Where can I find other materials that are used for crafting, like batteries?

A lot of materials in the game such as Batteries, Aluminum Sheets, Wiring, etc. can only be salvaged on locations such as a Plane Crash, Car Accident, or through the Trader. Also, check other areas of the map and click them to see where items have a high loot drop rate.

Other Materials like bricks need to be made using a Stone Cutter. Check your Blueprint section to see which furniture can be made that produces other materials.

Tip:

In order to maximize gathering resources, focus on leveling up your character in order to unlock better backpacks. Here are the materials you'll need:

Military Backpack

10 Dense Fabric

5 Leather
