No fighting in the war room… unless its being attacked by zombies! Treyarch has revealed the not so secret Zombie mode for COD Black Ops with a big Halloween surprise!

Former US president John F. Kennedy

Former US president Richard Nixon

Former US secretary of defense Robert McNamara

Cuban revolutionary and subsequent state leader Fidel Castro

All of these men are playable characters in the 4 player co-op zombie mode, fighting to save the pentagon on multiple floors, I did not see this coming. Some gameplay videos complete with in game quips after the jump;

Apologies if they get removed before you can watch them, still on the hunt for an embeddable opening cutscene.
