There are a variety of building materials which can be scrapped from objects found all over the map. The most common materials are Wood, Metal, and Cloth which are the staples for constructing a makeshift base.
Tools are an important requirement when crafting or building a base. Each tool has a purpose and has a limited amount of uses before it no longer works, so keeping on eye on durability is crucial. Some tools are rare and can only be found when salvaging enemy drones.
Salvage a plethora of items and use them to craft a variety of structures or weapons. You can loot materials from buildings, vehicles, or even by scrapping objects, such as furniture, that are spread across the zone. Some items require a specific tool or schematic. All craftable objects are divided into three categories: Basic Structures, Support Structures, and Usable Items/Weapons (consumables).
The inventory menu contains a crafting tab in where you can craft items or buildable objects. It will display which items you can craft (learned recipes), along with the amount of required materials needed (this includes raw materials and tools). You can learn how to build new items by finding blueprints or schematics.
Once you craft a buildable object, such as a structure, you can equip the item and place it anywhere in the environment. Buildable objects are treated as consumables, so they have a one time use once placed and are equipped in the same inventory quick slot.
There are a variety of buildable/placeable objects and structures that you can craft. They range from defensive structures like bunkers, to support structures, like turrets or land mines. Some structures are stronger than others depending on the type of material they are made from. Bellow is a gallery of all the in-game objects you can build and place on the map.
