About MESOZOIKUM

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
