Liberate the Cult Outpost
You’ll find the Copperhead Rail Yard just to the north of the Hope County Clinic, begin the approach from the north of the Rail Yard, atop a small shed. You’ll be able to use the binoculars to tag the enemies ahead before sneaking back down the hill, past the first alarm and enter the building.
From the entrance, take out the first cultist on the raised platform before heading towards the first alarm and dispatching the cultist on guard, taking care to hide his body after. Wait for one more cultist to approach near the warehouse and take him out from below the ledge to his left (move his body immediately to avoid been seen).
Now take the ladder up in the warehouse to the roof and eliminate the Marksman lurking there. Continue along the roof to spot a single cultist on a walkway, take him out with a silenced weapon. Drop down onto the ground and sneak to the south using the trains in order to get behind the first cultist at the back.
Dispatch him and then proceed to get behind the next two cultists, both of whom should have their backs to you in order for you to eliminate them and liberate the outpost.
