Cities: Skylines II · Progression system
Milestones and Expansion Points
Milestones advance through Expansion Points earned from city growth and actions, and award Development Points alongside other rewards and unlocks.
How it works
Paradox describes 20 milestones, from Tiny Village to Megapolis. Expansion Points accrue passively 16 times during an in-game day in response to population and happiness increases, and actively after actions such as placing or upgrading a service building, constructing a signature building, or expanding the road network. Milestones grant a mix of monetary rewards, Development Points, Expansion Permits, and access to services, policies, management options, and zone types.
