When teleporting to the Institute, one must talk to Father. He will ask you to craft a speech near a microphone beside a terminal near him. He will then give the task of going to Diamond City to boost the range of Diamond City Radio. Once arriving to Diamond City, head over to Travis's shack where he broadcasts from. When entering his shack, look on the ground for a box of radio things to his transmitter gear.
Place the gear in the right spot:
- 'Radio thing with the buttons' goes to the left.
- 'Radio thing with dials' goes in the center.
- 'Radio thing with the tubes' goes on the right.
After that is done, return to the Institute and go to Father, who is waiting in the reactor room where he will prompt to put in the Beryllium agitator that the Sole Survivor acquired from the previous mission into the reactor.
When placing that in the reactor, one must activate it using the terminal near it. The door to the reactor will close and the player character will have to talk to Father, after which he will ask to attend a board meeting as the director. There the Sole Survivor will discuss the future plans of the Institute.
The player character will discover that the Directorate already have made the decision to destroy the Brotherhood of Steel. If arguing for a solution that avoids conflict, it will be rejected because The Brotherhood of Steel already started it by invading the Commonwealth with their troops and airships.
One has to decide whether the Institute shall focus on further development of synths or weapons. When the meeting concludes this quest completes and the quest End of the Line starts automatically.
- Choosing any of the options during the crafting of the speech has no effect on the Institute's stand or ending.
- The speech can be heard intermittently on Diamond City Radio after quest completion.
Behind the scenes
The Institute's reactor shape is based on the tokamak design used in fusion research over the last few decades.
- Playstation 4 When talking to Father, sometimes he will tend to walk away, cutting out the dialogue and resetting it. [verification overdue]
- Playstation 4 Sitting down will not start the meeting. One possible cause for this bug might be the destruction of the Brotherhood of Steel prior to finishing this quest.[verification overdue]
- PC When entering the reactor room Enrico Thompson will have change his yellow institute coat with a blue one while still performing in the Facilities department.[verification overdue]
