Pistoleer Archive

Honestly, I'm finding myself killing the same old things, avoiding the same old things as I progress up Pistoleer. So I wanted to see if maybe I'm just not taking advantage of all my skills. Currently a 0,1,1,0 (almost have 1, 1, 1, 1), but I'd like to know if I could ever beat a Stormtrooper in a straight up fight. If so, what do you use? What skills do you suggest? So far, I've been sticking with Health/Body/Warning shot as they kill critters fairly well.

Any insight into this? Thanks!
