This works only in Doom and The Ultimate Doom (see above for the equivalent idclip for Doom II). 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. Shows the player's coordinates and compass direction (note that these numbers are hexadecimal, and may require some practice to interpret quickly). Using this cheat code will make the player change weapons in hand if the numbers pressed correspond to available weapons. Plays music from level MAP # in Doom II or Doom, and E #M # in The Ultimate Doom. Grants full megaarmor protection (200%), all weapons, full ammo, and all the keys.

This is the same as idkfa below, but excludes the keys. Third use: the automap is restored to normal.Second use: full automap with items, monsters, players, obstacles, and decorations.First use: full automap (reveals unexplored areas, including invisible linedefs not shown by the computer area map powerup).This cheat reveals information if used while in automap mode, showing additional data the second time it is used: 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. If the player is currently standing on or subsequently enters a damaging floor of type 11, the invulnerability effect is nullified. Sets health to 100% and makes player immune to damage ("god mode", "degreelessness"). This may have certain side effects (see IDCLEV idiosyncrasies). Some source ports require this cheat code instead of idspispopd. Identical to idspispopd, except that it is for all other Doom games. Gives the option to select the chainsaw and 1 tick of invulnerability

When # is one of the letters below, this gives the powers of an item:
