A NeoForge Minecraft mod built around nuclear technology, fusing Tech, RPG, and Exploration into one experience.
Tech — From Bronze to Nuclear Fission
A massive material system: 86 pure metals (base metals, scattered rare metals, lanthanides, actinides), 28 alloys (from bronze to Zircaloy cladding), and 8 fuel rod types — each with plate/dust/nugget/block variants. The centerpiece is the multiblock reactor with full heat simulation, OBJ rendering, and real-time temperature data via Jade/WTHIT. Crawl from the copper age straight into the nuclear age.
Survival — Radiation & Toxin
The world fights back. Exposure to radiation zones builds up radiation levels; hostile biomes and creatures inflict toxin accumulation. Counter them with Potassium Iodide (anti-radiation), Prussian Blue (detox), and DTPA injections. In combat, inject Adrenaline or OEC Combat Stimulant for burst stats — but watch out for the withdrawal penalty when they wear off.
RPG Growth — You Become Stronger
The built-in PlayerStats system tracks 9 visible attributes: Health, Stamina, Strength, Toughness, Endurance, Heat/Cold/Toxin Resistance, and Stamina Cost Reduction — plus hidden radiation/toxin values. Sprint, jump, kill mobs, and break blocks to accumulate growth, permanently raising your caps over time. The stamina system replaces vanilla hunger as your core action resource, adding real strategic depth to combat and traversal.
Exploration-Driven Progression
Scattered rare metals, lanthanides, and actinides are distributed across the world, pushing you outward to discover rarer ores and unlock the next tier of the tech tree.
And the ceiling is not now. I want to explore the limits of Minecraft and your computer.
