Ok so I've done just about everything I can to make this skull appear, but on every difficulty, no matter if I start from the beginning of the game, or Mission start on The Ark, this skull isn't there. Has anyone else seen/heard of this. Its driving me insane hahDawnofthefalll 20:24, May 20, 2012 (UTC)
