The Dig

The Dig is a dig site set up by Bobbi No-Nose for The Big Dig quest.

Background
A series of tunnels connecting Bobbi's house in Goodneighbor to a disused subway station, and finally to the stronghold located under Mayor McDonough's office in Diamond City. Contains many ghouls and mirelurks.

Layout
A series of dirt tunnels and buried subway platforms and tracks. Activating weak walls directs a temporary companion to open up a path. The first division in the path leads to a dead end room with a power armor and the other path leads onwards to subway tracks. The next division is on a subway platform that leads through mirelurk infested tunnels; the other path is found to the left down the subway tracks and this path is infested with ghouls and radiation. Both paths lead to a brewery. The brewery entrance is opened via a terminal. A chemistry station is in the same room. The next room is full of ghouls. There is a terminal locked room containing a duffel bag and other loot. Just before is next weak wall is a steamer trunk. The next room contains nothing of note, just the next weak wall which you must activate twice to confirm you are done with The Dig.

Notable loot

 * A fusion core in the first room opened by Sonya and a second one in the room to the north of where the two paths converge.
 * X-01 power armor - In the first room where you give Sonya the order to take a wall down, there are two weak walls. Have her take down the East wall. Inside the armor (incomplete/leveled) is guarded by a Mirelurk king.
 * Another fusion core is in a generator behind an expert locked gate in an optional path opposite to the path leads to a Brewery area that will loop back to the previous subway station area.
 * Overdue book - In the subway station on a shelf in the first train car.
 * Nuka Cola Quantum (Fallout 4) - In the subway station, past the first train car in a Nuka-Cola vending machine, left of the wall that Sonya blasts.
