Industry plus
Industry Plus expands the industry technology tree by a slight amount, adding small upgrades to boost production and resource extraction.
Works with any mod that dose not modify the Industrial technology category.
Some mods might replace the Indutrial technology category but not actually modify it, make sure that this mod is above that mod in the playlist section of the Paradox Launcher.
