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.

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 in an option path opposite to a path lead 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.

Appearances
The Dig only appears in Fallout 4.
