Vault 106

Vault 106 is one of the Vault-Tec Vaults. It is located south-south-east of Arefu and directly south of Kaelyn's Bed & Breakfast. As part of the Vault Experiment, psychoactive drugs were released into the air filtration system 10 days after the door was sealed. Like Vault 101, this Vault is located in the Capital Wasteland and in 2277, it is mostly destroyed and flooded. For some odd reason, there are still insane survivours inside, with no plausible reason for their existence given (unless they are the Lone Wanderer's hallucination, but this explanation raises the question of where the loot comes from).

A Security terminal near the entrance to the Vault requires a Science of 75 to hack, and contains a security notice from the Overseer. The Overseer's computer requires a Science of 100 to hack, and reveals information about the experiments. Reading these is not necessary to access any area in the Vault.

History
As part of the Vault Experiment, psychoactive drugs were released into the air filtration system 10 days after the door was sealed. It also seems the drugs are still being pumped through the vault, as evidenced by the player's vision suddenly being shaded blue and reality shifting. Accessing the computer terminals also reveals the Vault 106 Overseer knew the inhabitants would be fodder for drug testing and instructed security personnel to tell those in the vault everything was fine.

Enemies
Vault 106 is inhabited by "Insane Survivors", Vault residents who have been driven insane by prolonged exposure to the Vault's hallucinogen-filled air. They wear Vault 106 Jumpsuits and wield a variety of melee weapons, such as lead pipes, knives, baseball bats, pool cues, etc. Despite not wearing armor, the Insane Survivors are slightly tougher than the average Wastelander, which can initially mildly surprise low-level player characters.

At times, the confines of Vault 106 make it hard to wield long range heavy-hitting weapons. With high enough Small Guns skill, the Silenced 10mm is the perfect weapon for quick dispatch of hostile druggies, who should be downed by a single headshot.

On the lowest level of Vault 106, at the end of the Science Lab section, there is a "Survivor", wearing a Vault Lab Uniform and wielding a baseball bat (who oddly has the same ambient/combat voice files as a Raider). The Survivor has very high health (seemingly more than a Super Mutant Brute), and requires a lot of damage to kill. Additionally, an assortment of unusual hallucination effects will occur during the player's fight with the Survivor. After shooting the Survivor a few times, the player will undergo a hallucination where the Survivor disappears, and Butch DeLoria and the other members of the Tunnel Snakes gang from Vault 101 start to appear one by one and attack the player. After killing the hallucinations (each disappears after a single hit), the Survivor will appear again at full health and attack. After the Survivor takes some damage, he will activate a Stealth Boy, (this is evident by the fact that your non-human followers will have a hard time shooting him as well; if it were a hallucination, only the lone wanderer would have a hard time hitting him) which lasts until the Survivor is finally killed. Past the Survivor is a small storage room with assorted misc loot, including a few ammunition boxes and a Mini Nuke.

Loot

 * This Vault houses the Science Bobblehead.


 * A book of Nikola Tesla and You is hidden in one of the 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).


 * 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.


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


 * There are two Vault 106 Master Keys located in the Vault. One can be found next to a functional computer terminal in the North-Eastern corner of a room in the "Vault 106 Living Quarters" only accessible through the "Vault 106 Science Labs". There is also a hidden key at the bottom of a shelf in the store room behind where you fight the Survivor. This key can not be picked up without using the tcl command and going as close as possible to the key.


 * In the Living Quarters you can also find a Recon Armor and a Recon Armor helmet, both are located in a locker which is in the left room when you enter the Living Quarters (verified).

Bugs
In the living quarters on the second floor there is a barricade. Behind this is a locked door (hard) that leads to another door. The game should turn blue and the vault will appear clean like 101 at this point. If you get through the door fast enough there will be an Overseer and if you attempt to talk to him, the Overseer will vanish and end the halucination or the game will freeze (360 confirmed) or crash (PC); however, if you attempt to pickpocket him, the hallucination will stop.

If you initiate combat with the halucination of the Overseer, walking back and forth through the hallway where it turns blue, you will be able to walk into and out of that specific halucination until you kill the overseer. Attempting to loot the remains will act the same as attempting to talk to him when he is "alive."

Appearances in games
