While I feel like all of these expansions are slightly too pricey, I still must commend the Cities: Skylines developers for their continued support. Despite releasing a damn good game over two years ago they have continuously added more and more content to it. Sometimes its silly and fairly questionable stuff like extra music, other times its ridiculously awesome stuff like blimps and giant monorails, but there's always something new and interesting to toy around with.

With all of that in mind, it really shouldn't come as too much of a surprise to hear that Cities: Skylines will be going eco-friendly later this year, all thanks to the newly announced Green Cities expansion. You can expect to see a variety of new structures, parks, electric cars, alternative service buildings, eco-friendly stores, and the list goes on. If you would like a quick peek at what all of this looks like in-game, you'll find the recently posted teaser trailer right below. Have a look:

What might come as a surprise, however, is that this expansion will be accompanied by a significant free content update. The details are still a bit shaky, but the free update will include electric cars, road modding, changes to noise pollution, more beautification options in the form of parks and trees, as well as a variety of other features.

To learn just a little bit more I would recommend you head over to the Paradox website, but don't expect to find much as Paradox likes to keep us in the dark right up until release. And finally, here's a brief list of features that arrived with the announcement, just in case you want a quick overview:

Story to Story, Building to Building, Street to Street: New Eco-Friendly Buildings, New specialization buildings, new alternative service buildings, new unique buildings, electric cars, new parks -- 350 new assets in all giving a unique new look to Cities: Skylines
