Vault 65

Vault 65 is a Vault-Tec vault in Appalachia.

Background
The vault's original purpose in the vault experiment is unknown. There are few remaining references to the vault in the game files, though there are six collision layers that are tagged as being part of Vault 65: one for the atrium, three for a utility room, and two for a living area. A "vault trunk" for Vault 65 exists alongside trunks for Vault 63, 76, 94 and 96. Vault 65 is the only one of these that does not exist in-game.

Appearances
Vault 65 was cut from Fallout 76.
