What is Sphere - Flying Cities?

This single-player survival city builder takes place after an asteroid strikes the moon, leaving Earth's surface uninhabitable. You construct infrastructure, move your flying city, and send drones to gather materials and find survivors. You supply colonists with food, healthcare, and shelter while maintaining power for the city's anti-gravity device and protective shield.

+you like researching technology to improve your colony's efficiency

Not for you if...

−you want to build freely without managing survival threats
