Walkthrough
  1. 1
    Meet your Courser contact at Bunker Hill. You can attempt a hard speech check for extra grenades. The Courser will give you "Recall Codes" for the Synths.
  2. 2
    The battle begins with Railroad Fighters, Institute Synths, and Brotherhood of Steel soldiers fighting each other. The Brotherhood is the most powerful force, utilizing Power Armor, Gatling Lasers, Miniguns, and Vertibirds. Synths warp in at street corners.

    Navigate the streets, avoiding or fighting enemies as needed.
  5. 5
    Enter Bunker Hill from the east entrance and make your way to the obelisk.

    In the basement, follow the linear path until the room opens up.

    After shutting down the Synths, the Courser will thank you and warp them away.
