  • Byproducts: nearly every recipe now leaves waste behind, so recipe pages list byproducts alongside ingredients.
  • Garbage & recycling: waste sorts from mixed garbage down to pure materials, and can be recycled back into stock.
  • Pollution has four kinds: acid rain, chemical, soil and heavy mineral, each settling into the ground differently. Pollution guide →
  • Modules reworked: upgrades are now Basic / Advanced / Modern / Specialty, one per slot, driving the same bonus system as talents. Module guide →
  • Fresh water: machines need it — water drawn from the ocean has to be desalinated first.

Notes

Spruce Log is a softwood block and fuel source harvested from Spruce trees. It serves as a foundational early-game material, used in a wide range of recipes from basic building components like Boards and Campfires to more advanced items like Composite Lumber and the Carpentry Table. As a fuel, it provides 4,000 units of energy, making it a useful early heat source for campfires and kilns. A practical tip is to stockpile Spruce Logs early, as they are a key ingredient for producing Charcoal, a more efficient fuel that is critical for advancing through the smelting and metalworking stages.
