Miniopolis is an announced PC city-building sandbox from Radiangames, with a Steam store page live and a demo scheduled for release soon. The game drops zoning, infrastructure development, and resident management in favor of free-form building tools.
Miniopolis surfaced on September 11, 2026, when Radiangames posted gameplay footage to the studio's official X account showing a minimalist city builder built around voxel-style tools. Players can change the size and shape of every building, stretching, denting, and joining square structures to their neighbors, and can place water tanks and plants as accessories. At that point the studio said the Steam store page would open early the following week and that a demo was scheduled.
Five days later, on September 16, Radiangames officially announced the game and published the Steam store page. The announcement locked in the platform as PC on Steam and described Miniopolis as a city-building sandbox rather than a management game. Players shape buildings freely with intuitive tools, working from six types of basic blocks plus auxiliary pieces such as lighting, trees, and parking lots, and can control weather, indoor lighting, and depth of field.
The throughline across both stories is what Miniopolis removes. There is no zoning, no infrastructure development, and no resident management, the parts that usually drive a city builder. Radiangames is pitching the buildings themselves as the editable material, and the store page went up ahead of the demo. The demo is still only described as scheduled for release soon; no date has been given.
