Yeah, the whole point of Predator is that the military-grade weapons and all of the testosterone-fueled machismo in the world didn't matter; it was a game of wits in the end. The Predator in this could be armed to the teeth with a plasma cannon and everything and still lose here and I would buy that. The main character is going to have to go through some real shit to get there, but so did Arnold, and the lead pulling off a win by using her environmental resources to her advantage is fully believable to me based on what we've seen before in this series.
