Undoubtedly, one of the most iconic aspects of the franchise is its variety of Vaults, and features seven of these underground bunkers for the Sole Survivor to explore.
Despite being advertised as places of safety during a nuclear war, Vault-Tec's Vaults were anything but, with most being home to terrible experiments.
Learning the story of each Vault can be both rewarding and interesting, with each one having a unique, tragic tale. 's Vaults are found in various locations all over the Commonwealth, with five found in the base game and two added with DLC.
While most can be found while completing quests, there are a couple that will require the Sole Survivor to seek them out on their own. These dangerous Vaults are all worth exploring at least once, to learn their secrets and find their loot, but a few are worth return trips.
Vault 111 is the first Vault any Sole Survivor will visit, as this is their local Vault, which they will flee to at the start of during the introduction sequence and serves as a starting area.
