Vault 51

Vault 51 is a Vault-Tec vault located in the Forest region of Appalachia in 2102.

Background
As with the other vaults, Vault 51 was sealed shut during the Great War in 2077. Twenty-five years later in 2102, the vault remains sealed.

Vault 51 contained a ZAX that was guided by Robert Baker to choose an overseer. Reuben Gill was eventually chosen as overseer but Zax eventually turned on him. The overseer eventually escaped his vault with the goal of finding help from the Vault 76 residents to shut down the ZAX. However, he died before completing that mission.

Vault 51's experiment tested both tribalism and the ZAX unit turning the vault dwellers against each other.
