Two new maps, DOA and Five, are now available on Xbox 360, PS3, and PC for your Black Ops zombie-killing pleasure. According to the press release:

"DOA, or Dead Ops Arcade puts you and up to three other soldiers in a pursuit of the Cosmic Silverback; tracking him through a gauntlet of arenas filled with traps, treasure and waves of flesh-hungry zombies.

Five features four significant real-life figures from the Cold War era: John F. Kennedy, Robert McNamara, Fidel Castrol and Richard Nixon. They are all meeting in the Pentagon when zombies break in and start attacking."
