After picking this side-mission up from the hunting shack in the southern part of the valley beneath the village, we’ll be tasked with locating and destroying four drones that are flying around the area. Shooting them with any weapon will disable them and you’ll be able to locate them by moving to the green pulses on the map and scanning the air until you find them.
The first drone is located just north of the quest giver and can be picked off immediately after commencing the side-mission.
The second drone can be found near the cliff wall to the east of the southern guard tower and the hunting shack. This area is inhabited by a leopard so be very careful and use your Poison Arrows or heavier weapons to dispatch it quickly if it attacks.
At the base of the wall, you’ll find a Coin Cache [03/09] . At the top of the westernmost hunting platform you’ll find a Hanging Rabbit [Hung out to Dry 05/06]. Near one of the rocky formations leading to a hunting platform directly west of the hunting shack there is a Survival Cache [08/20] .
The third and fourth Drones can be found flying near the treetops just outside of the two caves that we previously explored in the cliff side on the western side of the valley.
Once you have shot down all four drones, you’ll be close to the northern end of the valley. Return to the Remnant village and hand in the ‘Defensive Strategy’ side-mission.
Return back through the village until you see the ruin on the left. If you look down from the cliff top between this building and the house to the south, you’ll see a ledge below that you can drop to. This houses one of the Survival Caches we looted earlier. Use the climbable wall to shortcut back down to the valley floor.
Return to the ‘Surveillance Disruption’ and hand in the completed quest for a reward.
Leave the immediate area and then return inside to speak with the ally by the hunting shack once again. She’ll offer you a new side-mission ‘ A Hearty Meal ’.
