Your character will be in a room looking at a television set. 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. Walk forward and turn to the left. Move along the wall until you arrive at a computer. Interact with the computer to make a keyboard appear at the top right of the screen. Type 3ARC UNLOCK and press Enter to unlock all Zombie Mode maps. Use the computer to enter additional cheat codes.
