I am having the hardest time completing this. I am wearing the best body armor and full health. I easily kill the bikers in the van. When they try to ambush me, knowing the road, I either get killed trying to flee or one is killed with one shot, getting out of the van. I am trying to get her up to the Alturist site. How do I survive this? The Lost are usually easier to kill than Stormtroopers.
