Network cheat mode
Hold [Alt] and type "iddtiddtiddtiddt" in map mode.

Deathmatch cheat mode
Type "t" in the map to enter talk mode. Hold [Alt] and type "iddt" several times. This will reveal the entire map. Repeat the code to reveal all items. Repeating the code again will return the map to normal.

Wolfenstein
Type "idclev32 or idclev31" during game play to restart in a totally new level. When you complete one of those levels you will always start on the level suburbs and continue your Doom 2 game.

Cheat mode (command line)
Start the game with the "doom -devparm "<command line parameter> command line to activate the corresponding cheat function. Note: The parameters marked with an asterisk (*) do not require "-devparm" in the command line. Most of these parameters can be mixed and matched to create different effects. For example, start the game with the "doom -devparm -wart 1 8 -record demo01 -respawn" command line would record a demo on episode one, level eight, with monster respawn. Finally, press [F1] during development mode for a 256 color screenshot in .PCX format.

Romero's head
At the final level, enable the "idclip" code. Go through the wall with the demon head on it. You will see that the final boss is the head of John Romero, the co-creator of the Doom series.

Backwards sound
If you play the challenge made by the final boss backwards, you will hear him say "To win the game you must kill me, John Romero".

Get to Grosse level from Wolfenstein
When you get to the end of the Wolfenstein level, before you open the door to the final door enable the "idclip" code. Looking at the door, go into the right wall. Search around until you get to a room with another exit. Click the exit button in that room to go to a different screen with the message "You have found the super secret level. You should fly through this one." It says this because there is a Cyber Demon ahead.

Completing Icon Of Sin
In the last level, Icon Of Sin, there is a giant face that keeps launching "boxes" through a hole in his forehead. You must activate the platform. Take the invulnerability just in case, and while going up, aim with the rocket launcher at the correct moment so that the rocket goes through the hole from where the boxes appear from. Repeat this as many times as needed.
