Vault 112

Vault 112 is one of the Vault-Tec Vaults located in the Capital Wasteland. It was built well hidden underneath Smith Casey's Garage, north-east of Girdershade. The vault was built to house and tend to the needs of Dr. Stanislaus Braun, creator of the Garden of Eden Creation Kit. Within it Braun invented Tranquility Lane, a virtual reality simulator/cryogenics system which allowed him and a select few survive. But what Braun's fellow occupants didn't know was that they had fallen into Braun's trap for once they entered the virtual reality pods they were trapped, forced to endure the psychological torment that Braun proceeded to inflict upon them over the coming centuries. He would proceed to kill each one of them in the most horrific and graphic ways, each time wiping their memory so he could do it all again.

Vault Layout
Vault 112 houses an entrance area similar to Vault 101, which serves as the airlock and the only connection to the outside world. A single passage in the entryway leads down to the main hall. In there are thirteen Tranquility Loungers build around a big pillar, each connected to a terminal which monitors the respective conditions of the "subjects" inside the loungers. There is also another Tranquility Lounger, found in the Overseer's Office, located south of the main hall. The only medical unit of the vault is accessed east of the main hall.

Tranquility Lane System Fail-Safe
It is possible to get yourself and your father out of there without having to do the tasks Betty gives you. Inside the abandoned house you will find several objects. Activating these objects in the order of tones that Betty whistles while playing outside (an error sound will play when you've picked the wrong object) will make a terminal appear with some of Dr. Braun's notes on previous simulations. Click broken radio, glass pitcher, gnome, glass pitcher, cinder block, gnome, empty soda bottle. There will also be a 'Chinese Attack Failsafe'. Initiating this failsafe will spawn several Chinese Commandos outside that kill everyone. A door will also spawn near Betty, allowing you to leave the simulation and walking up to your father. You will gain good Karma for this, releasing the residents from their torment.

Notable Loot
Several Stimpaks and Chems can be found in the medical unit, accessed east of the main hall. Rather high Skills in either Science or Lockpicking are required to open the door.
