Here's a rough concept I decided to draw before going to bed.
The basic idea is there's going to be a swat team of these uniform guys. And this guy is probably going to be the tank one of the team who does not really move as much but bombard enemies with ammos or flame thrower of such sort. Idea is not very clear yet, I'm still throwing ideas as I go. See how it'll turn out, but for now, bed time!! :)
