To unlock all zombie maps on Black Ops, simply break out of your chair (back buttons on controller) and head to the small computer again. Instead of inputting DOA, type in the following sequence ’3ARC UNLOCK’ (with a space in between). If you have done it correctly, you should see a message saying the cheat has been activated pop up on screen.
Head back to your chair and start up a zombie game, you’ll now see that all maps have been unlocked straight away
