Detailed walkthrough[edit | edit source]
When the Sole Survivor arrives at Vault 81, proceed to connect their Pip-Boy to the entrance button in an attempt to open the vault doors; however, the door will not open and instead Scott Edwards will respond to the activation attempt through the intercom system. Overseer Gwen McNamara will dismiss him and take over the conversation.
McNamara will advise the player character that if they want to enter the vault, they need to bring three fusion cores as a means of payment. Alternatively, the Survivor may pass a Hard speech check. If the choice is made to part with the cores, they will be compensated with 100 bottlecaps by the overseer. Full access to the vault will be granted regardless. Overseer McNamara will welcome them and they may trade and interact with the residents of Vault 81.

Notes[edit | edit source]
- Used cores will fulfill the requirement just as well as fresh cores. If entering the vault early in the game, when cores are not widely available, this should mitigate the relatively high cost of admission while still getting some use out of power armor. However, if one has both used and unused cores, the game may prioritize the unused cores when removing from your inventory, so be sure to store them, drop them, or hand them to a companion if you only want to give up used cores.
- If the Survivor has any companions currently in their service, vault security officer Scott Edwards will express his concern to Overseer McNamara, but she allows the companion to remain in the vault without incident.
- If wearing power armor, the overseer will advise that some of the residents will be uneasy.
- Upon entering the vault, dropping ones stock of fusion cores once the overseer begins to talk will allow them to enter the inner vault without losing any fusion cores, and still get the 100 caps compensation.
- The door leading further into the vault is marked 'Inaccessible' until the conversation with McNamara has been completed.
Bugs[edit | edit source]
- Playstation 4 Xbox One When you pass the persuasion check there is a chance that the door used to head deeper into the vault will not open and remain inaccessible. There is no currently found fix for the issue.[verified]
- PC Playstation 4 When you enter the vault, McNamara will finish her conversation with Calvin and then just look at you. If you try to interact with her she will just stare at you. Saving and reloading the game does not appear to solve this issue. It may be caused by dropping your cores after entering the vault but before talking to McNamara; picking them up again resolves the issue in this case. [verified]
