Make your way through the levels killing nazis as you go. This is a flash version of the classic game by id Software.
This appears to be an emulation of the exact game created by id software. Similar to DOOM or Quake, its a first person shooter where you are challanged to kill nazis. Make your way through the levels picking up health, guns, ammo, and treasure. Its a bit blurry compared to the computer version, perhaps to speed it up to make it browser compatible.
