Quick answer: Treat each technology as part of a chain: research unlocks a recipe or build option, mastery can gate the action, and the correct work area must have room for the station or extension.

What is confirmed

  • The official screenshot confirms a dedicated Building technology view.
  • Metallurgy contains Bronze Works, Bronze Melting, Iron Forge and later smithing unlocks.
  • Research points use different colors and the point cap is 999 by design.
  • Start from the object you need and trace backward to its recipe, station and prerequisite technology.
  • Spend for the current objective before opening unrelated branches.
  • After research, check the relevant building desk or compatible host station; an unlock does not automatically place the object.

What not to assume

Third-party point costs are version-sensitive. Verify them against the current in-game node before publishing a fixed build order.
