Having teased on their Twitter yesterday that something new for Cities Skylines was coming, today Paradox have revealed their second expansion to their popular city-building game: Cities Skylines – Snowfall.

As their previous expansion added a day and night cycle to the game, Snowfall will be adding a weather system to the game allowing for rain and snow as well as a new temperature reading that will have residents huddling up for warmth. It’ll add a new mechanic to the game – making sure that your city is able to be kept warm enough during the times when the weather outside is terrible and keeping roads clear when the snow starts to pile up.

The expansion will also add some new transportation options to the game, including trams which were a much demanded fan-favourite to be implemented into the game next. Managing transport routes has also been made easier to do and a snowplow service can be called upon to clear roads that have a build up of snow upon them. There will also be wintery new parks and other attractions added to help draw your residents and tourists from miles around, as well as a new Chirp #yeahthereare.

Some of the cosmetic weathers such as rain and fog will be added to the original game free of charge in an update around the time that Snowfall releases along with other yet-to-be-announced features, and the expansion will be coming to Windows, Mac and Linux computers sometime later this year.
