I been playing the map since 5 am and me and my buddies have an idea of what the easter egg is. In the spawn room, in the Revive area there is a spinning totem pole that spins. You have to hold X on the 3 panels on the walls and someone has to step on a platform. Next room, if you look straight at the revive go to the room on the left for 750. There are panels on the walls with symbols. you have to put them in a specific combination. Note that you have to turn on the power first. Leave a response to let everyone know how to solve the easter egg or ideas you got so far in the game, thx :D
