⚠️ 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

Oil Drilling is a Tier 4 specialty used for harvesting and refining oil to produce essential industrial materials like Gasoline, Petroleum, and Synthetic Rubber. It requires the Scientist prerequisite to unlock and is leveled up by crafting related recipes. Because specialties cost an escalating number of stars to learn, players should prioritize this niche and trade with others to maintain a balanced economy.
