The Burkittsville Vault is a Vault-Tec Vault in the town of Burkittsville mentioned in the cut Hamilton's Hideaway terminal entries. In the days following the war it was sealed. A group of crazed cannibals set up camp near the Vault entrance, ambushing anyone who tried to reach it.
The Burkittsville Vault is supposed to be mentioned in Fallout 3. However, it was cut from the final game.
