Vault 106

Vault 106 is one of the Vault-Tec Vaults located in the Capital Wasteland. It is located south-south-east of Arefu and directly south of Kaelyn's Bed & Breakfast, a bit north of Jury Street Metro Station.

History
As part of the Vault Experiment, psychoactive drugs were released into the air filtration system 10 days after the door was sealed. By 2277, it is mostly destroyed but filled with Insane Survivors. The drugs are still being pumped through the vault, as evidenced by the player's vision suddenly being shaded blue while hallucinations appear. Information in the computer terminals reveals that the Overseer knew the inhabitants would be fodder for drug testing and instructed security personnel to tell those in the vault everything was fine. At the very end of the vault is a cave-like area, where skeletons and other items are located. It can be assumed that all of the sane residents of the vault went into that cave with all of the food and water they could, waiting for help or possibly trying to dig back to the surface.

Enemies

 * Several Insane Survivors inhabit Vault 106. They wear Vault 106 Jumpsuits and wield a variety of melee weapons, such as lead pipes, knives, baseball bats, pool cues, Chinese swords, sledgehammers (at high levels), etc. Despite not wearing armor, the Insane Survivors are slightly tougher than the average Raider enemies, which can initially mildly surprise low-level players that can break into Vault 106 early on in the game.

It is worth noting that if the Tunnel Snakes are killed by the Lone Wanderer in the hallucination, they just disappear without leaving a body behind. Killing all of them ends the hallucination.
 * A "Vault 106 Survivor" (who has the same ambient/combat voice files as a Raider) is on the lowest level, at the end of the Science Lab section, wearing a Vault Lab Uniform and wielding a Baseball Bat. The Survivor, after taking some damage, will activate a Stealth Boy (this is evidenced by the fact that your non-human followers will have a hard time shooting the Survivor as well; if it were a hallucination, only the Lone Wanderer would have difficulty). The Stealth Boy will remain active until the Survivor is killed. When first encountered, the survivor will disappear, and the player has a hallucination in which the Tunnel Snakes (Butch DeLoria, Wally Mack and Paul Hannon) from Vault 101 attempt to kill the player. It would seem that followers also suffer this same hallucination as they will also attack the Tunnel Snakes. After the Survivor sustains some damage, the Tunnel Snakes will use Stealth Boys and flee, and the player will see as if in a hallucination (with the purple tint). This will end after killing the survivor.

Loot

 * The Bobblehead - Science is located in the Living Quarters. After you first enter the Living Quarters (it's a two level room: top level), enter the door on the far left hand side of the room, diagonally across from where you first enter. Proceed to a hallway into a fairly large room (for a vault); this room has 3 windows on each side that look into a subterranean cave. The bobblehead is on a bookshelf against the back wall (3rd shelf).


 * A book of Nikola Tesla and You is hidden in the stack of three wooden boxes on the teacher's desk inside the classroom in the Living Quarters (the room to your left after you first enter the Living Quarters area).
 * Downstairs in main room of the Living Quarters (Directly below where you enter). Hallway and room on west side have a bit of ammo, chems and, other loot. There are 3 Ammo Boxes with misc. ammo, a Mine Box, Grenade Box, a couple loose frag mines, approx. 5 bottles of Rad X, 2 First Aid Boxes, and a couple boxes of Mentats. There is a box on the shelf in the hallway with 5 bottles of Turpentine. There is a safe (Hard) behind a locked (Average) door at the very south on the very bottom floor (It's a dead end). Found very few caps and nothing more.


 * A book of Tumblers Today is on the Science Lab level, two floors down from the Science Lab level entrance, inside a large room with 2 lockers visible from the door. It's on an overturned mainframe cabinet in the south west corner of the room with two milk bottles on it.


 * Finally, there is a Mini Nuke in the final room of the Science Lab area, just past the fight with the Vault 106 Survivor.


 * There are two Vault 106 Master Keys located in the Vault. One can be found next to a functional computer terminal in the northwest corner of a room in the Living Quarters that is only accessible through the Science Labs. (You can see the room and the Science Lab's door through windows in the Living Quarters, but have to go through the Labs to get to it.) There is also a hidden key at the bottom of a shelf in the store room behind the one that you fight the Vault 106 Survivor in. This key can not be picked up without using the tcl command and going as close as possible to the key.

Bugs

 * Attempting to speak with the Vault 101 Overseer hallucination may cause the game to freeze (confirmed PS3, XBox 360, PC).


 * The hallucinations of your Dad that appear throughout Vault 106 are always the default Caucasian model, even if you choose a different race for your player character (and thus also for your father). (confirmed PC)


 * At higher levels when attacking the Vault 106 Survivor, even though the survivor might be dead, the Tunnel Snakes will literally "float" into the room without the blue hallucination backdrop. (confirmed PC)


 * If you click the right stick on the Vault 106 survivor after killing him his body floats as usual with other objects clicked on, but his body might go inside out and looks as if his arm is going through his leg and his leg is coming out of his head and so on. (Confirmed on the Xbox 360)
 * In the room before the hallway leading to the room with the bobblehead, there's a locker that will not read "[EMPTY]", even when so.


 * If you shoot at Amata she will disappear, but if you kill her with one shot you will receive negative karma. (confirmed PC, Xbox 360)


 * Despite the Insane Survivors' natural hostility toward the player, dropping onto them a live grenade grants bad karma. (confirmed Xbox 360.)


 * There is a bug that happens when you enter the Vault where that the blue haze will not appear, and no hallucinations will occur. (XBox360, PC)


 * Sometimes when you enter Vault 106, the door will close thus making it impossible to exit. (confirmed Xbox 360)


 * Some hallucinations that are targeted in V.A.T.S, they will cause the game to crash if they disappear while V.A.T.S is zooming in or the player is taking out their weapon. (confirmed Xbox 360)


 * When the hallucinations appear, you can walk the other way until the color turns back to normal, and keep going without the Vault 106 survivor attacking you or the Tunnel Snakes popping up. (confirmed Xbox 360, PS3)


 * In the Overseer's office, along the North wall, you may be able to drop through the floor/wall. If you do so, you will fall outside the normal passageways, and eventually will be placed back into the Vault. (Xbox 360)


 * Also upon entering the Overseer's office, if the player attempts to pickpocket him just before he disappears, the game will crash. (PC)
