What do an American GI, a Nazi, a Russkie, and a Jap have in common? I’m glad you asked! From the Nazi Zombies Wiki:

Zombies, originally known as Nazi Zombies, is a Treyarch exclusive game mode that first appeared in Call of Duty: World at War. It became highly popular upon the game’s release, and returned in its sequel, Call of Duty: Black Ops, and again in Call of Duty: Black Ops II.
In Zombies, players face endless waves of zombies, buy weapons and perks, and repair nearby defenses to keep zombies out. Zombies become stronger and faster upon completion of each round, forcing players to make tactical decisions about point spending and progressing through the map. Both single player and co-op survival modes are available with up to four players online or two players in local split-screen.
