Next, defeat everyone in the Relay Room since you'll need it to bring in the rest of the Railroad.

After everyone arrives in the Relay Room, speak to Desdemona, and she'll give you the Fusion Pulse Charge that you'll need to plant later on.
4 Head to the Main Square

The Nuclear Option (Railroad) Walkthrough | Fallout 4 (FO4)|Game8 (5)

Proceed to the Main Square by entering the Old Robotics Department. Head down to the bottommost area either by jumping down upon reaching the entrance or by taking the longer route through the facilities on the left. Regardless of the path you choose, make your way to the end of the last floor to find the hatch leading to the Bioscience Department.

When you reach the Bioscience Department, take the path to the right. The exit should be on the left side of the Gorilla enclosure. Take that exit to reach the main square.

Defeat all enemies inside the Main Square, including the Coursers sent to attack you. Make sure you defeat all enemies, as this is the only way to trigger Tinker Tom's announcement, which allows you to access the elevator in the middle again to reach the Father's room.
5 Issue a Lockdown Override
The Nuclear Option (Railroad) Walkthrough | Fallout 4 (FO4)|Game8 (8)When you reach The Father's room, proceed to the second floor to locate the terminal. Use it to issue a lock override, unlocking all doors on the main floor and granting you access to the Reactor.

You can also speak to the Father to gain access to the Synth Shutdown command. However, this requires passing charisma checks, so make sure you have Charisma perks before attempting this. Activating this command shuts down some of the deployed Synths, reducing combat pressure as you proceed to the reactor.
6 Reach the Reactor

The Nuclear Option (Railroad) Walkthrough | Fallout 4 (FO4)|Game8 (10)

Proceed to the Advanced Systems and enter the room directly ahead. Follow the path, and it will lead you to the reactor. Keep in mind that the path will be littered with turrets and Synths, especially in the main room, so be sure to defeat them to reach the reactor quickly. Plant the Fusion Pulse Charge immediately as soon as you reach the reactor.
7 Talk to Shaun and Tinker Tom

After planting the Fusion Pulse Charge, rush back to Desdemona to teleport back to the Relay Room where Shaun now waits with the rest of the Railroad. Talk to him and Tinker Tom to activate the Relay Platform.
8 Use the Detonator to Destroy the Institute

The Nuclear Option (Railroad) Walkthrough | Fallout 4 (FO4)|Game8 (12)

9 Speak to Desdemona After
