Zzz... Three angry deathclaws make for a lot of reconstructive surgery.

Sink Auto-Doc is an Artificial Intelligence at Big MT in Fallout: New Vegas.


The Sink's Auto-Doc is a prototype Auto-Doc built by Dr. Mobius before he left the Think Tank and all of The Sink's systems were disabled. When its Sink Project: Auto-Doc is recovered from the Y-17 Medical Facility, the Auto-Doc speaks. When inactive, the unit may snore loudly, ramble on about patient injuries such as shoe lung while asleep, or make passing comments on the Courier's general health.

It can perform complex medical procedures like implementing implants. It can give a basic physical exam, cure radiation sickness, lacerations, broken bones, and chemical addictions, give a haircut, provide facial reconstruction, implement implants, switch out brains, spines, hearts, and perform psychiatric evaluation. It is still located in Big MT's the Sink.

The Auto-Doc was responsible for removing the Courier's brain, a procedure that would normally result in its subject becoming a Lobotomite. However, due to the cranial injury from being shot in the head, the Auto-Doc was forced to adjust the operation routine and was successfully able to perform the intended operation.[1]

Behind the scenes

  • One of the Sink Auto-Doc's sleep talking lines is a reference to "Dem Bones."


  • PCPC Playstation 3Playstation 3 Xbox 360Xbox 360 Even with all the holotapes located & installed, the only options available while interacting with the Sink Auto-Doc are heal yourself & respec your traits. This bug only affects the Spanish version of the game. The 3rd option in the menu is left blank due to an error in language translation, so only two options are displayed. [verified]
    • It may be worked around by temporarily switching the game's language to any different language than Spanish, or mod the game and add the missing translation.
  • PCPC Playstation 3Playstation 3 Xbox 360Xbox 360 If the Sink Auto-Doc is used to remove the Skilled trait, the trait's bonus remains (the penalty does not) or if the player re-selects it, they gain an extra 5 more skill points on top of the original 5 point bonus (giving 10 points per skill). In the latter case, you will receive the penalty as normal. [verified]



  1. The Courier: "A cranial injury. From the attack outside Goodsprings."
    Doctor Mobius: "[SUCCEEDED] Yes. Very good. I should have Mentats ingest you instead of the other way around. Mmm. Mentats. In any event, you showed up at the Think Tank, and because you had suffered a cranial injury in just the right place... Bullets in the head are usually much more fatal, and yours was a light case of bullet-head-itis. But... it was enough for the Auto-Doc in the Sink to change its programming to fix the problem. And the brain extraction technology for once, worked. That gave the Think Tank the knowledge its brains shouldn't... couldn't... sh'couldn't possess. With that knowledge, the procedure can be reversed. If they obtain that procedural data, they can use it to mush and modify their cranial selves into hosts to slip past the Radar Fence, I'm sure of it. And once they're off the reservation..."
