Mass Fusion Executive Suite

(Redirected from Mass Fusion executive suite)

The Mass Fusion Executive Suite is a location in the Commonwealth in Fallout 4.


The Sole Survivor is teleported to the area as part of the Mass Fusion quest. In the Brotherhood of Steel version of the quest (Spoils of War), the player character is dropped off by vertibird.


The suite is comprised of the upper levels of the Mass Fusion Building in downtown Boston. A series of rooms with an elevator leading down to the Mass Fusion Building. It also has a reactor room.



  • The elevator ID card needed for the Mass Fusion quest does not spawn until the player character begins the quest.
  • By jumping off the top of the building towards the southeast, it is possible to land in Goodneighbor. Instead of continuing to fall, one may arrive at the entrance.
  • As of patch version 1.9, the executive suite cannot be discovered until the quest the Nuclear Option reaches its conclusion.


The Mass Fusion Executive Suite only appears in Fallout 4.
