Call of Duty: Black OpsEdit
Typing 3ARC UNLOCK into the computer console accessible after breaking out of the chair will unlock all the campaign missions even if they are unplayed, Dead Ops Arcade, and Five (does work on the Wii, but only with Campaign missions, as the Wii only has one zombie map.). Doing this will, however, prevent story related achievements/trophies from being obtained.
Typing 3ARC INTEL into the computer will unlock all intel, but be warned, it will disable the achievement/trophy for finding them without cheating, making it impossible to get a platinum trophy on PS3 except by restarting the game.
Typing in DOA will unlock Dead Ops Arcade.
Typing ALICIA will start a virtual interactive therapist.
Typing 3ARC TROPHY will unlock everything in multiplayer, but will not increase the player's rank, and making it impossible to rank up.
