Mars Base Alley

Mars Base Alley is a cozy city-builder about creating the perfect little corner of humanity on the red planet.

After a bumpy landing on Mars, you arrive at a quiet crater with a simple request from Mayor Roark: help turn this empty stretch of dust into a place people can truly call home. Instead of one grand city plan, the Mayor invites a handful of designers to each build and care for their own alley, slowly shaping Mars Base City together.

Each alley grows at its own pace. You’ll place buildings, manage resources, keep settlers comfortable, and gently respond to Martian challenges like dust storms, power hiccups, and changing needs. There’s no rush—just thoughtful decisions, small optimizations, and watching your alley come to life.

As the colony fills with warmth and activity, your alley is quietly evaluated alongside the others. Happy settlers, smooth resource flow, and a well-designed space all matter. With care and creativity, you may earn Mayor Roark’s special recognition and be crowned Champion Designer of Mars Base Alley.

On a once-lonely world, you’ll build a cozy future for humanity—one alley at a time.
