Science has a concept of metallic hydrogen, which is a compressed gas with a pressure similar to that found at the center of gas giants. Unlike ordinary liquids, this material has the properties of degenerate matter, with a large reserve of energy. Despite its liquid phase, its viscosity and inertia make it visually similar to the fuel of the future, but with enormous internal energy for future technologies. Metal hydrogen is created from tungsten ore on Vulcan and synthesized using a centrifuge. This mod introduces a high-tier engine powered by Metallic Hydrogen. It is a modified version of the original Space Age platform engine with custom fuel logic, adjusted animations, and balanced performance for late-game challenges.
