Cheat code

Cheat codes in Doom engine games are entered by typing them during the game. The cheat system assumes that the keyboard is QWERTY, which can change them on international keyboards. For example, the "iddqd" cheat code would have to be typed as "iddad" on an AZERTY keyboard.

Each game has its own set of cheat codes, though the allcheats console variable allows to use them all in any game. For most purposes, the console offers more power and more versatility than cheats. Although DeHackEd allows to change the cheat codes, this feature is not supported in ZDoom.

The following cheat codes are supported in ZDoom:

Doom

idbehold	Displays the message "inVuln, Str, Inviso, Rad, Allmap, or Lite-amp", typing one additional letter gives a powerup: "v": Invulnerability sphere "s": Berserk "i": Blur sphere "r": Radiation-shielding suit "a": Computer area map "l": Light-amplification visor
idchoppers	Gives and select the chainsaw.
idclip	No clipping. Equivalent to typing "noclip" in the console. Contrarily to vanilla Doom, this cheat works in Doom/The Ultimate Doom even without allcheats on.
idclevxy	Warps to level ExMy or MAPxy. Equivalent to typing "idclev xy" in the console.
iddqd	Sets health to 100% (even if higher!) and makes player immune to damage. Equivalent to typing "iddqd" in the console.
iddt	This cheat needs to be typed in automap mode and cycles the value of the am_cheat console variable between 0 and 2. First use: full automap (including hidden linedefs normally not shown). Second use: full automap with all actors shown as vectorial triangles. ZDoom allows you to give different colors to the various thing types. Third use: the automap is restored to normal.
idfa	Equivalent to typing "give backpack; give weapons; give ammo; give armor" in the console.
idkfa	Equivalent to typing "give backpack; give weapons; give ammo; give keys; give armor" in the console.
idmusxy	Plays the music from level ExMy or MAPxy. Contrarily to vanilla Doom, the weapon slots are not triggered when typing this cheat.
idmypos	Shows the player's X, Y and Z coordinates. Contrarily to vanilla Doom, the coordinates are given in decimal numbers.
idspispopd	No clipping. Equivalent to typing "noclip" in the console. Contrarily to vanilla Doom, this cheat works in Doom II/Final Doom even without allcheats on.

Heretic

cockadoodledoo	Turns the player into a chicken. Equivalent to typing "morphme" in the console.
engagexy	Warps to level ExMy (or MAPxy). Same as the Doom cheat "idclev". Equivalent to typing "idclev xy" in the console.
gimmex	The code is followed by a letter (a-j or z) which defines which item is given: "a": Valador's Ring of Invunerability "b": Shadowsphere "c": Quartz Flask "d": Mystic Urn "e": Tyketto's Tome of Power "f": Torch "g": Delmintalintar's Time Bomb of the Ancients "h": Torpol's Morph Ovum "i": Inhilicon's Wings of Wrath "j": Darchala's Chaos Device "z": Equivalent to typing "give artifacts 16" in the console.
iddqd	Kills the player. Equivalent to typing "kill" in the console. If "allcheats" is on, the Doom cheat takes precedence.
idkfa	Takes all weapons except the wimpy weapons that use no ammunitions. If "allcheats" is on, the Doom cheat takes precedence.
kitty	No clipping. Equivalent to typing "noclip" in the console.
massacre	Kills all monsters on the current level, equivalent to typing "kill monsters" in the console.
noise	Toggles sound debug information. The display is different from vanilla Heretic.
ponce	Sets health to 100%, equivalent of typing "give health" in the console.
quicken	Makes the player immune to damage ("God mode"). Contrarily to the Doom cheat "iddqd", this does not change health.
rambo	Equivalent to typing "give backpack; give weapons; give ammo; give armor" in the console.
ravmap	This cheat needs to be typed in automap mode and cycles the value of the am_cheat console variable between 0 and 2. Same as the Doom cheat "iddt".
shazam	Gives the Tome of Power effect.
skel	Equivalent to typing "give keys" in the console.
ticker	Toggles ticks-per-frame counter, represented by tiny black pixels in the lower-left corner. (They are quite hard to notice on high resolutions.)

Note: The "ravpic" cheat from vanilla Heretic is not supported, since ZDoom offers a screenshot command which can be bound to its own key and does not need to hijack the info menu key instead.

Hexen

butcher	Kills all monsters on the current level, equivalent to typing "kill monsters" in the console. Same as the Heretic cheat "massacre".
casper	No clipping. Equivalent to typing "noclip" in the console.
clubmed	Sets health to 100%, equivalent of typing "give health" in the console.
conan	Takes all weapons except the wimpy weapons that use no ammunitions.

satan	Turns on god mode, equivalent to the Heretic cheat "quicken".
sherlock	Equivalent to typing "give puzzlepieces 25" in the console.
visitxy	Warps to level xy, using the value given to the level by the "warptrans" property in its map definition. Equivalent to typing "hxvisit xy" in the console. This is not the same as the "idclev" or "engage" cheats: for example, "idclev 24" in Hexen will send you to Effluvium, whereas "hxvisit 24" will send you to Dungeons.
where	Shows the player's X, Y and Z coordinates. Contrarily to vanilla Hexen, the coordinates are given in decimal numbers.

Note: Vanilla Hexen uses different cheats in the demo version, where the codes are derived from the names of the developers (e.g., bgokey for Ben Gokey corresponds to god mode). These cheat codes are not implemented in ZDoom.

Furthermore, the "init", "puke" and "shadowcaster" cheats have been disabled. "Puke" can be used as a console command instead; but "init" and "shadowcaster" were removed because of technical concerns. Other Hexen cheats not implemented include "~xy" to change the CD track number, "mrjones" to display version information, and "martekmartekmartek" to kill the player. Finally, "noise" and "ticker" are implemented as Heretic cheats and can be used in Hexen with "allcheats" on.

boomstix	Equivalent to typing "give backpack; give weapons; give ammo; give armor" in the console.
donnytrump	Gives a HealthTraining item, which itself also give money and a GunTraining item.

elvis	No clipping. Equivalent to typing "noclip" in the console.
gripper	Toggle the "no velocity" cheat on or off. When active, the player's horizontal velocity is lost after each tic, resulting in a snail's pace and in jumps that are purely vertical.
gps	Shows the player's X, Y and Z coordinates.
jimmy	Equivalent to typing "give keys" in the console.
lego	Each time entered, gives one piece of the Sigil. If the player has the full Sigil assembled, this cheat will also remove it.

pumpupx	Displays the message "Bzrk, Inviso, Mask, Health, Pack, Stats", typing one additional letter gives one or more items: "b": Berserk "i": PowerShadow "m": PowerMask "h": MedPatch, MedicalKit, SurgeryKit "p": AmmoSatchel "s": UpgradeAccuracy, UpgradeStamina "t": PowerTargeter
riftxy	Warps to level ExMy or MAPxy. Equivalent to typing "idclev xy" in the console.
