Id Map01

id Map01, also known as IDMAP01.WAD, is a single-level deathmatch PWAD for Doom II, authored by American McGee. It is the only known level created by a then-employee of id Software to be released as a PWAD level, instead of being a direct part of one of the games, comprising part of an advertising deal (such as Tim Willits's Kick Attack! level), or having been created and released as fan works before the author actually became an id Software employee or after they left the company (as is the case with John Romero's Tech Gone Bad and Phobos Mission Control).

This level was incorporated in DWANGO1.WAD, and was also adapted by Raven Software to Heretic, initially as a hidden E4M1 only accessible through the DeathManager! utility or via command-line options, and was later moved to E6M3 for the Shadow of the Serpent Riders expansion.

Trivia
IDMAP01 gained some additional note, including mentions in game industry press, in mid- when it was brought up by former members of id Software as part of their refutation of Tim Willits' claim of having invented the concept of deathmatch-only maps in first-person shooter games.
