As a city grows, new population milestones will arise that unlock new services, buildings, zones, and areas for the city as well as giving extra cash.

  • New milestones allow you to add new services to your city. When you unlock a new service, you are also given access to a basic building of that type. At later milestones you can unlock new buildings for those services. Usually new buildings provide you with more effective means of managing your city.
  • New zones include higher density residential and commercial zones and office zones. Zoning Specializations can alter the types of buildings in a zone.
  • Unique buildings include various significant buildings, each with separate unlocking requirements and benefits. Monuments are special unique buildings that are unlocked at the last milestone.
  • When a new area is unlocked, you can choose to buy one of the adjacent areas in the area view to expand your city. Some of the areas can have water areas, highways, and/or natural resources. You can have a total of nine areas unlocked by the end of the game, but this could be increased to a total of 25 areas or even 81 areas with Steam Workshop modifications.

List of milestones[edit | edit source]

The population requirement to reach a milestone varies depending on the map selected. The exact formula is currently unknown, but it depends on the flatness of and amount of water on tiles in the central 25 with a Manhattan distance of 3 or less from the start square (including the start square itself).
