Cheats are available in Call of Duty: Finest Hour, Call of Duty 4: Modern Warfare, Call of Duty: World at War, Call of Duty: Modern Warfare Remastered, and Call of Duty: Modern Warfare 2 Campaign Remastered.

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 ZORK into the computer will unlock the trophy/achievement Eaten by a Grue as well as start up the text-based adventure game Zork.
Typing in DOA will unlock Dead Ops Arcade.
Typing ALICIA will start a virtual interactive therapist.
