Jon Cable; Bungie Employee Wrote:Definitely the IWHBYD skull in H3. But you cheated. 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.

It was believed that all of the easter eggs have been found a long time ago, until fans heard about this.
