⚠️ Eco v0.14 is coming — the next major update reworks upgrade modules, so some of these numbers will change. They reflect the current version. What’s changing →
  • Simpler tiers: the 1–4 tiered upgrades become a single Basic / Advanced / Modern upgrade each.
  • Permanent upgrades: a module placed in a workstation is permanent — no more swapping lower tiers out as you progress.
  • Power transitions: a module can change a station’s power type/draw (e.g. a Modern upgrade moves a sawmill from mechanical to electrical power).
  • Talent-integrated: modules now use the same bonus/talent system — any talent benefit (power, labor cost, recipe unlocks) can come from a module.
  • Cheaper to upgrade: with the multi-tier parts gone, fully upgrading a workstation costs significantly less.

We’ll update this calculator shortly after the update releases.

Notes

Fiberglass is an advanced composite material produced from a crafting recipe, serving as a key ingredient in modern tools, weapons, and construction components such as Servos, Fiber Reinforced Concrete, and a wide range of upgraded equipment. It sits in the mid-to-late game materials tier, requiring industrial infrastructure like a suitable crafting station and power to produce efficiently. Stocking fiberglass in town stores is a practical milestone, as it enables other players to craft high-tier items without needing to set up their own composite production chain.
