Anyone else notice that the last area where you fight Crota himself is a picture of his face. For all you platformers that can get up the tower (left boomer tower) to the extreme high points, climb up there and look down. You can distinctly see his three eyes and where Crota stands is his mouth. The two large horns to each side of Crota is actually the bottom of his mouth/chin. The two areas that Crota moves to are his two lower eyes and the crystal room is his third upper eye. Kinda cool. Just thought I would share it.
