your right. In this hallway, you'll
    notice a wall without white lights on it. This is a hidden door, so open it and
    go through it. In here, step forward and you'll get credit for a secret.
    
    2. Staying in secret 1, open the door in front of you and go through it. Out
    here, turn right and go straight on this walkway. To your right is a wall. If
    you notice, one of them has a yellow light on it. This is a hidden door, so
    open it and go through it. In this secret area, step down to the floor below
    you. Down here is a nice Invincibility Sphere.
    
    3. Progress the game until you have the Blue and the Red Key. Stay in the room
    where you get the Red Key. There is a door in this room. To the right of it is
    an opening. Inside the opening is a switch. Hit it and then go back to the door
    and then go through it. In here, go through the opening at the other side of
    this room. In here, go through the opening to the left. In this big room, go
    all the way straight to the other end of the room. Over here, you'll notice a
    pillar hanging from the ceiling that is next to a Box of Rockets. On the pillar
    is a switch.
    
    Hit it. Even though it is in the air, get in front of it and press Spacebar.
    Now facing the switch, go through the opening to your left. In here, hit the
    switch across from you. Now facing the switch, drop down to the floor to your
    left. Down here, look for a fake wall (hold up against all of the walls). Once
    you find it, you will find a hidden Megasphere inside. Grab it. Now leave this
    area to be teleported.
    
    4. Now, get to the Red Door, and then open it and go through it. In here, get
    to the switch at the other end of the room. Now hit the switch and all of the
    lifts in this room will lower. Get on the lift on the wall to the right, and
    then ride it to the top. Up here, go through the opening at the other end of
    the room. In here, head right to the lift. Now lower it, get on it, and ride it
    to the top. Up here, you'll see an opening to the right. Now, facing the
    opening, search the walls on the left for a hidden door. Once you find it, go
    through it. In here, follow this hallway to a Soul Sphere (across from the
    secret Invincibility Sphere).
    
    5. Once you have all of this, progress the game to the end of the level. Before
    you step on the exit teleporter, look across from it. You'll see an
    Invisibility Sphere on a higher ledge across from you. To get to this, leave
    the room and turn left. Now you will see a Soul Sphere and a light post. The
    hidden door is to the left of the light post. Once you find it, go through it.

    1. From the level's starting point, open the door in front of you. In here,
    open the door in front of you and go through it. In this hallway, turn left and
    follow it to a door. Once you stop at a door, turn to the right. You'll see a
    flashing light onto a wall. This is a lift, so lower it, get on it, and ride it
    to the top. Up here in this secret area, there is a Soul Sphere.
    
    2. From secret 1, open the door at the end of the hall and go through it. In
    here, go all the way straight to the other end of the room and you will get to
    a door. Once you get to the door, open it and go through it. In here, head up
    the stairs to your left. At the top, you'll see a door leading to the next
    room. Face it and then turn around. See that wall across from you? If you
    notice, one of them has a different design than the others. This is a fake
    wall. Walk through it and you'll get to a secret with a Backpack in it.
    
    3. From secret 2, turn around. Now open the door across from you and go through
    it. In here, turn left and you will see a switch. Facing the switch, turn left
    and you will see a wall with some picture on it (wonder what the hell it is).
    This is a lift, so lower it, get on it, and ride it to the top. Up here, you'll
    be outside of this little "factory". Also out here is a nice little Megasphere.
    For some weird reason, I keep forgetting how to get here.
    
    4. Now progress the game until you get to the Blue Key. Once you get to the
    Blue Key, go through any of the Blue Doors. In here, use the switch to open the
    doors leading to the Red Key that is inside the truck. Also in this room is a
    platform with a Rocket Launcher on it. To lower this platform, you'll see a
    step where barrels are. Step on that step to lower the platform. Now get on it
    and get yourself credit for a secret.

    Level 20: Central Processing
    -----------------------------
    
    Number of Secrets: 7
    
    1. From the start of the level, open the door to your right and go through it.
    In this big room, search for the teleporter in this room. Once you find the
    teleporter, step through it. In this room, you'll see smaller crates leading up
    to a big one. At the top, get the Box of Shotgun Shells and then turn left.
    That crate is a door, so open it and go through it. Now drop down to the floor
    below you to get credit for a secret.
    
    2. Down in this crate area, look for a light post. To the right of the light
    post is the hidden way out, so open it and go through it. Back out here, a new
    part of this room will be revealed. In the corner is a pillar. Lower it and get
    on it to get credit for a secret. But if you ride it to the top, you'll see a
    BFG. Get it. To get out of this room, shoot the switch across from you with a
    Pistol, either Shotgun or a Chaingun. Now use the stairs leading to the BFG to
    RUN over the ledge. Now step through the teleporter.
    
    3 and 4. These secrets won't come for a while. Now progress the game until you
    get to the Blue Key. Now, if you are playing on skill levels 1 and 2, you will
    already get credit for these two secrets. On skill levels 3, 4, and 5, you'll
    need to cross this hallway, as the Blue Key is in different locations depending
    on your skill level. Now, going through the long hallway with the Invincibility
    Sphere in it has two secrets. They will be added to your credit as you go, and
    you should have 2 at the end of the hallway.
    
    5. Now progress the game to the Yellow Key. Once you get to it, pick it up. Now
    turn around and face the door you need to open. To your right is a wall. Press
    Spacebar on it until you find a hidden door. Once you find the hidden door, it
    will open, revealing an Invincibility Sphere. This is one secret in this room.
    
    6. Secret 6 is just around the corner from secret 5. To find this hidden door,
    it is to the left of the hidden wall leading to secret 5. Once you find the
    hidden door, it will show another secret area, revealing an Energy Cell Pack.
    
    7. At the end of the level, you'll have to go on that really, really, long
    walkway. But let's be a little more clear. Go through the Yellow Door, and then
    drop down to the river. Down here, head right into the opening to be
    teleported. Now drop down to the floor below you. Down here, open the door to
    your left and go through it. In here, step through the teleporter to the right.
    Now on here, get the Soul Sphere and find a hole in the cages. Now drop down to
    the pit and look for a teleporter. Once you teleport, head up the stairs in
    front of you. At the top, lower the lift in front of you.
    
    Instead of getting onto the walkway, ride it to the top. Up here, get the
    Energy Cell Pack and lower the wall in front of you. It will reveal a secret
    area and a teleporter. Step through the teleporter to take a shortcut going
    down that long walkway.
    
    --------------------------------
    Level 21: Administration Center
    --------------------------------
    
    Number of Secrets: 4
    
    There are 4 secrets, but half of them are complex and take a lot of skill to
    find out and such.
    
    1. From the start of the level, progress the game to the Red Key. Once you have
    the Red Key, step through the teleporter next to you. In this room, get to the
    other end of the room. Now turn around and you will see a black flag on the
    wall to the right. This is a door, so open it and go through it. In here, walk
    forward and you will be teleported. Now open the door in front of you and go
    through it. In here, open the door next to you and go through it. In this hall,
    open the door to the right and it will reveal a thin ledge and a pit. Walk to
    the end WITHOUT falling in the pit.
    
    If you went out far enough, a wall behind you will lower, revealing an opening,
    so go through it. In here, open the door to your right. Now open the door in
    front of you and go through it. In here, turn right and you will see a health
    potion against the wall. The wall it is in front of is a hidden door, so open
    it. In this secret area is a pair of Medikits. Collect them at your will.
    
    2. From here, drop down to the floor to your right. Now progress the game until
    you have the Yellow Key. Once you have the Yellow Key, step through the
    teleporter where the Red Key was. Back in here, open the door to your right and
    go through it. In this hall, turn right. Now you should see a wall lowering to
    your right. Go through the first opening. In here, there should be a picture on
    the wall in front of you. This is a door, so open it and go through it. In
    here, step onto the blue teleporter. Now in this room, turn left and you will
    see a door, so open it and go through it. Save your game because you won't want
    to mess up here.
    
    In here, you'll see a little "pyramid" with a Rocket at the top. Around it is a
    red walkway. To get to the walkway, RUN to the top of the pyramid and then RUN
    over the gap onto the walkway. Now follow this pathway until you stop at a
    wall. Once you stop at it, walk through it and you'll be in a secret area with
    a BFG. If not, go to the opposite wall.
    
    3. Now to get out of secret 2, head back up the stairs in the room. At the top,
    open the door to your left. Now open the door in front of you. In here, step
    through the teleporter to your left. Now progress the game until you have the
    Blue Key. Once you have the Blue Key, open the Blue Door and go through it. Now
    get through this room by using the teleporter to get outside (use the
    walkthrough if you need to or if you already know). Once you teleport, drop
    down to the pit behind you. Down here, hit the switch and the floor you're on
    will raise. Now turn around and face the door. To the right on the wall is a
    hidden door, so open it and it will reveal a Combat Armor. This is your secret.
    
    4. Now from secret 3, open the door to your right and go through it. Out here,
    turn left and notice the wall on the right. At the end there are two blue
    torches. Press Spacebar on the wall between the two blue torches and it will
    lower, revealing an Invincibility Sphere. Pick it up and go back, and then
    you'll be teleported. On here, drop down to the floor below you and you'll get
    credit for a secret. To get out of here, get to the Soul Sphere and you'll be
    teleported.

    Level 22: Habitat
    ------------------
    
    Number of Secrets: 9
    
    First, before we start out secret frenzy, we'll need the Blue Key first, but it
    isn't needed for beating the level. To get the Blue Key, go through the opening
    to your left. Out here, head up the stairs to your right and continue straight.
    A door will open, revealing a wall. This is a fake wall, so walk through it and
    you will get the Blue Key. Now let's backtrack to the level's starting point.
    
    1. At the level's starting point, turn around and face the wall. You will see
    part of the wall is sort of "bent" and not even with the other walls. This is a
    fake wall, so go through it. You'll get a secret.
    
    2. Staying behind this fake wall, get the Soul Sphere in front of you for credit
    with your secret.
    
    3. Once you get the Soul Sphere, a big crate outside will lower, so RUN to it.
    If not, go to where the Soul Sphere was and try again. Once you get past it, hit
    the switch behind the crate. The floor to your right will lower, so head down
    it. Down here, head up the created stairs in front of you. At the top, get the
    BFG.
    
    4. From secret 3, hit the switch to lower the lift in this room. Now get back
    on it and ride it to the top. Up here, lower the crate in front of you, and
    walk through it. Now you will see two slime pillars. You can walk through them.
    Once you do, walk forward and the lift you're on will lower. Down here, walk up
    to the Super Shotgun and turn left. You will see a wall surrounded by two brown
    strips. This is a door, so open it and go through it. Now you'll hear the sound
    of a door opening. Go back to the previous room and you'll see a Chainsaw to
    the left. Pick it up and the doors around you will open. Step through them for
    a secret.
    
    5. Now the bad half of these secrets. Go back to the opening to the right, and
    you'll be in a huge maze. Time to navigate ourselves around here. From the
    start of the maze, head right to an opening. Once you see an opening, you'll
    see one to your left and right. Go through the one to the left. Down this hall,
    go all the way straight to the end of the hall. As you go, a wall to your right
    will open, revealing an opening. Once you see it, go through it.
    
    In here, walk forward to the wall. Now turn around and leave this room (if the
    lift rises, hit the switch next to you). Back in this maze, turn left and go
    all the way straight until you see an opening to your left. Once you see it, go
    through it. In this hallway, go all the way straight to the other end of this
    hall. Near the end, a wall to your right will open, so go through it. In here,
    open the Blue Door in front of you and go through it. In here, get the Yellow
    Key. Once you have the Yellow Key, turn around and leave this room the same way
    you entered it.
    
    Back in here, turn left. Now head straight until you see an opening to your
    right. Once you see the opening, go through it. In here, run straight until you
    see a wall open to your right. Once you see it open, go through it. In this
    hallway, follow it until you see an opening to the left. Once you see it, there
    should be a Medikit in it. Step in it to get credit for a secret.
    
    6. In the small room with the Medikit in secret 5, turn back around and go
    through the opening in front of you. Back in this hallway, turn right and you
    will get to a door when following this hallway. Open the door and hit the
    switch to get out of here. Back in this maze, head right to the wall and it
    will open, so go through it. In this hall, follow it until you see an opening
    to your left. Inside the opening are health potions. Step through it for a
    secret.
    
    7. Secret 7 is just around the corner. In secret 6, there is a fake wall to the
    left. Go through it. In here, there is a pillar with the Red Key on it. To
    lower the pillar, leave secret 6 through either opening and RUN back to the
    pillar. It should be lowered, so get the Red Key.
    
    8. Facing the pillar with the Red Key on it, turn around. Leave this room. Back
    in secret 6, go through the opening to your left. In this hall, turn right and
    follow this hallway until you see another opening to your right. Once you see
    it, it should be a small room, so step into it for credit for a secret.
    
    9. From secret 8, go into the all in front of you. In here, turn left and
    follow this hallway to a Yellow Door. Once you get to the Yellow Door, open it.
    In here, follow the stairs to another Yellow Door. Once you get to it, go
    through it. Now lower the lift in front of you and drop down to the pit below
    you. Down here, walk up to the middle of the silver wall in front of you and it
    will lower. Now progress the game until you get to the exit room. Before
    stepping in the pit, open the Red Door behind the pit. You'll be teleported. In
    here, get the Combat Armor and step back through the teleporter. You'll get your
    secret.

    hall leading to the teleporter, which takes you to the Blue Key. As you head
    down the hall, you'll hear the sound of a lift dropping. Once you here it drop,
    walk through the fake wall to your right and you should find a small secret
    room with a Radiation Suit in it. You'll know where it is because you'll see
    the wall in between two brown bars.

    the Blue Door. Facing the Blue Door, drop down to the floor to your right. Down
    here, go through the opening next to you. In this hall, you'll notice one wall
    is darker than the others. This is a hidden door, so shoot it with your Fist,
    Chainsaw, Pistol, either Shotgun, or the Chaingun, and it will open. In this
    secret room is an Armor, Box of Shotgun Shells, Stimpack, and a Super Shotgun.
    
    3. Facing the Armor in secret 2, turn left and face the wall. The wall in front
    of you is a lift, so lower it, get on it, and ride it to the top. Up here,
    there will be a Box of Shotgun Shells in front of you.

    ground below you. Down here, turn right and you will see a door at the bottom
    of the stairs. Open it and go through it. In here, turn left and lower the
    pillar in front of you to reveal a teleporter. Step through it to be taken to
    the other side of this room. Over here, open the door across from you and go
    through it. In here, you'll see a pedestal with a switch on it. Turn left
    facing the pedestal and you will see a lift (in between two brown bars). Hit
    the switch and RUN to the lift. Lower it to reveal a door. Open it and go

    In here, head straight to the staircase across from you. Head down it. At the
    bottom, a door to your right will open, revealing a Yellow Key. Pick it up.

    down to the slime river below you. Down here, follow this hallway to another
    opening. Once you get to it, go through it. Out here, you'll notice a pillar in
    the middle of the room. Open the door to your left. In here, hit the switch and

    building. Use the small stairs to get to the building. Now if you notice the
    torches, one of them is green. Before getting to it, get to the right of the
    opening. Now remember where to go. Now go back to the green switch and press

    that room, you'll automatically get credit for a secret.
    
    ------------------
    Level 31: Pharaoh
    ------------------
    
    Number of Secrets: 2
    
    NOTE: Since this level has a bug that stops you from using the Yellow Key, you
    will need the Yellow Key for getting both of the secrets. Use the patch from
    www.teamtnt.com to get the Yellow Key, and then you're good to go.
    
    1. Once you have the Yellow Key, get to the Yellow Door. Now open it and hit
    the switch inside. From here, go back to the level's starting point. Back in
    here, look for a new teleporter and then step through it. In here, head up the
    stairs to your left. At the top, hit the switch. Now head back to the floor
    below you. Down here, go through the opening across from you. In here, hit the
    switch. Now turn around and you'll see two switches. Hit the one on the left
    and turn around. You'll see two new pedestals. Hit the Spacebar on both of them
    to activate them like switches. From here, head up the staircase in front of
    you. At the top, turn right and get to the opening across from you. You will
    have credit for a secret by the time you reach the opening.
    
    2. Once you get to the opening, drop down to the floor below you. Down here,
    follow this hall to a switch and then hit it. Now go back and hit this switch,
    and the floor you're on will rise. Back up here, head down the stairs again.
    Down here, go through the new opening to your left. In this hallway, follow it
    until you see a red torch on the wall. Once you see it, stop at it and turn
    right. The wall in front of you is fake, so walk through it. In here, get the
    Combat Armor and you will get credit for a secret.

    bridge, cross it. Over here, open the door in front of you and go through it.
    In here, go through the opening to your right. In here, follow this hallway to
    a staircase and then head up it. At the top, follow this hall to an opening.

    it. In this secret area are two Medikits and ammo.
    
    2. Now progress this game until you have the Yellow and the Blue Key. Once you
    have both, stay in the room with the Yellow Key. Now lower the lift in this

    back to the door we used to enter the building. Once you get back to it, open
    it and go through it. In here, go through the opening to your right. Back in
    here, you'll see a new Combat Armor across from you. Walk up to it and turn

    it to the top. Back out here, you'll notice the door leading to the BFG has
    opened, so go through it. In this secret area, get the BFG and the goodies
    here.

    16.) TNT/Evilution Bugs and Errors
    ----------------------------------------
    This section shows all known bugs and errors I've found. Email me if I miss
    any!
    
    1. In Level 3: Power Control (TNT) you will notice that there are a few small
    rooms inaccessible on the map if you were to turn the full Automap cheat on.
    These small rooms are located mostly near the Blue, Yellow, and Red Doors. One
    even has a Plasma Gun in it. There is no way to get into these rooms unless you
    are playing online, where the teleporter at the beginning of the game will
    randomly teleport you to one of those areas. This is what I got playing in Doom
    Legacy, I haven't tried it in other source ports.
    
    2. Level 28: Heck (TNT), just before you go in the pit with the Yellow Key, a
    platform in front of you which is a lift rises, revealing an Arch-Vile. If you
    run straight to the pit before the platform rises to you, the platform may not
    rise, and in the pit (where the Yellow Key is), you won't be able to get out of
    it because the platform didn't rise, so you can't lower it.
    
    3. In Level 30: Last Call (TNT), there is another major error. In some versions
    of TNT, whenever you hit the switch in the Red Key room, the stairs to the Red
    Key may not rise completely, so the only way to get to the Red Key is to cheat.
    www.teamtnt.com has a patch to fix this error as well.
    
    4. In Level 31: Pharaoh (TNT), the Yellow Key is missing from the level,
    preventing further progress into the level. There is a way to exit the level
    without using any Key. My Walkthrough shows how to exit the level without any
    keys, because the odds are your Final Doom (TNT) won't have the Yellow Key in
    Pharaoh.
    
    If you want to try the level with all 3 Keys, go to www.teamtnt.com and go to
    Bugs and Fixes. Download the patch to fix this error (tnt31.wad), then, when
    before you play Pharaoh, use TNT.wad as the PWAD and tnt31.wad as one of the
    Iwads, then the error is fixed (as long as you're using the Iwad). If you want
    a Walkthrough using all 3 Keys ask me.
    
    --------------------------------------------------------------------------------
    
    17. Alternate Pharaoh Walkthrough
    ----------------------------------------
    
    Remember how I told you that you could not get the Yellow Key in Pharaoh
    because of a bug? Well, the walkthrough I have has a walkthrough for getting to
    the exit using the patch to fix the bug. If you are not able to get the bug
    fix, use this Walkthrough below. It shows the alternate way of getting the exit
    by using the shortcut.
    
    When you start the level, hit the switch in front of you, and the walls will
    lower, revealing loads of ammo, weapons, and health. Now go straight, and get
    to the other end of the room, killing any Former Human Sergeants in your way.
    Over here
    there is an opening. Go through. In here, kill the Former Commando and hit
    the switch in here. Now leave this room. Back out here, go straight until you
    see an opening in the pyramid to your left. When you see the opening, go
    through. In here, get to the opening at the other end of the room, but don't go
    in the gap. Instead, look at this map:
    
                               _____________
                              |             |
                              |   Chair     |
                              |             |
                              |_____________|
    
    
    
    -----------   Opening     -----------------
    
             X
    
    Say the X is you. Get to the left of the opening, and hold Alt and Shift. Now
    "Strafe Run" through the opening to get to the chair (use "Right" on the Arrow
    Key). This will take a lot of attempts to get on the chair, because it is hard.
    If you don't make it, hit the switch down here, and it will create stairs, and
    try again. When you finally make it, get your back on the edge of the chair
    (don't fall off). Now press the Spacebar and you'll hear the sound of a switch
    being hit. So turn left and you should see a new opening. Hop off the chair,
    and go through.
    
    In here, go all the way straight and get to the opening at the other end of the
    room, and go through. In here, head up the stairs, and the wall in front of you
    will open, revealing a Megasphere and a switch. Get the Megasphere, and hit the
    switch. Now, turn around, and go back through the opening. In here, follow the
    left hand wall to an opening, and go through. In here, go all the way right to
    the other end of this room, and hit the switch. Now turn around, and go through
    the opening to your left.
    
    Back in here, go through the opening across from you, killing any Former Human
    Sergeants
    in your way. In here, wait for the wall in front of you to lower. When it's
    done lowering, go up the stairs in front of you. At the top, go through the
    opening across from you. On this pathway, drop down in the water to your right.
    Down here, go through the opening across from you, and you should come to a
    wall surrounded by an arch. Press the Spacebar to lower the wall, and when it's
    done, go through.
    
    In here, get all the health and armor bonuses, and with your back against the
    opening, press the Spacebar on the wall at the other end of the room, and it
    will lower, revealing the exit switch. Hit it (this takes you to the secret
    exit ;)).
    
    Now, before you enter the next level, you get a little story:
    -----------------------------------------------------------
    Time for a vacation. You've burst the bowels of Hell and by golly you're ready
    for a break. You mutter to yourself, maybe someone else can kick Hell's ass
    next time around. Ahead lies a quiet town, with peaceful flowing water, quaint
    buildings, and presumably no Hellspawn. As you step off the transport, you hear
    the stomp of a Cyberdemon's Iron Shoe.
    -----------------------------------------------------------
    
    --------------------------------------------------------------------------------
    
    18.) The Plutonia Experiment Walkthrough
    ----------------------------------------
    Level 1: Congo
    ---------------
    
    You start the level standing on a Box of Shotgun Shells. You'll see three
    openings in front of you. Take the one on the left, and open the door. In here,
    follow the staircase to another room. At the top, kill the Former Human
    Sergeants and
    grab their Shotguns. Now go through the opening. Follow the hall to another
    room.
    
    In here, kill the Former Human Sergeants and take their Shotguns. Now hit the
    switch in
    this room. The floor it's on will lower, revealing another room. In here, grab
    the Backpack, the Combat Armor, and the Box of Shotgun Shells. When you do,
    backtrack to the level's starting point.
    
    Back down here, go through the middle opening this time. Follow the hall to
    another room. In here, go through the opening to your right. In here, follow
    this hall to a pillar touching the ceiling and the floor. There is a switch on
    this pillar. Hit it, and the pillar will lower, revealing a Medikit. Pick it
    up. Now go in the room in front of you.
    
    In here, there are two openings to the left and right of them, containing
    Former Human Sergeants/Revenants (skill level varies). Kill whatever you see,
    and go
    through each of the four openings. 3 of them contain a Box of Rockets, and the
    other one has a Rocket Launcher. When you grab everything, leave this room.
    
    Back out here, go through the opening just to your left. Follow it to a door.
    When you walk up to the door, turn around. You'll see a wall lower, containing
    two Former Commandos and a Medikit. Kill the Former Commandos, pick up
    their Chainguns, and get the Medikit. Now open the door in you walked up to.
    
    In here, kill the Former Commandos in front of you. See the crates they were
    on? You can lower one of them. Get to the other end of the room, and turn
    around, facing the crates. There is a tan one and a bunch of gray ones. Walk up
    to the tan crate, press the Spacebar, and it will lower. Get on it, and ride it
    to the top. Up here, get the Super Shotgun. When you do, leave this room before
    the Arch-Vile catches you.
    
    Out here, go right. Back in this room, go all the way left, and go through the
    opening. In here, turn right, and head up the stairs. Up here, turn right, and
    kill the Former Commandos. When they're gone, grab their Chainguns, and open
    the only door in this room. In here, go straight to the center of the ledge
    you're on. Now go left and follow this ledge to a room.
    
    In here, kill the Imp, get the Shotgun Shells, and hit the switch. Now leave
    this room, and out here, get to the center of the ledge you're on, and go left.
    The floor in front of you will rise, containing a Revenant. Kill it, then go in
    the room across from you. In here, walk straight to the Red Key, and get it
    before the Former Commandos and the Mancubus get you. Now leave this room
    quickly.
    
    Back out here, go straight into the room across from you, and back out here, go
    down the stairs. Back out here, go through the opening just to your right.
    Follow it to a door. Open it. In here, get to the other end of the room, and
    open the Red Door. Once you do, hit the switch in front of you, and turn
    around. You'll see a pillar lowering containing the Blue Key.
    
    When you get it, *run* to the door across from you. Open it, killing any Heavy
    Weapon Dudes in your way. Back out here, go left, then go through the opening
    to your left. In here, head up the stairs. At the top, go right, through the
    opening. In this room, get the Box of Rockets, and open the Blue Door. In here,
    follow this hall to another Blue Door. Open it.
    
    Over here, kill the Mancubi in front of you (or avoid them if you can) and get
    to the exit teleporter.
    
    -----------------------
    Level 2: Well of Souls
    -----------------------
    
    When you start the level, hit the only switch in the room you're in. The floor
    you're on will lower, and as it lowers, kill the two Former Commandos you'll
    see. Once the floor stops lowering, you should find two openings. Take the one
    to the right. In here, go left, and you should see an opening containing a
    Medikit, a Box of Shotgun Shells, and a Super Shotgun. Grab everything.
    
    Now, turn around, and kill the Former Commando in front of you. Go straight,
    get in front of the opening, and get the Box of Bullets to the right of it. Now
    go in the opening. In here, go in the opening to the left. In here, you should
    see skull heads to the left and right of you (some of them are switches). From
    where you are, get to the second skull head to the left, and press the
    Spacebar. The wall to the right of you will lower, revealing Hell Knights.
    Kill the Hell Knights. When they're all gone, get to the other end of this
    room. Over here, hit the switch to the right (it's a skull head). The wall
    you're on will lower. Down here, kill the Former Human Sergeants, the Former
    Commandos,
    and the Baron of Hell. When they're all dead, collect the Shotguns and the
    Chainguns, collect the health and ammo down here, and go through the only
    opening in this room.
    
    Before you do go in the opening, watch out. There are crushing ceilings in
    front of you, so proceed carefully. At the end of this hall, you'll get to an
    opening. Once you get to it, go straight, and drop down to the floor in front
    of you. Down here, kill all the Demons in front of you, and when they're all
    gone, go through the opening in this room.
    
    In here, kill the Former Commandos in front of you, and go straight. In this
    part of the room is a staircase. Follow it to the top, killing any Heavy Weapon
    Dudes or Revenants in your way. At the top, go through the opening, and in this
    room, get the Yellow Key in front of you, and avoid the Revenants to your
    right. Once you get the Yellow Key, drop down to the floor to your right.
    
    Down here, go through the only opening. In here, get the Medikit, and go in the
    teleporter. When you teleport, go straight, and open the door. In here, go
    straight, through the opening, and get to the other end of the room. Over here
    again, drop down to the floor below you.
    
    Now that you got the Yellow Key, hit the switch on the pedestal. Once you do,
    take the teleporter in here. Back over here, go straight, and head in the
    opening to your right. Back in this same hall, head in the opening to your
    left. In here, go right, through the opening, and in here, kill the Former
    Human Sergeant
    and get the Red Key. Once you have the Red Key, get back in the hallway.
    
    Back in this hall, go right, through the opening. Now go left to a wall, then
    go in the opening to your right, and in here, head up the stairs. At the top,
    go through the opening, and in here, turn left. You should see a silver wall
    with computers on it.
    
    Take out your Pistol, either Shotgun, or a Chaingun. Now shoot the computer
    wall. Turn around. You should see two "guide posts" rise near the edge of the
    platform you're on. It shows that there is an invisible bridge in this room
    leading to the other end of the room. Get in the middle of the "guide posts",
    and go straight, crossing the gap (you're on an invisible bridge).
    
    Using this invisible bridge, cross it to the other end of the room. Over here,
    kill the Revenants in front of you, and go all the way left. Over here you
    should see a pedestal with a switch on it. Hit it. Now go through the new
    opening to your right. In here, follow this hall to a switch. When you get to
    the switch, hit it. The floor you're on will rise.
    
    Up here, kill the Former Commandos and get their Chainguns. Also you can see
    a gap in this room. Drop down to the gap, and down here, collect the health
    Bonuses and the Backpack. Down in this gap is a staircase. Use it to get back
    up here. Now, take the exit teleporter.
    
    ---------------
    Level 3: Aztec
    ---------------
    
    You start the level standing on a bunch of useful goodies. Go straight, and
    *run* to get in the opening across from you. In here, go left, and head up the
    stairs. At the top, get the Armor and health, and turn around. Now head back
    down the stairs, and follow them to an opening. Once you get to the opening, go
    through it. In here, go in the opening across from you, and follow this hallway
    to another room. When you get to the new room, walk forward and the floor in
    front of you will rise, revealing an Arch-Vile. Kill it.
    
    When the Arch-Vile is dead, walk up to the Box of Rockets in this room, and
    then a wall to the left of you will open. Now go through the opening, and head
    up the stairs. At the top, kill the Former Commandos in front of you, and go
    through the opening across from you. Follow this hallway to another room. When
    you get to the new room, turn left. You'll see a huge gap in front of you.
    In the middle of the gap is an invisible bridge (it's in between the torches).
    Cross the invisible bridge to get to the other end of the room. When you get to
    the other end of the room, kill the Former Commandos in front of you. Also in
    this room, hit the switch, and the wall it's on will lower.
    
    Once the wall lowers, get on the new floor. The wall will rise to the top
    again. Once it does, get the Medikit and hit the switch up here too. Now turn
    around. You'll see the Blue Key in mid-air (it's on an invisible platform).
    Back up, and *run* to get on the invisible platform. Get the Blue Key.
    Once you have the Blue Key, drop down to the floor below you, and cross the
    invisible bridge. Use it to get to the other end of the room. Over here, go
    through the new teleporter. When you teleport, kill the Arachnotron next to
    you. When she's dead, go through the only opening up here. In this hallway,
    follow it until you see a switch to the left wall. Hit it.
    
    When you hit it, turn around, and kill the Former Commandos. Get their
    Chainguns, and go right, back into the room we teleported to. Over here, take
    the teleporter. Back over here, go through the only opening near you. Follow
    this hall way to a room. Over here, go down the stairs in front of you. At the
    bottom, go through the opening across from you. Follow this hall to a room. In
    this room, go through the opening to your right. In here, follow this hallway
    until you see an opening to your left (ignore the floor that drops). Once you
    get to the opening to your left, go in it.
    
    In here, follow this hallway to a room. Kill the Former Human Sergeants in
    front of you.
    See the Red Key in the middle of the room? Get on the ledges to the left and
    right of it, and *run* to get on the platform. Get the Red Key. Now exit this
    room before you're caught in an Arch-Vile/Baron of Hell jam.
    
    Back in this hall, follow it to the other hall. Back in here, go left, and
    follow this hall to a room. In here, cross the bridge in front of you to an
    opening. Go through the opening, and watch out for the Revenant that pop up.
    Kill them. Also in this room, there are two teleporters. One has Red Lights
    around it and one has blue lights around it. Go in the teleporter that has Red
    Lights in it.
    
    In this room, follow the hall to a switch. Hit it. Now turn around and go
    through the teleporter. Back in this room, go through the teleporter with Blue
    Lights. In this room, kill the Revenant, and hit the switch in this room
    (collect the Medikits near it). Now turn around. You'll see a pillar on the
    exit teleporter lowering, allowing you to get to the exit teleporter.
    
    Back up, and *run* across the gap to the exit teleporter.
    
    ---------------
    Level 4: Caged
    ---------------
    
    When you start the level, turn around. You'll see a switch. Walk up to it, and
    hit it. Now go through the new lowered teleporter next to you. When you
    teleport, hit the switch in front of you. The floor you're on will lower. Now
    walk straight until you see an opening to your left. Go through it. In here,
    follow this hall to an opening. Go in it.
    
    In this room, there is a switch on the wall to your right. Hit it. Once the
    switch is hit, the wall to the left of you will open, and there will be a new
    pathway to walk on to your left too. Get on the pathway, and follow it to the
    Yellow Key, killing any Cacodemons in your way. On your way to the Yellow Key,
    pick up the health and Ammo you'll pass.
    
    Once you have the Yellow Key, turn around, and get on the pathway. Use the
    pathway to get back to the switch you hit to create the pathway. Once you're on
    the platform with the switch on it, go through the opening to your right. In
    this room, collect the Berserk and the ammo, and go through the only opening in
    this room (don't worry, the Former Commandos can't attack you yet).
    
    In this opening, go down the stairs. Down here, kill the Revenants, and go in
    the room. In here, hit the switch on the pedestal to the right. When you hit
    it, get the health to the right of the pedestal, and the Box of Shotgun Shells
    to the left of the pedestal. Now leave this room. Back in here, kill the Hell
    Knights and Former Commandos in front of you.
    
    When all of the enemies are gone, collect the Shotgun Ammo in here. Now leave
    this room, going through the other opening. Back out here, go all the way
    straight until you get to an opening to your left. Go through it, and go all
    the way straight to the Yellow Door, killing any Cacodemons or Pain Elementals
    in your way. When you get to the Yellow Door, open it.
    
    In here, get to the other end of the room, and hit the switch over here. When
    you hit the switch, go through either opening to the left or right of you. In
    these openings, kill the Imps in front of you, get the Box of Rockets and the
    Box of Shotgun Shells, and hit the switch in this room. Now, go back through
    either opening, and back out here, go through the Yellow Door, and avoid the
    Barons of Hell too.
    
    Back out here, go all the way straight until you see the exit door (can't open
    it). Just before the exit door is an opening to the left. Go in it. In here, go
    all the way straight and get up to the switch across from you. Hit it. The wall
    it's on will lower, revealing a teleporter. Go through it.
    When you teleport, go straight and get to the edge of the platform you're on.
    Now turn around. See the stairs in front of you? Kill the Revenant on them.
    When it's dead, go up the stairs, and at the top, hit the switch. Now turn
    around. You'll see a wall lower, revealing 3 Mancubi. Go left, grab the
    Radiation Suit, and drop into the pit below you.
    
    Down here, kill each Mancubus, and when they're all gone, go into the opening
    they came out of. In here, get the health and ammo, and get the Blue Key. Once
    you grab all the stuff, turn around. See that Lost Soul on top of the
    teleporter? Kill the Lost Soul, and go through the teleporter.
    
    When you teleport, go all the way straight into the opening. In here, hit the
    switch to your right and the lift to your left will lower. Get on the lift, and
    ride it to the top. At the top, pick up the Combat Armor in front of you. Now
    turn
    around and you'll see that the lift has dropped. Go back down.
    
    Down here again, leave this opening, and go through the teleporter across from
    you. When you teleport, go straight until you see an opening to your left. Go
    through it, and follow this opening to the Blue Door, killing any Barons of
    Hell, Cacodemons, or Pain Elementals in your way. When you get to the Blue
    Door, open it.
    
    In this room, turn left. Over here, drop down to the pit to your right. Down
    here, go up the stairs to your right. At the top, hit the switch. Once you hit
    the switch, turn right. See the platform in front of you? Back up, and *run* to
    get on it. When you get on the platform, turn left, and leave this room.
    Back out here, go straight until you see an opening to your left. Go through
    it, and go all the way straight, and you'll notice the exit door has been
    opened. Go in it. In here, hit the switch in front of you. The walls to the
    right and left of you will lower, revealing Former Commandos. Kill them, and
    by now, the walls should've raised. Hit the switch to lower them.
    
    Now, go through either opening. Follow the Hall to another room. In here, kill
    the Former Human Sergeants in front of you. When they are dead, pick up the
    Shotguns, and
    go through the silver teleporter. In here, hit the exit
    switch.
    
    --------------------
    Level 5: Ghost Town
    --------------------
    
    When you start the level, go straight, through the opening. In here,
    head right. Over here is a pillar with a switch on it. Hit it. The pillar will
    lower, containing a Baron of Hell/Revenant. Kill whatever's there, and go
    through the opening the enemy was blocking. In here, head up the stairs, and at
    the top, go through the opening, and drop down to the floor below you.
    
    Down here, go straight, into the opening across from you. Go up the stairs in
    this opening, and at the top, go in the opening to the left, and follow this
    hall until you see an opening to your right, killing the Former Commandos in
    your way. When you get to the opening to the right, go in it.
    
    In here, go all the way straight. As you go, you'll see the floor rise,
    containing the Spider Mastermind. Either kill it or avoid it, and whatever you
    do, keep going straight and get the Blue Key. Once you have the Blue Key, turn
    around, and exit this room (and avoid the Revenants).
    
    Back out here, go through the opening to the left, and follow this hall to an
    opening. When you get to the opening, go through it, and go left and go through
    the opening across from you. In here, get the Super Shotgun, and go through the
    teleporter. When you teleport, you'll be standing on a Plasma Gun. Now *Run*
    straight to get to the Megasphere on the pillar.
    
    Standing on the pillar, drop down to the right, and go straight until you see
    an opening you your left. Go through it, and head up the stairs. At the top, go
    through the opening to your right. In here, follow this hall to an opening. Go
    in it, and over here, kill the Former Commandos, get their Chainguns, and go
    through the opening to the left.
    
    In here, go through either opening to your left or right. Whatever one you go
    through, follow the hall to another room. When you get to the room, go up the
    stairs in the middle of the room. At the top, go straight, through the opening.
    In here, get in front of the door across from you. Now try to open it. Instead,
    the walls to the left and right of you will open, revealing Barons of Hell.
    
    Kill the Barons of Hell. When they are all gone, facing the door, go left. See
    the opening with the Arch-Vile inside? Kill it. Now get the Medikits, and head
    back into the opening where the Arch-Vile was. Hit the switch inside. Turn
    around, and go straight. Remember the door we try to open? It's open now. Go
    inside, and go through the exit teleporter.
    
    ----------------------
    Level 6: Baron's Lair
    ----------------------
    
    See that skull box in the air in front of you? Beneath it are a Super Shotgun,
    Chaingun, Rocket Launcher, and a Plasma Gun hidden. Collect all of them. Now,
    head down either staircase on this platform. Down here, there are four doors,
    and 3 of them have "flags" to the left and right of them. Open the door with
    has black "flags" to the left and right of them.
    
    In here, head down either staircase to the left or right of them, and follow
    either one to Combat Armor and a Box of Rockets. Now, turn left/right, and
    you'll
    see a pit with a few Mancubi. Kill all of them, and go in the pit they are in.
    Down here, hit the switch. When you hit the switch, walls to the left and right
    of you will open, revealing Arachnotrons.
    
    Kill all of them, and when they are all dead, facing the switch you hit, go
    left, and into the opening. In here, go all the way left and you should see a
    door. Turn around, and you'll see a switch. Hit it, and turn around. The door
    will open. In here, follow this staircase to a door, and watch out for the
    Former Human Sergeants.
    
    When you get to the door, don't go through yet. Wait for the Revenants to come
    near you, and kill them. When they are all gone, go through the door, go right,
    and get the Red Key. Now go through either teleporter in here too. When you
    teleport, leave this room (the entrance is right near you). Back in this
    starting room, open the door with Red "Flags" to the left and right of it (this
    is the Red Door).
    
    In here, kill the Former Commandos to the left and right of you. When they're
    dead, go straight, and blow up the barrels in front of you (stay at a safe
    distance too). Now, Cacodemons and Pain Elementals should start coming to
    attack you. Kill all of them. When the Cacodemons and Pain Elementals are gone,
    drop down to the gap in the middle of the room.
    
    Down here, kill all the Hell Knights. When they are all dead, blow up the
    barrels down here, and get the Blue Key. Now climb up the stairs, and back up
    here, get to the door, and exit this room. Back out here, open the door that
    has Blue "Flags" to the left and right of them (this is the Blue Door). In
    here, hit the switch in front of you, get to the other end of the room, killing
    any Demons in your way.
    
    When you get to the other end of the room, turn around. You should see switches
    to the left and right of you. Hit each, and when you two, leave this room from
    where you came from, killing any Revenants or Demons in your way. Back in this
    starting room, the only door we haven't gone through yet is opened. Get to the
    door, and go through.
    
    In here, kill the Former Commandos, Demons, Spectres, and Revenants in front
    of you. When they are all dead, get to the other end of the room, and head up
    the stairs. Up here, kill the Imps. Also up here there are two openings. One of
    them has a switch inside. Hit it, and go back downstairs. Down here, one of the
    walls is lowering, revealing Revenants. Kill all of them.
    
    When all of them are dead, go in the opening they came out of, and hit the
    switch in this opening. Now turn left, and the other wall will lower, revealing
    a Cyberdemon. Save your game and use your Rocket Launcher or Plasma Gun to kill
    it. When you kill the Cyberdemon, go in the opening it came out of, get the Box
    of Rockets and the Medikits, and hit the switch in here too. It lowers the
    platforms the Former Commandos were on.
    
    When you hit the switch, turn around, and leave this opening. You'll see the
    platforms the Former Commandos were on have lowered. Get to either one (both
    have a switch you need you hit), and when you get to a platform, hit the switch
    you can see. When you hit the first switch, go back into the opening where the
    Cyberdemon came out of, and hit the switch again.
    
    The platforms will lower again. Get to the other platform and hit the switch in
    front of you. Now you have it both switches. Go left/right and head up the
    stairs. Up here, you'll notice a new opening. Go through it, and follow this
    hall to the exit teleporter. Before you start the next level, you get a little
    story:
    ------------------------------------------------------------
    You gloat over the steaming Carcass of the guardian. With its death, you
    wrested the accelerator from the stinking claws of Hell. You relax and glance
    around the room. Damn! There was supposed to be at least one working Prototype,
    but you can't see it. The Demons must've taken it. You must find the prototype,
    or all your struggles will have been wasted. Keep moving, keep fighting, keep
    killing. Oh yes, keep living, too.
    ------------------------------------------------------------
    
    Plus, why are there no Barons of Hell in this level if it's named "Baron's
    Lair"? Nobody knows.
    
    --------------------
    Level 7: Caughtyard
    --------------------
    
    When you start the level, pull out your Plasma Gun or Rocket Launcher, and kill
    all the Mancubi down here (there is some Rocket Launcher ammo here if you need
    any). When all of the Mancubi are dead, two walls in this room will lower,
    revealing lifts. Get to either lift, and lower it, and it will reveal a Baron
    of Hell. Kill it. Now, get on the lift, and ride it to the top.
    
    When you get to the top, get to the east part of the platform you're on (switch
    to your Automap for help), killing any Former Humans or Revenants in your way.
    When
    you get to the east part of the platform you're on, you'll see an opening with
    a staircase. Get in center with the staircase, back up, and *run* straight to
    get off this platform, and to get on the pillar that has the Yellow Key in
    front of you (and the Megasphere).
    
    Once you got the Yellow Key, drop down to the floor below you. Down here, lower
    either lift you're on, and ride it to the top. Once you get to the top, get to
    the west part of this platform, killing any Former Humans or Revenants in your
    way.
    When you get to the west part of the platform, walk up to the Yellow Bars and
    press the Spacebar to remove them.
    
    Now, go straight, and hit the switch in front of you. Turn around, and kill the
    Hell Knight/Former Commando that will teleport in front of you. Get to the
    east part of this platform again, get in center with the stairs, and *run*
    straight to get off this platform. Down here, lower either lift again.
    
    Instead of riding it to the top, you'll see a new bridge across from you. Cross
    the lift and the bridge, and out here, get to the northeast part of this room,
    killing any Arachnotrons in your way. Over here, you should see a gap leading
    to a door. Drop down into the gap, and down here, open the door.
    
    In here, kill the Former Commandos, and go all the way straight, and kill the
    Arachnotron in front of you. Now get to the exit teleporter. Just before you
    step on it, turn around, and get to the other end of the room. Over here there
    are two new openings, containing Former Human Sergeants and Former Commandos,
    and
    useful items. Grab everything you can. Once you do, leave your opening, go
    left/right, and get to the exit teleporter.
    
    ---------------
    Level 8: Realm
    ---------------
    
    When you start the level, go straight and go into the water. When you do, the
    floor you're on will lower. Down here, kill the Former Human Sergeants, get
    their
    Shotguns, and head into the door they were next too. In here, kill the Shotgun
    Guys, get all the Shotgun ammo in here, and hit the only switch in this room.
    When you hit the switch, the lifts to the left and right of you will lower,
    containing Barons of Hell. Kill them both, lower the lifts again, and take
    either one. Ride either one to the top.
    
    At the top, collect the Medikits next to you. Now get to the other end of the
    room, and in here, go through the opening and in here, kill the Hell Knights,
    Pain Elementals, Revenants, and Former Commandos, and get the Plasma Gun just
    after the opening. When all of the enemies are gone, with your back against the
    opening you came out of, go straight, and down in this water, head right, and
    go through the opening.
    
    Follow this hall to another room, killing any Mancubi in your way. When you get
    to the room, turn right and open the door. In here, hit the switch on the
    pedestal. Now, leave this small room, go back through the hall to your left
    (follow it to the other room), and back over here, go through the new opening
    to your right. In here, follow this hall to an opening, killing any Revenants
    in your way. When you get to the opening, go in it.
    
    Up here, head right, and hit the switch to your right. Now, turn left. You'll
    see a wall lower, revealing another opening. Drop down to the water below you,
    and go through the new opening. In here, head through the opening to your
    right, and follow this hall to a wall, killing any Revenants in your way. When
    you get to the wall, there should be a staircase to your left.
    
    Facing the staircase, equip your Fist, Chainsaw, Pistol, either Shotgun, or a
    Chaingun and turn around. See that wall? Shoot it with any gun mentioned above.
    The wall will open, revealing health bonuses. Get them, turn around, and head
    down the stairs. Down here, hit the switch in front of you, and the wall in
    front of you will lower, revealing an opening and a Former Commando. Kill it,
    and go through the opening.
    
    In here, go right and you'll see a pit, and kill any Spectres. When you get to
    the pit, drop down to the floor below you, and down here, go straight and go
    through the opening in front of you. In here, there is a lift to the left and
    right of you on that green building in front of you. Lower either lift, get on
    it, and ride it to the top. Up here, get the Blue Key. Now, Former Commandos
    will start to teleport on the lifts. Kill all the Former Commandos (from both
    lifts), and when they're all gone, ride either lift down.
    
    Back down here, go through the opening to your left. In here, turn right, and
    you'll see a toxic floor in front of you, and barrels in the center. Blow them
    up, and they should kill most of the Former Human Sergeants and the Former
    Commandos on
    the "block steps" that the barrels are in front of, and kill the remains of the
    Former Human Sergeants and Former Commandos. Also, kill the Cacodemons and the
    Pain
    Elementals in front of you too.
    
    When they are gone, *run* to the east part of the toxic pit, and get on the
    "block step" next to you. Slowly, use these "block steps" to get to the switch
    across from you. When you get to the switch hit it, and drop down to the toxic
    pit to your right, and from here, go straight and get to the normal floor. Over
    here, kill the Revenants and when they are dead, lower the lift on this part of
    the room.
    When it lowers, get on the lift, and ride it to the top. Up here, open the
    door, and go all the way straight to the opening across from you. Back in this
    room, head up the stairs to your right and up here, hit the switch to your
    left. Now go through the opening to your right. Back in here, go either left or
    right and you'll see an opening to your left/right. When you see the opening to
    your left/right, go through it, and try to go straight.
    
    As you go straight, an Arch-Vile will pop up. Kill it, and then Revenants will
    start to teleport in front of you. Kill them all and when they are all dead, go
    straight (from where the Arch-Vile came from), and walk up to the exit
    teleporter, and the poll on it will lower. Before you can step on it, wait for
    the poll on it to lower. When it's done lowering, go through the exit
    teleporter.
    
    -------------------
    Level 9: Abattoire
    -------------------
    
    When you start the level, kill the Cacodemon in front of you. When it's dead,
    go straight, and get to the other end of the room. Over here, go right, and
    head through the opening over here. In here, go straight, and pick up the Super
    Shotgun in front of you. Then, the floor around you will lower. Drop down into
    the new gap. Down here, go through the opening, and kill the Demons in front of
    you. Also, go through the teleporter.
    
    In here, go straight, and pick up the Plasma Gun and the Energy Cells in the
    middle of the room. Now, keep going straight, and go up the stairs in front of
    you. Up here, kill the Revenants. When they are dead, hit the two skull head
    switches near you. They will lower a pillar with the Blue Key and raise a
    platform just next to you. Cross the platform, and pick up the Blue Key. Now
    turn around, and *run* all the way straight to the other end of the room and
    get to the teleporter at the other end of the room, before you're caught in a
    major enemy teleporting jam. When you get to the teleporter, go through it.
    
    When you teleport, go through the opening in here. Follow it to a wall (it's a
    lift). When you get to the wall, press the Spacebar to lower it, and when it
    lowers, get on this lift, and ride it to the top. Up here, go through the
    opening, and back in this starting room, follow the right wall to the Blue
    Door. When you get to the Blue Door, open it.
    
    In here, hit the switch on the pedestal in front of you. When you hit it, a
    pathway in front of you will rise from the pit. When it's done rising, cross
    this new pathway, and follow it to two doors (one's a normal door, one's a
    Yellow Door). Open the normal door.
    
    In here, kill the Imps and Mancubi in front of you. When they are all dead,
    take either stairway in here, and at the top of either one, you'll see a
    pathway leading to the center of the room. Cross it to the Yellow Key. When you
    have it, leave this room. Back out here, open the Yellow Door to your left. In
    here, kill the Arachnotrons in front of you. When they are dead, get the Red
    Key in this room. Now leave before the new Spectres and Former Commandos get
    you.
    
    Back out here, cross the pathway to your left. At the end, open the Blue Door
    over here, avoiding the Former Commandos and the Mancubi. Back in here,
    follow this left wall to the Red, Yellow, and Blue bars. Press the Spacebar to
    remove each of them, and go through the teleporter you can now access.
    
    When you teleport, kill the Cacodemons, Imps, Barons of Hell, and Hell Knights
    surrounding you. When you walk around, the platform they're on should lower.
    When they are all dead, walk up to the door in here. Before you open it, turn
    around, and get to the other end of the room. Over here, check the walls until
    one of the walls open, revealing a Soul Sphere. Grab it. Now turn around and
    open the door. Go through.
    
    In here, go straight, and take either pathway to the other end of the room.
    Over here you'll find a pedestal with a switch on it. Hit it, and turn around.
    A platform will be raising to the exit teleporter. While it's raising, kill the
    Imps, Mancubi, and Former Commandos around you before you get killed.
    Once the platform is done raising, kill the Imps on it, and cross it to the
    exit teleporter. Step on it.
    
    --------------------
    Level 10: Onslaught
    --------------------
    
    At the start, go in the cage in the middle of the room and get the Blue Key.
    Now, turn around, and leave this cage. Kill the Cacodemons, Former Human
    Sergeants, and
    Former Commandos in this room, and when they are all dead, grab all the
    health and ammo in this room, and get the Invisibility Sphere next to the
    starting exit teleporter.
    
    Also in this room is a door to the right of the Blue Bars. Open it, and in
    here, hit the switch. Now leave this room. The bars have lowered, and now go
    through the new opening. In here, go all the way left and you'll see an
    opening. Go through it. In here, open the door across from you, and hit the
    switch in front of you (avoid the Baron of Hell). The floor you're on will
    lower.
    
    Down here, kill all the Demons, and head right, and go through the opening. In
    here, go through the opening to your right. In here, kill the Imps and Spectres
    and check the walls to your right from where you entered this hall, and you
    should find a wall that will lower, revealing two Stimpacks and two Box of
    Rockets. Grab everything, and leave this opening. Back out here, go right, and
    you'll see an opening to your left. Go through it.
    
    In here, kill the Hell Knights, get the Medikits, and hit the switch in this
    room. Now leave. Back in here, kill the Imps, Former Human Sergeants, Spectres,
    and
    Demons. With your back against the opening you just came out of, go through the
    opening to your left. In here, go up the stairs to your right, and at the top,
    go through the opening.
    
    In here, kill the Spectre, and grab the Medikits, the Box of Shotgun Shells,
    and the Rocket Launcher. Now go through the opening in this room and go up the
    stairs. At the top, walk up to the pedestal, and it will lower. Before going
    straight, turn around, head down the stairs. Back down here, the pillar with
    the Combat Armor has lowered. Get the Combat Armor and head back up the stairs.
    
    Back up here, walk to the pedestal again, and it will lower. Before you hit the
    switch in this room, go right, through the opening. In here, you'll be in front
    of a staircase leading down (and one leading up). Head down the stairs, get in
    front of the other staircase in front of you, and before you head up those
    stairs, check the walls to the left.
    
    The wall will lower, revealing a Plasma Gun. Grab it, and turn around. Get in
    between the stairs again. Now, check the wall to the left again, and turn
    around. You'll see another wall lower. Go through the new opening, and grab the
    Medikit, Box of Rockets, and an Invisibility Sphere. Grab everything.
    
    Get in between the stairs again, and go left up the stairs. Back up here, get
    the health, ammo, and hit the switch in this room. Now turn left, go down the
    stairs, then up the stairs in front of you, and go through the new opening at
    the top. Back in this room, kill the Revenants, Arch-Viles, and Mancubi in
    front of you.
    
    When they are all dead, get the Yellow Key in the middle of the room. Once you
    get the Key, turn left and get to the wall. Now go all the way left and you'll
    see the Yellow Door. Open it, killing any Imps, Pain Elementals, or Hell
    Knights in your way. When you open the door, go through.
    
    In here, go left, then go left again. Over here, kill the Former Commandos
    and the Arch-Viles in front of you, and when they are dead, go straight and get
    the Red Key. Now turn around, go through the Yellow Door, and leave this room.
    Back out here, kill the Imps, Pain Elementals, and the Revenants in front of
    you. When they are all dead, with your back against the Yellow Door, go all the
    way straight to the other end of the room.
    
    Over here, go all the way right and get to the other end of the room. Over
    here, open the Red Door (it's a switch in between Red Bars). Now kill the
    Former Humans in front of you, and hit the switch it was in front of. Now get
    back
    to the Yellow Door, and open it. Go through.
    
    In here again, you'll notice the Red Door has opened. Go through the new
    opening, and in here, head left. Follow this pathway to the exit teleporter,
    killing any Former Human Sergeants, Barons of Hell, or Hell Knights in your
    way. When you
    get to the exit teleporter, step on it.
    
    -----------------
    Level 11: Hunted
    -----------------
    
    *******************************************************************************
    This will be the most annoying level you'll ever play in your life in Doom.
    This level is a big maze that is filled with Arch-Viles. On Skill levels 1 and
    2, there are a total of 12 Arch-Viles on the map, and 18 on skill levels 3, 4,
    and 5.
    
    To get out of this level, you must go through a series of doors, get a key, and
    hit the switch to exit the level. Note to open ANY of these doors, you must
    walk across a silver line on the walls (you'll see them on the sides of the
    wall too) and a nearby door will be opened. So once you cross silver lines on
    the walls, the doors will be opened. But you do get a nice present for beating
    the level. On with the walkthrough.
    *******************************************************************************
    
    Now, the room you are starting in looks creepy. There are dead marines in
    tombstones to the right, and nothing in here. Walk forward and the wall to your
    left will open, revealing all the Arch-Viles that will appear in the maze (some
    are in a trap at the end of the level). Don't shoot or they will hear and
    attack you. For now, they won't attack you. Collect the Backpack, Boxes of
    Shotgun Shells and the Super Shotgun, now hit the switch on the pedestal and it
    will disappear, revealing an opening and releasing the Arch-Viles. Onto the
    maze.
    
    Out here, turn right and you will see an opening to your right, so go through
    it. In here, go straight and you'll see a silver line on the walls. Walk past
    them and a door to the left will open, so go through it. In here, turn left and
    follow this long hallway until you see a door to your right and left. Watch
    out, there are 2, maybe 3 Arch-Viles in this hall. Once you see a door to your
    right and left, the one to your right should be opened. If not, backtrack to
    the last silver line to open the door, and then go through it.
    
    Out here, turn right and you'll see a long hall. Go straight and follow this
    hallway until you see an opened door in front of you. Once you see the opened
    door, turn left and you'll see another door to the left. If it isn't opened,
    backtrack to the last two silver line sets and walk across them. Now go through
    that opened door (not the one in front of the silver lines). In here, go
    through the opening across from you. In here, turn left and follow this hall to
    the Red Key. Once you get to the Red Key, pick it up. Now turn around and go
    back through the opening. Back in here, walk across the silver lines on the
    wall to re-open the door across from you. Once it is opened, go through it.
    
    Back in here, turn right and follow this long hallway until you stop at a set
    of Yellow Bars, killing any Arch-Viles down this hall. Once you stop at a set
    of Yellow Bars, turn right and you'll see a switch. You need the Red Key to hit
    this switch, so hit it (there is a Yellow Key, but getting the Red Key is
    faster). Once you hit the switch, turn right. Now follow this same hall back
    until you get to 2 silver line sets and a door. Walk up to the door to open it,
    and then go through it. In here, go straight and you'll see an opening to your
    right, so go through it. In this opening, turn right and you'll see a door.
    
    To get to the silver line set of this door, face it and go through the opening
    to your left. In here, go through the opening in front of you and you'll see a
    silver line set to the left. Step over it and then RUN back to the opened door,
    and then go through it. In here, turn left and follow this hallway until you
    get to another opened door (it will be opened by the time you get there). Once
    you get to it, go through it. You'll be near the level's starting point now.
    Now turn left and follow this path until you see a door to your left. Once you
    see the door, the silver line set for it is just ahead. Walk across it to open
    the door, and then go through it.
    
    In here, kill any Arch-Viles that you may see. Now go through the opening to
    the left and the door behind you will open, so go through it. In here, go
    through the opening in front of you. In here, turn left and follow this twisted
    hallway until you get to the same set of Yellow Bars you saw earlier. Now that
    the Red Bars are opened, you can get to a teleporter. Before stepping onto it,
    get the Box of Shotgun Shells and the Berserk. Now step through the teleporter
    AND YOU ARE NOW OUT OF THE MAZE! PARTY TIME! Save your game because you'll
    never want to go through that maze again.
    
    Out here, get to the other end of this area and you'll see a spiral staircase.
    Each stair has a health potion on it, so there are 15. Get to the top to find a
    *GASP* BFG9000! That is your nice reward for beating the maze. You must get it
    to exit the level. Now once you have the BFG and have fallen off the staircase,
    a square wall around you will lower, revealing a teleporter. Step onto it. Once
    you are teleported, you'll see an exit teleporter to your left and right. Pick
    your poison now. The left teleporter allows you to exit the level. The
    teleporter on the right takes you to a trap where the remaining Arch-Viles are.
    They will try to kill you but you'll escape with 1% health. So take the left
    one and you're done. WOO HOO!
    
    Now, before you enter the level, you get a little story:
    ------------------------------------------------------------
    Even the deadly Arch-Vile Labyrinth could not stop you, and you've gotten to the
    prototype accelerator which is soon efficiently and permanently deactivated.
    You're good at that kind of thing.
    ------------------------------------------------------------
    
    ----------------
    Level 12: Speed
    ----------------
    
    When you start the level, pick up the Chaingun behind you. Imps will appear.
    Kill them all. When they are all dead, grab the health and ammo in this room.
    Now drop in the pit in this room. Down here, get the Super Shotgun, and open
    the door, and go through. In here, kill the Cacodemons and Hell Knights in
    front of you. With your back against the door, go through the opening to your
    left. In here, follow this hall until you get to a gap. When you see the gap,
    drop down.
    
    Down here, go left, and go through the opening across from you, killing any
    Former Human Sergeants, Imps, or Former Commandos in your way. When you go
    inside the
    opening, head right up the stairs. Up here, kill the Mancubus, and grab the
    health, ammo, and the Yellow Key. Now, go through the only opening in this
    room, and follow it to another opening, killing the Hell Knight in your way.
    When you get to the opening, go through. In here, kill the Former Commando,
    and with your back against the opening you came out of, turn right. You'll see
    another opening.
    
    Get in center with the opening, and *run* straight, going through. You should
    land on a teleporter. When you teleport, kill the Former Human Sergeant near
    you, and get
    on the platform he was on. On this platform, go through the opening, and follow
    it to another opening, killing any Imps, Former Human Sergeants, or Former
    Commandos in
    your way. When you get to the opening, go through.
    
    Don't drop to the pit. Instead, drop down to the platform just to the left of
    you, collect the health, and take the teleporter. Over here, kill the Hell
    Knights and the Former Commandos, and open the door on this platform. In
    here, hit the switch in front of you. Now turn around, go straight, and drop
    down to the pit below you. Down here, go all the way straight, and go in the
    opening across from you, killing any Cacodemons or Pain Elementals in your way.
    In the opening lower the lift.
    
    When the lift finished lowering, get on it, and ride it to the top. Up here,
    kill the Revenants and the Mancubus. When the are all dead, go through the
    opening to the right. In here, go all the way straight to the other end of the
    room. Over here, hit the switch on the pedestal, turn around, and kill the
    Former Human Sergeants and Former Commandos in front of you.
    
    Now turn back around. See the Cyberdemon on that platform? Unload your Rockets
    and Cells and kill him. When he's dead, get in center with the platform he was
    on, and *run* straight to get on the platform. On here, get the Red Key. Now
    drop down in the pit. Down here, go through the opening again, and in here,
    lower the lift, get on it, and ride it to the top.
    
    Up here again, go through the opening to your right. In here, head up the
    stairs to your left and at the top, follow this hall to the Blue Key. When you
    have the Blue Key, turn around and go straight. You will be teleported. Up here
    there are 4 alcoves and 2 Arch-Viles teleport non-stop to each alcove (very
    fast). Kill them both, and when they are both dead, hit all 4 switches from
    each alcove.
    
    Now drop down to the pit. Back down here, go through the opening, lower the
    lift, get on it, and ride it to the top. Up here, go through the opening to the
    left. In here, go straight, killing any Revenants in your way. In this room, go
    through the opening to your left, and follow this hall to another opening. Go
    through it. In this big room, head all the way left to the switch. Hit it, and
    the wall it's on will lower.
    
    Now hit the next switch in front of you. Then turn around and wait (try to
    avoid the Former Commandos). There is a pathway to your left rising to a
    platform. When it is finished rising, cross it, and hit the switch in front of
    you (it's a door, and it will open). Kill the Arch-Vile in front of you, get
    the BFG, and hit the switch in front of you too. Leave this little room.
    Out here, a new pathway is rising. When it's done rising, cross it to another
    platform, and over here, kill the Revenants and the Arch-Vile in the opening.
    When they are all dead go through the opening, and hit the switch in front of
    you. Turn around and leave this little room.
    
    --------------------
    Level 13: The Crypt
    --------------------
    
    When you start the level, kill all the Lost Souls around you. Now get the
    health and ammo in this room. See the door in here? Hit both switches next to
    the door. The door will now open. Go through. In here, get the Yellow Key in
    the middle of the room. 4 pillars in here will lower, revealing 4 Mancubi. Kill
    all of them, and get the health, ammo, and armor in this room.
    Now, facing the Blue Bars in this room, open the Yellow Door to your right. In
    here, follow this pathway to an opening. In here, kill the Hell Knights, and go
    straight. Over here, walk around, and the floor you're on should lower. Down
    here, go right, then right again. Over here you'll see two openings. Go through
    the one on the left. In here, head up the stairs to your right.
    
    Up here, kill the Former Human Sergeants around you, collect their Shotguns,
    and go
    through the opening. In here, go straight until you see an opening to your
    right. Go through, and then you'll see Former Commandos and an Arch-Vile.
    Kill all of them, and get the Former Commando's Chainguns. Now, go through
    the opening across the lava pool.
    
    In here, hit the switch. Now go back through the opening. In the lava pool, see
    the little pit to the left? Go to it, and drop down it. Down here, go all the
    way left, and you should come across a teleporter. Step on it, and you'll be
    teleported. You should telefrag a Former Humans. Anyways, kill it, and get the
    Blue
    Key. Now drop down to the floor below. Down here, go all the way left until you
    get to a wall, killing any Cacodemons, Hell Knights, Barons of Hell, or
    Arachnotrons in your way.
    
    Now, turn right. You should see an opening to the right. Go in it. In here, hit
    the switch, and it will lower the lift, then get on it, and ride it to the top.
    Up here, follow this pathway back to the Yellow Door. Open it. Back in here,
    open the Yellow Door across from you. In here, go left, and open the Blue Door
    (don't worry, the floor isn't poisonous), and kill the Baron of Hell in front
    of you. In here, hit the switch in front of you.
    
    Now, turn around and leave this room. Back in this room, turn left. You'll see
    that the Blue Bars have been lowered. Go through the new opening that's been
    revealed. In here, kill the Former Commandos, and go through the opening to
    the left. In here, kill the Former Humans and the Former Commandos, and hit the
    switch on the pedestal in the middle of the room. The bars surrounding the exit
    teleporter in front of you will lower.
    
    Go straight, and step on the exit teleporter.
    
    ------------------
    Level 14: Genesis
    ------------------
    
    When you start the level, go through either opening to the left or right of
    you. Whichever one you go through, follow it to another opening. When you get
    to the opening, go through it. In here, go in the opening to the right. In
    here, head up the stairs to the left. At the top, collect the Box of Shotgun
    Shells, and head right. See that opening? Back up, and *run* straight to get
    through the opening (there is a gap).
    
    Over here, go all the way straight to the other end of the room, killing any
    Revenants in your way. When you bump into a wall, turn right, and kill the
    Revenant in front of you. Now, go straight until you see an opening to your
    left, killing the Former Human Sergeant in your way. When you see the opening
    to your
    left, go through it.
    
    In here, follow this pathway to the two Medikits and the Invisibility Sphere.
    Now turn around. The pathway is lowering. Also part of the wall in front of you
    is lowering, revealing a staircase. Drop down to the pit, go straight, and head
    up the stairs. Up here, head right, and follow this platform to a switch,
    killing any Revenants, Former Human Sergeants, Hell Knights, Mancubi,
    Cacodemons, or
    Former Commandos in your way. When you get to the switch, hit it.
    
    The pathway is rising again. Drop down to the pit below you and step on the
    teleporter. You'll be teleported back to the pathway. Follow it back to the
    opening. Go back through. In this hall again, head left, and follow this hall
    to an opening to the right. When you see it, go through. In here, cross this
    pathway to the Yellow Key. When you have the Yellow Key, keep going straight,
    and drop down in the gap below you, killing any Cacodemons, Arch-Viles, or
    Former Human Sergeants in your way.
    
    Down here, go straight to the other end of the room, killing the Former Human
    Sergeants,
    Revenants, and Arch-Viles in your way. Over here, open the Yellow Door. In
    here, blow up the barrels, and kill the Former Commandos in front of you.
    Now, take either teleporter. Up here, head right, and go through the opening.
    In here, follow this hall to the exit teleporter, killing any Imps or Revenants
    in your way. When you get to the exit teleporter, step on it.
    
    -----------------------
    Level 15: The Twilight
    ----------------------
    
    There are plenty of secrets here you won't want to miss, so I'll guide you
    through them.
    
    When you start the level, take the teleporter in front of you. When you
    teleport, hit the switch on the wall in front of you, and the floor you're on
    will lower like a lift. Down here, go all the way right until you see a part of
    a wall to your right in between the bars. Once you see it, check it, and it
    should open like a door. In here, go straight and hit the switch in front of
    you (so you'll get credit for a secret). Now, go turn right and you should see
    a new opening across from you. Go in it.
    
    In here, kill the Former Commando in the cage to your right, and save your
    game (in case you fall in the lava pit, there's no way out of it). Also, kill
    the Revenants on the higher platform to your right. See those pillars leading
    to the platform? Cross all of them to the platform the Revenants were on (each
    pillar you step on counts as a secret!!!). On the platform, get the Megasphere,
    go back down the pillars, go right, and leave this room.
    
    Back out here, go all the way straight until you get to a Rocket Launcher
    (where the Rocket Launcher is, call this the middle pathway, and don't get the
    Rocket Launcher yet). Facing the Rocket Launcher, go right until you get to a
    door. WATCH OUT FOR THE PESKY HELL KNIGHTS AND REVENANTS THAT'LL TELEPORT IN
    FRONT OF YOU!!! The BFG should make short work of them. When you get to the
    door, open it, and go through. In here, get the Yellow Key in front of you.
    Now, turn back around, and leave this room. Back in here, kill any more enemies
    that teleported in front of you.
    
    Now, get back to the middle pathway. Facing the Rocket Launcher, turn around.
    See that small opening in between the staircase in front of you and your right?
    Go through it. Down here, take the teleporter. When you teleport, get all the
    health, armor, and ammo in this room. Also, there is a hidden teleporter in the
    southern part of this room. So check the walls until you find a hidden door
    revealing a teleporter. When you find it, take it. When you teleport, kill the
    Mancubus in front of you (or if you already telefragged it), and get the Box of
    Rockets and the Medikit. Now, open the door to your left, and go through.
    
    In here, get the Box of Shotgun Shells and the Invisibility Sphere, then take
    the teleporter. When you teleport, you'll be back at the middle pathway. Turn
    left to face the Rocket Launcher. Without grabbing it, drop down to the pit in
    front of you (try to drop down to the left). Down here, take the teleporter to
    your left. When you teleport, check the wall to your right and a hidden door
    should open, revealing a BFG. Grab it, then leave this secret room. Back in
    here, get the Energy Cell Pack, the Plasma Gun, and the Soul Sphere in front of
    you (man, this place has awesome stuff).
    
    Now turn left to face an opening. See that Hell Knight on the pillar? Kill it,
    then save your game. Pull out a small weapon so you can see the pillar. Now,
    *run* forward to get on it (if you miss, load up your saved game). On the
    pillar, drop down to the pit below you (not to the lift, you may get in a
    teleporter). Down here, go through the new opening to your lift (the pillar you
    landed on opens up this opening). In here, grab the Invincibility Sphere, turn
    back around, and go through the teleporter.
    
    You'll be teleported back to the center pathway. Now turn around, and go all
    the way straight until you get to a switch (kill any Former Commandos around
    you). When you get to a switch, hit it, and a pathway will rise to your left.
    Cross it to a switch, and hit the switch. It will open like a door, so go
    through. Now, hit the switch in front of you. Once you hit the switch, run like
    mad back to the center pathway, killing any Arch-Viles, Former Commandos,
    Cacodemons, or Pain Elementals in front of you.
    
    By now your Invincibility should be wearing off. Back at the center pathway,
    turn left to face the Rocket Launcher. Facing it, head up the stairs in front
    of you. At the top, get the Megasphere, and ignore the Spider Mastermind on
    hard skill levels. Now continue all the way straight, but DON'T GO IN THE
    TELEPORTER you'll see. Instead, check the wall to the left of it (not the
    bars/cages) until the wall lowers, revealing another teleporter. Now, back up,
    and *run* straight to get to that teleporter.
    
    When you teleport, open the door in front of you. In here, kill the Heavy
    Weapon Dudes, get their Chainguns, get the Energy Cell Packs, and step on the
    exit teleporter (this takes you to the secret exit ;)).
    
    Before you start the next level, you get a little story:
    ------------------------------------------------------------
    You've found the second hardest level we got. Hope you have a Saved Game a
    Level or Two previous. If not, be prepared to die aplenty. For master marines
    only.
    ------------------------------------------------------------
    
    -------------------
    Level 31: Cyberden
    -------------------
    
    This is one of the coolest secret levels in the world of Doom. The starting
    area has 4 cages. Each of them have a Cyberdemon, but none of them can see you.
    Even if you fire your weapon, they won't hear you at a time. You release one at
    a time to kill them off, and you must solve easy puzzles.
    
    When you start the level, go all the way straight to the other end of the room.
    Over here, head down the stairs, then go up the stairs in front of you. Up
    here, get the Super Shotgun and the two Medikits, and go through the opening to
    your right. In here, head up the stairs to your right. At the top, go all the
    way straight, and over here, head down the stairs to your right. At the bottom,
    get the Rocket Launcher, and the Boxes of Shotgun Shells, and hit the switch on
    the demon head. Now backtrack all the way to the level's starting point (avoid
    the Hell Knights).
    
    You'll see that one of the Cyberdemon cages have been lowered, revealing a
    Cyberdemon. Kill the Cyberdemon, and go to the cage where it came out from.
    Over here, get the Boxes of Rockets, and hit the switch. The door next to you
    will lower. Now go through the new opening. In here, get the Boxes of Rockets
    and the Medikits, and hit the switch in here. Now leave this room. Out here,
    get back to the room where we saw all those Hell Knights. Back in that room,
    kill all the Hell Knights.
    
    Also, in the northeast corner of this room, there is a new opening. Go through
    it. In here, kill the Spectres, and get the Box of Shotgun Shells. Also, hit
    the switch on the Demon Head picture. Now, backtrack to the level's starting
    point again. You'll notice that another Cyberdemon has been released from its
    cage. Kill it, and go to the cage it came out of. Over here, collect the Boxes
    of Rockets, and hit both switches. Now go through the new opening.
    
    In here, hit the switch at the other end of the room. The floor you're on will
    lower. Down here, hit the switch to your right (and kill the Baron of Hell in
    front of you). When you hit the switch, get back on the lift, wait for it to
    rise again, and now leave this room. Now, go back where we killed the Hell
    Knights again. Back in here, go through the same opening in the northeast part
    of this room. In here, go through the new opening to your left. In here, kill
    the Former Commandos, get their Chainguns, get the health and the BFG, and
    hit the switch on the Demon Head picture.
    
    With the switch hit, head back to the starting room again. Another Cyberdemon
    has been released. Kill it, and go to the cage it came out of. Over here,
    collect all of the Boxes of Rockets, and hit both switches. The door next to
    you will open. Go through. In here, get to the other end of the room and hit
    the switch, avoid the Mancubi at first (when you hit the switch, kill them).
    Now, when you hit the switch, turn around and leave this room. Back out here,
    get back to the room where all those Hell Knights were.
    
    In this room again, go through the new opening in the northwest corner of the
    room. In here, head down the stairs in front of you. At the bottom, kill the
    Former Commandos to the left and right of you, get the health in here, and
    hit the switch on the Demon Head picture in this room. Now leave this room, and
    backtrack to the starting room again. Another Cyberdemon has been released.
    Kill it, and go to the cage it came out of. Over here, collect the Boxes of
    Rockets, and hit both switches. The door will now open. Go through.
    
    In here, kill all of the Former Commandos in front of you, and then head up
    either staircase to the left or right. At the top, go through the opening in
    front of you. In here, go left, and follow this hallway to a switch (get the
    Berserk too). Hit the switch, and get back to the door we used to enter this
    room, killing any Demons in your way. When you get to the door, hit the
    switches to the left and right of it. The door will now open. Leave this room.
    
    Back out here, get to the middle of the room, and climb up the spiral stairs to
    the top of the pillar. When you get to the top, get the Yellow Key. Now jump
    off the pillar, and open the Yellow Door across from you. Go through. In here,
    step on the silver teleporter. When you do, the walls around you will lower,
    revealing Boxes of Rockets. Grab all of them, and leave this room. You'll see a
    LOAD of Revenants coming at you. Kill all of them, and when they are all dead,
    with your back on the Yellow Door, go through the new opening to your left.
    
    In here, hit the switch in front of you. Now turn around and get to the other
    end of the room. Over here, go through the opening to your right. In here, step
    on the exit teleporter.
    
    Before you enter the next level, you get a little story:
    ------------------------------------------------------------
    Betcha wondered just what was the hardest level we had ready for ya? Now you
    know. No one gets out alive.
    ------------------------------------------------------------
    
    ------------------
    Level 32: Go 2 It
    ------------------
    
    Oh boy, this is going to be a fun one. When you start the level, pick up ALL
    the weapons in front of you, and go through the opening to your left. In here,
    pick up the BFG and its ammo in front of you, and the walls around you will
    lower, revealing tons of Mancubi. Kill all of them, and from where the BFG was,
    go all the way left, and go through the opening in front of you. In here, go
    left, and go through the opening in front of you. Out here, kill the Cyberdemon
    in front of you, and go back through the opening.
    
    In here, go left, and kill the Arachnotron in front of you, and go through the
    opening she was in front of. Now follow this hall to an opening, and go
    through. Out here, go all the way straight, and kill the Arachnotrons and the
    Spider Mastermind in front of you. When all of the enemies are gone, get to the
    pillar on the middle of this platform. Hit the switch on this pillar, and it
    will lower. When it's done lowering, get the Yellow Key.
    Now, turn around, go straight, and jump off the platform. Down here, go all the
    way straight, and get to the left of the opening in front of you. Over here (to
    the left of the opening), check the walls until a hidden door opens. When it
    opens, go through. In here, turn left, and kill the 2 Arch-Viles. Now, go
    straight to the other end of the room, and go through the opening to your right
    (you'll notice that this area is a replica of Level 1 in Doom II).
    
    Kill the Mancubus in front of you, and follow this hall to an opening. Over
    here, turn right, and kill the Cyberdemon in front of you. Now, open the Yellow
    Door it was in front of. In here, kill the Cyberdemon in front of you, get all
    the Boxes of Rockets, and get the Red Key. Now turn back around and go through
    the opening to the left. From here, backtrack to where the secret door was.
    Open it again. Back out here, go through the opening to your right, and in this
    room again, go through the opening to your left, and follow this hall to an
    opening, and go through it.
    
    Back in here, kill ALL the Revenants, Arch-Viles, Arachnotrons, and Cyberdemons
    in front of you. Now, go all the way straight to where the Yellow Key was, and
    now head up the stairs to your right. Up here, get the Blue Key in front of
    you, go straight, and drop down off the platform. Back down here, open the
    secret door in front of you again. In here again, go back through the hall that
    the Yellow Door was in. Facing the Yellow Door, turn around, go straight, and
    open the Blue Door in front of you, killing any Revenants or Former Commandos
    in your way.
    
    When you open the door, kill the Cyberdemon in front of you, and hit the switch
    it was in front of. Now turn around, and leave this opening. Now, turn right.
    You'll see an opening to your right. Go through it. In this room, go all the
    way straight to the other end of the room, ignoring the Arch-Viles,
    Cyberdemons, and Barons of Hell you'll see. When you get to the other end of
    the room, open the Blue Door in front of you. Now open the Red Door, then the
    Yellow Door. In here, step on the exit teleporter.
    
    -------------------
    Level 16: The Omen
    -------------------
    
    When you start the level, head down the stairs in front of you. At the bottom,
    head all the way left, onto the Toxic Floor (don't worry, it's not poisonous).
    In here, go all the way straight. Over here, you should see a lift rising and
    raising on its own (you can't lower it). When it lowers, go all the way
    straight (don't ride the lift). Over here, get the Blue Key. Now, turn back
    around and if the lift is still lowered, get on it, and ride it to the top. Up
    here, head all the way left until you get to an opening, killing any
    Cacodemons, Former Human Sergeants, and Former Commandos in your way.
    
    When you get to the opening, go through it. In here, kill the Heavy Weapon
    Dudes in front of you, and get to the other end of the room. Over here, get the
    Red Key. Now, turn around, and go straight, killing any teleporting Revenants
    in your way. Back out here, drop down to the non-toxic toxic floor below you.
    Down here, go all the way left and get both Shotguns and the ammo, and open the
    Blue Door near you too. In here, get to the other end of the room. Over here,
    get the Yellow Key, turn around, and leave this room, killing any Spectres and
    Arch-Viles in your way.
    
    Back out here, get to where the Blue Key was. Over here, open the door to your
    left, killing any Revenants, Mancubi, or Arch-Viles in your way. In here, kill
    ALL the Former Commandos and Former Human Sergeants in front of you. When all
    of them
    are dead, walk to the center of the room, and turn right. You'll see platforms
    rise and drop. Get on one of the platforms that is rising, and when it finishes
    rising to the top, look right. Cross across the platforms until you see an
    opening to your right. Go through it.
    
    Over here, open the Red Bars, and hit the switch in front of you. Now turn
    around, and drop down to the floor below you. Down here, take the teleporter in
    the middle of the room. When you teleport, go straight, and take the exit
    teleporter.
    
    -------------------
    Level 17: Compound
    -------------------
    
    You better have a decent amount of health when you start this level, otherwise
    you'll be in serious ****.
    
    When you start the level, walk into the toxic pit in front of you. In here, hit
    the switch. To the left is a wall opening, revealing an opening. Go through it.
    In here, kill the Imps on the platform, and take the stairs to get to the
    platform. Up here, get the health, the Super Shotgun, and the Radiation Suit.
    Now, once you get the Radiation Suit, drop down to the toxic floor. Down here,
    turn around. You'll see two openings. Go through the one on the right. In here,
    kill the Former Commandos on the platforms.
    
    Now, from the opening you came out of, head straight. You'll see 3 openings to
    your right blocked by barrels. Destroy the barrels to clear the way. But, you
    can't reach the openings yet, so turn right, facing the opening. You'll see a
    switch to the right of it. Hit it, killing the Spectres in your way. Now, turn
    around. Use either platform in front of you to get to a higher platform.
    Whichever one you go on, follow it to an opening. Get in center with the
    opening, back up, and *run* straight to get to the opening. In here, kill the
    Former Human Sergeants, and head all the way left.
    
    Over here, follow this hallway to the Red Key, killing any Hell Knights,
    Former Humans, or Former Human Sergeants in your way. When you have the Red
    Key, backtrack
    all the way back to the opening you used to enter this room. Go back through
    it, and head in the slime pit. Now go left, and go through any of the 3
    openings that were blocked by barrels. In here, go straight. You'll see 3 more
    openings blocked by barrels. Blow up all the barrels, and with your back
    against the opening, head left and get on the normal floor. Over here, open the
    Red Door.
    
    In here, head upstairs. At the top, follow this hall to an opening to your

    Arachnotrons
    in your way. When you see the opening to your left, go through it. In here, go
    left, and hit the switch in front of you. Now leave this room (watch out for
    the Imps teleporting at you). Back out here, follow this hall to the right
    until you see an opening to your left. Go through it. In here, *run* across the
    platforms until you get the Yellow Key.
    
    With the Yellow Key, open the Red Door again. Back in here, follow this hall
    until you get to a switch, killing any Imps, Arch-Viles, or Barons of Hell in
    your way. When you get to the switch, hit it. Now backtrack back to the hall
    that lead to the Red Key. Instead of going back to the Red Key, with your back
    against the opening that leads to the slime pit, go through the opening across
    from you. In here, take the exit teleporter.
    
    ----------------------
    Level 18: Neurosphere
    ----------------------
    
    When you start the level, *run* straight to get to the opening/room across from
    you before you're caught in a Imp/Former Human Sergeant jam (they teleport
    right to you,
    and kill the Imps and Former Human Sergeants in your way too). In here, head up
    the
    stairs to your left. At the top, kill the Imps and the Former Human Sergeants
    in front of
    you. Now go all the way straight until you see a window. Go through it, and you
    will drop down to the ground below you.
    
    Down here, head left until you see a staircase to your left, killing any Heavy
    Weapon Dudes in your way. When you see the staircase, head up it. Up here, kill
    the Former Commandos in front of you, and get the Plasma Gun up here. Now
    turn around, and face the opening. From here, kill the Revenant and the Heavy
    Weapon Dudes in front of you. When they are dead, get in center with the
    opening, and *run* straight, passing the opening, onto the platform in front of
    you (should be gray).
    
    When you get on this platform, head right, and head up the stairs in front of
    you. At the top, kill the Former Human Sergeants and Imps in front of you, and
    also get
    the Red Key. Now turn around and head back down the stairs. Down here, get back
    on the platform to your left (kill the Former Commandos around you too). On
    the platform, go straight, and head through the opening across from you. Back
    in here, go all the way right until you get to the Red Door, killing any
    Former Humans, Imps, Former Human Sergeants, Arch-Viles, or Former Commandos in
    your way.

    have lowered. In here, head up the stairs, go straight, and go through the
    opening to your left. In here, kill the Hell Knights, Arch-Viles, Revenants,
    and Former Commandos in your way. When they are all dead, get the Blue Key.
    Once you have the Blue Key, turn around, go right, and leave this room.
    
    Back out here, go all the way left. Over here, open the Blue Door. In here,
    take the teleporter in front of you. When you teleport, go all the way straight
    and get to the other end of the room, killing any Former Humans in your way.
    Over
    here, head left and go through the opening in front of you. In here, follow
    this hallway until you get to an opening. Now, kill the Former Commando on
    the platform in front of you.
    
    When it's dead, get in center with the opening, and *run* straight to get on
    the platform he was on. On this platform, hit the switch. Now turn back around,
    get in center with the opening again, and *run* straight to get back through
    the opening. Back in here, go all the way straight until you see an opening
    across from you. Go through it, and in here, step on the exit teleporter.
    
    --------------
    Level 19: NME
    --------------
    
    He he, pronounce the name of this level and you get "Enemy".
    
    When you start the level, take the teleporter in front of you. In here, head
    straight and over here, go all the way left and cross this blood pool, killing
    any Imps in your way. Over here, hit the switch on the wall you're facing. A
    new opening to the left will open, revealing a teleporter. Take the teleporter,
    killing any teleporting enemies in your way.
    
    When you teleport, drop down to the floor below you, and go through the opening
    to your left. In here, go through the opening to your right, and in this thin
    hallway, *run* to the opening across from you (watch out for the walls
    lowering, revealing Imps. In here, get the Yellow Key in the center of the
    room. Now turn around and leave this room before you're caught in a major
    Arch-Vile/Revenant (or other enemies) teleporting jam.
    
    Back in this hallway, Get to the end of it and go through the opening, killing
    any Imps in your back. Back in this room, kill all the Demons, Former Human
    Sergeants,
    Former Humans, Cacodemons, Pain Elementals, and Revenants in front of you. When
    they are all dead, head up the stairs in the center of the room. Up here, turn
    around and open the door in front of you (it's the Yellow Door).
    
    In here, go straight and take the teleporter in front of you. When you
    teleport, kill the 2 Former Commandos and the Revenant in front of you, and
    take the teleporter at the other end of the room. When you teleport, kill the
    Former Humans, Former Human Sergeants, Imps, and the Arch-Vile in front of you.
    When they are
    all dead, hit the only switch in this room. Now, turn around and take the
    teleporter again. When you teleport, you'll see a new window in front of you,
    revealing a Cyberdemon.
    
    Kill the Cyberdemon (it can only stay where it is). Now, once he's dead, face
    the Yellow Door, and turn left. You'll see a new opening, revealing a
    teleporter. Go through the teleporter. When you teleport, hit the switch to
    your left (you're where the Cyberdemon was). Once you hit the switch, turn
    around and face the window, and go through it. Down here, head through the
    opening to your left.
    
    In here, follow this hall until you get to a door to your right, killing any
    Former Humans or Former Commandos in your way. When you get to the door, open
    it.
    In here, step on the exit teleporter.
    
    ---------------------------
    Level 20: The Death Domain
    ---------------------------
    
    When you start the level, get to the other end of the room, killing any
    Arachnotrons in your way. On this part of the room, hit the switch on the wall.
    Now go through the opening to your left, and head down the stairs. Down here,
    follow this hall to the right until you see an opening to your left, killing
    any Imps in your way. Go through it. In here, hit the switch to your left, and
    the lift to your right will lower. Get on it, and as you're riding, you'll see
    an opening to your left. Go through it.
    
    In here, head straight to get to the switch in front of you, killing the Demons
    in your way. When you get to the switch, hit it. Now turn around and go
    straight until you get to the end of the room you're in. Now look straight. You
    should see an opening below you. Go straight and you should land on the
    platform it's on. Down here, go through the opening in front of you, killing
    the Former Humans, Former Human Sergeants, and the Former Commandos I front of
    you.
    
    Now, go straight, and the walls in front of you will lower, revealing Hell
    Knights and an Arch-Vile. Kill all of them, and in the northwest part of this
    room is a switch. Hit it, and turn around. The door in the hallway has lowered,
    so go through. In here, head up the stairs in front of you. At the top, go
    straight, and the floor in front of you will raise, revealing Heavy Weapon
    Dudes. Kill them all, and go through the door in this room.
    
    In here, go right until you see an opening, killing the Spectres in your way.
    When you see the opening go through it. In here, head up the stairs. At the
    top, go all the way right to the other end of the room, killing the Heavy
    Weapon Dudes and the Arachnotrons in your way. When you get to the other end of
    the room, go through the opening to your right. In here, follow this hall to
    the left until you see an opening to your left, revealing the Yellow Key. Take
    it.
    
    Now, keep going right and the floor you're on will drop. Down here, go straight
    and go through the opening in front of you. In here, turn around, and you'll
    see two openings with Barons of Hell in them. Kill them all (watch out, they
    teleport a lot), and when they are all dead, blow up the barrels in this room
    (you'll need to), and now from where the Barons came out, go through the
    opening to the right. In here, hit the switch. Now go back where the barrels
    where, and you'll see parts of the wall have lowered (the wall was in between
    the barrels).
    
    Now, with the new gap you can go through, *run* straight to get to the pit in
    front of you that has a toxic floor (it isn't poisonous though). If you get to
    the pit (if not, open the Yellow Door in this room, kill the Hell Knights in
    it, and use the stairs to get back to the ledge), kill the Revenants in it, and
    get the Blue Key. Once you get the Blue Key, you will be teleported. Now,
    you'll be teleported to the other pit. In here, kill the Revenants in front of
    you and go straight. You will be teleported.
    
    You'll be standing on a Berserk pack. Now, open the Blue Door to your right. In
    here, head up the stairs. At the top, kill all the Former Commandos in front
    of you. Now, from the top of the stairs, turn around and face the stairs. There
    will be a door to the right of you. Shoot it with your Pistol, Fist, Chainsaw,
    either Shotgun, or Chaingun and it will open, revealing a Megasphere. With the
    Megasphere, turn around, and go through the opening to your right. In here,
    step on the exit teleporter.
    
    Now, before you enter the next level, you get a little story:
    ------------------------------------------------------------
    You've bashed and battered your way into the heart of the Devil-Hive. Time for
    a search-and-destroy mission, aimed at the gatekeeper, who's foul offspring is
    cascading to Earth. Yeah, he's bad. But you know who's worse! Grinning evilly,
    you check your gear, and get ready to give the bastard a little Hell of your
    own making!
    ------------------------------------------------------------
    
    -----------------
    Level 21: Slayer
    -----------------
    
    If you can get around this level, then it's going to be pretty fun. First,
    start the level by turning around. You'll see a Plasma Gun, a Soul Sphere, and a
    Box of Shotgun Shells on that platform. Before getting onto it, get onto the
    pillar below you. On here is a Super Shotgun, so pick it up. Now get onto the
    platform and collect the Soul Sphere, Plasma Gun, and the Box of Shotgun Shells.
    Once you do, face that circular platform in the middle of this area. Next to
    you is a walkway. RUN onto it (if you can't get to it, lower it like a lift).
    On here, there will be an opening next to you.
    
    Facing the opening, turn around. You'll see another opening at the other end of
    this circular platform. Use either path to get to it, killing the Imps and
    Former Human Sergeants on this platform. Once you get to the opening, go
    through it. In
    here, kill the Former Humans, Former Human Sergeants, Imps, and the Former
    Commandos. Once
    they're all dead, get the Combat Armor and hit the switch in this room. Now
    leave
    this room. Back out here, kill the Arachnotrons and the Former Commandos in
    the middle of the room. After that, kill all the Pain Elementals before doing
    anything else. Now go through the opening at the other end of this circular
    platform, killing the remaining Former Humans, Imps, and Former Human Sergeants
    on here.
    
    In here, get the Backpack and the Rocket Launcher in front of you. Now go
    through the opening to your left. In here, there is a teleporter, but don't
    step into it yet. First, hit the switch at the other end of this room, and then
    step through this teleporter. Once you are teleported, you'll see a Megasphere
    on a platform across from you. Get it and then RUN off this platform onto the
    next one. On this platform, kill the Arch-Vile and then get the Red Key. Once
    you have the Red Key, the platform you're on will sink to the lava pit, so RUN
    back onto the circular platform. If you do get stuck, go to the brown bridge
    and lower it. Back on here, kill the new Former Commandos and Mancubi. Once
    they're all dead, get rid of the Hell Knights and then go back through the east
    opening on the circular platform.
    
    In here, kill any Revenants and then get any Boxes of Rockets that you missed.
    Also in this same area is the Red Door, so open the Red Door and it will reveal
    a switch. Hit this switch and the platform guarding the south opening on the
    circular platform will be lowered. RUN to that new opening, doing the "suicide
    run". Get past all Revenants, Hell Knights, Cacodemons, and Arch-Viles that pop
    up. Once you get to the opening, go through it. In here, a Baron of Hell will
    rise from the floor, so kill it quickly before things get worse. Now you can
    step on the exit teleporter.
    
    -----------------------------
    Level 22: Impossible Mission
    -----------------------------
    
    *******************************************************************************
    Note that in this level are green toxic floors in most areas of the map. Don't
    worry, none of these green toxic floors will hurt you when you step on them,
    even without a Radiation Suit.
    *******************************************************************************
    
    When you start the level, walk up to the floor in front of you, and it will
    lower. Down here, collect the Stimpacks and the health bonuses, and go all the
    way right to the opening across from you. Go through it, and head up the
    stairs. Up here, turn around. You'll see an opening to your left. Go through
    it, and follow this hallway to a gap.
    
    When you get to the gap drop down it. Down here, you'll see a row of Heavy
    Weapon Dudes, a row of Barrels, and a Hell Knight in front of you. Don't
    fire your gun and let the Hell Knight try to attack you. Instead, it will hit
    the barrels, and they will blow up, blowing up the Former Commandos as well.
    Collect all of their Chainguns, and kill the Hell Knight. Now go through the
    opening at the other end of the room (don't worry, the floor in here isn't
    poisonous). In here, get the Blue Key, and the floor you're on will lower.
    
    Down here, kill the Former Human Sergeants, get their Shotguns, and get the
    Energy Cells

    in this room, go through the opening and head down the stairs to front of you.
    Back down here, go through the opening to your left. In here, follow the left
    hand wall to an opening. When you see it, go through it. In this small room, go

    In here, follow the right hand wall to a pedestal with a switch on it. When you
    get to the switch, hit it. Now, turn around and follow the left hand wall to an
    opening, killing any Former Commandos, Former Human Sergeants, or Hell Knights
    in your
    way. When you get to the opening, go through it. In here, go through the
    opening to your right. In here, pick up the Rocket Launcher in front of you and
    the floor you're on will lower, revealing an opening. Go through it. In here,
    try to follow this pathway to the Yellow Key.
    
    While you try to get to the Yellow Key, the pathway you're on will lower. Now,
    drop down to the pit to your right. Down here, kill the Revenant in front of
    you and go through the opening to your right. In here, head up the stairs in
    front of you. At the top, go through the opening to your right. In here, follow
    this walkway to a stair. When you get to it, use it to get to the platform just
    above you. Up here, kill the Arachnotron and hit the switch.
    
    Now go back down the stairs, killing any Revenants, Lost Souls, Pain
    Elementals, or Demons in your way. At the bottom go through the opening. Back
    out here, kill the Revenant on the teleporter and take it. When you teleport,
    you'll be in front of the pathway (it's back). Now follow this pathway to the
    Yellow Key, killing the Baron of Hell in your way. When you get to the Yellow
    Key, pick it up.
    
    Now, turn around, and drop down in the same gap again. Back down here, get to
    the teleporter. Before taking it, hit the switch on the pedestal next to it.
    Now, take the teleporter. When you teleport, turn around, and go through the
    opening in front of you. In here, kill the Former Commandos, and wait for the
    floor you're on to rise. Back up here, go through the opening. Back in here
    again, backtrack back to the level's starting room (where the opening leading
    to the Blue Key was).
    
    Back in this room, open the Blue Door across from you. In here, kill the
    Cacodemons in front of you, and go through the opening at the other end of the
    room. In here, follow the right hand wall to another room, killing any Mancubi
    in your way. When you get to the room, kill the Former Commandos to your

    Mancubi in your way.
    
    In here, follow the left hand wall to a switch, killing any Spectres in your
    way. When you get to the switch, hit it, and when you hit it, keep following
    the wall to an opening. When you get to it, go through. In here, go right and
    lower the lift, get on it, and ride it to the top. Up here, kill the Shotgun
    Guys, and hit the switch on the pedestal. Now drop down to the floor below you,
    and leave this room.
    
    Back in the starting room, backtrack to the room just before the Yellow Key
    room. In here, hit the switch on the pedestal, and now go through the
    teleporter to your left. When you teleport, you'll be surrounded by Barons of
    Hell and an Arch-Vile. Kill them all, and when they are all dead, get the Red
    Key on the platform you were on (if you fell off, get back to the teleporter
    and go through). When you have the Red Key, leave this room (use the Blue Door
    to the right).
    
    In here again, open the door across from you (it's the Red Door). In here, head
    up the stairs in the northwest part of the room. At the top, kill the Revenant,
    and hit the switch on the pedestal. Now, leave this room from where you came
    from. Back in here, go through the opening to your left, heading up the stairs.
    Up here, go through the opening in front of you, killing any Former Commandos
    in your way.
    
    On this pathway, follow it to another opening. In here, follow this hallway to
    the exit teleporter, killing any Former Humans or Former Commandos in your way.
    When you get to the exit teleporter, step on it.
    
    --------------------

    -----------------------------
    Level 24: The Final Frontier
    -----------------------------
    
    When you start the level, turn around, and have your back face the switch. Now
    go straight through the fake wall, (yes, you can walk through this wall), and
    you'll get to a secret room. In here, get all the ammo and the Megasphere, and
    now leave this room, and now hit the switch in front of you. When you do, the
    floor you're on will lower. Down here, you'll see two cages with Arch-Viles to
    the left and right of you. Kill both of them, and when they are dead, face the
    big pit in front of you.
    
    You should see a spiral staircase to your left made out of thin platforms.
    Cross the staircase carefully, and when you get to the top, kill the Revenant
    in front of you, get the Plasma Gun, the Box of Rockets, and the Medikits here.
    Now take the teleporter. When you teleport, walk up to the wall in front of

    see. When you get to the opening, go through. In here, kill the Revenant in
    front of you, and get to the other end of the pathway you're on.
    
    Once you get to the other side of this pathway, *run* straight to get to the
    platform in front of you. When you get on the platform, kill all the Pain
    Elementals and Cacodemons around you, then, when they are all gone (and the
    Lost Souls), hit both switches, then kill the Arch-Vile that appears. When it's
    dead, wait for the pathway to finish rising in the southwest part of this
    platform (kill any enemies around you). When it's done rising, cross it to the
    new opening. In here, kill the Revenant in front of you, collect all the health
    and ammo in here, and go through the other opening in this room.
    
    In here, turn around and face the opening. Hit the switch to the left of it,
    then head right and follow the pathway in front of you until you see a switch
    to your left, killing any Former Human Sergeants, Former Commandos, Barons of
    Hell, or

    When you go through the opening, get the Soul Sphere in front of you, and head
    up the stairs. At the top, go through the opening in front of you, and get the
    Blue Key in front of you. Now, drop back down into the pit, and go back in the
    opening in the southwest part of this pit. Back in here, kill the Arch-Vile in
    front of you (and any of the Former Commandos it revived), and hit the switch
    that's in between two Blue Lights. When you hit it, the wall in front of you
    will lower, revealing a teleporter. Take it. When you teleport, step on the
    teleporter you're on again (be quick, there's a Cyberdemon in front of you),
    and when you teleport, you'll be in front of the exit teleporter instead. Step
    on it before the Cyberdemon shoots you off, and you'll exit this level.
    
    ---------------------------------
    Level 25: The Temple of Darkness
    ---------------------------------
    
    When you start the level, follow the left hand wall in front of you until you
    get to a staircase. When you get to the staircase, head up it. At the top, head
    left, and follow the right hand wall until you get to a switch, killing any
    Former Human Sergeants in your way. When you get to the switch, hit it. Now,

    here, walk straight, and you'll see six staircases rise in front of you (3 to
    your left, 3 to your right). Head up the first one to your left.
    
    Up here, there are two alcoves. Go in each of them and follow them to a wall.
    When you walk up to the wall in front of you in both alcoves, the wall will
    lower, revealing a switch. Hit it, go to the other alcove, walk up to the wall
    and it will lower, then hit the switch. Now leave the alcove you're in, and
    head back the stairs (kill the Hell Knights around you too). Back down here,
    head up any staircase in front of you.
    
    At the top, go through either alcove, walk up to the wall in front of you, and
    it will lower, revealing a switch. Hit it. Now, go through the other alcove,
    walk up to the wall, it will lower, revealing another switch. Hit it, then
    leave this alcove, and head back down the stairs. Down here, go through either
    opening in the south part of this room, killing any Hell Knights or Barons of
    Hell in your way. Now, when you go through either opening, follow it to another
    room (both openings lead to the same room).
    
    Now, when you get to the room, hit the switch in it. Now turn around, and go
    through the teleporter in front of you. In here, kill the Revenants in front of
    you, and go through the opening to your right. In here, follow this hall to

    the opening, *run* straight to get in it. In here, follow this hall to another
    opening, killing any Imps in your way.
    
    When you get to the opening, go through it. In here, hit the switch to your
    right and get the Yellow Key to your left. Now, leave this opening, and follow
    this hall back to the opening you took to get in here. Facing the opening,
    *run* straight to get to the spiral staircase in front of you. Now, head right
    back up the spiral staircase. At the top, go through the opening in front of
    you, and face right.
    
    Back in here, go through the new opening to your right. Follow this pathway to
    another room. In here, kill the Imps and the Revenants in front of you, and get
    the Blue Key near the cages with Former Commandos in them (kill them too).
    When you have the Blue Key, get to the two platforms the Revenants were on in
    this room. You'll notice that one of the platforms has blood on it. Get in
    front of the blood, and press the Spacebar, and the platform will lower,
    revealing an Energy Cell Pack.
    
    Get it, and go to the other lowered platform. Over here, get the other Energy
    Cell Pack and hit the switch (if the platform raised again, just lower it).
    When all that's done, cross the pathway again, and head back into the opening.
    Back in here, head up the stairs in front of you. At the top, follow the right
    hand wall into a room with Boxes of Bullets and Shells, and health bonuses.
    Grab all of them. Now, go through the opening in the south part of this room.
    
    In here, take either pathway to your left or right to get to the other end of
    the room, killing any Arachnotrons in your way. When you get to the other end
    of the room, hit the switch over here, and it will open like a door, so go
    through. In here, hit the switch. Now leave this room. Back out here, use
    either pathway again to get to the other end of the room. Over here again, use
    the new pathway to get the Red Key in the center of the room.
    
    When you have the Red Key, face left, and drop down to the pit below you. Down
    here, go through the opening across from you. In here, kill the Revenants, and
    get the Radiation Suit and the Megasphere. Now, leave this small room. Back out
    here, follow the left hand wall to a teleporter, killing any Mancubi in your
    way. Once you get to the teleporter, turn around. You'll see an opening to your
    left and right. Go through both of them, and hit the switch in both openings
    (watch out for the Revenants).
    
    Now, get back to the teleporter, and go through. When you teleport, follow the
    right hand wall to a pair of Red Bars. Press the Spacebar on them, and they
    will open like a door. Now go through into the room. In here, hit the switch on
    the pedestal. Now leave this room. Back out here, you'll see that stairs have
    raised to the platform in the center of the room. Use these stairs to get to
    the platform, and on here, take the exit teleporter.

    staircase. When you get to it, head up it. At the top, go through the opening
    to your right. In here, turn right, then head down to the pit below you. Down
    here, go all the way straight, and follow this hall until you see an opening to
    your left.
    
    When you see the opening, go through it. In here, walk up to the wall in front
    of you, and it will lower like a lift. Get on it, and ride it to the top. Up
    here, go right to the wall in front of you and it will lower, revealing an
    opening, so go through. In here, get to the other end of the room. Over here,
    hit the switch on the wall. Now, drop down to the pit to your right. Down here,
    go through the opening to your left.
    
    In here, follow the right hand wall to a staircase. When you get to it, head up
    it. Up here, follow the right hand wall back into the room with the Megasphere.
    Back in this room, go back through the same opening in the west part of this
    room. In here again, go left, and head up the stairs in front of you again. At
    the top, go through the opening to your right. In here, *run* all the way
    straight to get to the platform in front of you.
    
    When you get on the platform, you should be near/around the exit teleporter,
    and you should see two openings leading to it (one north of the teleporter and
    one south of the teleporter, which is blocked off by Blue Bars). So go through
    the north opening to get to the exit teleporter, then step on it.

    Level 27: Anti-Christ
    ----------------------
    
    When you start the level, go straight, and get the Soul Sphere in front of you.
    Now, there will be a new opening in front of you, to the left, and to the
    right. Go through the new opening to your left, killing any Pain Elementals or
    Hell Knights in your way. In here, follow this hall to an opening. When you get
    to the opening, you should see another platform with a teleporter in front of
    you. *Run* straight to get to the platform, and kill the Former Commando on

    Once you get on the platform, step on the teleporter. When you teleport, kill
    the Former Commandos in front of you, hit the switch, get the ammo and health

    Elementals in your way. When you go in the opening, follow the left hand wall
    to a pathway.

    and now use the pathway to get back to the other room. Back in here, go through
    the opening in front of you. In here, get the Backpack, and the wall in front
    of you will lower, revealing a teleporter. Take it. When you teleport, follow
    the pathway to your left to the Yellow Door. When you get to the Yellow Door,
    open it.
    
    In here, follow the right hand wall to a Berserk. Get it, and get on the
    platform to the left of it. Now, you should see a platform with a Revenant on
    it. Kill it, and *run* to get to the platform it was on. On here, take the
    teleporter. When you teleport, turn right, and you should see a platform with a
    switch just below it. Drop down to the platform, and hit the switch.
    Now, take the teleporter to your left. When you teleport, go straight to the
    other end of the room. Over here, take the teleporter. When you teleport, kill
    the Revenant in front of you, and now get the Blue Key in front of you. Now, go
    back through the teleporter before loads of monsters get teleported into this
    room. When you teleport, get onto the pathway to your left. On the pathway,
    follow the right hand wall to an opening, killing any Barons of Hell in your
    way.
    
    When you get into the opening, get in front of the opening at the other end of
    this room. Now, wait for a pathway in front of you to finish rising. When it's
    done, cross this pathway to another platform. On here, kill/avoid the Spider
    Mastermind in front of you, and hit the switch on this platform. When you hit
    the switch, the Blue Bars behind the switch will open, revealing a Berserk and
    the exit teleporter. Get the Berserk, and step on the exit teleporter.
    
    ---------------------
    Level 28: The Sewers
    ---------------------
    
    When you start the level, open the door to your left. In here, grab a Computer
    Area Map. Now, with the back against the door you just came from, turn right.
    See those computers on the wall? Shoot them, and they will open, revealing Lost
    Souls. Kill them and turn around, facing the wall across the computers. You'll
    notice another secret door has opened, revealing a Soul Sphere. Grab it, and
    then head right and get to the middle of the room, and turn right. You should
    see part of a floor in between two torches.
    
    Step on the floor between two torches, and it will lower. Down here, hit the
    switch in this room, and the wall to your right will lower, revealing a new
    opening. Before going through it, turn left. See that black "flag" on the wall?
    Press the Spacebar on it and it will open, so go through. In here, grab all the
    Super Shotguns and Plasma Guns then leave this room. Back in here, go through
    the opening in front of you. In here, turn left. See those books? Press the
    Spacebar on them and they should open, so go through. In here, kill the
    Mancubus, and then grab the Backpack, all the Energy Cell Packs, the Combat
    Armor,
    and the Chaingun. Now leave this place. Back in here, hit the switch to the
    left.
    
    When you hit the switch, walls in front of you will lower, revealing new
    openings. Go through any of the new openings. In here, hit the switch in the
    opening across from you. When you hit the switch, walls to the left and right
    of you will lower, revealing Revenants, Barons of Hell, and Hell Knights. Kill
    them all, then get the Yellow Key in the south part of this room. Now, go
    through the opening where the Hell Knights, Revenants, and Barons of Hell came
    out of.
    
    In here, hit the switch, and the wall in front of you will lower, revealing an
    Arch-Vile, and another opening. Kill the Arch-Vile, and go through. In here,
    hit the switch, and leave this room. Back in here, hit the new switch in the
    middle of this room, and walls in front of you will lower, revealing openings.
    Go through either one. In here, kill the Revenants in the corners of this room.
    When they are dead, press the Spacebar on the walls in the south part of this
    room, and the wall should open, revealing a new room. Go through.
    
    In here, kill the Mancubus in front of you, and collect the ammo and the armor
    in here. Now leave this room. Back in here, go through the opening in the east
    part of this room. In here, lower the lift in the northeast part of the room,
    get on it, and ride it to the top. Back up here, follow the right hand wall to
    an opening. When you get to the opening go through. In here, cross the
    platforms in front of you to get to two switches, killing the Heavy Weapon
    Dudes in front of you.
    
    When you get to the two switches, hit them. Now, drop down to the floor below
    you. Down here, Go through either opening to the left or right of the opening
    in the middle, then follow the hall you're in to another room. In here, open

    part of this room, killing any Mancubi in your way.
    
    In here, follow the right hand wall until you get to a room that has a glowing
    wall in it. Walk through the glowing wall, and you'll be teleported. When you
    teleport, go all the way straight into the opening across from you. In here,

    ----------------------------
    Level 29: Odyssey of Noises
    ----------------------------
    
    You start the level standing on a Backpack. Get all the ammo and health here,
    and open the door in this room, and go through. Out here, you'll see that this
    level is made up of streets and buildings (I call this level The Streets of
    Romero). From where you are, go left until you see a new street to your left.
    Take it. Over here, keep going straight until you get to the pit in front of
    you (watch out for the Cyberdemon's rockets).
    
    When you get to the pit, turn right, and you should see a passage. Go through
    it. Now, follow the small fence/wall to your left until you get to a door. When
    you get to the door, open it, and go through. In here, head up the stairs to

    Now, follow the left hand wall to a door. When you get to the door, open it.
    Now, get the Red Key in front of you, and leave this small room. Back in here,
    kill the new Arch-Vile, and go in the opening it came out of, and hit the
    switch. Now turn around, and open the door to your left, and leave this room.
    Back out here, head down the stairs in front of you to get back down to the
    platform. Back down here, head down the stairs to your left.
    
    Down here, again, open the door to your right, and go through. Out here, go
    back through the small passage to your right, and follow it to a street. When
    you get to the street, go all the way left until you see a street to your right
    and left. Take the street to your right until you see another street to your
    left. Go to that street. Now, from where you are, go straight until you see an
    opening to your right. Go in it.
    
    In here, go straight until you see another opening to your right. When you see
    it, go in it. In here, head up the stairs. At the top, follow the right hand
    wall to an opening, killing any Former Commandos in your way. When you get to
    the opening go in it. In here, *run* straight to get to the platform across
    from you. In here, get to the opening across from you, and *run* through it to
    get to another platform.
    
    On here, get the Yellow Key in the northwest part of this platform. Now, drop
    down to the street below you. Down here, go through the opening across from
    you. In here, go all the way straight until you get to a wall. When you get to
    the wall across from you, turn left. Now, follow this right hand wall until you
    get to a street. When you get to the street, go straight, and open the Yellow
    Door across from you, and go through.
    
    In here, hit the switch in front of you, and leave this room (watch out for the
    Revenants). Back out here, get back on the street, and go all the way right
    until you get to a 4-way intersection. When you get to it, take the street to
    the left, and keep going left until you see another street to your right. Take
    the street to your right. Now, go all the way straight until you see a door to
    your left (skip the one just on the edge of the street, not the one near the
    pit).
    
    When you see another door to your left, open it. In here, get the Blue Key, and
    leave this room. Back out here, get back on the street, and go all the way
    right until you see a street to your right and left. Take the street to your
    right, and keep going straight until you see another street to your left. Take
    that street. Over here, keep going straight until you see an opening (in a
    building) to your left. When you see the opening, go through it.
    
    In here, head up the stairs in front of you. At the top, kill the Revenants and
    the Imps in front of you. Now, get in center with the platform in front of you,
    and *run* straight over the gap to get to the platform. Now, turn left, and
    *run* to get to the next platform across from you. Keep running across these
    platforms until you get to the Blue Door, killing any Imps or Revenants in your
    way.
    
    When you get to the Blue Door, open it. In here, hit both switches in this
    room, and leave. Back out here, turn left, and jump off this platform. Down
    here, go all the way left until you see another street to your left. When you
    get to it, go on that street. Now, go all the way straight until you bump into
    the wall way across from you. When you run into the wall, turn around, facing
    straight.
    
    See that brown building to your right? There is an opening in it. Go through
    the opening, and head up the stairs. At the top, turn right. Cross the
    platforms in front of you to get to the exit teleporter.
    
    ------------------------------
    Level 30: The Gateway of Hell
    ------------------------------
    
    Congratulations, you've made it to the final level of Plutonia! Now, collect
    ALL the ammo, weapons, and the Megasphere in this room. Now, go through the
    opening in here, and drop down to the floor below you. Down here, turn right.
    See that opening? Walk through it, and you'll be teleported. When you teleport,
    the floor you're on will raise. When it's finished raising, go through the
    opening across from you (watch out for the Arch-Viles). In here, walk forward,
    and the wall in front of you will lower, revealing another opening (kill the
    Former Commandos in the cages).
    
    When the wall's done lowering, go through the new opening. In here, drop down
    in the small pit in the center of the room (not the lava pit). In this pit,
    kill the Cyberdemon on the platform (you'll need to in order to kill the final
    boss). When the Cyberdemon's dead, you'll notice a pillar and two switches in
    this pit. Hit the switch on the east part of the switch first. The pillar will
    rise just a little.
    
    Now, hit the other switch, the pillar will lower. Get on it. Now, the final
    boss is the huge demon head on the wall, so when you get on the pillar, face
    the wall where the final boss is. Pull out your Rocket Launcher (it's the only
    weapon that can defeat the final boss). Also, the final boss will shoot skull
    boxes from his brain, and it will turn into a monster (it won't be a Former
    Human,
    Former Human Sergeant, Former Commando, Lost Soul, Spider Mastermind, or a
    Cyberdemon)
    Now, wait for the pillar to rise. Once it rises and you can see the final boss,
    time your Rockets just right so they will go through the green hole where his
    brain is.
    
    If the Rocket goes through the brain, you'll hear a loud scream. Even if you
    miss, hit the switch to lower the pillar, and try again. Now, it should take 3
    hits to kill the final boss (the wall will explode if you kill him). Or, it can
    take 2 hits to kill it. Anyway, keep firing rockets through his brain until he
    dies. Once you defeat him, congratulations!
    
    Now, you get a little story:
    ------------------------------------------------------------
    The Gatekeeper's face is splattered all over the place. As its tattered corpse
    collapses an inverted gate forms and sucks down the shards of the last
    prototype accelerator, not to mention the few remaining demons. You're done.
    Hell has gone back to pounding bad dead folks instead of good live ones.
    Remember to tell your grandkids to put a Rocket Launcher in your coffin. If you
    go to Hell when you die, you'll need it for some final cleaning-up...
    ------------------------------------------------------------
    After the story, the cast of enemies comes up, showing their movements, sounds,
    and all that. Press a key to scroll through each enemy.

    -----------------------
    
    Number of Secrets: 19
    
    Holy crap, 19 secrets! They're still pretty easy. Here I go.
    
    1. Starting the level, step through the teleporter in front of you. In here,
    hit the switch in front of you and the floor you're on will lower. Down here,
    turn right and you will see a Super Shotgun. Collect it and turn right to the
    bars. If you notice, there is a solid wall with designs on it to the left of
    the bars. This is a hidden door, so open it and make sure you go through it for
    a secret.
    
    2. From secret 1, hit the switch in secret 1. Now turn right and you will see a
    new opening across from you, so go through it. In here, make sure to kill the
    Former Commando and the Revenants. Now walk forward and you will get credit
    for a secret.
    
    3 through 8. Here are easy secrets right here. From secret 2, turn left and you
    will see a staircase leading up to a Megasphere. Each step you step on to the
    Megasphere counts as a secret. By the time you get up to the Megasphere, you
    should have 8 secrets. Getting the Megasphere at the top does not count as
    getting a secret, however.
    
    9. Now head back down the stairs and leave this room. Back out here, go all the
    way straight to the Rocket Launcher. Now where the Combat Armor is, we'll call
    this the "central walkway" for now because a lot of the secrets are around this
    area. Once you have the Rocket Launcher, face the pit and turn left. You'll see
    a teleporter in the pit, so step through it. In here, walk forward towards the
    Plasma Gun, Soul Sphere, and Backpack to get credit for a secret.
    
    10. We're not done here yet. With your back on the teleporter (don't step into
    it), turn right and you'll see designs on a wall. This is a hidden door, so
    open it and go through it. In here, walk forward and get the BFG, and then
    you'll get credit for a secret.
    
    11. Go back to where the Plasma Gun and save your game. Now in this area is a
    window. Turn left to face the window. Across from you is a pillar with a
    Medikit on it. Back up and RUN and try to land on it (if not, load up your
    saved game). Once you land on the pillar, you will get credit for a secret.
    Also landing on this pillar will open the door to secret 12.
    
    12. From secret 11, drop down to the floor below you. Down here, turn left and
    you'll see an opening with an Invincibility Sphere in it. Collect it and you
    will get credit for a secret.
    
    13. From secret 12, go back to the pit and step through the teleporter. Now
    you'll be taken back to the central walkway. Now turn left and you will be
    facing where the Rocket Launcher was. Facing this pit, drop back down to it.
    Down here, step through the same teleporter to your left. Back in here, turn
    around and you'll be facing a wall. This is a hidden door, so open it and go
    through it. In this secret area, there are plenty of health potions for you to
    grab.
    
    14. From secret 13, follow this hallway to a teleporter. Once you get to the
    teleporter, step through it and you'll be taken to the central walkway again.
    This time, turn around and you'll see a staircase in front of you. Now if you
    notice, there is a slight opening you can go through to the left of the
    staircase, so go through it and you'll drop down to a pit. Down here, step
    through the teleporter and you'll get credit for a secret once you are
    teleported.
    
    15. From secret 14, walk forward towards the rockets and you'll get credit for
    a secret. Collect all of the health and ammo here while you're at it before you
    leave this place.
    
    16. Now, if you'll notice, you'll see a Rocket in front of a wall. This is a
    hidden door, so open it and go through it. In here, walk towards the teleporter
    and you'll get credit for a secret. Now step on the teleporter. On this
    platform, get the Box of Rockets and the Medikit.
    
    17. From secret 16, open the door to your left and it will lower, revealing a
    teleporter, a Box of Shotgun Shells, and an Invisibility Sphere. Step through
    to get credit for your secret.
    
    18. From secret 17, step through the teleporter and progress the game until you
    have the Yellow Key. Once you have the Yellow Key, go back to the central
    walkway again. Now, pretend the Rocket Launcher you got earlier is still to
    your right, and now you'll be facing a staircase, so head up it. At the top,
    you'll see an opening to your right, so go through it. Get the Energy Cell
    Packs in this secret area.
    
    19. Now, from secret 18, leave the secret room and turn left. You'll see a
    switch on a pedestal across from you, so walk up to it. Facing this switch,
    turn around and save your game. You will see a lava waterfall to your left. RUN
    onto it. If you can't get to it, save your game. On here, you'll see an opening
    to your left, so go through it. In this secret area, get the Soul Sphere.

    Suit, go through the opening to your right. In here, go all the way straight
    and you will stop at a wall. Once you stop at a wall, turn right and you'll see
    a wall to the left of the opening. This is a fake wall, so go through it. In
    this secret area, collect all of the health potions.
    
    2. From secret 1, progress the game until you get to the Red Key. Once you have
    the Red Key, a wall to your left will open, revealing enemies. Kill them at

    is a hidden door, so open it and go through it. In here, get the Radiation Suit
    and then you'll get credit for a secret. Now if you want, step through the

    ledge. Back up and RUN through the window to get on this ledge. On here, turn
    left and you will see another window with a BFG and a Megasphere in it. Save
    your game again. Now face the window at an angle, and RUN in that direction to

    this area for a secret door. Once you find it, go through it. In here, you will
    get credit for a secret. Also collect the Rockets and the Backpack while you
    are in here too.
    
    4. While you are in this secret area, step on the teleporter in here. Instead
    of you being teleporter, a pillar in this room will lower, revealing a
    Megasphere. Step on the pillar and collect the Megasphere for your credit for a
    secret.
    
    5. From here, progress the level until you get to the room with the Red Key.
    Once you get to the room with the Red Key, drop down to the pit where the Red
    Key is. Down here, get the Red Key and then look for an opening at the other
    end of the room. Once you see it, go through it. In here, turn left and you
    will see a platform, so get on it. On here, hit the switch and the lift in
    front of you will lower, so get on it and ride it to the top. Up here, get the
    Soul Sphere to get credit for a secret.
    
    -----------------------------
    Level 24: The Final Frontier
    -----------------------------
    
    Number of Secrets: 7
    
    1. Once you start the level, turn around and you will be facing a wall. This is
    a fake wall, so walk through it. In this early, secret, get the Megasphere,
    Backpack, Box of Shotgun Shells, and the Box of Rockets.
    
    2. Now go back and hit the switch, and then the floor you're on will lower.
    Down here, you will see pillars forming a staircase leading to a higher
    platform, and each pillar has a health potion on it. Now get on the FIRST
    pillar and then turn left. Save your game and then RUN off of this pillar, and
    then you should land into a little pit. If not, load your saved game and try
    again. In this pit, there is a Soul Sphere, Invisibility Sphere, and an Energy
    Cell Pack. Once you fall in here, you'll get credit for a secret.
    
    3. While you are in secret 2, collect the goodies and then step through the
    teleporter. Once you are teleported, head up the pillars forming staircases to
    get to a higher platform. At the top, step through the teleporter to your
    right. In here, walk forward and the door in front of you will open, so go
    through it. In here, follow this hallway to a walkway. Once you get to the
    walkway, cross it to a platform. On here, hit both switches on both pillars,
    and then a walkway will be rising to an opening. Cross it and go through it. In
    here, turn left and go through the opening. Now hit the switch next to you and
    go down into the pit.
    
    Down here, look for a small pit with a switch inside (there is a Radiation Suit
    next to it and a green arrow on the floor pointing to it). Go into the pit and
    hit the switch. Now turn around and the lift behind you will lower, revealing
    an opening, so go through it. In this secret area is a Soul Sphere, Boxes of
    Rockets, and an Energy Cell Pack.
    
    4. While you are in secret 3, look for a wall with black spots on it. This is a
    hidden door, so open it and go through it. In here, step through the
    teleporter, and you'll be taken to a secret room. In this secret room is a
    Soul Sphere, a Combat Armor, two Backpacks, a Radiation Suit, and plenty of
    Boxes
    of Rockets. Step into this room to get credit for a secret. Also get all of the
    goodies here, as you'll really need them.
    
    5. From secret 4, turn back around and step back through the teleporter. You'll
    be taken to the platform at the start of the long walkway. Once you are
    teleported, you'll get credit for a secret, but you get no goodies in return.
    This sucks.
    
    6. Now progress the game until you have the Blue Key. Once you have the Blue
    Key, backtrack back to the small room where the Blue Door is. In here, face the
    Blue Door and turn around. You'll see a new opening, so go through the opening
    and you will get credit for a secret. In this secret room are two Medikits and
    a Box of Shotgun Shells.
    
    7. Now go back into the pit from secret 6. Down here, look for any teleporter
    you can find in the pit. Once you find a teleporter, step through it and you'll
    be taken back out of the pit in front of the long walkway again. From here,
    follow the long walkway until you see an opening to the left. Inside the
    opening are red walls surrounding it. Go through this opening. In here, search
    for another opening that has Energy Cells in it. Walk into this opening to get
    credit for a secret.
    
    ---------------------------------
    Level 25: The Temple of Darkness
    ---------------------------------
    
    Number of Secrets: 1
    
    1. From the start of the level, progress the level all the way until you get to
    the area with the Blue Key. Once you get to the Blue Key, pick it up. Now turn
    around. You will see a platform with an Energy Cell Packs on both platforms.
    Now if you notice, there is blood on one of the platforms. Get in front of the
    blood and press Spacebar on it. Both platforms will lower. Turn around and you
    will see a switch. Hit it before both platforms rise again, otherwise lower
    them again. Once you hit the switch, cross the walkway and head up the stairs.
    Back up here, turn right and you'll see a new opening to your right. Go in it
    for a secret. In here are health potions and spiritual armor, as well as Boxes
    of Bullets and Shells.
    
    -----------------
    Level 26: Bunker
    -----------------
    
    Number of Secrets: 4
    
    Note in this level that there is an error. This error causes you to only get
    75% secrets at maximum, because one of the secrets was put right on a
    teleporter. That meant you could not step on the teleporter and get credit for
    a secret before being teleported, so you can only get up to 3 secrets. This
    secret is the one that takes you to a Megasphere. If you were to use IDCLIP to
    walk right over the teleporter, you would get credit for a secret. But no
    cheating. I will still take you to it.
    
    1. From the start of the level, head down the stairs in front of you. Down
    here, turn right and head straight. Now fall into the river below you. Down
    here, turn right and follow this long river until you get to an area with a lot
    of pillars in them. Once you get to this area, look for blood on a pillar. Once
    you find it, press Spacebar on it and the pillar will open, revealing a
    teleporter. Step through it and you'll be taken to a Megasphere (this was
    supposed to be a secret but there was an error).
    
    From here, turn around and you'll see a staircase, so head down it. Down here,
    head up the stairs to your left. At the top, walk straight and you will stop at
    a wall. Now turn left and you'll see a mix of green and gray on the walls. This
    is a hidden door, so open it and it will reveal a teleporter, so step through
    it. In this secret area is a Combat Armor, Medikits, and Boxes of Shotgun
    Shells.
    
    2. From secret 1, step back through the teleporter. Back in here, open the
    hidden door. Back in this area, turn around and you'll see an opening across
    from you, so go through it. In here, turn left and follow this path to an
    Energy Cell Pack. Once you get to it, notice there is another gray and green
    design on the wall to your left. This is a hidden door, so open it and it will
    reveal 4 Energy Cells. Walk through for a secret.
    
    3. From here, go back to the opening we used to enter this room. Back out here,
    go all the way straight to the windows across from you. Use the windows to
    enter the river below you. Back down here, turn right and follow this river
    until the walls around you change from green to brown. Once you see brown walls
    around you, you'll notice a Combat Armor on a high platform to your right. To
    get this, notice on the ceiling. You'll see bars hanging from the ceiling. Head
    left and you'll see more bars from the ceiling. Get under the bars and then
    turn right.
    
    On this wall, press Spacebar on it and it should lower. This lowers the
    platform with the Combat Armor, so RUN to it and get it, and then you'll get
    credit for a secret. Otherwise, go back and lower the same wall again.
    
    ----------------------
    Level 27: Anti-Christ
    ----------------------
    
    Number of Secrets: 3
    
    1. Once you start this level, save your game because this secret is a little
    hard to pull off. Now turn left and you'll see a huge pit below you. Slowly
    walk off this platform and you should land onto a small one below you. Down
    here, if you landed on a platform, you'll get credit for a secret. On this
    platform is a Backpack, a Combat Armor, an Invincibility Sphere, and a BFG.
    Collect all of them on this secret area.
    
    2. From secret 1, step through the teleporter next to you and you'll be back at
    the level's starting point. From here, progress the game until you have the
    Yellow Key. Once you have the Yellow Key, turn around and cross the walkway
    back to the opening. Back in here, get to the lift across from you. Now walk up
    to it and then it will lower, revealing a teleporter, so step through it. From
    here, turn around and you will see a lift with a Combat Armor at the top. Lower
    the lift, get on it, and ride it to the top. Up here, walk forward to get
    credit for a secret.
    
    3. While you are still on secret 2, you will see a Rocket in front of a wall.
    This wall also has black spots on it. This is a hidden door, so open it. Now
    save your game and drop down to the floor right below you. Down here, turn left
    and you will see a Soul Sphere on a pillar. Walk up to the pillar and get the
    Soul Sphere for credit for a secret.
    
    ---------------------
    Level 28: The Sewers
    ---------------------
    
    Number of Secrets: 4
    
    1. Once you start this level, head down the stairs in front of you. At the
    bottom, turn left and face the wall. You will see black scratches on the wall.
    This is a fake wall, so walk through it. In here, head up the stairs to the
    left. At the top, walk up to the Boxes of Rockets and you will get credit for a
    secret. You will also get an Invisibility Sphere as you are heading up the
    stairs.
    
    2. Now go back to the level's starting area. Back over here, open the door near
    the starting teleporter and go through it. In this room, walk forward and you
    will notice computer designs on the wall to your right. Shoot this wall with a
    Pistol, either Shotgun, a Chaingun, or use a Fist or Chainsaw on it. It will
    open, but a wall behind you will also open, revealing a Soul Sphere. Get the
    Soul Sphere to get credit for a secret.
    
    3. From secret 2, turn right and you will see a long hall. Now walk forward and
    you will see a floor in between two torches. This is a lift, so walk on that
    floor and it will lower. Down here, hit the switch to lower the wall next to
    you, and then go through it. In here, walk forward into this room and you will
    see a bookshelf to your left. Walk up to it and pres Spacebar and then it will
    open, so go through it. In this secret area is a Chainsaw, Chaingun, Combat
    Armor, and Energy Cell Packs.
    
    4. Once you have the Yellow Key, go back to the lift we used to get down here.
    Now lower it, get on it, and ride it to the top. Up here, go through the
    opening in front of you. In here, use the small platforms in the slime pit to
    get to the switches across from you. Once you get to the switches, turn right.
    Now cross this thin ledge and you will get to a small platform with slime on
    it. Get on this platform and then face the wall. This is a fake wall, so walk
    through it. In this secret area are a few Boxes of Rockets.
    
    ----------------------------
    Level 29: Odyssey of Noises
    ----------------------------
    
    Number of Secrets: 2
    
    1. Once you start this level, progress the level until you get the Red Key.
    Once you have the Red Key, a wall near you will open, revealing a switch. Hit
    the switch and then leave this room. Back out here, go back to where you
    started the level. Facing the door, turn left and follow this right hand wall
    to a new opening. Once you get to it, go through it. In this secret area,
    collect the Energy Cell Packs.
    
    2. From secret 1, progress the game until you have the Yellow Key. Once you
    have the Yellow Key, a wall to your right will open. This is tricky to pull
    off. Save your game and then back up and RUN to get into the new opening to the
    right of where the Yellow Key was. In here, get the Megasphere and now you will
    have credit for a secret.
    
    ------------------------------
    Level 30: The Gateway of Hell
    ------------------------------
    
    Number of Secrets: 0
    
    In the last level of Plutonia, there are no secrets. All the ammo you need is
    at the beginning and the end of the level to destroy the final boss. Even
    though there are no secrets in this level, you may finish the level with 100%
    secrets in some source ports like ZDoom. Good luck finishing off the final
    boss!
    
    -------------------
    Level 31: Cyberden
    -------------------
    
    Number of Secrets: 1
    
    1. As you know, you need to free 4 Cyberdemons to progress into the level. Once
    you start this level, progress it until you free the 4th Cyberdemon. Once you
    free the 4th Cyberdemon, go to its open cage. Hit both switches to open both
    doors, and then go through it. In here, head up either staircase in front of
    you. At the top, go through the opening in front of you. In here, turn left and
    follow this path to a switch. Once you get to a switch, hit it. Now leave this
    area and head back down the stairs. Down here, go through the new opening to
    your right. In here, turn right and you'll see a face icon on the wall. This is
    a hidden door, so open it and it will reveal a teleporter, so step through it.
    In here, you'll get credit for a secret. Also you'll get a Box of Shotgun
    Shells and a Box of Rockets.
    
    ------------------
    Level 32: Go 2 It
    ------------------
    
    Number of Secrets: 2
    
    1. Once you start this level, go through the opening to your right. In here,
    turn left. Now you notice that this part of the level is a replica to Level 1:
    Entryway of Doom II. From here, turn around and you'll see a staircase, so head
    up it. At the top, drop down to the big area to the left. Down here, you'll get
    credit for a secret. If you think of Map 1 from Doom II, this is the big secret
    area where you would get the Shotgun in Doom II.
    
    2. Once you have the Yellow Key, get to the Yellow Door. Once you get to it,
    open it and go through it. In here, walk up to the Red Key and you will get
    credit for a secret. In Map 1 of Doom II, this is where the hidden Rocket
    Launcher was. This time it is a nice Cyberdemon, Boxes of Rockets, and a Red
    Key. Seems like a better deal for me.

    20.) The Plutonia Experiment Bugs and Errors
    ----------------------------------------
    This section shows all known bugs and errors I've found. Email me if I miss
    any!
    
    1. In Level 26: Bunker (Plutonia), there is a maximum secrets score of 75%.
    This is because when you are in the room with the pillars, one of them has a
    secret teleporter leading to the Megasphere. The secret credit was put right on
    the middle of the teleporter, so you cannot get credit for the secret before
    being teleported to the Megasphere without cheating. If you want credit for
    this secret, enter IDCLIP to walk through the teleporter without being
    teleported. You will get credit for a secret, and then press IDCLIP to turn it
    off.
    
    2. In Level 28: The Sewers (Plutonia), you cannot get a 100% items score
    because in the "4 way intersection hall" there are 2 Automaps. You can only
    pick up one of them (doesn't matter which), and not the other. Automaps also
    count towards your item score.
