Vault 24

Vault 24 is one of the Vault-Tec Vaults. The Vault's location, inhabitants, and purpose is currently unknown. A Vault 24 jumpsuit is the only trace of the vault in the game, which can only be accessed by console commands. Predictions regarding the fate of the vault could be that it was somehow destroyed when the bombs fell by being caved in and sealed off from the outside forever or that a vault jumpsuit with '24' was simply made for a vault that was never built in time before the great war.

Appearances
Vault 24 was referenced in the game files of Fallout: New Vegas in the form of a jumpsuit for the vault, but was not included in the game.
