Sometimes developers leave a few clues to let players know when an Easter Egg or secret is near. A hollow sounding wall or maybe a trail of coins, but its not often that there are hidden things to find within the games menu screen. How To Find It When you're restrained (and able to look around), break free by pulling the left and right triggers back and forth and wander around the interrogation room. Then walk up to the old-school computer terminal and type in the word ZORK and experience the very early video game of the same name. Zork was originally released in 1977 and while its text-based gameplay might not necessarily appeal to the average CoD player, or indeed modern video game fan, it was ground-breaking in its day. If you prefer your games to be a little more action-packed, typing DOA into the terminal will let you play Dead Ops Arcade, a top-down blast-a-thon where ammo is unlimited and players are tasked with surviving as long as possible against wave after wave of zombies. So whether its text-based adventure or gung-ho action, CoDs hidden games have you covered.
