That reminds me, When I was leading Prophet to the first heat source and the cutscene kicked in, he had 40% left. When the cutscene ended he had 1% and died instantly
Loaded my last save, and that didn't happen again.
When you are taking the island back (killing the AA for the aircraft) I went inside those huts with the mounted machine guns in the center of the island. If the roof falls on you (its only a 5 feet off the ground) you die instantly. I got stuck inside it once, and it grazed my guy and he died. This happened 3 times (I tested it).
Vehicle controls in general go to hell if you touch anything physics based. I've had my jeep launch into the air while trying to leave from a parked position while ontop of sheet metal.
