Electrifying, Mines Go Boom – Zoey
Heavenly Gift, Field Kitchen – Chimamanda
Fire Sale – Pierre
Horror Slasher – Dave
The batteries Zoey is looking for is found in a place called Kiwi Camping, a bit farther to the east from your camp. It will be faster (and safer) to reach it via vehicle so bring one as you make your way there. The car batteries are located inside the trailers. After finding them all, you'll have to find two electric cables next. These are located northeast of the camping site. You have to follow the mountain trail on foot to reach it.
Upon reaching the settlement, make your way to the other side of the house and use the crates at the back to reach the wooden ledge above and get inside the fence. You'll find the electric one of the electric cables there as well as workbench. Barge inside the room and kill the suicider inside. Loot the items there. You'll find the cable near the suicider and a recording underneath it as well.
Unbar the door and head outside. Look at the roof of the flooded house nearby to find a lone man. Approach him to trigger another sidequest. (Rescue Stanley). Once done, deliver the items to Zoey to complete the quest.
Mines Go Boom
After completing the sidequest “Electrifying”, talk to Zoey again to start this quest. You have to gather x4 Suicider Meat and x2 Scrap Electronics. There is a suicider that will spawn near the vehicle parking by the Paradise Survival Camp and inside the cavern leading to Pierre's shop. They respawn fairly quickly so you only have to loot different containers and bags for the electronics. They will continue spawning there as long as you have this quest active so use this chance to gather as much suicider meat as you can since these are also required for another team quest.
Head to the beach and your objective will be updated. There will be three spots you need to look for supplies on. Consult your map for the green circles. You need to find water bottles, bandages and food supplies. Refer to the images below to know where these items are located.
After completing Heavenly Gift, Chimamanda will offer this repeatable quest. Just bring her canned food that you can find while exploring to continuously earn experience and cash.
Dave is located above the trailer in Mataka Village. He'll ask you to recover his camera and some batteries. Head to the marked location and enter the abandoned set you passed by earlier.
Once inside, you have to turn off the generator outside. Once turned off, backtrack and open the door. Grab the camera and other loots inside and break the next door open. Kill the undead film crew outside. There's a workbench nearby and the camera battery is located inside the shed beside it. Exit the film set and return to Dave.
You can find Miya in a small camp in the northern part of the village. You have to follow a short cavern to reach it. After receiving the mission, you have to head to the marked areas and find the military supply crates.
The supply crate to the west is found along the rocky cliff to the southwest of the green circle.
The supply crate in the middle of the map is located in the upper trail. You have to climb it using the vines. The crate is located behind the bushes to the west side of the trail.
The supply crate near the marina is found on the roof of the northwest trailer.
After completing “Proximity”, talk to Miya again to start this quest. The biosphere lab can’t be found in this island so set this quest aside and continue doing the other quests first.
