Hints & Secrets

Nightmare Difficulty Without Finishing the Game

You will need to edit the DoomConfig.cfg file, located in the /Data/BASE folder. Make sure you backup the file before making any changes. Open the file with Notepad or other text editor. Look for the "g_nightmare" entry. If you haven't finished the game yet, you will see the number 0. Change it to 1, save, and nightmare mode will be unlocked.

View credits

Go to the Excavation Site level (final map) and get just before you enter the halls of Cyber-Satan. Walk to the left in the lower dungeons just before you reach the location where the wall breaks open and the intermission sequence of you discovering the final Boss starts. You will reach a dead end. Crouch and face the wall of the dead end. Look directly above the floor under a few protruding bricks to see the iD logo in the stone wall. Place your cross-hair on it. The same sound played when you use a computer will be heard. Click the iD logo. The brick it on will push into the wall with a scratching sound. A new path to your left will appear. Follow it to find a chamber lit by red light that has a huge horned skull on the back wall. Below the skull is a bloody pentagram with a PDA positioned in the center. Download the data from the iD PDA into your own to read . You will find e-mails from the game developers.

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.

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.

Defeating Sabaoth

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.
