Mass Fusion Building

The Mass Fusion building is a location in the Commonwealth in Fallout 4. This building is one of the Commonwealth's most unmistakable landmarks due to its size and unique architectural design.

Notable loot

 * T-45 power armor worn by the Gunners Commander.
 * Strength bobblehead on the head of the giant interior statue (accessible from the floor with the Gunner Commander, powered elevator and exits to the Mass Fusion Balcony).
 * Overdue book on a desk on the fourth floor. You have to go up to the fifth floor and go back down to reach it, another is on a desk on the reactor level.
 * Possible Nuka Cola Quantum on the ground floor in the vending machine to the left of reception (random spawn, may be a different variety of Nuka Cola instead).
 * Mini nuke on the same floor as the bobblehead in the room to the north west.
 * Fusion core on a desk after jet packing through a hole in the wall at the very top of the elevator.
 * Tesla Science Magazine on the computer bank, southeast mezzanine room, upper offices above the glass floor(on the same floor elevator power is restored). This magazine is inaccessible until finishing quests very late in the game, but you can get it beforehand with jetpack mod on power armor.
 * Freefall Legs found at the top of the interior of the building, in an area only accessible using the jetpack power armor mod, using the trash can wall climbing glitch, or during the quest Mass Fusion.
 * Stealth Boy found in the same room as the Freefall Legs, on top of a small bookshelf.
