Classic Codes:
In the console, type in any of the following to recieve a message: iddqd, idkfa, idfa, idclip, and idchoppers. You do not need to press enter to recieve the message.

Id Software PDA:
In the final level, Excavation Site, after going down the elevator into Hell, stick to the left wall. Make sure to stay to the left, or the final cutscene will trigger. You should come to a dead end with candles barely lighting a brick with the id logo in the center. Click this brick and a wall will open to your left. Walk inside the room to find the id Software PDA containing "Thank You" emails from the staff.

Super Turkey Puncher 3:
When you start the game, go through out the game and find the kitchen before 'all hell breaks loose' and in the corner of the kitchen you'll find an arcade game...On the screen is the face of the original Doom character...And he also makes the same faces when you punch and kill the turkey... Get a highscore of 25,000 or higher to get a mail on your PDA.

Colors!
You can customize your savegames and player names in color! Before typing in the name of your game/player type "^" without quotes and a number 1-0. Once typed, it will disappear and the cursor will change colors, indicating you did it correctly. You can use some letters too, but all the colors are in the numbers.


Custom Flashlights:
Doom 3 Custom Flashlight Textures
To make a custom texture for your flashlight in Doom 3, create a .pk4 file or copy one from your Doom 3 directory and clear it out. You can use a compression program such as WinZip to open and compile .pk4 files.
Once you have an empty .pk4 file to work with, create a folder named “lights” (without quotes). Grab the image you want to use and convert it to a .tga file (256 X 256 pixels is a good size). When you use the image it will be reversed, so mirror your image before saving it. Name the image flashlight6.tga, place it in the lights folder and make sure that folder goes in your .pk4 file. Then, rename the .pk4 file so it is the highest number in your Doom 3 directory. For example, if you have a pak005.pk4 file already, you will have to name your new flashlight texture file pak006.pk4 for it to take effect.
Once you have renamed the file, place it in your base directory and start the game.


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.


Skip beginning objectives:
At the very beginning of the game as soon as you start. Turn around and kill yourself by jumping off the platform. Click restart, and you will start in the elevator to the comm center with a pistol with full ammo, a shotgun, flashlight, and all hell breaking loose around you.
