A new addition to Cities: Skylines 2 gameplay is Signature Buildings, unique zone buildings that provide buffs to their surrounding areas depending on the nature of their construction and placement. In a bid to better “personalize” the city-sim, Cities: Skylines 2 players can use Signature Buildings to help add a dash of style to a growing city, especially since more Signature Buildings are unlocked based on a city’s overall progress pertaining to Milestones, citizen Happiness levels, or Zoned areas.
