Ultimate Doom Cheat Codes

This is a guide for the Ultimate Doom. I will list the cheat codes and tell you what they do. Note that these cheats do not work on the nightmare difficulty. I did not make this guide. I got all info from the doom wikia. So thank the doom wikia, not me! I only put it on steam so that it is easier for people to look at. I hope you enjoy, now go kill some Imps!

The Cheats!

idbehold# When # is one of the letters below, this gives the powers of an item: ◾ "R": Radiation shielding suit.
◾ "I": Partial invisibility.
◾ "V": Invulnerability.
◾ "A": Computer area map.
◾ "L": Light amplification visor.
◾ "S": Berserk.

idchoppers1 Gives the option to select the chainsaw.

idclip No clipping in Doom II and the iPhone version of Doom (see idspispopd below for technical details).

idclev##2 Warps to level E#M# or MAP##. This may have certain side effects (see IDCLEV idiosyncrasies).

iddqd3 or idqd Sets health to 100% and makes player immune to damage ("god mode", "degreelessness"). If the player is currently standing on or subsequently enters a damaging floor of type 11, the invulnerability effect is nullified. The invulnerable player can also be killed by a telefrag, and projectiles with extremely high damage ratings (such as from a DeHackEd modification) can also kill a player in god mode.4

iddt5 This cheat reveals information if used while in automap mode, showing additional data the second time it is used: ◾ First use: full automap (reveals unexplored areas, including invisible linedefs not shown by the computer area map powerup).
◾ Second use: full automap with items, monsters, players, obstacles, and decorations.

◾ Third use: the automap is restored to normal.

idfa6 This is the same as idkfa below, but excludes the keys.

idkfa7 Grants full megaarmor protection (200%), all weapons, full ammo, and all the keys.

idmus##8 Plays music from level MAP## in Doom II or Doom, and E#M# in The Ultimate Doom. Using this cheat code will make the player change weapons in hand if the numbers pressed correspond to available weapons.

idmypos9 Shows the player's coordinates and compass direction (note that these numbers are hexadecimal, and may require some practice to interpret quickly).

idspispopd10 No clipping (the player can walk through walls, monsters, and obstacles, climb high ledges instantly, and pass through items and across all tagged linedefs with no effect. This works only in Doom and The Ultimate Doom (see above for the equivalent idclip for Doom II).
