Guardian

Guardians are the result of the Necromorph infection anchoring a torso to flesh growing on the walls, and as a result this is what grows. You can tell when one is nearby when you hear moaning and groaning. Quite possibly, the groaning is a lure for unwary humans. However, some have been observed as being silent until engaged in combat. Unable to move and attack enemies unless they move up close to the Guardian, the Guardians have been observed utilizing embryonic spawn that they spit out in front of themselves which will aid in attacking detected threats.
if a person is to get too close to a Guardian then it can use its tentacles to whip his/her head,arm,leg off or even rip them in half.
