Keep your radio tuned to the appropriate frequency. You’ll often hear radio broadcasts mentioning sightings of Unknowns in specific locations.

Next, walk up to the cliff of North Valley Galleria. You will find the bodies of two settlers and a note from Courtney, who is one of the missing settlers. The note reveals that a group of ghouls attacked Courtney and other hunters. She also mentions that she saw a signal booster at the end of the abandoned Tronic Store. You will find a Mister Gutsy bot guarding the corpses, who will nudge you to find the signal booster.

2. Find the Signal Booster
Location: Harpers Ferry / North of Valley Galleria

The holotapes in this area reveal that the remaining settlers were directed to seek refuge in the sewers beneath the Dyer Chemical plant.
5. Enter the Sewers in Dyer Chemical Plant
Location: Dyer Chemical Plant

After reaching the Dyer Chemical Plant, you need to find the entrance to the sewers. You will find it alongside the river in the area, which is on the west side of the facility.

Before entering this area, you can put on a radiation suit to protect yourself from additional damage.
After you are inside the sewers, you need to proceed straight and take the first left turn that appears. Now, you will finally enter the pipe, take the first right, and then turn left. Continue to walk straight until you come across a flight of stairs.
You will now come across a door, open it, and enter the area. You need to take another right turn from the gallery which will lead you to another staircase, walk down the stairs and you will finally find Lucy Harwick’s dead body behind the machines.
