Short description
A satirical nuclear reactor management game about profit, control and the art of the acceptable catastrophe.
About this game
Mesozoikum: Reactor Civilization Profit. Power. Consequences. Take control of an aging nuclear reactor in a world where profit matters more than safety and statistics can always be adjusted . CONTROLLED MELTDOWN is a satirical nuclear management game where you oversee every aspect of a power plant: neutron density, temperature, cooling systems, power grids, personnel — and most importantly, how the truth is handled when things go wrong . A small mistake? → Incident. Ignored warnings? → Partial meltdown. A really bad day? → Build a sarcophagus. As long as the money keeps flowing, everything is… acceptable . ☢️ Core Features 🔧 Deep Reactor Management Control rods, cooling loops, emergency power, venting & boric acid systems Manual and automatic systems with real, cascading consequences Balance stability, output and risk in real time 🚨 Crisis & Disaster Handling Respond to incidents, system failures and core meltdowns Decide when to intervene — and when to let things escalate Not every disaster ends the game… some are just accounted for 🧠 Moral Choices Without Morality Safety vs. profit Personnel vs. expenses Honesty vs. trust Every decision affects reactor stability, public perception and your final balance sheet. ☭ Dark Humor & Political Satire Sarcastic awards for “successful” catastrophes Absurd dialogue with safety regulators A world where loyalty is praised and consequences are negotiable 🏗️ Infrastructure & Expansion Build fire brigades, generators, enrichment facilities and control rooms Upgrade systems to prevent — or survive — failure The reactor grows more complex… and more dangerous 🏁 Multiple Outcomes Stable operation Controlled catastrophe Total systemic collapse 🏅 Awards Golden Comrade Star “Hero of the Controlled Catastrophe.” Silver Comrade Star “Profit Despite Fireball.” Bronze Comrade Star “Avoided Unnecessary Catastrophes.” ⚠️ Disclaimer This game is satire . All depicted disasters, decisions and systems are fictional. Any resemblance to real-world events is purely coincidental. Probably.
