Doom Cheat Codes

To use a cheat code in most versions of Doom, one simply types the code while playing (this also applies while in automap mode). In the iPhone version of the game, touch the screen with four fingers at any time to bring up the keyboard. After the last letter has been entered, a message of acknowledgment will appear on the top of the screen. The status bar, face, and in-game view may also change, depending on the effects of the code.

Cheat codes are disabled on the "Nightmare!" skill level, except for the idclev and iddt cheats.

Cheat codes may be different on non-QWERTY keyboards. For example, in France, idkfa may be idkfq, because of the AZERTY keyboard layout commonly used there.

Doom95
The FH prefix in Doom95 cheat codes stands for the initials of Fred Hommel, the programmer who created the cheat codes.


 * 1) HALL refers to Jason Hall, CEO of Monolith, who requested that particular cheat (hence the "BY REQUEST..." message that displays when the code is executed). The actual damage done to each monster is 10,000 hit points.
 * 2) Upon typing the fhshh cheat the message "be vewy vewy quiet..." is displayed. This is a reference to Elmer Fudd's catchphrase "Be vewy vewy quiet, I'm hunting wabbits!", in the beginning of a Looney Tunes or Merrie Melodies animated short. Disabling the cheat will display the message "Achoo!" (the joke being you sneezed, and the monsters heard you).

Console version cheat codes
Cheat codes in the console versions are different due to the lack of a keyboard.
