In 1992 many of us had the pleasure of playing id Software's incredible first person shooter ' Wolfenstein 3D ' for MS-DOS. It was the second major release after Commander Keen and featured a unique 3D game engine with multiple enemy types such as Nazi soldiers and dogs, and multiple weapon types to defend yourself with such as guns and knifes. It is a game that is still loved to this day and as a love letter to Wolfenstein 3D, Vaultkeeper has released the full standalone version of Atomprojekt.
