This document summarizes CriticalCity, a real-life urban transformation game that aims to improve cities from the bottom up through citizen collaboration on missions. It works by giving citizens points for completing missions that involve bringing art to streets, meeting people, and discovering hidden areas of cities. The startup plans to become self-sustaining through a freemium model, user donations, and selling services to city administrations. It has created a beta version and community in Milan, won awards, and partnered with game designers to develop new game mechanics and missions focused on improving specific urban areas and expanding internationally.
