Cheat code

There are various cheat codes in Doom. They are activated by typing the correct series of letters in-game (some source ports support activating additional cheat codes from the console).

The cheat codes were added to the game by Dave Taylor.

How To Use
To use the cheat codes in the game, just type the code while playing. If typed correctly, a message should appear at the top of your screen, and your status bar, face, and ingame view may also change depending on the nature of the code. All the codes for the original game should also work for all ports, unless otherwise noted.

Beware, on some ports and in the original exes, if your keyboard is not a QWERTY, the cheat codes may change. For example in France idkfa may be idkfq.

Doom
See SPISPOPD for the origin of the code.

How To Use
Enter these cheat codes the same way you would, with regular Doom cheat codes.

Boom
These cheats are available in the Boom source port:

How To Use
In order to use cheat codes in ZDoom, the variable "sv_cheats" must be set to "1" (true). To set this variable, run ZDoom, and access the console. (To access the console press the tilde "~" key). Then type "sv_cheats 1". Then, use any ZDoom specific cheat by typing them into the console.
