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 on 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 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.

First, you have to get to the right place to enter it. Here's how to do that on Xbox 360 and PlayStation 3:

  1. When you first start up your game, you press Start at the main screen. You will be in a room looking at a television set.
  2. While you are sitting in your chair in this room tap the L2 and R2 buttons on the PS3 (LT and RT on the Xbox 360) rapidly and repeatedly. 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. This is where you type your cheat code.
  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 are there you can unlock all intel with the code 3ARC Intel, but this code this disables some achievements.
