"Cities: Skylines" will make other city builders green with envy, as its new "Green Cities" downloadable content (DLC) has just been released.

Developer Colossal Order and publisher Paradox Interactive have introduced the "Green Cities" DLC for their city building simulator on Oct. 19 and have since then garnered generally positive reviews from players. The DLC now holds an overall review rating of 80 percent positive based on 128 reviews at the moment. More reviews are expected to be counted as time goes by.

"Green Cities," as its name implies, introduces another layer of management in the city building simulator. The DLC will add new ways for players to improve the eco-friendliness of their cities and towns. As much as 350 new in-game assets have been included in the update. These assets will take the form of facilities, eco-friendly buildings, organic shops, electric vehicles, new services, and recreational structures.

Specifically, the new structures include geothermal power plants, ocean thermal energy conversion plants, solar updraft towers, eco water outlets, eco water treatment plants, recycling centers, floating garbage collectors, community pools, sports hall and gymnasiums, yoga gardens, community schools, institute of creative arts, modern technology institutes, and biofuel bus depots.

Along with the new assets, a massive selection of new visual options is also provided for players. Those who want to replace the usual grey cityscape with something more lively can now do so. The goal of the DLC is to reduce pollution or abolish it altogether by offering alternatives to the gas-run factories, like renewable power and eco-friendly industry.

New specialized districts are also available for the Residential, Commercial, and Industrial city sectors, significantly changing the building styles and pollution output of those within the district. Houses in the residential area, for example, will now have solar panels on roofs instead of the usual concrete or metal ones. The Noise and Environmental pollution metrics of the game are also getting a revamp to accommodate the more eco-friendly assets.

"Cities: Skylines - Green Cities" is out now and is available for $12.99. The base game is available for $30 on Steam.
