Build humanity’s first home on Mars. Mine resources in first person, construct life-sustaining domes, grow lush vegetation, and launch rockets to reconnect with Earth in this immersive colony-building simulator.
Terraforming Mars Simulator
SteamMars Colony Simulator is a first-person colony-building simulation where you land on a hostile red planet and turn it into a thriving human settlement: one structure, one resource vein, one decision at a time.
You don’t command from above. You build it with your own hands.
Step outside your habitat and work the Martian surface directly.
• Mine iron, ice, rare minerals, and regolith • Operate drills, extractors, and processing machines • Physically place and assemble structures in the world • Watch your colony grow from scattered modules to a living city
Every expansion is something you personally constructed.
Mars is dead, until you change that.
• Build sealed domes with breathable atmospheres • Grow crops, trees, and lush vegetation under glass • Manage power, oxygen, water, and food production • Balance efficiency with aesthetics as your colony expands
Turn an empty planet into a place people can live in, not just survive.
Mars is far from home… but not unreachable.
• Construct launch pads and communication arrays • Send rockets to Earth to unlock new technology • Receive blueprints, supplies, and narrative events • Expand beyond survival into long-term colonization
Your colony becomes a bridge between two worlds.
Mars Colony Simulator focuses on immersion, scale, and progression rather than micromanagement spreadsheets.
• First-person gameplay from landing to megastructures • Realistic sci-fi inspired by near-future space tech • Calm, atmospheric pacing with moments of tension • Designed for players who love Satisfactory, Subnautica, and space sims
Mars won’t terraform itself. You are the pioneer. The engineer. The colony.
Welcome to Mars.
