⚠️ 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.

Shale

Shale

A soft rock, with few potential uses. Shale is a sedimentary rock formed by thin layers of compacted clay or mud.

Notes

Shale is a soft sedimentary rock mined with a basic pickaxe, serving as a versatile early-game building and crafting ingredient. It is essential for producing Mortared Stone to construct tier-1 rooms and for crafting Geology Research Papers to unlock new specialties. Stockpiling shale ensures a steady supply for both town infrastructure and research progression.
