Also for people who don't know yet, hit the trigger buttons at the main screen. You can get out of the chair. Then go to the computer and type DOA, the PC will unlock Dead Ops Mode, you can later access it on the main menu screen via Zombie. Dead Ops is a retro top down game, you play it using your dual stick shooter, it even has Co-op Mode! You can unlock further achievements/trophies when playing the mode.“Can we type anything else?” I will give you another one, Typing ZORK will unlock the text based adventure game.
