Thermonuclear Expansion Addon transforms late-game survival into a realistic, hardcore nuclear tech grind. Instead of simple “mega TNT,” players must mine uranium (from redstone), refine it, build risky reactors for plutonium transmutation, craft hazmat gear, and assemble atomic bombs or thermonuclear missiles. No experimental features required, but reactors can melt down/explode if not waterlogged, and materials cause radiation damage.
