Painkillers are one of two variants of the Surgeon found within Asylum. They were introduced in the V1.5 Beta along with the Sentinels, the Seraph Queen, the Seraphs, and the Deadworms.
Painkillers are different from the two other variants as they wear a noticeably different outfit. They are stronger than the Surgeons but weaker than the Sentinels because of the many shots they take from a charged Shadow Gun. These sinister foes are found a little later in the game, found in the Playrooms, the Experimentation Rooms, the Lavaducts, the Fogometers, and the Engine Block.
