Vault 81 (quest)

Vault 81 is a side quest in Fallout 4.

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 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 Survivor may pass a difficult persuasion check to get in without paying the cores.

When having returned with the cores, the 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.

Bugs

 * Once you enter the vault dropping your fusion cores once the overseer begins to talk will allow you to enter the inner vault without losing any fusion cores.
 * 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. I can verify that this bug is still active on the Xbox One
 * When discovering the vault sometimes random explosions will ring out and any explodable or objects will catch alight and quickly explode
