I'm trying to get the catch skull and i know exactly where it is but i can't get there because of the wraith that always blows up the warthog or ghosts. Also none of my Live friends are on when I'm on so I can't do co op with them to get the skull. I've tried everything else though (or so i think). If anyone would help that would be great.
