The Undercity: Last Light

A city beneath the world. A future in your hands.
The Undercity: Last Light is a single-player colony management game in 2D pixel art. Light the beacon, welcome survivors and carve a home into the rock. What begins as a small refuge can become a sprawling underground city—with production to keep running, people to look after and a story that leads deeper into the earth.Dig, build and keep it all connected

Turn excavated chambers into farms, kitchens, workshops and homes. Link raw materials to finished goods, keep supplies moving and choose when to expand or upgrade. A second workshop is useful only when it has the workers, materials and routes to do its job.Every shift is a choice

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 times
Prepare 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.

Explore the Thermal Rift, Fungal Sea and Resonant Archive, each with its own machinery, hazards and story. Complete Grand Projects, send teams on surface expeditions and pursue a Civilization Project. The current Early Access campaign has a finale; you can keep managing your colony afterward.

Built with player feedback. Early Access updates focus on balance, clarity, stability and the decisions that make each colony feel different. English and Turkish interface text and subtitles are available.
