Fallout 4: End of the Line Fallout 4 Guide
Last update: 17 April 2024
How to unlock: Complete Powering Up in the Institute (M5,6).
Quest objectives:
- Talk to Father
- Kill Desdemona
- Kill Railroad leaders
- Talk to Father
Reach the Railroad HQ
Remain in the Institute and meet with Father - depending on how much time has passed since you have completed the previous quest, he can be either in the reactor area, or in his quarters. After the meeting, access the world map and fast-travel to the Railroad HQ, i.e. the Old North Church. Just to remind you, the hideout is in the catacombs, under the church and you follow a quite linear path to get there.
Kill Desdemona and Railroad leaders
Right after you enter Railroad HQ, do not wait until you are attacked by Desdemona and her people, and start attacking them yourself. You can attack all of the NPCs here in any order you want. Due to the relatively small size of the room, you can use grenades, but you can easily do without them. Eliminate everyone in the HQ (you can ignore the P.A.M. Robot because he does not attack you).
After you get the job done, leave the Railroad HQ and return to the Institute to talk to Father. He tells you that your next quest is about extermination of the Brotherhood of Steel.
Quest rewards: Experience points, new quest for the Institute (Airship Down).
