This cheat reveals information if used while in automap mode, showing additional data the second time it is used: The invulnerable player can still be killed by a telefrag, a spawn cube in MAP30, or any modified enemy projectiles with extremely high damage ratings (such as from a DeHackEd modification).

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 any damage source dealing less than 1000 damage ('god mode', 'degreelessness'). This may have certain side effects (see IDCLEV idiosyncrasies). No clipping in Doom II (see idspispopd below for technical details). When final letter is typed: 'Power-up Toggled' When 'idbehold' typed: 'inVuln, Str, Inviso, Rad, Allmap, or Lite-amp'

If you already have one of those power-ups in any way same power-up will be toggled off (with the exception of the Computer area map). When # is one of the letters below, this gives the player the chosen power-up:
