Undoubtedly, one of the most iconic aspects of the Fallout franchise is its variety of Vaults, and Fallout 4 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.
