The brutes aren't as hairy as you think. In fact, they seem to have less hait than us. (only it's vere long in the few places it is)
I'd suggest making a muscle suit, then putting trash bags on them to look like skin. Paint with latex paint, adding more texture while you do that. Find a furry fabric, and stitch it on (Torso and, legs and arms only, this is for the fine hairs.)
After all that, do an old fasioned brute mask, using thousands of online tutorials. Punch some hair on that. And voaleh...eh (can't spell) A naked brute.
How to get in or out is your problem. Weapons, props and armor are also your problem :roll: . (or link's. I'd love to see a B-shot from him)
I'm not commanding anything, I'm just telling you exactly what I'd do. (and hopefully will.)
