Fort Hagen is a former United States Army base located in the Commonwealth.


Before the Great War, Fort Hagen was an important military command facility.[1] The old Army base incorporates housing for the base's personnel and a variety of medical and repair facilities. Luckily, the Fort proper remains firmly sealed away from scavengers... a perfect base of operations for a man named Conrad Kellogg, the infamous mercenary working for The Institute.[2]



The Fort is accessible from a door one level down in the parking garage, or from a rooftop hatch. The parking garage is on the southern end of the fort, while scaffolding on the northwest side of the fort leads up to the roof.

Ground floor

Rooftop access leads to the ground floor of the base, which served as the offices for government employees. A cooking station lies in a room in the southeast corner of the floor and the exit stairwell leading further down into the base is in the northwest. The stairs lead to several more offices, the southeastern of which contains a chemistry station. The stairway leads further down, leading to the floor accessed by going through the fort's parking garage (detailed below).


The parking garage entrance enters a basement with a stairwell leading up directly on the left, and another hallway interests the entrance. On the north end of the hallway is an elevator that leads up to the main floor; continuing south of this hallway, there is a maintenance room with an weapons workbench and armor workbench a room leading further down some stairs. The hallways and stairwells continue to the Fort Hagen command center.

Fort Hagen command center

The Fort Hagen command center is opens to a room lined wall to wall with terminals and switchboards. However, the doors lining it are all initially locked, forcing exploration down the corridor. The end of the corridor has an elevator (or ladder for Xbox one) leading to the rooftop; there is also a connecting hallway leading south from this corridor, passing by barracks before turning and going down to the a generator room and later a cafeteria. Past the cafeteria is a maintenance tunnel lined with pipes and wires. The tunnel terminates in another section holding some living quarters before getting to the command center proper, which holds Kellogg.
