That big fella in black armor with a chaingun was a tough cookie! :D
You have to melee it first to remove its helm(hard stuff) then using the guns from dead enemies(a lot of 'em), shoot its head like a pro-leveled sharpshooter.
I love the game, just the right amount of gore to start me up!
The recoil was there and I can merely feel it, ejected casings flies and bounces realistically!
PS. I love the scoped FN FAL. Pin-Point accuracy guaranteed! :D
