Sentinel (The Evil Within)

Sentinel is an antagonist in the survival-horror game, ''The Evil Within. ''Originally a guard dog, the underground cemetary experiments caused it to become horrifically mutated and an almost insatiable hunger for human flesh. 

Description
Like Neun and Zehn, the Sentinel became horribly mutated and murderous after the experiments in an underground cemetery lab.

Before it was the church guard dog but the Sentinel's craving for human flesh became too powerful. It would have six offerings but not even by satisfied then and had to be permanently chained up.

Other than being wrapped in barbed wire and poles, the Sentinel has a second mouth on its neck. It's primary form of attack is to hide behind bushes and charge at Sebastian. However, a freeze bolt or shock bolt can also stop it in its tracks. When the Sentinel charges at the player, a sniper shot to the second mouth can trip it. If the Sentinel is stunned an Agony Crossbow, grenade, shotgun or sniper rifle will do more damage than a handgun.
