On the Sole Survivor's first interaction with Austin Engill, he will offer to take the player character on a tour of the vault for a price of 5 caps or for free if the player character successfully passes a Charisma check. Austin will then proceed to show the main rooms of the vault to the Sole Survivor. Once the tour is completed, the player character will receive 75 experience points.
- The quest can be failed if the player character moves too far away from Austin during the visit. Additionally, the quest will also fail while conversing with NPCs while on route to different locations in the vault.
- If the quest is started late at night, it is possible to become "stuck", as Austin will go to bed without the tour completing. To avoid failing the quest,one may need to wait for him to wake up again.
