When people think of id Software they usually think of the Doom series. However, Doom wasn't their first big hit. The year before Doom took the world by storm, id released Wolfenstein 3D.
Wolfenstein 3D was originally released for DOS based PCs but was ultimately ported to a wide variety of platforms. The original was released in 1992 and was inspired by a much older game, Castle Wolfenstein, which was originally released in 1981. In Wolfenstein 3D you play the role of a spy attempting to defeat the Nazis. Like Doom that followed it, the game consists of a number of episodes, the first of which was released as shareware.

In 1994, ports were released on the Super Nintendo, Macintosh, and Atari Jaguar. In 1998 there was even a port for the Apple IIgs. Later ports include the Game Boy Advance, Xbox Live Arcade, PlayStation NEtwork and an iOS port by John Carmack in 2009.
Wolfenstein 3D never quite gained the fame of Doom for a few reasons. By the time the ports came along, Doom was already out and even the original release was was only a year or so ahead of Doom. While Wolfenstein 3D was an excellent game in its own right, Doom made a number of significant advancements with its entirely new 3D game engine, not to mention the online Deathmatch capability. However, first person shooter fans should definitely check out this game, preferably the original PC version.
