The latest expansion for last year’s excellent city building sim, Cities: Skylines, will be launching on February 18. The previously announced Cities Skylines: Snowfall is due out on February 18, releasing simultaneously for all computers running Windows, Mac, and Linux. it will cost $12.99.

Like the previous expansion, Snowfall is far more than a simple color swap, or even more than just the inclusion of weather- entirely new systems, which derive from the in game weather, such keeping roads clear, arranging for heating for buildings (and the auxiliary systems necessary, like power), and new all-weather public transport, are all introduced to the game to add even more layers to the simulation than it had before.

In addition to all this, new winter themed landmarks and buildings will also be made available to players as part of Snowfall. This, plus multiple free updates, are all coming to Cities: Skylines later this month, so fans of the hit city sim should be well served.

The excellent city simulator that launched last year, Cities: Skylines, will be getting a brand new expansion soon, its second one- it’s called Snowfall, and like the first expansion, which added night time to the day, Snowfall adds weather. And as with the first expansion, weather changes will be more than just palette swaps- they will affect the entire game and how it plays, with new city departments dedicated to dealing with weather, citizens needing new heating facilities, roads needing maintenance utilities for extreme weather conditions, and new weather themed landmarks.

Basically, Snowfall takes an already incredibly in depth and nuanced city building simulator, and makes it even more nuanced. I can’t complain about it, especially since the depth of Cities: Skylines, and the potential for emergent gameplay that it offers, is my favorite thing about the game.
