Cities: Skylines 2's new developer releases debut patch focused on death

Iceflake Studios, which replaced Colossal Order at the end of 2025, has issued its first update for Cities: Skylines 2. Rather than introducing sweeping new systems, the debut patch zeroes in on how citizens die. The update changes mortality across the game, making citizens expire around the clock and removing immortality in easy mode—previously, about 80% of them never died of old age.

Other adjustments include an 80% reduction in bicycle trips, new UI icons for roundabouts, cul-de-sacs, road maintenance depots and pollution types, an updated onboarding tutorial, and less aggressive terraforming tools. The patch also brings graphical fixes such as improved shadow rendering, snow support for decal-based lots, and fog that responds to weather, and it turns autosave on by default after two years, four months and a developer change.
