Metallurgy+ aims to improve the game by making metal smelting and production more varied and interesting. Focus is on abstracting real-world processes and enriching gameplay by providing different production chains with their own trade-offs. (And it removes iron plates.)

Please note that this mod is currently in an alpha state. This means this mod can and will change in the future. Savegame compatibility between version will not be guaranteed.

It is recommended to start a new game with this mod. Updates to this mod or the game might break your saves, so do not get attached to them. Do not add it to any game that you wish to keep as it can not be easily removed afterwards.

Current features:

  • Reworked iron production chain.
    • No more iron plates, everything uses steel plates.
    • New machines, the blast furnace isn't used for everything.
    • New products like charcoal and coke.
    • New and changed research nodes, partially to improve game progression, partially to make the new content visible.
  • There is more than one way to produce steel, with different trade-offs, if I've done the balancing right.
  • Somewhat useful side products.
  • Tutorial goals are fully adapted for the mod.

Possible future features:

  • More uses for side products.
  • Better integration into the other production chains.
  • Reworks of other metal production chains, especially the older ones like e.g. copper.
