Call of Duty: Black Ops getting unlocked for President's Day Weekend
Starting now, two levels are being unlocked for the Xbox 360, PS3 and PC versions of Call of Duty: Black Ops, Activision announced. 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.
