Paradox Interactive announces that winter has come to Cities: Skylines with the release of the Snowfall expansion for the urban planning game. This is accompanied by a new patch to update the base game to version 1.3.0, adding new features, including a map and theme editor to allow modders their own takes on the game. This video unashamedly jokes "the wait is snow-ver" in showing off how the expansion looks, and this forum post has more details on both Snowfall and the new patch. Here's word:

Paradox Interactive, a unique snowflake among publishers, today announced that the newest expansion to Cities: Skylines is now available for aspiring mayor-players everywhere. “Snowfall,” which was released today for players of Cities: Skylines, adds a flurry of weather-related features to the game, along with new transportation options and several new winter attractions to help citizens chill out. A new free patch has also released today, including a new map Theme Editor to allow modders to alter the very fabric of in-game reality. Snowfall is available today on Windows, Mac, and Linux PCs for $12.99.

In Snowfall, the difficulty heats up when the city cools down, thanks to a new in-game temperature reading that will have residents bundling up for warmth when the weather outside is frightful. Cosmetic weather, including rain and fog, has been added to Cities: Skylines as part of a free update. Players who own Snowfall will get to face new challenges such as ensuring that their city infrastructure can handle seasonal heating demands – and, when the snow starts falling, that the roads can stay clear. New snowplow services will be required to prevent traffic from freezing in place, while new all-weather trams and expanded public transit options can help residents and visitors alike get around town – and visit the new winter parks and landmarks available in Snowfall.
