id unofficially started in September of 1990 when John Carmack, Adrian Carmack, John Romero, and Tom Hall created the first game in the Commander Keen series, Invasion of the Vorticons. One month after Commander Keen was released into shareware, John Carmack, Adrian Carmack, and John Romero left their jobs at Softdisk Publishing and officially began id Software, on February 1, 1991.

As a renown leader in the industry and one of the world’s leading developer, id Software has forged frenetic titles such as Wolfenstein 3-D, DOOM, DOOM II, QUAKE, and QUAKE II.

Named for the instinctual part of the human psyche first identified by Freud, id’s software development team continues to shape the future of gaming.
