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.
 * 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.
 * Nuka Cola Quantum on the ground floor in the vending machine to the left of reception.
 * 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 in the southern-most room on the same floor elevator power is restored (the floor above the one you exit the elevator after its power is cut). 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 or during the quest Mass Fusion.
 * Stealth Boy (Fallout 4) found in the same room as the Freefall Legs, on top of a small bookshelf.
