Halo 3's last known Easter Egg has been found, a cool seven years after the game was released.

According to intrepid Halo explorers at Teambeyond.net , if you press down on both thumbsticks during the loading screen on December 25, you'll be shown a wider view of the Halo ring. If you look closely - and I mean, really closely - you'll see the words “Happy Birthday Lauren!” spelled out on the ring's surface.Bungie has teased players with the final Easter Egg for years. In a Q & A in a Bungie Mail Sack from 2012, Jon Cable said “there is one Easter egg in Halo 3 that I don’t think anyone has found – I stumbled across it in code a while back. It only happens on a specific day … so good luck.”In a subsequent mail sack (with an expired link, text is preserved here ), Adrian Perez claimed his proudest moment at Bungie was "showing my wife the Easter egg I put in the halo 3 loading screen for her - the one that nobody has found yet."And now they have. Happy birthday Lauren! Check out the video of the discovery below.
