Resources are all the materials and ingredients needed for building objects and crafting items. Survivors can find raw materials working in different tasks, either from natural sources (mines, debris, trees...) or buildings like the wheat farm. More complex materials such as boards or weapon parts need to be crafted, and then there are some materials which can only be obtained as mission loot, such as ectoplasm.
Raw Materials, as their name suggests, are resources that players can harvest from nodes they have created in the base map - nodes such as farms and mines. These resources are either created from scratch (in the case of farms) or are collected from nodes that have a little amount of resource to them. In most such cases, the player has the option to replenish the nodes by various means, such as planting trees or using the Geologist Station.
One step above Raw Materials you can find Manufactured Materials - resources that can only, or primarily, only be crafted by the various facilities in your camp. Sometimes these resources can be traded for or found in various locations as salvage, but for the most part, you will need to create these materials yourself.
Scavenge Materials Edit
Scavenge Materials, again as their name suggests, are resources that cannot be gathered or crafted at all. Instead, these materials can only be found in the wide game world, either by slaughtering certain demons or by conducting missions in specific locations that are rich with this material.
