Looking around the forum, seems like theres only one other guy who even managed to start the easter egg while the rest of you were comparing what rounds you finished the map on. Anyways to start the easter egg, 1) Shoot the tomb near the lava pit (it is outside of the map) a green halo should appear and the "hide and seek " phase should begin. 2)Shoot statues around the map statue #1 is the gargoyle on the church statue #2 is the lion on top of the gravehouse in the starting area of the map statue #3 is the gargoyle on one of the inner tombs where PaP is. Once done, you should get a notification telling you that youre done, collect the wunderwaffe from inside the shed and thats the easter egg done
