The boss has a big build similar to the Double Headed Zombie with green skin with blood all over its hands and body, and a large head which its eyes are covered by bandages. It also mutated a second head on its left shoulder that has a scrub cap and surgical mask with red eyes and a mutated left foot. It has a black apron with an I.D. on it.
It will slowly stumble towards the player until it is close enough to attack. In which it will attack by swinging its weapon at the player, it will also attack the player's pet.
- Hospital (Boss)
- It is one of the few bosses that wields a weapon, the others being the Wizard Boss, Admin, Pyramid Head, and Rider.
- The sounds of its chainsaw can be heard whenever the player is close.
- The chainsaw can't be picked up after the boss dies.
- It can not see with its blindfolded main head. Where it would rely on its second head for sight.
- The chainsaw it wields may be a parody of a "surgical saw".
- As this boss is very slow, run to the end of a long hallway and keep hitting it with headshots from a sniper
- If you are at lower levels, do not engage this boss with a melee weapon, this can cause heavy damage upon you.
- But if you have to, just keep moving back and forth whilst attacking the boss. All of the monsters in the game have to stop if they want to attack another entity, so keep that in mind.
