Skull (Catch) For the skull on this level, you will reach a wide open outdoor area with tons of Jackal snipers with Beam Rifles and a few Elites. This is the area that you reach at the end of the tunnel where you do the Banshee trick above. If you reach the next large area with the Wraith and a tunnel leading to a waterfall beyond it, you went too far. In the Jackal sniper area, after clearing them out, look for the narrow, large arch in the middle of the area. Go to the bottom of it and jump up onto it, walking up to the very top. When you reach the T-intersection at the top, hang a left and another left, hugging the ledge around to the skull. Refer to the video once more, this time at the 04:26
mark for this one.
