idbeholdv	1.00	Gives you invulneratility.
idchoppers	1.00	Gives you a chainsaw. Find some meat!
idclev**	1.00	Jump to level *. On Ultimate Doom, the first is the episode number, and the second * is the level number (1-9). On Doom II, is a number from 01-32. Note:** this code resets your status to 100% health, 0% armour, a pistol and 50 bullets. All other weapons and ammunition are removed, along with backpack.
idclip	1.00	Toggle clipping mode (allows you to walk through walls and other objects). Note: this disables your ability to use teleporters and pick up objects. Only works on Doom II, use idspispopd on Ultimate Doom.
iddqd	1.00	Toggle 'god mode'. When on, health changes to 100%, and you can't be injured. Well almost. If you are on a teleport pad and another human player or monster (except on Doom II, level 30) teleports to where you are then you die.
iddt	1.00	Toggle automap mode: First time: Show all map detail Shows the whole map, and all walls, doors, trigger lines etc. Second time: Map details and objects Shows the whole map, and all objects including monsters and projectiles are indicated by green triangles. Third time: back to normal.
	2.00	Same as above except: Third time: toggles new details mode Star for collectables, red hexagons for dead monsters, brown hexagons for some objects, and brown triangles for monsters. Coloured keys and doors are also shown. Fourth time: return to normal Note: this code must be entered while in automap mode (press TAB), if you've got Doom+, PIP map doesn't count :-).
idfa	1.00	All weapons, full ammunition and 200% armour. Note: your ammunition-carrying capacity doubles when you pick up your first backpack.
idkeya	1.00	Gives you all the keys.
idkey*	2.01	Gives you key * (where * is the first letter of the key colour - r, y or b).
idkfa	1.00	All weapons, full ammunution, 200% armour and all keys.
idmus**	1.00	Use music track from level ** (obviously this only works if you can hear the music anyway). 33 plays the interlude music (the music that is played when you complete levels 6 and 11), 34 gives plays the title screen music, 35 gives the interlude music for every level apart fom 6 and 11.
idmypos	1.00	Display your angle and coordinates in hexadecimal format.
idspispopd	2.00	Same as idclip except this one works on Ultimate Doom. It stands for 'Smashing Pumpkins Into Small Pieces Of Putrid Debris'.
idspread	2.00	Toggle 'Plasma Gun Spread Mode', where one shot of the plasma gun actually fires 9 bolts in a spread in front of you. This makes the plasma gun more effective for clearing rooms than the BFG (but makes you loose ammo pretty quick).
	2.02	As of v2.02 this cheat increments the number of bolts that the plasma gun fires in 'Plasma Gun Spread Mode'. The sequence of this is 3, 5, 7, 9 and OFF.
idtrans	2.00	Toggle transparency.
idfight	2.01	Allow monsters to fight one another.
idmuscd	2.01	Display CD name (if !CDDB in use) or number (if not).

idpack	2.01	Gives you a backpack.
idcache	2.02	Toggle the column caching.
idresamp	2.02	Change the resampling level.

Note: all cheat codes except idclev** and iddt are disabled on Nightmare skill level, and many are disabled when playing network games.
