The Great Expansion
by Hyper Mods
The Great Expansion is a NeoForge tech and magic mod for 1.21.1 that adds machines, alloys, new ores and a set of tools, weapons and armor.
What it does
Its progression centers on machines and advanced crafting. An Induction Furnace smelts with electricity at high temperature, a Pressure Cooker handles high-pressure crafting and chemical processing, and a Propane Generator produces power from processed fuels. Crude oil can be converted into gasoline, diesel and propane, and Filler Machine Frames and Steel Frames serve as the building blocks for large industrial layouts.
The mod introduces new ores and metals to feed that chain: Bauxite for aluminum, Cassiterite for tin, Galena for lead, Ilmenite for titanium, Cinnabar for mercury, and the Cryonite, Aqualith and Permafrost ores. Titanium and Aqualith tools and full armor sets are added, along with a Steel Hammer and lead arrows. The mod is available for NeoForge only. It can run on a client or a server, and neither side needs it. The license is All rights reserved, so the code is not open source.
