Vault 100

Vault 100 is one of the Vault-Tec Vaults. The Vault's original purpose in the Vault Experiment is unknown. The exact location is also unknown.

Appearances
Vault 100 was referenced in the game files of Fallout 3 in the form of a Pip-Boy icon for an unimplemented Vault 100 jumpsuit. This icon is also present in the game files for Fallout: New Vegas as legacy content. There is a possibility they are there to provide G.E.C.K. users with a vault idea.
