Call of Duty: Black Ops – Hidden Mini Games
When players of “Call of Duty: Black Ops” discovered the game’s opening menu featured their character strapped into a chair, few thought to actually attempt to escape. When some finally did, they were able to stumble over to a computer terminal and try their hands at random commands. Not only does the command “DOA” load a top-down zombie shooter called Dead Ops Arcade, but typing in “Zork” reveals that the developers actually included the 1977 text adventure in its entirety. They apparently had some free time on their hands.
