Fort Hagen

Fort Hagen is a location in the Commonwealth in Fallout 4.

Layout
The exterior of the fort is defended by four machinegun turrets Mk that are placed on its roof. There are two ways of entering the fort: Via the roof and via the garage. The garage is directly to the south west of the main entrance. A chemistry station can be found in the garage, to the south of the door leading to the interior of Fort Hagen. The roof entrance can be reached by going around to the west side of the building and climbing the scaffolding. A hatch on the eastern roof will allow the player character to enter the building.

The entire interior is filled with synths. On the upper floor, upon entering the building from the roof, the player character will find a kitchen to their east with an issue of Guns and Bullets on the table. Heading north into the hallway, the room to the east will have a cooking station and a hole connecting it to another room occupied by a machinegun turret Mk III. West of the hallway is room mostly empty save for two Nuka Cola machines. Both rooms connect to another room which has a hole in the floor and also leads to the staircase. Both lead to the second floor.

A protectron can be found and activated in the stairwell of the second floor. The second floor wraps around the staircase. A chained door to the west withholds the player character from heading westwards, so they must loop around the floor eastwards. The room to the south west of the second floor will contain a machinegun turret Mk I. Continuing west and then north the player character will find an advanced locked terminal with an active mine lying under it and a military trunk with ammo and weapons next to it. The console will allow deactivation of the nearby laser turret and open the magnetic door further back in the room. Across from the magnetic door, the player character can unblock the door heading back to the stairwell. At the back of the room is an elevator, which leads to the ground floor. Elevator is blocked by wooden bars until some level of main quest progress.

From the elevator, the player character is confronted with a passage with a room at the end occupied by a machinegun turret Mk III. The passage has two doors on its east side. The first one can be unblocked from this side and is the door on the ground floor which leads to the garage entrance and the stairwell. In between the first and second door is a tesla trap. The second door leads to a room with armor and weapons workbenches on the south and east walls. In the room at the end of the passage is a staircase heading down. Behind the security gate is another tesla trap.

Heading down another set of stairs leads to another security gate, this one guarded by a machinegun turret Mk I. At the end of the hall is a door leading to the Fort Hagen Command Center.
