Call of Duty: Black Ops Easter Egg - Secret Terminal

When you get to the menu screen, move the right stick around. You will find that you are in control of a character in a chair. Mash the triggers and he will break out of the chair and you can walk around. In the back of the room there is a terminal that you can hold x (xbox 360 controller) to access, thus bringing up an on-screen keyboard. You will be given some commands that you can use, but the real secrets are not shown. Type in the command "DOA" and hit enter to play a smash tv style arcade game. Try the same with the command "zork."
