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.
