Locate Terminal
Before you enter any cheat codes in Black Ops Zombies, you must first break free of the chair that you're locked to. Press the left and right triggers on your XBox controller repeatedly to escape the chair, then walk to the computer located behind the chair and press the "A" button to access the computer terminal's command prompt.
Intel Information
Type "3ARC INTEL" into the computer terminal to unlock the intelligence or "Intel" information associated with Black Ops Zombies missions. The unlocked Intel information provides you with details on the game's conspiracy theory that is not otherwise provided during gameplay unless you locate Intel black boxes in each mission. There's one caveat to using this cheat: once you've executed the terminal command you are no longer eligible to receive the XBox 360 "Closer Analysis" trophy that you receive after unlocking all Intel information in the game.
Minigames
You can use three terminal commands to unlock and play Black Ops Zombies minigames. You can type "ALICIA" at the prompt to play the Alicia the Therapist minigame or you can type in "DOA" to play the Dead Ops Arcade minigame. Type in either "ZORK" or "HELLO SAILOR" to play the Zork text-based minigame; if you play this game then you will also receive a special XBox 360 trophy.
3ARC Unlock
Black Ops Zombies includes a single powerful command that you can use to unlock several locked features. If you type "3ARC UNLOCK" at the command prompt then you will unlock the Zork and Dead Ops minigames, the "Five" Zombies mode map and all Black Ops Zombies missions.
