Secrets Revealed

Secrets Revealed is a main quest in the Fallout 76 Wastelanders update.

Walkthrough
Talk with Slick and AC, members of the Secret Service. After the vault malfunctioned and trapped them inside, they need help with re-enabling the vault's reactors. Heading north, through the recently-opened door will bring you to Digger, who tells you that to re-enable the reactors, the reactor room must first be vented from the control room. Digger recommends sneaking past the hostile ghouls in the room.

Then, follow the corridor to the east counter-clockwise until the stairs can be taken to the next floor. Now follow the corridor clockwise to the control room and press the emergency ventilation button. After ventilation has been completed, the control room's door will reopen, and the reactor room's turrets and robots will be re-enabled, taking care of any remaining ghouls in the room. After the reactor room has been cleared, head to the gold processing room and take the bullion supply from the chest, in addition to the remaining 1000 gold bullion in the room.

Upon exiting the room, you will meet the agents again. You will have to either convince them that Digger, now a ghoul, is harmless, or have him be killed. Afterwards, follow the agents to the gold processing facility. While talking with AC, Paige or Meg appear, depending on the faction chosen to raid the vault. Either give them the 500 bullion as promised, give 250, and give 250 to the other faction, or give them nothing. Optionally, talk with Johnny Weston, or Radcliff and Jen before talking with their respective leader to complete the quest.
