Vault 112

Vault 112 is one of the Vault-Tec Vaults located in the Capital Wasteland. It 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.

Game Bug
In the initial retail release of Fallout 3, if the player finds Vault 112 before visiting the Galaxy News Radio building, the dialog options will occur as if they had, thus causing confusion since the player will know things they haven't yet experienced in-game. This is likely a slip by the developers that may be fixed in a future patch.

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. But there will also be a 'Chinese Attack Failsafe'. Initiating this failsafe will spawn several Chinese Commando's outside that kill everyone. A door will also spawn near Betty, allowing you to leave the simulation and walking up to your father.
