Vault 106

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

Background
As part of the Vault Experiment, psychoactive drugs were released into the Vault 106 air filtration system 10 days after the door was sealed. By 2277, the vault's interior is mostly destroyed, and filled with insane survivors. The psychoactive drugs are still being pumped through the vault's air filtration systems, as evidenced by the player's vision suddenly being shaded blue at the same time that hallucinations appear. Information in the vault's computer terminals reveals that the Overseer knew that the inhabitants of his vault would be fodder for drug testing and he instructed his security personnel to tell those in the vault that everything was fine. At the very end of the vault is a cave-like area, where skeletons and other items are located, including a mini nuke, suggesting some of the vault dwellers may have been trying to blow their way out.

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 officer's swords, sledgehammers (at high levels), etc. Despite not wearing armor, the insane survivors are slightly tougher than the average raider.
 * A "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.

When first encountered, the survivor 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. The player then has a hallucination in which the Tunnel Snakes (Butch DeLoria, Wally Mack and Paul Hannon) from Vault 101 attempt to kill the player. 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. It is worth noting that if the Tunnel Snakes are killed by the Lone Wanderer or if the player uses the Mesmetron on them in the hallucination, they just disappear without leaving a body behind. Both killing them and them fleeing ends the hallucination.

Appearances
Vault 106 is mentioned in Fallout Bible 1 and appears only in Fallout 3.

Bugs

 * 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).
 * The game sometimes defaults your body (though not the head) model to the default Caucasian model, staying that way until you reload the game.
 * 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. Killing them grants experience points.
 * If you shoot at Amata she will disappear, but if you kill her with one shot you will receive negative karma and her clones will turn hostile towards you but, upon reaching you, they'll just stand next to you giving you an angry look with their fists up.
 * Despite the insane survivor's natural hostility toward the player, dropping a live grenade on them grants bad Karma.
 * Some hallucinations that are targeted in V.A.T.S. 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.
 * If you shut the main Vault door (the round one) it will appear as if it is not shut all of the way. Another way to see this is to leave the door open and you will see that it is in fact pulled farther back than the rest of the vault doors in the Capital Wasteland.
 * After having killed the Survivor, if the player attacks his/her corpse the blue hallucination tint will appear.
 * Sometimes after killing the Survivor, his/her eyes will blink even though he/she is dead.
 * If you go into the overseer's office and jump near the wall to the right, near the terminal station, you will fall out of the map. One way to get back is to step into the void, and you will teleport back into the hallway before the office.
 * The other is to land on the overseer's tunnel as soon as you jump through the wall, face their office and move all the way to the right, and then jump out through small gap in the map to land on a tunnel below (you will lose some health). From there, turn right and ascend the top of the stairs that are the furthest away, forward, from you.  After you have reached the top of the stairs, continue heading forward until you reach an opened door, directly East of the door to the Vault Entrance.  If you have not yet encountered this hallucination event, you will be teleported into the hall if you close the door and walk over it.
 * Sometimes the game will malfunction, causing the hallucination of Paul Hannon to become real. You can kill him and get a mint-condition Tunnel Snake outfit off of his body.
