Vault 76

Vault 76 is a Vault-Tec vault located in The Forest Region of West Virginia in 2102.

Background
Not all vaults were designed with experimental purposes. Vault 76 is one of seventeen known "control" vaults, meaning that it was used as a baseline to compare to experimental vaults. Vault 76 housed 500 occupants and was programmed to open to the wasteland outside 20 years after a nuclear war.

Construction of Vault 76 began in 2065 and ended in 2069, under the supervision of Vault-Tec official Giles Wolstencroft. Vault 76 then debuted seven years later in 2076, in honor of the United States' tercentenary when discussing Vault-Tec's plans to expand. The Vault is scheduled to reopen in 2097, twenty years after the events of the Great War.

Appearances
Vault 76 is mentioned in a terminal entry found in Fallout 3, an alien log in the Mothership Zeta add-on, and by a newscaster at the start of Fallout 4. In Fallout 76, Vault 76 makes a full appearance as a major location.
