Early in chapter 4 you will encounter your first Brute. These guys seem tough, but they really aren't. The easieset way to take one out is to hit it with staisis and then shoot for the shoulder (yellow spot) while circling around behind the Brute. His back is totaly exposed and his major weak point. Open fire, until he drops.
