Challenging space-colony sim. Guide generations of colonists, raise and educate them, manage resources, and ensure food supply. Maintain a breathable atmosphere, tackle pollution, and refine materials to build essential structures. Terraform planet and build ecosystem to make it your new home.
Welcome to a challenging colony simulation game set on a distant planet.
Starting with a small group of colonists, you're tasked to mine resources, refine materials, build structures, and innovate with new technologies. Across generations and centuries, you'll expand your settlement into a thriving civilization and terraform the planet to make it your new home.
Colonists are born, educated, work, retire, and die. Over generations, their needs may evolve and dedication may diminish.

Nothing simply disappears. Every bit of material transforms into something new. Resources follow their own cycles, involving production, consumption, and recycling.

Transform barren soil into fertile farmland using materials from your surroundings. Melt ice for water, use the water to grow food, and then purify it for reuse. Balance these elements and watch your colony thrive on the food you produce.

Convert exhaled carbon dioxide back into oxygen for your colonists. Tackle industrial pollution and manage various gases. As your base expands, maintaining atmospheric pressure becomes essential.

Begin with mining ores and minerals, refine them into advanced materials essential for constructing buildings and crafting items. With each step, transform raw resources into the foundational elements of your expanding colony.

Transform the planet's surface to make it habitable by managing temperature control, ecosystem growth, and water resources. Create a breathable atmosphere and turn the planet into your new home.
See you underground!
