If you do not already know Call of Duty: Black Ops has a special game mode for your enjoyment. This game mode is called Dead Ops Arcade and it is unlocked right in the main menu. I will give you a step-by-step procedure on how to unlock this unique arcade style game mode.
Now once you have arrived to the Black Ops main menu (after you have pressed start) you will see a T.V screen with your basic options: Campaign, Multiplayer, Zombies, and Options. Once you are on this screen you can look down and see that you are strapped into a chair if you are playing for Xbox 360 press Lt and Rt or for PlayStation 3 L2 and R2 until your player breaks out of the chair, your quest is still not over you have to go to the back of the room and use the computer which is directly behind where you were sitting you may have to maneuver to actually get to it. Now once you are on the computer a keyboard will appear on the top right corner of your screen type in DOA and you will be brought to the Dead Ops Arcade screen immediately. If you were wondering if you have to do this every time you want to play it you don’t, after you have done this once it will be accessible from the Zombies option on the main menu.
