There is one Skull in firefight on crater. All you need to do is get hit by the gravity Hammer guy but dont die and land ontop of the building Farthest to the left of were you spawn.It will be laying on top of the airvent that is painted red. Ounce you get it you are invincible for one set. It really works try it.
