Unlock All Zombie Mode Maps and More in Call of Duty: Black Ops Cheats

One way to unlock all the Zombie Mode maps in Call of Duty: Black Ops is to beat the game. That said, if you want to access them right away Call of Duty: Black Ops has cheat codes that unlock all Zombie Mode maps and additional content from the very beginning.

How to Unlock Zombie Mode Maps

To enter the code that unlocks all maps in Zombie Mode:

1. Press Start on the main screen when you first start up the game. Your character will be in a room looking at a television set.

2. Tap the L2 and R2 buttons on the PS3 (or LT and RT on the Xbox 360) rapidly and repeatedly to stand up.

   If playing the PC version, hold the Space bar. On the Wii, shake the controller.

3. Walk forward and turn to the left.

4. Move along the wall until you arrive at a computer.

5. Interact with the computer to make a keyboard appear at the top right of the screen.

6. Type 3ARC UNLOCK and press Enter to unlock all Zombie Mode maps. 

Use the computer to enter additional cheat codes. For example, enter DOA to unlock a mini-game called Dead Ops Arcade, or enter 3ARC Intel to temporarily unlock all intel.
