Nightmare
mode: Complete the game once under any difficulty setting. When you
start on Nightmare Mode. you will start with the Soul Cube.
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 the Guardian Of The Soul Cube: 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, etc.
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.
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:
Defeating teleporting demons: When a demon teleports in (generally signaled by whisperings, a
red tint throughout the screen, and always red lightning in the location
where they will 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:
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 the devil.
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.
Hint:
BFG: 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:
Locker 666 warning: When you find locker 666, do not open it. There is a monster in
it, and nothing more.
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:
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:
Enpro Plant Sector 2 plasma room door code: 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:
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 Doom cover.
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.
