Notes:

Because of the fact that it's a corpse wrapped around a metal body like a Christmas present, I'd imagine a necromorph like this to either be a boss or a rare type of necromorph. Since it's mostly made of metal, I doubt a weapon like a plasma cutter or a Remote Control Disc Ripper would cut off limbs. An Ore Cutter Line Gun or a Javelin Gun may or may not be effective though.
