Had that earlier. Jeep smashing through trees, with two guys shooting at me and another bad guy jeep on my hammer. Was simpler to go back to the previous checkpoint.
The one that sucks is climbing out of the ship with a bunch of guys and a helicopter shooting at you, eventually picking them all off with only a teensy bit of health left, walking off the ship onto the raft below - only to clear it and fall into the water. Then sprint around to get back onto the ship, forgetting I'd used all my stamina sprinting so the instant I go underwater, I drown.
