Tunnel Snakes

The  (Established 2268) are a gang of greasers in Vault 101. They wear Grease-style brown leather jackets over their vault suits and have recognizable 1950s haircuts (In game thier hair style is called "Tunnel Snake"). The members of the gang are Butch DeLoria, Wally Mack, and Paul Hannon Jr.. The leadership of the gang shifts consistently between Butch and Wally, with Paul following whomever is in charge at the moment. One other Vault resident, Freddie Gomez, desires membership in the "Tunnel Snakes" gang and the gang members approve of Freddie's bullying of his peers. Freddie's father, Officer Gomez, disapproves of his son's association with the gang.

In the late 2260's, the young Butch is actively organizing the gang and recruiting new members. During the Lone Wanderer's tenth birthday, Butch holds an open panel for possible gang names. Wally suggests "Mackers" and "Hell's Overseers"; whereas, Paul suggests "Grease Weasels", "Vaultikins", and "Vault Dwellers". Butch suggests "Vault Rats" and "Vault Snakes". The name "Vault Snakes" was eventually accepted by the gang, and changed to "Tunnel Snakes". A carefully drawn and designed snake is sewn onto the leather surface of the jackets' backs. The snake's body forms the letter 'S'.

6 years later, on August 3, 2274, the gang members are harassing Amata Almodovar near the classroom. They are chiding her for being a daddy's girl and a daughter of the Overseer. Amata is offended and frustrated by the unwanted harassment of the gang members. In this situation, a player's character could chose one of three possible paths. The paths could involve a player's character helping Amata for good karma, helping the "Tunnel Snakes" for bad karma, or simply ignoring it and forcing Amata to resolve the situation herself.

It is later discovered by the Lone Wanderer while accessing the Overseer's computer that the Overseer has used them to harass people in secret in situations where having his security force do so would be undesirable. ("Escape!")

The gang pretty much ended in 2277 when Paul died, Wally left and Butch was the only member left.

Appearances
The Tunnel Snakes appeared only in Fallout 3.

Behind the scenes
When Butch DeLoria, Wally Mack and Paul Hannon Jr. discuss the gang´s name during the Lone Wanderer´s birthday party, one of the names proposed is "Vault Dwellers", which may be a reference to the main character of Fallout 1. Also, Butch negatively responds to the name, claiming it to be ridiculous.
