The tradition of the Easter Egg hunt where children search for decorated or candy eggs hidden throughout the house or garden has long ago made the leap from meatspace to cyberspace, with many game developers working in little "Easter Eggs" throughout their works. These include allusions to pop culture, favorite works, previews of future games, and running gags across entire series. Here are a few of our favorites, and feel free to add your own in the comments section below!
Two years before the release of Arkham City, developer Rocksteady snuck a tease of its premise into Batman: Arkham Asylum. Head to Quincy Sharp’s office in Arkham Mansion. Just to the right is a wall that can’t be spotted with detective vision, but can be blown with explosive gel. Your reward? Blueprints for the eponymous city prison.
In the "Critical Mass" mission of this classic nineties shooter, is a pretty obvious reference to the classic animated sitcom 'The Simpsons.' Just hit the action button against one of the walls to open up a room that features Homer’s workstation from the Springfield Nuclear Power Plant. Who wants donuts?
The finale to classic FPSDoom II opens with a creepy arcane chant that is actually a back-masked and distorted clip of series co-creator John Romero saying, "To win the game, you must kill me—John Romero." True enough, you can use the idclip cheat to walk through the wall to see that behind the Icon of Sin is John Romero's severed head on a stick.
The very nature of open world games means that there are literally hundreds of Easter eggs littered in the most obscure corners. However, one of the Easter eggs in this game, located on a bridge that connects San Fierro to Las Venturas, is a sign that says, "There are no Easter Eggs up here. Go away."
The developers at LucasArts managed to sneak in a full-length game in this wacky animated comedy adventure. Okay, it’s really just Maniac Mansion, which is Day of the Tentacle’s predecessor from the wild Commodore 64days. Just head on up to Weird Ed’s room and you can use his computer to play this classic in its entirety.
This Atari 2600 title featured what is arguably the first video game Easter egg. Because credits in video games were not standard practice then, Adventure’s creator smuggled his name into the game itself. If you bounce your cursor to grab an invisible gray pixel and bring it to a corridor below the golden castle, you are taken to a room that simply says, "Created by Warren Robinett."
Rumors persisted of a secret cow level in the original Diablo. Four years later, Blizzard paid tribute to these false rumors with an actual cow level. After completing the game, head back to the rogue encampment and use the Horadric Cube to transmute Wirt's Leg and a single Town Portal! Enter to face an infernal horde of bovine.
