10 Classic Video Games Hidden In Other Games As Easter Eggs

4. Zork In Call Of Duty: Black Ops

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 it€™s not often that there are hidden things to find within the game€™s 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 €œZORK€ 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 €œDOA€ 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 it€™s text-based adventure or gung-ho action, CoD€™s hidden games have you covered.
