See...maybe I'm overreacting, but it seems that you're just making the average Peacekeeper squad so powerful that the resistance is pretty much doomed from the start. I know, they're supposed to be outmatched, but not to the point where they don't stand any chance at all.
Oh, c'mon, you actually gave the peacekeepers gas masks. How can you expect them to not be mooks?And I don't believe in "PCs and NPCs" for ABR. There is no DM to control almost all people in the world, each character is controlled by someone else. Even the suicidal and incredibly stupid drows that exist only to die at the hand of the main cast.
