‘Wolfenstein 3D’ available to play for free in browser for game’s anniversary

It's been 20 years since the Nazi-killing first-person shooter was released, and Bethesda Software is celebrating by bringing the game to browsers — for free.

For those unfamiliar with the game, Wolfenstein 3D is one of the earliest first-person shooters, based on the game Castle Wolfenstein from 1981 for the Apple II. The premise of the game is simple: take your gun and kill Nazis in order to escape Castle Wolfenstein during WWII. According to TIME, Wolfenstein 3D was a pioneer in 3D effects, showing enemies from eight different angles instead of just a head-on view, which was the norm for prior computer games.

The game was originally published by Apogee Software as free shareware and was a precursor to the iconic 1993 release Doom FPS, also developed by Carmack.

If the free browser experience isn't enough to satisfy your Wolfenstein cravings, you can also buy discounted bundles on the Steam game service to play some of the other titles, including Spear of Destiny and Return to Castle Wolfenstein. Wolfenstein 3D is also available for free for iOS on iTunes for a limited time.
