Detailed walkthrough

When the Sole Survivor arrives at Vault 81, they proceed to connect their Pip-Boy to the entrance button in an attempt to open the vault doors, however they are greeted by the present occupants of the vault, who are descendants from the original members of Vault 81.

The vault is one of the few that hasn't been captured or overthrown, and remains orderly and secure for the residents.

The Sole Survivor from Vault 111 is told by the overseer of Vault 81 that if they want to enter their vault, they need to bring 3 fusion cores as means of payment. Alternately the Sole Survivor may pass a difficult persuasion check to get in without paying the cores. It is possible to fail and succeed with 8 Charisma.

When having returned with the cores, the Sole Survivor will be allowed to enter the vault, and Overseer Gwen will welcome them, and they will be allowed to trade and interact with the residents of Vault 81. Overseer Gwen explains to the Survivor that although the vault can provide a lot of resources for themselves, sometimes they require outside materials to make sure the vault is stable.

Notes

  • The trader located outside the entrance to the vault will occasionally carry Fusion Cores, making this quest a simple case of walking out and back in
  • Vault 81 is located in Allston, Massachusetts in current day Boston.
  • If the Sole Survivor has any of the companions currently in the their service, vault security officer Scott Edwards will express his concern to Overseer McNamara, but she allows such companion remain in the vault without incident.
  • If the Sole Survivor is wearing power armor, the overseer will inform you that the residents will be uneasy.
