"From behind with a rocket launcher." Yeah, that would have been handy to know before tangling with the Predators, but I didn't have a rocket launcher anyway, and it turns up a couple of rifle shots from behind work just as well. Creepy bastards - dumb, but creepy, and their firepower's no joke.
Next couple of stops will probably require a squad, or at least a fireteam. I'm not much for playing nice with others, but I suppose I'll survive.
