Not sure if anyone else posted this but, if you go to the "Statue's" area and shoot the books in the hands of each of the Statues their faces will catch on fire and Dom will scream every time, and once you get them all on fine the sun behind the northern most statue will have Dom"s beard. Tested it on Horde mode and worked, i doubt it will work on any other game mode. The statues themselves"s also had Dom"s Beard.
