Gonna need to think. Guess it's pretty obvious that these guys are optimized for melee combat. Spikes, claws, can burp out smoke to try to sneak closer? Can climb walls, some maybe can glide. Leaders are obviously smarter than the regular goon-types, probably have some kind of "rallying cry" ability to bolster aggression. The ones who are smart enough to try to use weapons will obviously reach for blades or clubs and skew guns.
I'll see if I can throw something together stat wise soon and can go from there..
