Instructions
Insert "Call of Duty: Black Ops" into the Nintendo Wii console. Press "A" to load the game and go to the main menu.
Press down on the analog stick when the main menu appears. You see Alex Mason's wrists strapped to a chair.
Tap "ZL" and "ZR" together repeatedly if you are using a Wii Classic Controller. The straps break and Alex is free. Alternatively, shake the Wii Remote and Nunchuk to break the straps.
Turn around and walk behind the chair. Approach the computer terminal and press "A." A flashing cursor appears on the screen.
Enter a cheat code. For example, the code "3ARC UNLOCK" unlocks every mission. "ZORK" unlocks a hidden minigame.
