Mesozoikum

Mesozoikum is a satirical nuclear management game in which you run an aging power plant where profit matters more than safety. You oversee neutron density, temperature, cooling systems, power grids and personnel, while deciding how to handle the truth when things go wrong.

Manage the reactor

Control rods, cooling loops, emergency power, venting and boric acid systems. You can operate systems manually or automatically, balancing stability, output and risk in real time. Decisions have cascading consequences for the reactor.

Handle crises

Respond to incidents, system failures and core meltdowns, deciding when to intervene and when to let events escalate. Not every disaster ends the game; some are simply accounted for. A minor mistake can become an incident, ignored warnings can lead to a partial meltdown, and a severe failure may require you to build a sarcophagus.

Choices and consequences

You weigh safety against profit, personnel against expenses, and honesty against trust. Each decision affects reactor stability, public perception and your final balance sheet. The game’s political satire includes sarcastic awards for catastrophes, absurd dialogue with safety regulators, and a world where loyalty is praised and consequences are negotiable.

Expand the plant

Build fire brigades, generators, enrichment facilities and control rooms. You can upgrade systems to prevent failures or survive them as the reactor grows more complex and dangerous.

Possible outcomes

The game can end in stable operation, controlled catastrophe or total systemic collapse. Awards include the Golden Comrade Star for “Hero of the Controlled Catastrophe,” the Silver Comrade Star for “Profit Despite Fireball,” and the Bronze Comrade Star for “Avoided Unnecessary Catastrophes.”
