Sentry

Sentries are a hostile robot stationed either in item rooms or at the intersections of some hallways. They carry a variety of weaponry and come equipped with armor plating, making them more difficult to destroy than their equivalent Grunt. Sentries will chase the player if they catch sight of it - however, their treads make them easy to get away from given enough move speed.
