D.B. Technical High School

D.B. Technical High School is a location in the Theater District of Boston It is east of Wilson Atomatoys corporate HQ and south of the Combat Zone.

Layout
The building has three levels, including the basement, first floor, and second floor, with raiders filling the halls and rooms. There are also a few traps, such as bottlecap mines and machinegun turrets. The basement in particular holds quite a bit of notable loot, and is the home of the raider boss Bosco.

In the basement, to the east of the swimming pool room is a metallic door that connects to the generator room in Medical Center metro. There is a barred pair of rooms (one door is barred, the other is chained) on the first floor near the main entrance that can be accessed by falling through a hole in the floor on the second floor. It is also possible to shoot the bar on the back of the barred door through an opening in the wall just past the chained door on the right when approaching from the main entrance. Inside the western room is an Advanced-locked safe and a Novice-locked ammo box. The roof features a few remaining raiders and an explosives box on a fire escape on the eastern side.
