You probably don't want to hear this, but one way to unlock all the zombie maps in "Call of Duty: Black Ops" is to beat the game in regular mode. Of course, that takes a long time, and you probably had something a little faster in mind.

The other way is to use "Call of Duty: Black Ops" cheat codes to unlock the arcade mode of zombies or all the zombie mode maps.

Where to Enter the Cheat Code

Entering the code is the easy part, but, first, you have to navigate to the right place to do so. Here's how to find the place for entering the code on Xbox 360 and PlayStation 3:

  1. Press Start on the main screen when you first start up your game. You'll be in a room looking at a television set.

  2. Tap the L2 and R2 buttons on the PS3 (LT and RT on the Xbox 360) rapidly and repeatedly while you're sitting in your chair in this room. This action causes you to stand up.

  3. Walk forward and turn to the left.

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

  5. Activate the computer. A keyboard appears at the top right of the screen. You type your cheat code into this keyboard.

  6. Type DOA and press Enter to unlock the arcade mode of zombies, or type 3ARC UNLOCK and press Enter to unlock all the zombie mode maps. 

While you're there, you can temporarily unlock all intel in "Call of Duty: Black Ops" with the code 3ARC Intel, but this code disables some achievements.
