The Creeping Stranger is the failed attempt at creating Strangers and it is a far cry from the original models. They are fairly durable in terms of HP and their body cannot be destroyed before the head. Their Berserker inflicting attack does come with some drawbacks but isn't as dangerous as Silence or Darkness. They aren't too dangerous though and can be killed easily, in one shot with the Stungun, a Buckshot round or with Plasma.
