added an enemy list at the end of this FAQ, which shows how many enemies there

object indicators on the Automap.

Invincibility Sphere: Whenever you pick up one of these, you will become 
Invincible for a short amount of time, so enemies cannot hurt you. Your GameBoy 
Advance screen will also turn blue, and when it goes back to normal, you're no 
longer Invincible. 

Berserk Pack: Whenever you pick up one of these, your screen will go red for a 
few seconds. Picking up a Berserk also powers up your Fist, knocking out most 
enemies quickly. These powers up your Fist for up to the end of the level. If 
your health is below 100%, this will set your health to 100%.

100% to your health. You can get up to 200% health maximum.

when you pick these up.

Keys: These appear as normal keycards, or as a little skull. Keys are in 3 
colors: Red, Yellow, and Blue. They open up the locked doors in the levels, 
which are Red, Blue, or Yellow (ex: If a door has blue bars to the sides of it, 
it is a Blue Door).

===========
4. Enemies
===========

Zombiemen: The first and weakest enemy you'll find. They attack you with their 
Pistol, and you can grab their Clips when they die. Any weapon will do on 
these. First found on E1M1: Hanger.

Shotgun Guy: Like the Zombiemen, but these are darker, and tougher. They use 
their Shotguns for attacking, and they can be powerful at hard skill levels. 
Use any weapon on these. On hard skill levels, they'll be first found in E1M1: 
Hanger, and E1M3: Toxin Refinery on easier skill levels.

Imps: These are small brown enemies. They fire fireballs at you, which can be 
dodged. Use at least a Pistol to take these down. First found in E1M1: Hanger.

Demons: These are pink bull-like enemies on two legs. They bite you for 
attacking (so they'll have to get up close to attack), which can really hurt 
you on hard skill levels. Use a Chainsaw, or anything powerful than a Pistol to 
take these down. First found in E1M3: Toxin Refinery.

Lost Souls: These are annoying little enemies on fire that fly. They charge at 
you for attacking, and they can get very annoying on hard skill levels. Use a 
Shotgun or better to take these down. First found on E2M1: Deimos Anomaly on 
easy skill levels, and E2M2: Containment Area on hard skill levels.

Cacodemons: Like Lost Souls, these fly in the air, but these have one eye, and 
are big and red. They shoot fireballs at you, which can be easily dodged. First 
found in E2M1: Deimos Anomaly on hard skill levels, and E2M3: Refinery on easy 
skill levels. Use a Chainsaw, Shotgun, or anything more powerful to take these 
down.

Baron of Hell: The most powerful enemy you'll find in the game. They throw 
green slime balls at you, which can be easily dodged. These are brown, and they 
are tall and walk on two legs. Use a Rocket Launcher or better to take these 
down. First found in E1M8: Phobos Anomaly.

===========
5. Weapons
===========
Chainsaw: When you pick this up, it replaces your Fist (except if you picked up 
a Berserk Pack). First found in E1M2: Nuclear Plant. Use this on Demons and 
Cacodemons, as they won't be able to attack you when you attack them with this 
weapon.

Fist: Yes, your fist. Don't use this, it's really weak. Only use this when you 
get a Berserk Pack, where it becomes really powerful, and it will be powerful 
enough to take down any enemy. You'll always have this weapon with you.

Pistol: Like the Fist, you'll always have this weapon as well. Use it on 
Zombiemen, Shotgun Guys, and Imps. Tougher than a normal Fist, but still weak. 

Shotgun: You find this weapon early, and it's powerful. First found in E1M1: 
Hanger. Use this on any enemy except a Baron of Hell, as this can take down 
nearly any weak enemy in 1 hit. 

Chaingun: This uses Pistol bullets, but this is more powerful and fires 
multiple rounds at once. Use this on any enemy. First found in E1M2: Nuclear 
Plant.

Rocket Launcher: Another powerful weapon you'll find early. Use this on any 
enemy, but watch out: If you fire it and the Rocket detonates in your face, you 
will be hurt as well. Can knock out any weak enemy in 1 hit. First found in 
E1M3: Toxin Refinery.

Plasma Gun: Fires multiple rounds like the Chaingun, but this is more powerful. 
It fires out blue Cell projectiles, and use this on anything. First found in 
E2M1: Deimos Anomaly.

BFG9000: The most powerful weapon in the game. It uses cells to fire, and it 
fires out 1 big energy ball, which is 40 cells. Use this on anything, as it can 
knock out ANY enemy in 1 hit. First found in E2M3: Refinery.

===========
6. Options
===========

These options come up when you pause the game:

New Game: Starts a new game. First you pick which episode you want to start at, 
and then which skill level. The higher the skill level, the more enemies appear 
and the more damage you'll take.

Load Game: Loads a saved file in any of the 4 Save Slots.

Options: When you select this, a list of options will pop up. Here they are:

Set Controls: A is the default. You can choose six other configurations too for 
different controls.

Sound Effects: Use this to turn the sound effects on and off.
Music: Use this to turn the music on and off.

Autorun: Turn this on so you will always run. Keep it on all the time. You'll 
need to use it to get past areas of this game.

Brightness: Allows you to control how bright the game is between 6 different 
brightness levels.

Dynamic Lightening: Choose if you want Dynamic Lightening or Static Lightening. 
These have an effect on the brightness of the game as well.

Ok, back to the main Options:

Quit Game: Only pops up during gameplay. Use this to return to the title 
screen.

Episode 1: Knee Deep in the Dead
<><><><><><><><><><><><><><><><><>

------------
E1M1: Hanger
-------------

Your quest to save the two moon bases on Mars starts here. Once you start the 
level, kill the Zombieman across from you if you're playing on Ultra Violence. 
Now go through the opening to the left. In here, get the Armor at the top of 
the stairs and kill the Shotgun Guys if you're playing on skill 4, and then get 
their Shotguns. Now leave this room. Back in here, go through the opening to 
the left, and then follow this hallway to a door, and then open it and go 
through. In here, kill the Zombiemen across from you and knock out the Shotgun 
Guys if you're playing on skill 4. Now go through the opening at the other end 
of the room.

Now follow these stairs to a zig zag hall. Kill the Zombiemen and Imps here and 
then go through the opening at the other end of the room. In here, there is a 
door in front of you. Before opening, open the hidden door on the wall to the 
right gray wall to the right and it will open like a door, so go through it. In 
here, follow this hallway outside and knock out the Shotgun Guys on skill 4. 
Grab the health and ammo while you're at it. Out here, get the MegaArmor and 
then leave this room. Back in this small hall, exit this room. Now, open the 
door to your right and go through it.

In here, knock out the Imps and Zombiemen and head to the exit door. Before you 
open it, turn around and leave this room. Remember the platform with the Imps 
on it in here? It has lowered and revealed an opening, so go through. In here, 
get the Shotgun, the Shotgun Shells, and the Medikit, and then go back to the 
exit door. Open it and go through, collect the health, and then hit the exit 
switch.

--------------------
E1M2: Nuclear Plant
--------------------
 
Once you start the level, head right and you will see a door. Instead, turn 
left. See that brown part of the gray wall to your left? Open it like a door 
and then go through. In here, get the backpack and hit the switch, and then 
leave this secret room. Back out here, there are two doors across from you. 
Open the one to the left and go through, knocking out all the Zombiemen. In 
here, head up the stairs and you will see an opening to your left, so head into 
it. Out here, there will be a ton of Shotgun Guys on the Ultra Violence skill. 
Kill all of them and then grab the Soulsphere and Chaingun in this room, and 
then leave.

Now, head up the stairs. At the top, kill the Zombiemen and then grab the Red 
Key to the right. Once you do that, head back down the stairs to the door, open 
it, and leave this room. Back in here, kill the rest of the Zombiemen, and then 
open the red door at the other end of the room, and then go through it. In 
here, kill the Zombiemen and head up the stairs across from you. At the top, 
follow this pathway into an opening, and then go through it. In here, grab the 
Medikits, and go straight. The floor you're on will lower. Down here, mow all 
the Zombiemen and Imps down with your new Chaingun, and then hit the switch at 
the other end of the room.

Two openings will be revealed, but go through either one. In here, head right 
down the stairs. At the bottom, open the exit door and go through. In here, mow 
everyone down with the Chaingun, and then hit the exit switch at the other end 
of the room.

---------------------
E1M3: Toxin Refinery
---------------------

Once you start the level, open the door in front of you and go through it. In 
here, wipe out all the Shotgun Guys, Zombiemen, Imps and Demons with your 
weapons, and then follow the left hall to a door. Once you get to it, open it 
and go through it. In here, shoot the barrel in front of you and it should 
explode, killing any enemies near it. From here, head up the stairs to the 
right. Up here, head down the stairs to the left. Down here, turn left. Shoot 
the barrel and when it explodes, a ton of enemies near it will be killed. Now 
hit the switch, and this will open a wall where the first barrel was. Go to the 
new opening.

Before going in it, clean the area in front of you with a Chaingun or Shotgun 
to get rid of all the Shotgun Guys in front of you. Now, head up the stairs and 
listen carefully. You should here the sound of an elevator being dropped. Wait 
for it to rise and also, use this ASCII map to help:

Say the X is you. A2 is one hidden lift and A1 is the other. Leave and reenter 
this room to lower the lifts, and then RUN to A2, killing any Imps, Shotgun 
Guys or Demons in your way. Once you get to A2, get on it and walk up to the 
wall and it will open, so go through. In here, follow this hall to a pillar, 
killing any Imps in your way. Once you get to the pillar, hit the switch and it 
will lower, so grab the Soulsphere. Now turn around and leave this room, and 
lowering the lift. A1, which is right across from you will be lowered again, so 
run to it and get on the lift.

When it rises, walk up to the wall and it will open, so go through. In here, 
kill the Imps and then grab the Rocket Launcher and Box of Rockets. Once you do 
that, get in the slime river and go through the opening, following the hall to 
a switch. Once you get to a switch, hit it, get the backpack next to you, and 
then open the green door to your right. In here, follow this hall to a silver 
platform and it will lower so get on it. Now ride it to the top and open the 
door in front of you. In here, get the Armor in front of you and the floor 
you're on will lower.

Down here, head up the stairs to your left. At the top, turn right and open the 
door to your right and go through. You'll be back at the level's starting 
point. In the center of the room, a new bridge has been created, so go across 
it. Walk up to the wall in front of you and it will open, so go through it. In 
here, head straight and another set of walls will open. If you're playing on 
Ultra Violence, bust out your new Rocket Launcher and clean the room of 
Zombiemen and Shotgun Guys. Now head straight and another set of walls will 
open. 

In here, follow this hallway to the exit door, and then open it and go through 
it. In here, lower the lift to your left, get on it, and ride it to the top. Up 
here, kill the Imp, get the Box of Rockets, and then turn around and drop back 
down to the floor below you. Down here, hit the exit switch. This switch will 
take you to the secret exit instead of the normal one
--------------------
E1M9: Military Base
--------------------

Doesn't look like a Military Base to me. Once you start the level, there will 
be a cage of Imps and barrels. Launch one Rocket into the cage and it should 
kill all of them. Now from where you started the level, follow the left hand 
wall to an opening. Once you get to the opening, kill the Zombiemen and Shotgun 
Guys in front of you, and then head down the stairs. Down here, kill all the 
Imps, Shotgun Guys and Demons, and then get the Yellow Key in the middle of the 
room. Once you grab it, turn around and head back up the stairs.

Back up here, kill the rest of the Zombiemen and Shotgun Guys, and then go 
through the opening to your right. In here, head down the stairs. At the 
bottom, turn left and you will be facing a corner of this room. Walk up to it 
and the floor you're on will lower. Down here, get the Chaingun and health in 
the middle of the room, and then turn around and go back to the lift, and ride 
it back up to the room. Back in here, go through the opening to your left, and 
then head down the stairs. At the bottom, open the Yellow Door and go through. 
In here, one nice Rocket can take care of most of the enemies, and another gun 
can finish the rest off. 

From here, get the Red Key in the middle of the room. A wall will open in front 
of you, revealing some Shotgun Guys and Imps. A fresh rocket should take care 
of most of them, and a different weapon can knock out the rest. Get the Medikit 
and Stimpacks if you need them, and exit the room the way you entered. Back in 
here, open the Red Door at the other end of this room, and go through it. In 
here, take out most of the enemies with a simple rocket, and then take care of 
the rest. At the other end of the room is an opening, so go through it. In 
here, destroy the barrels and they will explode, revealing a switch, so hit it.

Now, leave this room and you'll notice the pillar in the middle of the room has 
lowered, revealing the Blue Key and Demons. Kill all the Demons with a 
Chaingun, and then grab the Blue Key. From here, go through the opening to the 
left. Back in the level's starting point, go through the opening at the other 
end of the room. In here, open the Blue Door in front of you and go through it. 
In here, you will see a ton of Imps and Shotgun Guys across from you on Ultra 
Violence. One perfect rocket can get rid of all of them. Now drop down to the 
pit below you.

Down here, follow this hall and you will see a platform with an Imp on it, but 
be quick because the floor you're on is toxic. Once you see a platform, get on 
it and hit the switch. Now turn around and a wall behind you will open, so go 
through it. If it closes, go back to the platform and it will open again. Now, 
in here, follow this hall to a lift, killing the Imps in your way. Once you get 
to the lift, lower it, get on it, and ride it to the top. Up here, open the 
door in front of you and go through. Now cross the bridge to your left and then 
hit the exit switch. 

----------------------
E1M4: Command Control
----------------------

Once you start the level, open the hidden door on the wall to the left and they 
should open like a door, so go through. In here, get the Backpack, Box of 
Shotgun Shells, and then leave this room. Back in here, open the door to the 
left and go through it. In here, eliminate the Zombiemen and Imps. There are 
also 3 openings in here. Go through the one on the left and you'll be in a big 
room. In here, drop down to the pit in front of you. Down here, go left and 
you'll be in a small room. Kill the Shotgun Shells, get all the items, and hit 
the switch. The lift on your right will lower, so get on it and ride it to the 
top. Up here, get the Soulsphere, and drop down to the floor below you.

Down here, go back through the opening to your left. In here, go through the 
opening to your right and head up the stairs. At the top, walk up to the door 
in front of you and they will open. In here, kill all the Imps and get the Blue 
Key. If the 4 doors on you close, use the switch to open them back up. Back in 
here, go through the opening in the west part of this room (use the Automap by 
pressing Select to help). In here, go through the opening to the left. In here, 
knock out the Shotgun Guys and open the Blue Door to the right, and then go 
through it.

If you're playing on a high skill level, watch out. This hall is pretty dark so 
an Imp or Demon can come out and attack, so be on the lookout. Now, go all the 
way right until you stop at a wall, killing all the Imps and Demons you see. 
Now go through the opening to the right and follow the left hand wall to a big 
room. In here, kill the Imps and Demons, get the Yellow Key, and then go 
through the opening and up the stairs. At the top, hit the switch, and then 
open the Yellow Door next to you. In here, kill the Shotgun Guys and then use 
the stairs to cross the platform and get to the exit door. Once you get to it, 
open it and go through. In here, hit the exit switch.

-----------------
E1M5: Phobos Lab
-----------------

Once you start the level, cross the slime pit in front of you and go into the 
opening across from you. In here, the Shotgun Guys and Imps and then head all 
the way right until you stop at a wall. Now go through the opening to your 
left. In here, walk straight and a bridge in front of you will rise. To get to 
it, turn around and follow the right hand wall to a staircase. When you get to 
it, go up it. At the top, kill all the Zombiemen and get the Medikit.
 
See that barrel? Destroy it and open the secret door it was in front of. In 
here, get the Shotgun and the Box of Shotgun Shells. Now turn around and go 
through the opening to the right. In here, cross this bridge to the opening and 
go through it. In here, kill the Shotgun Guys and Imps and follow this hall to 
the Yellow Key. Once you get to the Yellow Key, turn around and leave this 
room. Back out here, drop down into the pit below you. Down here, see that 
blood corpse in front of a wall? That is a hidden door, so open it and go 
through it.

In this secret room, collect the MegaArmor, Rocket Launcher, and the Box of 
Rockets. Now go through the opening to the right, and walk forward. The wall 
will open in front of you, so go through it. Back in here, open the door to 
your right and go through. In here, kill all of the Zombiemen and Shotgun Guys 
across from you and to your left, and then follow the left hand wall to the 
Yellow Door. Once you get to it, open it and go through. In here, walk forward 
and drop down to the floor below you. Down here, kill all the Demons, Imps, and 
Shotgun Guys in front of you.

Now, head right and follow this hall until you see a huge slime pool to your 
left. Cross it and hit the switch at the other side. Now, two pillars will 
lower revealing Imps and Zombiemen. Kill them all. Now, see that opening with 
the Medikit in it across from the slime pit? Go into it. Press B on the 
wall to open it. Get the hidden Radiation Suit and open the secret door to the 
left. Get the Chainsaw and then open the door in front of you, and you'll be 
outside. Get the Soulsphere and head back inside. Back in here, follow either 
hallway back to the lift, killing any Imps, Demons, or Shotgun Guys you see.

Once you get back to the lift, lower it, get on it, and ride it to the top. 
Back up here, leave this room. Back in here, go through the opening across from 
you. In here, head up the stairs, killing any Shotgun Guys or Demons in front 
of you. At the top, go through the opening to the left. In here, kill the Imps 
and then head into the opening to your right. In here, kill the Shotgun Guys 
and in this room, find a switch. Hit it and the wall will open like a door, so 
go through. In here, follow this hallway until you get to the Blue Key, killing 
all of the Imps that you see. Once you get to the Blue Key, grab it.

While you are in this room, kill all the Zombiemen and Imps, and then hit the 
switch. Now turn around and head down the stairs in front of you. Down here, 
open the Blue Door in front of you, and go through. In here is a very dark 
hallway. Follow either right or left hand wall to the exit door, killing any

E1M6: Central Processing
-------------------------

Once you start the level, go through the opening in front of you. In here, go 
through the opening to your right. Now, kill all the enemies in front of you 
and get the Red Key at the other end of the room. Then turn around from where 
the Red Key was, and go all the way straight, killing any Shotgun Guys, Imps, 
or Zombiemen in your way. Once you get to two Red Doors, enter either one of 
them. Now, follow the hallway to an opening to your right/left (depending on 
which door you entered), killing any Shotgun Guys and Zombiemen in your way.

Once you get to the opening, go through it. In here, kill the rest of the 
enemies and get the Blue Key. Now drop down to the slime pit below you. Down 
here, head right to the corner of the room and you will see a Radiation Suit. 
Grab it and then turn around. See that opening across from you? Go in it. In 
here, walk straight and the wall in front of you will lower, so get on it and 
ride it to the top. Up here, grab the Soulsphere and drop back down to the pit. 
Down here, go through the opening at the other end of the room, and collect the 
MegaArmor next to it. In here, follow this hall to a switch, collecting the 
Health and Armor Potions.

Once you get to the switch, pick up the Box of Rockets and hit it and it will 
open like a door, so go through it, and you will be back at the level's 
starting point. Back here, open the door at the other end of the room, and go 
through it. In here, go through the opening to your right, killing any Imps in 
your way. Once you get to the opening, go through it. In here, remember that 
pillar to the right where the Imps are on. Now walk all the way straight to the 
Blue Door. Once you touch it, turn around and you'll find the pillar has 
lowered, revealing an Opening. Use a Rocket Launcher or Chaingun to wipe out 
all the Demons, Imps, and Shotgun Guys, and then go through the opening.

In here, open the hidden door in front of you and go through. In here, collect 
the Rocket Launcher and Invisibility Sphere, and then open the Blue Door in 
this room. In here, grab the Yellow Key and head down the stairs to the right. 
Down here, walk straight and the door in front of you will open. Now turn 
around and open the Blue Door (it is the unusual looking green wall to the 
left), and in here, exit this secret room. Back out here, grab the Radiation 
Suit. Now, go to the other end of the room towards the opening in the slime 
pit. 

In the opening, follow this hall to a door, killing all the Imps in your way. 
Once you get to the door, grab all the goodies you want - health, ammo, and a 
backpack. Now if you're playing on Ultra Violence, bust out your Rocket 
Launcher, and open the door. Now, drop down to the floor below you. Down here, 
launch a few rockets at the large group of Shotgun Guys and they should be all 
gone. Now grab their Shotguns. See that pillar the Soulsphere is on? Lower it 
like a lift and get on it. On here, get the Soulsphere and ride it to the top. 
Now, open the wall in front of you and go through it.

In here, kill all the Zombiemen, Shotgun Guys, and Imps in front of you and to 
your left because you're about to be slaughtered if you don't kill them. Now go 
through the opening to the right. In here, kill the Imps, get the Box of 
Shotgun Shells and Stimpack, and hit the switch. Now turn around and go into 
the room with the slime pits. In here, pump 3 rockets into the opening to the 
right and all the enemies should be gone. Now go through the new opening. In 
here, kill the Imps and Demons and head down either staircase. Down here, 
follow them to an opening because they lead to the same room. In here, go 
through the opening next to you, kill the Shotgun Guy and hit the switch.

Now, walls will open, revealing Imps, Demons, and Shotgun Guys. Clean them up 
with all you have, and then get the leftover ammo and health once they're all 
one. From where the switch is, go into the new opening to the right. In here, 
open the exit door and go through. In here, grab the Medikits and hit the exit 
switch.

and then get on it. It will start rising, so turn left. See that slime pit in 
front of you? RUN into it. Down here, get on the platform and grab the Medikit. 
Now, go through the opening and get the Backpack, and the wall to your left 
will lower, so go through it.

Back in here, head back up the stairs. Walk past the pillar and then go through

of you, killing the Zombiemen in front of you. At the top, go through the 
opening in front of you, and then follow this hall to a dark room, killing all 
the Imps, Zombiemen, and Shotgun Guys in your way. Once you get to the dark 
room, use a Chaingun or Rocket Launcher to kill all Imps, Zombiemen, and 
Shotgun Guys in this room. Once the enemies are dead, hit the switch in this 
room. Now, turn around and follow this hall back to the opening. Back in here, 
turn right. Kill all the Zombiemen, Shotgun Guys, and Imps in front of you, and 
then go into the new opening in this room.

left. In here, open the door across from you, and go through. In here, go all 
the way straight to the other end of this room. Over here, hit the switch in 
front of you, and the wall will lower like a lift. So get on it, and ride it to 
the top. 
 
Up here, walk straight, and the doors in front of you will open, revealing 2 
Barons of Hell. Kill them both. Here are some tips:

1. If you have enough Rocket Launcher ammo, use the Rocket Launcher. A few 
Rockets will take down both of them.

2. Use L and R to strafe and dodge their slimeballs.

3. If you don't have any Rocket Launcher ammo, use the Shotgun or the Chaingun 
to take them down, just make sure you have enough ammo.

Once you kill both Barons of Hell, the walls around you will lower, so once 
they're finished lowering, drop down to the floor below you. Down here, open 
the door to the north, and go through. In here, hit the switch to the left, and 
stairs to the left will raise. Head up them. At the top, kill the Zombiemen,

is a Red Door in front of you. Before entering it, turn right and you will see 
barrels. Destroy them because you'll be teleporting right where they are and 
you don't want to kill yourself. Now, go back, open the Red Door and go through 
it. In here, walk forward and a pillar will lower, revealing a teleporter so 
step into it. You will be teleported right where the barrels were. From here, 
head left and follow this hallway to the Blue Key. When you get to it, grab it 
and drop back down to the floor below you.

Down here, head straight and go through the opening to your left. In here, head 
up the stairs. At the top, head left and then turn right and you will get to 
the Blue Door. Now open it and go through it. In here, kill the Imps in front 
of you, and then get the Yellow Key at the other end of the room. Now, turn 
around and you will see some doors open, revealing Imps and Cacodemons. Kill 
all of them and go through the opening to the right of the Blue Door, in here, 
hit the switch in front of you and it will open a door to the left, so go 
through it. Back in the level's starting point, open the Yellow Door at the 
other end of the room. Before entering it, get the Plasma Gun and Energy Cell 
Pack to your right. Now enter the Yellow Door. In here, hit the exit switch.

------------------
E3M2: Pandemonium
------------------

Once you start the level, kill the Demon, and then head up the stairs in front 
of you. At the top, kill the Imps and then head up the stairs to the left. At 
the top, head right and follow this pathway until you get to a lava pit. Once 
you get to a lava pit, drop down it. Down here, go through the opening in front 
of you. In here, get the Blue Key to your left, and then head down the stairs 
to the left. At the bottom, grab the Invincibility Sphere, and then head back 
up the stairs into the lava pit. Back in here, follow the right hand wall to a 
BFG, and then grab it. Now follow this wall to a Medikit, and then to a second 
Soulsphere.

Now, quickly get out of the lava pit because it does 20% damage to your health. 
Once you get out of the lava pit, drop down to the floor below you. Down here, 
go through the opening to your right. In here, head up the stairs to your left. 
At the top, kill the Imps and Demons, and then open the Blue Door to your 
right, and then go through it. In here, kill all the Imps and then go through 
the exit door to your left. In here, step on the exit teleporter.

--------------------
E3M3: House of Pain
--------------------

Once you start the level, get the Rocket Launcher, Armor, and Medikit, and then 
kill the Demon in front of you. Now step into the teleporter he was in front 
of. In here, turn right and you will see an opening across from you, so go 
through it (watch out for the Imps and Demons). In here, follow the right hand 
wall until you get to a large room of Lost Souls with the Blue Key in it. Kill 
all the Lost Souls and get the Blue Key at the other end of this room. Once you 
grab it, turn back around and leave this room. Back in the wide open, turn 
right and you will see another opening to your right, so go through it.

In here, open the Blue Door at the other end of the room, and then go through 
it. In here, open the door at the other end of the room and go through it, 
killing any Demons or Cacodemons you see. In here, open the door to your left 
and go through it, killing any Demons. In here, use your BFG to clean sweep 
this room full of Zombiemen, Shotgun Guys, and Lost Souls. Once they're all 
dead, open the door at the other end of this room, and go through it. In here, 
kill the Imps and Demons and press Circle on the demon face symbol to open it 
like a door. In here, get the Soulsphere and the Red Key in the lava pit, and 
then leave this room. Back in this small room, leave it.

Back in this big room, turn left and you will see a door, so open it and go 
through it. In here, fall in the small pit across from you to get the BFG. Now 
hit the switch to get back to the floor above you, and then leave this room. 
Back out here, open the door at the other end of the room, and go through it. 
In here, press Circle on the wall to the right and it will open like a door, so 
go through it. In here, get the Medikits, the Box of Rockets, the Energy Cell 
Pack, and then go back through the door. Back out here, open the door to your 
right and go through it to leave this room. Back in here, open the door to your 
right and go through it.

Back in here, open the door at the other end of the room and go through it. In 
here, open the Red Door to your left and go through it. In here, head left and 
you will get to a door. Walk up to it and a wall will open to your right, 
letting out Demons. Kill them all. Now, to open the other door, see that tile 
next to the wall that opened? Facing the tile with the opened wall to your 
left, step in it and step out to the RIGHT. This should open both doors, if 
not, play around with the tile. Once you get to two doors opened, go through 
them. In here, follow this hallway to an opening, killing any Imps in your way. 
Once you get to the opening, go through it.

In here, turn right and kill all the Imps in front of you. Now go straight into 
the large room across from you. In here, you will see a platform above you and 
an opening to your right. Go through that opening to get onto the platform. On 
here, kill the Barons of Hell and grab the Yellow Key, and then drop down to 
the floor below you. Before opening the Yellow Door, there is a new opening to 
your right. Kill the Cacodemons and Imps and go in it. Collect all the health 
and ammo. Also grab the Invincibility Sphere (I don't know why they would put 
one in at the end of the level), and leave. Back in here, open the Yellow Door 
at the other end of the room and go through it. In here, hit the exit switch.

-----------------------
E3M4: Unholy Cathedral
-----------------------

Once you start the level, open either door in front of you, and then go through 
either one. In here, turn left and follow this hallway to a wall. On the wall 
should be a star, which is a door, so open it and go through it. In here, step 
on the teleporter in front of you, and you'll be teleported to the middle of 
the "courtyard" you are in. In here, a door next to you will open, revealing a 
Baron of Hell. Kill it and get the Box of Shells and Invincibility Sphere in 
the secret room. Now, go back to the center of the courtyard. In each corner of 
this room there are 4-pad teleporter sets. One will get you out of here and the 
other 3 won't. The one that will get you out of here is the teleporter set in 
the northwest corner of this room.

Use the Automap if you can't find it, and then step in it. In here, kill all 
the Demons in front of you. Once they're all dead, grab the Medikits if you 
need to, and you'll also note two doors at the other end of this room. One is 
to the right and one is on the left. Open the door to the right and go through 
it. In here, turn right and follow this hallway until you see a silver wall to 
the right. Next to the silver wall is a pillar with an opening through it. Walk 
through the pillar (the direction facing the door, not through your back facing 
the door) and the wall will lower, revealing an opening so go through it. In 
here, there is a switch in each corner of this room. Hit the switch in the top 
right corner and then go through the opening to the left.

A platform with the Blue Key will now lower, so grab the Blue Key, turn around, 
head right, and leave this room. Back in here, kill the Baron of Hell to your 
right. With your back against the opening you just came out of, turn right and 
follow this hall and you will stop at a wall. It should have a star symbol on 
it, which is a door. Open it. There should be a 4-pad set of teleporters. Step 
on it and it should bring you to the room where all the Demons used to be. Back 
in here, open the door to the left instead of the right this time. In here, 
kill all the Imps and follow this hallway until you see a Blue Door to your 
left. Once you see it, open it and go through it. In here, open the exit door 
to your left and go through it. In here, step on the exit teleporter.

===============
8. GBA Changes
===============

Here are some changes made from when Doom was ported on the GameBoy Advance:

1. Some levels were missing. I will also list levels that were changed around a 
bit. Here they are:

-------------------------------------------------------------------------------
Command Center: This is like the Command Center in the PC version, but part of 
the level was taken out and you cannot access the level's exit leading to the 
secret level.

Spawning Vats: Yes, this level is included in this game, but it is not like the 
PC version. It's very different.

Tower of Babel: Another level that was included, but it is very different from 
the PC version. 

Hell Keep: This was included too, but it is completely different and does not 
match the Hell Keep from the PC version in anywhere. 

Slough of Despair: This level is completely missing from the game.

Fortress of Mystery: This level is gone... but this is the level "Dis" in the 
game now. The same exact level under a different level, and this is the last 
level in the game too.

Mt. Erebus: This is like the Mt. Erebus in the PC version, but part of the 
level was taken out, so you cannot get to the exit leading to the secret level.

Warrens: Remember Episode 3's secret level? It's gone now.

Dis: This level is still here, the PC version is gone and now they replaced it 
with the level from Fortress of Mystery.

Containment Area: The same old PC version is still here, except parts of the 
level were cut off, changing the way to get to plenty of things.
-------------------------------------------------------------------------------

2. A few enemies were taken out of the game: The Spectre (the invisible Demon), 
the Cyberdemon (my favorite enemy), and the Spider Mastermind. These could've 
been reasons why Tower of Babel and Dis were completely changed. A lot of 
people were also saying that none of these enemies were in the game because 
they just used the Atari Jaguar Doom version for this which is the exact same 
thing to get this on the GameBoy Advance faster. Sad really. 

3. A few items were taken out of the game. The Invisibility Sphere and the 
Light Amplification Goggles. These were pretty decent items, and I don't know 
why they were taken out of the game. Also, Health and Armor Bonuses now give 
out 2% instead of 1%.

4. When enemies die, their corpses disappear. This was to keep the game moving 
at a fast speed.

5. The enemy's blood is now green instead of red. This was to make the game 
less violent, bring the rating down from an "M" to a "T", in an attempt to sell 
more copies. #4 has to do with this too. This game is also pretty rare these 
days, so pick it up if you got the chance. 

6. There are also no crushing ceilings in this game if you really notice. 
Levels in this game like Containment Area had crushing ceilings in the PC 
version, but since it was edited they are no longer in the level, as well as 
the entire game.

7. There is no Ultra Violence skill level in this game. Instead, Ultra Violence 
was named Nightmare in this game. But this nightmare mode is really easy, where 
you can cheat, enemies don't respawn, etc.

=========
9. Codes
=========

Here are some codes in the game for you to use if you want to cheat and have 
fun. To use these codes, you must pause the game, hold L and R, and then enter 
them.

Become Invincible: This will make you invincible from everything, including 
enemies, slime pits, and so on. To enter this cheat, hold L and R and press 
AABAAAAA and you will become invincible.

Invincibility Off: This is the cheat to turn your invulnerability off. First, 
pause the game, hold L and R and press AABABBBB. 

All Weapons: Pause the game, hold L and R, and press ABBAAAAA. This will give 
you all weapons and 500 of each ammo (even though the maximum isn't that high 
for most weapons).

Computer Area Map: Pause the game, hold L and R, and press BAAAAAAA (or just 
keep tapping A until you hear a sound). This will give you a full map for the 
level you are on, but it will not give you any object indicators.

Berserk: Pause the game, hold L and R, and press BABAAAAA to get yourself a 
Berserk. This will last until the rest of the level or if you die.

Temporary Invincibility: Pause the game, hold L and R, and press BBBAAAAA. This 
will give you invincibility, except this will be on a time limit.

Radiation Suit: Pause the game, hold L and R, and press BBAAAAAA. This will 
give you a Radiation Suit which is on a time limit.

Warp to next level: Pause the game, hold L and R, and press ABAABBBA. This will 
take you to the next level in the game, and it will obviously not work if you 
are on the last level. 

Warp 10 levels ahead: Pause the game, hold L and R, and press ABAABBAA. This 
will take you ahead 10 levels. Of course, this won't work after Map 14: Halls 
of the Damned as there are only 24 maps in this game. 

===============
10. Enemy List
===============


This is a list of enemies in each map. This shows how many enemies are in each 
map and how many of each enemy there is, thanks to Eric Liikala, a person who 
emailed me with the list. This is also for the Nightmare skill level. Anyway, 
here it is.
