Cerberus (Resident Evil)

A Cerberus is essentially a Doberman infected with the T-Virus. It is a fairly common enemy in the game. Despite the rotting skin and muscle hanging off their bones they're still surprisingly quick, the virus giving these creatures an insane lust for blood. They'll dive for your arm the first chance they get.

Although quick, they are easy to keep at bay with the Beretta. The worst problem with these is if you manage to get between two or three of them, then you have no choice but to run to a better position. A good method is to shoot to put it on the floor, wait until you see it stand up (or here it growl if it's off-screen), then shoot it again. Repeat this and it will never get a chance to come near you before it's dead
