Hard Vulcanus


Tweaks to Vulcanus. Demolishers are more numerous, the map is smaller, molten lava and metals have restrictions on how they can be piped, Acid neutralisation produces cooler steam, coal liquefaction is nerfed, and mining tungsten requires lubricant. For full details, see the mod portal page. Other dependencies are intended to be included, but all are listed as optional for maximum customizability. To get the full experience, enable this mod via the Space Age: Hard Mode modpack.
