Horse Creek Ambush Camp is a Cascade story job northeast of Copeland's Camp. Squatters put a sniper on the cliffs over the Horse Creek trail. Clear it to keep Copeland's supply runs safe.
Find the sniper first and use rocks and trees as cover on the climb. Scout from cover with Survival Vision, then take quiet kills with the crossbow or a suppressed gun. If it goes loud, fall back to a doorway and let them come to you.
Killing everyone isn't enough: find the bunker hatch and read the map inside to clear the camp. The bunker then works as a fast travel point and a bed to sleep in.
Cascade Radio Tower Ambush Camp
Cascade Radio Tower Ambush Camp is the first ambush camp you see, during the story mission No Starving Patriots. It sits north of the Little Bear NERO Checkpoint and pays Copeland's Camp.
Jefferson Rail Tunnel Ambush Camp
Jefferson Rail Tunnel Ambush Camp is a Cascade story job at an old rail tunnel. Clear it for Copeland's Trust and the Superior Club recipe in the bunker, a strong early melee upgrade.
Ambush Camp
Ambush Camps are hostile survivor camps you clear for the Ambush Camp Hunter storyline. There are 14 across the map, each paying XP, Trust and credits to a nearby camp, and each bunker becomes a fast travel point.
Aspen Butte Ambush Camp
Aspen Butte Ambush Camp is a Highway 97 camp northwest of the Chemult Community College NERO Checkpoint. It pays 5,000 XP, the joint best of any ambush camp, and clearing it stops the traps on the roads around it.
