Snowfall brings a "flurry of new weather-related features" to Cities: Skylines this month.
In January, Paradox Interactive announced a weather-based expansion for Cities: Skylines, titled Snowfall. Snowfall will bring an in-game weather system, along with the issues traditionally associated with such weather. Rain and fog are added for existing maps, along with a new winter-themed map, and additional public transportation options, including Trams, a "new system demanded by fans."
In a press release today, Paradox gave the forecasted date for Snowfall's arrival: February 18. From the press release:
"In Snowfall, a new in-game temperature system will keep mayor-players on their toes. When the snow starts to fall, the roads will need to be kept clear, and buildings will need to be heated. Residents will also have the chance to visit new winter parks and landmarks available in Snowfall, along with an all-new tram system to get them across town in all sorts of weather. These features will arrive alongside free updates for all Cities: Skylines players when Snowfall launches on February 18."
The expansion will release on Windows, Mac, and Linux PCs, and will cost $12.99.
