Just like filmmakers, video game designers sometimes hide little jokes in their games, called Easter eggs.
Sometimes it's a secret room. Sometimes it's a whole playable level. Sometimes it's a secret message.
The first Easter egg appeared in a video game called "Adventure," which was released in 1979 for the Atari 2600 console. The game's author was annoyed he didn't get credit for his work, so he buried the text "Created by Warren Robinett" in a room so deep in the game, it wasn't found until a year later.
Since then, there have been hundreds of Easter eggs hidden in video games. And we've scoured the web to bring some of the coolest ones to light. (We've tried not to include any spoilers, but if you haven't played some of the games mentioned, read at your own risk.)
In "Batman Arkham Asylum," there's a hidden room off Quincy Sharp's office that you need explosive foam to find. But once you do, you'll be rewarded with a map of "Arkham City," which happens to be "Asylum's" sequel.
If you fulfill a super hard set of criteria in the Atari 400 and 800 port of "Donkey Kong," you'll get to see the coder's initials, LMD, on the start screen. The coder himself describes it as "totally not worth it," but someone took the time to find it.
Sports games even get in on the Easter egg action. In "NBA Jam," you can unlock certain political figures by pressing the buttons on your controller in a specific order. Democrats vs. Republicans like you've never seen them before.
