...yes it does
In addition to me actually playing it, I don't know why I have to copy paste from Wikipedia.
quote:
The minigame Nacht der Untoten (German for "Night of the Undead") consists of 1–4 players fighting an unlimited number of waves of Nazi zombies. Players can work together with other people to kill the zombies known as "co-op" mode either offline with two players or online with 2-4 players. The players gain points by injuring or killing the zombies or repairing boarded-up windows, which are used to remove blockages inside the bunker and to gain access to more useful weapons than the starting pistol and unlock more rooms. Zombies continually break the windows to gain entrance and to find and kill the players; when all players die the game is over
