Build a Civilization on Mars Simulator

4.2
(874)

240 million kilometers from home. No backup plan. No second chances.

You’ve just landed on the Red Planet with 50 colonists, limited supplies, and the weight of humanity’s future on your shoulders. The unforgiving Martian environment doesn’t care about your Earth-bound assumptions, dust storms that last months, temperatures that freeze CO2, and radiation that kills slowly but surely.

Every decision cascades into life or death. Prioritize oxygen over food? Risk expansion over stability? Trust the brilliant engineer who’s showing signs of psychological breakdown? Your colonists look to you for answers, but

Mars follows its own brutal logic.
You’ll face impossible choices: who gets the last medical supplies, whether to abandon a failing outpost, how to maintain hope when Earth is just a pale dot in an alien sky. Leadership here isn’t about charisma—it’s about keeping humans alive and sane in humanity’s most hostile frontier.

Can you build more than shelters? Can you build a society worth living in?

Mars is waiting. Your species’ future depends on what you build there.
