Vaults are sealed, underground shelters in Fallout 4. There’s only a few of them apart from Vault 111, which is where the protagonist comes from.
You’ll get the chance to explore them during the game, and it’s still unclear what you’ll find. This guide will show you Vault locations in Fallout 4, their histories and what you can get from them.
Vault 114 is located near the coast. You’ll get to visit it on your way through the main story. The quest Unlikely Valentine will lead you there, in pursuit of a private detective that could help you. The vault is being used by the Italian mafia.
