Hint: Defeating the final Boss:
When you each the end Boss, do not bother wasting your
ammunition on him. Just stay away from him. Kill the Imps and
other demons and use the Soul Cube on him. If you are play in
co-op mode, shoot him. Use the Soul Cube on him about five or
six times. On the last time you will see an intermission sequence
of him dying.
Hint: Defeating teleporting demons:
When a demon teleports (generally signaled by whisperings,
a red tint throughout the screen, and red lightning in the location
where they will always appear), you will have a split second before
they are able to attack. Take a good weapon (for example, a shotgun
or chainsaw for imps and wraiths) and stand close by. For powerful
creatures, such as Pinkys, use a ranged weapon and stand at a
safe distance. Remember to save the game often
Hint: Defeating Archs:
In the "Security Monitoring" area, there
are several enemies including Archvilles and they bring Cherubs
to kill you. Run to the door at the far right and stay on the
"blocks". The enemies will not attack you (life and
armor are full and the Arch keep walking without attacking). You
can now take out your chain saw (to save bullets) and use it to
kill the Achs and Cherubs. [Screenshot]
Hint: Defeating demons:
The best way to kill demons is to use the plasma gun.
The plasma from the weapon can cancel the demon's plasma balls
that are often thrown at you. Because the plasma gun is rapid
fire, it will just keep firing until you release the trigger.
Hint: Defeating the Guardian Of The Soul
When fighting the Guardian Of The Soul Cube in hell,
do not bother shooting his body. This is a waste of precious ammunition.
Instead, blast his "searchers" with something with good
coverage like the chaingun, and he will have to spawn more. When
he does, a blue light will appear over his body. Shoot it with
the rocket launcher. Do this a few times and he will die easily.
Also, look in the room around the columns for ammunition, health,
When you are fighting the Guardian boss at the end of Hell, make
sure you save some rocket launcher ammunition and at least four
BFG cells. Note: When you kill the Guardian you will lose all
of your ammunition and guns -- there is no point of holding back
and trying to save ammunition. When you first see the Guardian,
use the rocket launcher to destroy all of its Seekers. As soon
as you kill the last one, charge up the BFG until four BFG cells
are charged into one shot. Fire it at the blue light above the
Guardian's head and it should die instantly. If done correctly,
you can kill it within twenty seconds without losing any of your
Hint: Defeating Sabaoth:
Note: A charged Soul Cube is requried for this trick.
As soon as you enter the room with Sabaoth, the door in front
of you will open and he will say "Welcome to mess hall".
Fire the five rockets and you might detonate the BFG shot that
he fires. After firing the five rockets he will be very close
to you. Stand still and fire your Soul Cube to defeat him. Note:
This was done under the normal difficulty setting.
Hint: Defeating Sarge:
Be prepared to die a few times. Beware of the edge
of the room, as you can fall off. Also, do not hide behind the
pillars for too long. They will open up and arc electricity periodically.
When you walk into the room, a giant bay door at the opposite
end of the room will open, revealing the "new and improved"
Sarge. As soon as that door opens a crack, start lobbing rockets
in there. After you score about six good hits without being splattered
by his BFG, break out the Soul Cube (that you should have charged
before entering the room) and let him have it. It should kill
him and heal you. Pick up the armor and ammunition around the
room before continuing.
in this section was contributed by Madison Nash.
Use the following trick to kill the new and improved Sarge much
easier. The key is to use the chaingun. It will blow up his BFG
bullets in his face. It will take about thirty seconds to kill
him in this way, and you do not have to use the Soul Cube. There
is is a video disc that you will get just before you fight him
that explains the BFG, and says that small arms fire will blow
up the chip in the ball of energy, making it explode instantly.
Hint: Defeating Imps:
If the Imp is jumping at you, blast it while it is
in the air with the shotgun to kill it in one shot. This is slightly
difficult to time.
As soon as an Imp has thrown a fireball at you, strafe around
it with your shotgun equipped. Get very close to the front of
the Imp and blast it in the chest. About 95% of the time, the
Imp will die.
When Imps shoot their energy ball at you, crouch underneath it
and run at them. Then, pump them in the face with the shotgun.
Hint: Mars City Underground: Save ammunition:
When at the end of Mars City Underground, kill the
scientist using the flashlight. After the intermission sequence,
hit him a few times until he explodes, changes into a skeleton,
and deteriorates. This saves ammunition and health. Do this before
he turns into a zombie.
Hint: iD Software PDA:
In the last level, just before you see the intermission
sequence before the devil, instead of going to where the sequence
begins the fight with the devil, go left. By the candles should
be an ID Software symbol on the wall. Go towards the brick until
you are touching it (you may have to duck). Press Action
(R) when your crosshairs are over it. The brick will go
inside the wall, and the wall behind you to the left will open.
In that room will be a special PDA from iD Software, saying thanks
for playing Doom 3 and other things. You can then fight
Get to the point during the last level at the end before you face
the Cyber-Demon. Instead of facing the Cyber Demon, go to the
left of where the rocks open up. Go under this rock and it would
say, "id". Select it, then look to the left. Rocks will
open. Go inside to get a PDA. It will read "id Software all
security clearance". All doors will now be unlocked.
Hint: Saving ammunition:
If you can avoid it, try not to use weapons like the
shotgun or others that have difficult to find ammunition on the
weaker zombies. The flashlight (if you are fast enough) or just
the pistol usually will suffice.
Hint: Save scientist:
In Delta Labs Level 3 South, almost as soon as you
enter a room, you will see a zombie marine shooting a scientist.
It is possible to save him using the Soul Cube in nightmare mode.
Make sure you have the Soul Cube charged. As soon as you enter
the room, use the Soul Cube on the marine. The scientist will
be unharmed and run away. You must be very quick when you do,
and it may require a few attempts.
Hint: Pumped up Soul Cube:
After you acquire the Soul Cube, equip it and wait
about one to two minutes. It will reveal its blades and spin for
a very short time.
At Chief M. Abram's office, the BFG is in the test
chamber when you are there to retrieve the plasma inducer. You
will see the BFG in a test chamber in a room that is locked. Enter
931 as the code to get the BFG.
Hint: Enpro Plant Sector 2 plasma room
The door code for the plasma room in Enpro Plant Sector
2 is 734. Be careful; leaving that room causes several creatures
to transport directly outside the door, but it is worth it.
Hint: Locker 666 warning:
When you find locker 666, do not open it. There is
a monster in it along with security armor. The code is "372".
and k lester.
Hint: Strange teleporting demon death:
When fighting a teleporting demon and he teleports
go to the place where he is going to, bring out the shotgun/ When
the red circle appears, shoot it. He will die inside the circle.
Hint: Safety from enemies:
To be almost invincible equip the chainsaw, hold R,
and run forwards. Anything in front of you will die in a few seconds.
This works for all enemies, but not especially well on enemies
with ranged attacks. It works best on Zombies, Imps, Cherubs,
Maggots, Wraiths, and in dark areas.
Hint: Bathroom scare:
After you have found the lost scientist and are returning
to the main building, find your way back to the bathrooms. Stand
in front of the mirror with your pistol then cycle through until
your shotgun then get very close.
Hint: Punching bag:
After defeating the spider Boss, go to southwest part
of the area. There will be a dangling body that you can punch
as many times desired.
Hint: Hidden message:
Go to Delta Labs Sector 4. When you get to the room
with the second chainsaw zombie, kill him, then face to the door
that leads into the teleporter room. Look to the left. You will
see a skeleton sitting in a corner. Hit it out of the corner and
you should see a message written in black, reading "YOU LOUSY
Hint: Classic Doom reference:
When you get to Mars City, go to the kitchen. Look
closely at the video game in the back to see a classic Doom
screen while you punch the turkey.
In the last few levels are stone tablets that feature the original
Glitch: Into the Hell hole:
Play the Primary Excavation level. Enable the "Invincibility"
code. When you fight the Cyberdemon, jump into the hole where
the Imps and Maggots are coming from. You will fall for awhile
until you get to the end, which is just where the hole comes to
a point. You must restart the level to exit.
Corey Dane Hoster.
Glitch: Devil death trap:
Enable the "Invincibility" code. When fighting
the Devil, run behind him and stay in the right corner. Turn around
and continue to riddle him with bullets. Eventually you will be
driven up the wall were the Devil will stop attacking. You will
continue to be killed but cannot move.
Glitch: Kill Counselor Swan and bodyguard
and get the BFG early:
During the "Alpha Section 1 West" level,
when you find the scientist with the PDA go past the glass crushing
thing. You will find the lost PDA. Drop down the hole and open
the door. Run to the next room and kill the two enemies. When
you reach the next room, shoot the two blue glass tubes with the
two monsters in the room. Note: Enable the "Invincibility"
code. Shoot the tubes and they will burst into flames instantly,
killing every enemy around you. Look to the left into the room
with the big window. You will see Counselor Swan and his bodyguard
running, and the flames will kill them. Go into the room where
you saw them and the BFG 9000 will be on the ground. Do not use
its ammo and go on to the next level. Go into the bathroom so
you can see yourself in the mirror, then pull out the BFG. It
will just be a black box in your hand and you cannot see it. Also
it will shoot boxes and explode.
Glitch: Fight Cyber Demon outside the ring:
Enable the "Invincibility" code during the
last level and get to the Cyber Demon. After the intermission
sequence you will be on his right-side. Instead of running around
in circles starting from his right side, move to his left side
as soon as the intermission sequence ends. Run backwards clockwise
until you reach the 3 o'clock position. Let him hit you to fly
out the ring. You will be on the lava and fire ground. Run back
to the 3 o'clock position and look for the Cyber Demon. Normally
he sees you no matter what, but if he does not, shoot him to get
his attention. Let him shoot you numerous of times or dodge his
rockets. Make sure you keep watching him. Between one and two
minutes of him shooting you while you are outside of the ring,
the Cyber Demon will teleport. Run on the other side of the outside
ring. You should see the Cyber Demon walking in mid-air, still
shooting at you. He can move and walk in your direction -- you
really cannot hide from him. He cannot step on you, but you can
shoot under him. No Imps or other demons can fight you while you
are outside the ring .
Glitch: Get Jack Campbell's BFG 9000:
Go to Alpha Labs Sector 1 West and enable the "Invincibility"
code. Enter the Hydrocon lab (the room with the two big tubes).
Quickly shoot one of the tubes and it will explode. Quickly look
in the window in front of the tubes to see jack dying. You can
now get his BFG 9000. If this does not work at first, try it again
Glitch: Disappearing person:
Play a co-op game on Xbox Live, In the room with about
two or three pretty big Pinkeys (they walk on all fours), there
should be a person lying against the wall. On one screen, it should
be there. On the other screen, it is not.
Glitch: Chainsaw zombie:
In Delta Labs Number 4, after you go through the bay
door that Betruger went through you will enter a hallway splattered
with blood with the words "suffer" and "die"
written on the wall in blood. In one of the long and empty hallways,
the lights go out as you walk down it. A chainsaw zombie will
appear for about half a second, then disappear. It will do this
all the way down the hallway until you reach the door and fight
Glitch: Bloody bullets:
Find an non-exploding drum of chemicals. Get a demon
in front of it. When you kill it, continue shooting. The drum
will get covered in blood instead of holes and singes. The machine
gun works best.
Glitch: Woman's corpse:
The first time when you see the flying skull, it should
be coming out of a woman. Her PDA says that she works on the plasma
gun project. The locker has a plasma gun in it. However, the girl's
corpse should still be there. Hit her with a flashlight and watch
her shake. She never goes away.
Glitch: See Mars City:
Go to the Communications Transfer Site 1 . Get to the
Mar's surface (outside) and enable the "Invincibility"
code. Kill all the spiders. Get to the lift but do not ride it.
Instead, go to your left and jump down the hole. Take out your
flashlight and look at the corner of the wall. You will see a
passage. Go in it, and you will be in a hall. Go all the way forward
of the hall then go right until you reach the wall. Then, go to
the corner of the location and you will see Mars City.
