⚠️ 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.

Contracts

Contracts maintain an agreement between two citizens.

A contract is an agreement between two citizens created at a Contract Board. The agreement can have any number of clauses, and specify combinations of work to be performed and compensation to be paid. It is posted by the client citizen, and can be accepted by any valid citizen asynchronously.

Examples of contract include:
- Create a road between two designated points.
- Loan money between two parties with a given interest rate and due date.
- Build a room of given requirements at a specific location.
- Custom requirements described in text, and accepted/rejected by the client upon completion.
