The Trail Ends Here
It seems you’ve come around to Desdemona’s way of thinking. At the Railroad HQ, you listen to her plan and agree with it.
After relaying into the Institute, you find Z1-14 removing threats in the relay control room to allow Desdemona and her crew to teleport in. Speak with your leader, who hands you a device critical to finishing these activities.
Fusion Pulse Charge
Your infiltration takes you through the Old Robotics area, where you should expect heavy synth resistance and active laser turrets. Locate and drop through the hatch to enter the Institute BioScience laboratory. Weave your way through to the reactor entrance. It isn’t surprising that the blast door has sealed the reactor down.
Press the button at the central elevator. Access Father’s quarters and receive the override password after speaking with him. Utilize it, or hack the terminal (Novice). Now activate the master security lockdown override.
The Railroad Terminus
Work your way to the Institute Advanced Systems and into the reactor chamber. A heavy synth presence is expected. Access the reactor door and activate the reactor housing.
Tinker Tom relays you back to the Institute relay control room. Speak with Desdemona before Tom interrupts, announcing an unexpected arrival in the vicinity. Speak to the tiny tyke:
- Agree to take him under your wing and save his life. Tinker Tom ensures his safety. Find him at the Railroad HQ.
- Tell the diminutive fellow that he must remain here.
Once you step into the relay and are teleported to the roof of the Mass Fusion building, you’re able to definitively conclude the Institute’s operations in Boston for the foreseeable future. Your Main Questing ends after you speak to Desdemona about the future of the Commonwealth.
