Paradox Interactive has revealed the second expansion for Cities: Skylines, called Snowfall.

The Snowfall expansion will introduce an all-new in-game weather system as well as an in-game temperature reading. Cosmetic weather, which is composed of rain and fog, will be added to Cities: Skylines later this year as a free update in addition to other features that will be announced soon.

Players will face new challenges, such as ensuring their city’s infrastructure can handle seasonal heating demands and ensuring roads stay clear when snow starts falling. New snowplow services will play an integral role in preventing traffic from suffering a standstill, while new all-weather trams and expanded public transit options can help residents and visitors make their way around your winter wonderland.

Here’s everything the Snowfall expansion will include so far:

• Rain and fog for existing maps, plus a new “Winter” map theme with snow and all of its challenges
• Expanded public transportation options, including easier management of existing lines – and Trams, a new system demanded by fans
• Cold weather increases demands for electricity, unless new water-based heat systems are in place
• Build a snowplow depot to keep traffic flowing during winter weather, and employ new road maintenance systems to keep your streets in shape
• New Chirps: #yeahthereare
