Dead Ops Arcade
The Dead ops arcade is an Arcade version of "Zombies". The view is third-person and is in a bird's perspective. To unlock Dead Ops, go to the Main Menu and Press RT and LT at the same time a few times until Alex Mason gets out of the chair. Now, head over to the computer that is behind the chair that you just got up from. Hold X until a screen pops up and enter the code "doa". Congratulations, you just unlocked Dead ops Arcade!
