Located on the edge of the Mire, this bunker belonged to a Free States family before the pumps failed and it flooded.
This Free States bunker has been left in disrepair and can be inhabited by packs of animals. A chemistry station can be found immediately to the left upon entering. Going down the stairs to the right, the path eventually leads to a kitchen and dining area, with a brewing station along the eastern wall. Connected to it is a generator room with a number of large, orange vines coming out of its walls, a common sight in the bunker.
The other side of the bunker, down three stairs, is a flooded living area. To the east is a laundry and storage room with a safe, while a bathroom with a first aid box on the wall can be entered to the north.
Abandoned bunker safe key - In the bathroom sink.
The abandoned bunker appears only in Fallout 76.
