Me and my neighbor got all of the skulls except for the IWHBYD(I WOULD HAVE BEEN YOUR DADDY) skull and we know how to do it but its at the end of the level and ive heard you have to beat the game before you do it....i have beat the game.but with his profile he hasnt. We are playing on the same console..if i do the rings and everything will the skull still pop up?? cuz i dont want to go altheway through the level just to find out if we BOTH had to have beat the campaign!
