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 a virtual reality simulator and cryogenics system containing several simulated utopias including Tranquility Lane. The system should have permitted a select few to live a 'perfect life' practically forever.

What Braun's fellow occupants didn't know was that once they entered the virtual reality pods they were trapped, forced to endure any 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, as the deaths were virtual. Dr. Braun may have been a sociopath from the moment he created the system, or there is the equal (and even more disturbing) possibility that he simply degenerated over time, due to boredom, god-like control of the simulation, and semi-isolation. Regardless, he shows a callous disregard for the psychological welfare of the vault residents, and takes pleasure in subjecting them to greater emotional and physical distress.

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 twelve Tranquility Loungers built 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.

Since it cannot be maintained by any human inhabitants (they're all in the Tranquility Loungers), Vault 112 is instead maintained by a group of Robobrains. The Robobrains are surprisingly non-hostile and greet any newcomers as a "late" addition to Vault 112.

Because of being constantly maintained by robobrains, Vault 112 and 101 are the only intact vaults in the Capital Wasteland. It can also be argued that this Vault never "failed", as its true purpose was to house people in tranquility loungers indefinitely.

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. The correct sequence is broken radio, glass pitcher, gnome, glass pitcher, cinder block, gnome, empty soda bottle. Once the sequence is successfully played, the terminal will appear, with some of Dr. Braun's notes on previous simulations. There will also be a 'Chinese Attack Failsafe'. This failsafe was given to Dr. Braun by one "General Chase". General Chase plays a prominent part in the "Operation: Anchorage" Downloadable Content Pack, another simulation, be it a military war simulation. Initiating this failsafe will spawn several Chinese Commandos outside that kill everyone but Betty and Doc (Your father). 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" and imprisoning Braun alone for eternity for his malice.

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

Hacking the terminal on the ground floor grants you access to a weapons store room.

Loot on one playthrough: Laser Rifle 7 x Microfusion Cell Assault Rifle 3 x 5.56mm Round 3 x Frag Grenade 3 x Pulse Grenade

In the clinics located in the W side of the floor overlooking the pods, there is some armor, including Recon Armor and a Recon Armor Helmet. Note that the lockers on the south of each room are all individual lockers, so each one may contain something different.

2 x Vault 112 Jumpsuit

I have found that there MAY be two invisible 112 jumpsuit in one of the upper right rooms (clinic) of vault 112. There should be a ledge with two of them and jumping on the ledge makes them visible. Otherwise you will be still able to pick them up even if they are invisible. Just look for when it says: "Take Vault 112 Jumpsuit".

Bugs

 * The Robobrains may refuse to speak to you as they are "not at liberty to chat right now". The first one you come across will even stop you just to say she is busy. This may be due to entering the Citadel and accidentally starting the quest Picking up the Trail. However, you can still get a vault 112 jumpsuit from the upper level clinic on one of the tables or the lockers which allows you to access tranquility lane. Note that this particular jumpsuit may be invisible, though you are still able to pick it up if you manage to find its exact position.


 * Upon entering Vault 112 early in the game (example before going to GNR) you may activate the Scientist Pursuit mission via speaking to the Robobrain, and you father is in the lounger. You may enter the assigned lounger as you wish, no glitches recorded (Xbox 360 confirmed). Though this is not recommended as this may affect your ability to help GNR get back on air if you ever want to listen to it far away. Beware the glitches...

Continuity Errors

 * Though the Robobrains insist they will only allow someone to sit in the Tranquility Lounger if you are wearing a Vault 112 jumpsuit, when your father steps out of his, he is still wearing his Vault 101 suit. But this may just be due to the Robobrain reconognising a suit of a certain material and form but not the design as a computer wouldn't.


 * After completing the quest, and when your father has left, the monitor in front of the Tranquility Lounger he occupied still displays his information.


 * The Vault-Tec computer in the citadel lists 85 loungers in the equipment list, however there are only thirteen present, although these may be spares. No reason is given for why the broken chair has not been replaced/repaired.


 * In the safe in The Overseer's office there is a canister of Jet; unless the Jet was somehow placed there recently, this is an error since Jet was invented by Myron long after Braun locked his door and entered his Tranquility Lounger.


 * It is possible that Jet was left there by Pinkerton, since his notes indicate he went to Vault 112 to obtain parts to modify Harkness's memory.


 * It is also equally possible that Jet itself may have been made in some form or another prior to the war, and all that Myron has actually done was figure out how to synthesize it once more. (This is unlikely however, as Jet is made from refined Brahim dung, which should not have existed in the same form pre-war.)
