with the cowbell, it works to have two people and two gravlifts; drop one, then the other on top of it and it puts you at the right height to get the skull.

you have to play all levels from the start to get the skulls, and terminals; if you play through the whole game and get all the terminals it gives you a special messsage on the last one. i think it must be done on legendary though. you have to play through in one sitting, so go in alone and play the 2 hours on easy or 8 on legendary campaign; or splitscreen/systemlink works too.

one more thing, there is a terminal in the bridge room on Cortana where the skull is, its below the central platform, theres swords, cloak, and some other weapons too.
