Once save is loaded select continue career, goto Exploration,
scroll all the way to the last one “The Geyser Field” and start event. For the last skull location please visit the link i’ve included to a youtube video which shows the location of the last skull at the 3:00 min mark. It’s really simple to get, all you need to do is jump a gap. Once you get the skull you have to press Start and then Exit Game.
