    	      Doom Solution by AMC (alexmcgregor20@hotmail.com)
    Version 2.5 Written on 11/3/02 
    This is the full solution to both the Original and Ultimate Doom(TM).
    The secrets aren't listed and neither are the monsters. This is just
    a step-by-step walkthrough to help you finish each level. I decided
    to do this after reading George Foot's great Doom 2 solution. If you wish
    to put this walkthrough on your website, please contact me first.
    Version Changes
    Version 1 3/3/02= Original version, only contained the original doom 
    Version 2 8/3/02= Added solution for episode 4 and weapons and 
    fighting advice sections.
    Version 2.5 11/3/02= Fixed some typos and added the beginning
    of the rating system.

    Weapon Advice
    1. Fist
    Your marines fist is the weakest weapon in the game and should only be
    used in conjunction with a berserk pack, when you have no-ammo or when 
    ammo conservation is important. The fist works best against weak enemies 
    such as former humans and enemies that have to get close to attack
    (excluding Lost souls as they are too fast).
    Best Vs: Former humans, Demons, Specters
    Weak Vs: All other monsters
    2. Chainsaw
    The chainsaw is a decent close range weapon but like the fist, it's only
    useful in low ammo situations. When using on demons, try to back up
    while doing it or you may get bitten.
    Best Vs: Former human, Former Human Sergeants, Demons, Specters,
    Cacodemons, Lost souls
    Bad Vs: The rest.
    3. Pistol
    The pistol is a rather weak weapon but due to its range, it's more useful
    then the fist. Still, you should use it only when your last resort is the 
    Once you have the chaingun this weapon becomes totally useless.
    Best Vs: Human enemies
    Weak Vs: Everything else
    4. Shotgun
    The shotgun is the best all around weapon as it is rather powerful, and
    ammo for it is plentiful. The one problem is that it has a slow reload
    rate so it's not good verses whole hoards of demons that are attacking
    from every direction.
    Best Vs: Human enemies, imps, lost souls
    Worst Vs: Cyberdemons, Spider Mastermind
    5. Chaingun
    The chaingun basically is a rapid firing machine gun that uses the same
    ammo as the pistol. However, the chaingun is MUCH better than the
    pistol and is useful for killing large amounts of enemies, although it takes
    a while to kill the enemies.
    Best Vs: Human enemies, imps, cacodemons
    Worst Vs: Cyberdemon, Spider Mastermind
    6. Rocket launcher
    The rocket launcher is the second most powerful weapon in the game.
    But you must be careful with it as the splash damage it causes as it can
    easily kill your marine. However this splash damage does lots of damage
    to the enemies so it evens out.
    Best Vs: All enemies
    Worst Vs: None
    7. Plasma Rifle
    The plasma rifle is a rapid firing weapon that does more damage then
    the chaingun. Be warned that some enemies seem to be able to resist
    the damage from this gun, and at times the projectiles can clog up the
    Best Vs: All enemies except Cyberdemons and Spider Masterminds.
    Worst Vs: Cyberdemons & Spider Masterminds
    8. BFG9000
    The best weapon in both this game and probably any game I've ever played!
    Although it takes a while to charge and takes a lot of ammo, the damage
    dealt is massive. Best used against tough enemies.
    Best Vs: All enemies
    Worst Vs: Nothing, BWHAHAHAHA!
    Fighting advice
    Learn to strafe. I cannot stress this enough. Strafing is the most useful
    ability in not only Doom but many other first person shooter games.
    Know when to fight and when to run, if you have 2 bullets and are being
    attacked by a Baron of Hell, you should try to escape and gather some
    ammo. Then you can return to finish him off (heh, heh, heh)
    Try to sneak around and avoid fights. Monsters usually hear you when you
    fire off shots, so only shoot if necessary and keep as far away from monsters
    as possible. Avoiding conflicts is probably the only way to survive on
    Nightmare mode.
    Former Humans: Use either the pistol or a close range weapon to take them
    out. No need to waste ammo.
    Former Human Sergeants: The sergeants are VERY annoying as they do a
    fair bit of damage with their shots. Try to take them out quickly with a
    shotgun, or a pistol if that's all you have.
    Imps: Are the most common enemy in Doom, so get used to them. You
    can tell if there are any imps by listening to what I call the clicking sound.
    Anyway, the shotgun is the best weapon to kill them with. Usually you will
    have a shotgun by the time you first meet them, so fill 'em with lead and
    keep moving.
    Demons: Pig like creatures that do a reasonable amount of damage, have
    a fair amount of health but must get close to attack. Best weapons to use
    are the chainsaw and probably the shotgun (if they are in small groups).
    The demons usually travel in small groups of 3 to 6, so weaken them
    with the shotgun then finish them off with the chainsaw, or even your
    bare fists.
    Specters: Exactly like the demons except they are invisible. Be
    especially careful in dark areas, where the Doom designers seem to
    like putting them.
    Lost souls: Flaming skulls that try to ram you. They usually travel alone
    or in large groups of 10 or more (on Ultra-Violence). Try to take them
    out quickly with either the shotgun or chaingun.
    Cacodemon: Huge flying 'balls' that shoot lightning balls, they are fairly
    common and can be easily killed by a chaingun, plasma rifle or chainsaw,
    although it does take a while.
    Barons of hell: Big goat-like demons, they deal lots of damage and can take
    lots of damage too. Try not to get too close to them as their scratch 
    (punch?) attack is much more powerful then their slimeball attack. Use a
    powerful weapon such as the rocket launcher or plasma rifle to take these
    guys out quickly.
    Spider Masterminds: The final boss in Doom isn't really the hardest monster
    in the game. To take out these b#$%@!& use the BFG9000 3 times to finish
    Cyberdemon: The boss at the end of the second episode, to kill the
    Cyberdemon, use the rocket launcher or BFG9000 while dodging his
    Abbreviations and definitions
    N,S,E,W,NW,NE,SW,SE = North, South, etc. North is up on the map, east is 
    right, etc.
    Jump = Run off the edge of a platform.
    Activate = Press the use (default is spacebar) button. If I say something 
    be activated it generally looks different then its surrounding walls.

    E2M8- Tower of Babel
    Defeat the Cyberdemon Lord
    i. Press any of the switches and head through any of the
    opened doors.
    ii. Go outside and kill the Cyberdemon.
    There are 3 ways you can defeat him, they are listed as
    1. Get the rocket launcher and shoot volleys of rockets
    at him, strafing to avoid the Cyberdemon's rockets. As
    you may have heard before this is a good level to
    practice strafing.
    2. Get out the chaingun or pistol and fire at the
    Cyberdemon through the small gaps between the pillars
    at the corners of the central building. Your shots should
    pass through but the Cyberdemon's won't. This takes a
    while though.
    3. Try to get the Cyberdemon stuck in one of those supply
    rooms, and go into the opposite room and fire at him so
    your shots fire over the pillar with the door opening 
    switches. I have seen this in a demo and have managed to
    do it, however, occasionally the demon may manage to
    fire over it.
    Be careful on Ultra-Violence as the Lost Souls can
    distract your marines shots.
    E2M9- Fortress of Mystery
    i. Go through the door to the E

    you may want to kill most of the monsters, or
    get the monsters to attack each other.
    iii. Press the skull switch, get the key, then
    I think you can finish this stage without too much
    Episode 3: Inferno
    This last episode can get very messy, especially on Ultra-Violence
    where the first levels will be real pains with just a pistol. Not
    only this, but some of the levels are difficult in puzzles too.
    However, I guess it is set in Hell, so...
    E3M1- Hell keep (Keep?! The only time it's well protected is
    on Ultra-Violence!)
    i. Press the switch in front of you.
    ii. Head N and press the left-hand switch to open the door
    iii. Head NE through a door to another courtyard.
    iv. Head through the E door and follow the long hallway
    to an area with some red pillars.
    v. Head N through two doors then enter the teleporter to finish
    the level.

    i. Keep to the left-hand wall at the start and just keep running 
    along it until you find the blue key.

    reach the blue door.

    and head N into the exit.

    Level 'ratings'
    These are my level 'ratings' which should be self-explanitory.
    These are just my personal fellings however, and if you think
    something really different you can e-mail me and i'll put your
    suggestion up.
    E1M1: For the first level, this is rather decent and lets
    you get used to the controls without too much difficulty.
    The layout is decent too, although i really wouldn't call
    it a hanger...
    Layout: 8/10 (10 is best). Difficulty: 1/10 (both puzzle
    and enemy difficulty, averaged out of all skill levels)
    E1M2: This level is a little small but it isn't too bad, although,
    as with nearly all doom levels, it doesn't represent what
    the name says.
    Layout: 8/10. Difficulty: 2/10
    E1M3: A level that is close to what its title describes, but
    not exactly. This level isn't bad in both difficulty or layout
    but i really think something is lacking...
    Layout: 7.5. Difficulty: 4/10
    E1M4: A large(ish) level that is non-linear and contains
    many secrets, this level can keep you occupied if you play
    it properly.
    Layout: 7. Difficulty: 4/10
    E1M5: A reasonable level but it really lacks something
    that I'm not really sure of. The level is rather linear and
    can get boring after you've played it a few times.
    Layout: 6. Difficulty: 5/10
    E1M6: This level is really not one of my favourites.
    This level requires you to run all over the place just to
    press switches and get keys (although I suppose all
    the doom levels are like that, but still...). It's not the
    worst doom level, but it's not too far from it.
    Layout: 3. Difficulty: 4.5
    E1M7: This level gets a bit boring as you can get lost
    rather easily, and just like the last level, it just doesn't
    appeal to me.
    Layout: 5. Difficulty: 5
    E1M8: I don't mind this level, and it is a pretty good
    level for the last one. Short and sweet, that's what all
    final levels should be.
    Layout: 9. Difficulty: 4
    E1M9: This level is not too bad but it can get annoying
    at times, unless you have some good weaponry. The
    layout is pretty good but the trench ending isn't something
    I liked.
    Layout 7. Difficulty: 5.5
    E2M1: Not a bad level but is a little hard at times (on 
    Ultra-Violence), unless you're a good Doom player.
    Layout: 8. Difficulty: 4
    E2M2: This level is a little strange in layout terms
    but in difficulty it's not too bad, especially because
    of all the ammo lying around.
    Layout: 6. Difficulty: 4
    E2M3: The layout for this level is terrible in my
    Opinion, and there is NO way this could be considered
    a refinery. The level is of average difficulty, mainly
    because of that baron of hell.
    Layout: 3. Difficulty: 5
    E2M4: I don't like this level very much at all. It's 
    absolutely terrible. I only play it so I can say I finished
    Doom without cheating and not be lying.
    Layout: 3.5. Difficulty: 6
    E2M5: This level, as I said before, is very mazey, but
    I don't hate it as much as some of the other maze levels.
    In fact, this level isn't half bad, but if you don't know what
    you're doing, be careful.
    Layout: 5.5. Difficulty: 6.5
    E2M6: I HATE THIS LEVEL! It's a pathetic maze-like level
    which although is 'atmospheric' I just don't like it at all.
    Really. The level is great for deathmatch though, which
    saves it somewhat.
    Layout: 4. Difficulty: 7.5
    E2M7: This level is a bit big but isn't too bad too explore
    due to the fact it's non-linear. It can be a bit hard though,
    especially if you get surrounded in the 'demon room.'
    Layout: 6. Difficulty: 7
    E2M8: A great layout for a boss level, but on Ultra-
    Violence, those lost souls can really get in your way,
    but at least they block the Cyberdemon's shots.
    Layout: 9. Difficulty: 6
    E2M9: A great level for practicing battling against
    a large amount of enemies, and I find it a fun, reasonably
    easy level to play.
    Layout: 9. Difficulty: 2
    E3M1: A little difficult for the first level, but there is enough
    room to move about, except in the twisty demon passages.
    Health can be a problem here, and so can ammo so that's why
    I consider it quite a difficult level.
    Layout: 8. Difficulty: 8
    E3M2: Due to the amount of room there is on this level, and the
    fact that you can easily run around the enemies, this level is
    hard, but not quite as hard as the previous level.
    Layout: 7. Difficulty: 6.5
    E3M3: This level is like some sort of castle that is populated with
    some tough demons such as barons of hell. You can get lost in
    this place sometimes, so you must be careful.
    Layout: 6.5. Difficulty: 8.5
    E3M4: This is a pretty big house, and contains quite a few 
    enemies. There is enough ammo and health to keep you going
    however, unless you try to fully clear the level out on Ultra-
    Layout: 5. Difficulty: 6.5 
    E3M5: Hmmm, I don't like this level. The courtyard idea wasn't
    too bad, but the fact that you can't really finish the level by going
    around the edge can be annoying.
    Layout: 4. Difficulty: 7
    E3M6: This level is very open and avoiding the enemies is easy
    enough, but on Ultra-Violence the blue key is VERY hard to find,
    unless you are very thorough.
    Layout: 6. Difficulty: 3-5
    E3M7: This level is not very good as it involves a lot of running
    around, and getting rad suits. I don't really like this level very
    much and cannot give it any good comments.
    Layout: 4.5. Difficulty: 6
    E3M8: This is another good boss level, but there isn't much cover,
    and when you're being shot at by a super-chaingun, you really
    want to hide somewhere.
    Layout: 7. Difficulty: 5
    E3M9: This level is pretty hard, and the layout is just like
    E3M1 but has a few extra rooms. Beware of the Cyberdemon!
    Layout: 8. Difficulty: 9
    I don't plan to do an Episode 4 'rating' as I don't like that episode
    much. If anyone out there does want to do one, feel free.
    That's all for now. I may fix this FAQ up a bit, but I'll
    probably be concentrating on my Final Doom or
    Icarus walkthrough.
