Well... only a hidden heaping of nudity, public indecency, love letters, coded symbols, mysterious music, creepy characters, pop culture references (Mario? Seinfeld?) and other inside jokes - some hilarious, some plain bizarre - left behind by the game's sneaky creators.
Don't believe us? See for yourself on the following pages. We show you everything we and the Halo 3 community have found so far, plus how to locate them in your own game. Okay then - let's hunt some Egg!
We'll start with three of the toughest eggs. These are so difficult to recreate, in fact, that we've left it to the fan community to demonstrate them for you.
EASTER EGG #1 - Actual Easter Egg
A shimmering sphere of mysterious numbers hidden high, high, high above the multiplayer desert of Sandtrap. A coded map to secret treasure, or simply some forgotten programming? For a closer look, you'll need to use a tricky combination of Forge, Theater, teleporters and sentinels to push yourself through the map's locked barrier.
EASTER EGG #2 - "How did you do that?"
Halo 3's creators know how to reward the hard work - and the inspired madness - of their fans. So if you manage to overturn the largest vehicle in the game with a little luck and a whole lot of explosives, you'll receive some humorously impressed feedback.
EASTER EGG #3 - Super Mario Scream
Nintendo's mascot in Microsoft's mascot's adventure? The mind reels. But watch - no, listen - to these three pieces of evidence. Sounds to us like the distinctive death of the world's most distinctive plumber. "Yawwwwhoooohoooohooooo!"
