Regret - Skull (Assassins) For the skull you’ll fight through Regret until you cross the first gondola ride. Using Sputnik skull, grenade-jump up onto the roof of this building, then follow the roofline to the right and around to the back of the building, where you’ll see two invisible Elites dancing with swords below. The skull sits between them. Check the video in the notes section starting at
10:26 for this one.
