Assign specialists, balance day and night work, train the next generation and give tired or injured workers time to recover. Families, aging and colony needs shape the workforce you can rely on. Clear resource readouts, room inspections and contextual guidance help you understand what is holding the colony back.Keep the colony together through hard timesPrepare for earthquakes, breakdowns and changing hardships. Respond to requests and opportunities, weigh costs against benefits, and decide what needs attention first. Repairs, recovery and new construction compete for the same people and resources. Your decisions shape how the colony grows.Go deeper. Discover what lies beyond.
