Berley Lake Ambush Camp is a Lost Lake camp northwest of the Berley Lake Infestation. Clear it for Iron Mike's Trust and the Proximity Bomb recipe in its bunker, one of the best Horde tools in the game.
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. Camps like this string wire traps across nearby roads to knock riders off their bikes, so come in slowly.
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. Read the bunker's recipe to learn the Proximity Bomb.
Proximity bombs let you mine a chokepoint before a Horde fight. Clear this camp before you take on the big Lost Lake and Highway 97 Hordes.
Deerborn Ambush Camp
Deerborn Ambush Camp is a Marauder camp in the cliffs east of Lost Lake, south of Sherman's Camp. Its Marauders ambush supply runs on the Santiam Highway, and clearing it pays Iron Mike's Camp.
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.
Bare Bay Ambush Camp
Bare Bay Ambush Camp sits in the far south of Highway 97, south of the Chemult College NERO Checkpoint. Like Aspen Butte it pays 5,000 XP and 2,750 Diamond Lake Trust, so it is worth the long ride.
