Here’s how to unlock Dead Ops Arcade in “Call of Duty: Black Ops” for the Xbox 360, Playstation 3, PC, and Nintendo Wii.

Description: Unlock Dead Ops Arcade (Zombies Map)
Entry Location: Interrogation Room

After Breaking free from the restraints in the Interrogation room, head to the back of the room and find the interactive computer terminal in the corner. Access it, then enter “DOA” at the prompt to unlock Dead Ops Arcade, a retro top-down, two-stick shooter reminiscent of Smash TV and brimming with old-school zombies and rabid monkeys. You can now play this mode anytime – solo or co-op – by looking under the Zombies menu.
