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.
- Mass Fusion executive ID - In a desk up the stairs. Gives the user access to the elevator.
- Mass Fusion executive lab password - In the same desk as the ID card. Gives access to the executive research lab terminal.
- Oslow's office recording on a table next to the executive research lab terminal.
- 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.
- If a companion is dismissed while on the roof of the building, they will remain there until retrieved. [verified]
- Provisioners may become stuck on the roof where they will remain indefinitely. Their supply line remains active, however. [verified]
