Atmospheric Expansion

# Atmospheric Expansion An add‑on for Modern Industrialization that turns your world into a survival gauntlet—no air, no mercy. ## Description The entire Overworld, Nether, and End have gone airless. To survive, you must design, build, and power Atmosphere Generators that force oxygen back into selected areas. Expand your life‑support network with pipes, then explore, automate, and industrialize without choking. ## Features ### Thermolitic Reactor The Thermolytic Reactor applies intense heat-driven decomposition to smelt and refine a wide range of ores and raw materials in one continuous process. By harnessing thermolytic reactions, it not only yields purified metals and minerals but also captures and vents high-purity oxygen as a valuable byproduct—perfect for powering your factories and breathing life back into hostile, airless worlds. ### Atmosphere Generator The Atmosphere Generator employs high‑pressure separation and compressor technology to establish stable, breathable air pockets in oxygen‑deprived areas, delivering pure oxygen within a fixed radius. Seamlessly integrated with your power grid, it continuously sustains life‑support coverage, enabling safe expansion and exploration in hostile, airless environments. ### Oxygen Tank The Wearable Oxygen Tank is a portable life‑support unit that straps directly to your armor, storing and dispensing pressurized oxygen on the move. Engineered for durability and efficiency, it can be refilled inside your Atmosphere Generators and delivers a steady supply of breathable air wherever your adventures take you. ### Mob Spawning Spawn mechanics have been overhauled for greater challenge and immersion: hostile mobs now only spawn below set altitudes, forcing you to light and secure deeper caverns, while passive animals can appear even in dark areas
