The objective of the game is to survive each round of invading zombies after which a more difficult round begins. SS soldiers who have become zombies attempt to infiltrate the bunker and attack the players, and the players must defend themselves in the process. The game's setting originally takes place in a German bunker (Nacht der Untoten) during World War II from the viewpoint of a US Marine.
