The classic shooter Wolfenstein 3D was released for DOS on May 5 1992, twenty years ago.
Developed by id Software the game seemingly put the FPS genre on the map, allowing players to run through corridors and shoot enemies in a first-person view. It was revolutionary at the time, and was only surpassed by id Software's next big release, DOOM.
To celebrate Wolfenstein's 20th anniversary Bethesda is launching a free-to-play version of the classic PC shooter that runs within a Web browser. All three episodes are intact: Episode 1: Escape from Wolfenstein, Episode 2: Operation: Eisenfaust, and Episode 3: Die, Fuhrer, Die!
