They made it in a building they called “Suite 666” because id Software was founded and run by turbo nerds. The game was central to the development of the concept of first person shooters, showing a twitchy speed not seen in first person games to that point, and then one year later they defined the genre in its most basic foundations with Doom, a game that was installed on more PCs than Windows at the time. In 1992, id Software used John Carmack’s new rendering technology to release the action packed Wolfenstein 3D.
Note: Screenshots, unless stated otherwise, come from The Ultimate Doom re-release by Nerve Software for PC, which does tweak the graphical fidelity of the original game, but otherwise remains faithful to the original style.
