Paradox Interactive and developer Colossal Order have announced a new expansion Cities: Skylines, titled Mass Transit.

The new expansion naturally brings with it new forms of mass transportation in the game, enabling players to provide new ways for their citizens to traverse their sprawling metropolises. Featured above, you can view a new trailer for the expansion.

There’s also new transit service buildings, new scenarios, new landmarks, new road types, and mass transit hubs where passengers can exchange between various forms of transportation.

Here’s a rundown of key features, via Paradox:

• Sick Transit, Glorious Money: Add a wealth of new transit options to your city, and add wealth to your city’s income! Let your citizens get across town in ferries, blimps, cable cars, and monorails!
• Orderly Hub, Bub: New mass transit hubs can bring all of your services together, letting citizens change rail lines in one building, or hop from the bus onto the ferry, or even find their way through a sprawling monorail-train-metro station.
• Become a Roads Scholar: Explore a set of new challenge scenarios focused on solving traffic problems and adding new transit systems. New road types, bridges and canals adds variety to your city, and new ways to solve its challenges. Become an expert in traffic flow, and then use that knowledge to improve your city!
• New Hats for Chirper: NEW. HATS. FOR CHIRPER. (and also new unique buildings, policies and achievements. But HATS!)

The expansion will come alongside a free update to the game’s vanilla release, as Paradox has done with previous expansions. The update brings with it traffic-management features inspired by mods like emergency vehicles overtaking roads, extended public transport budgets, and more. You’ll also be able to name roads, finally.

Cities: Skylines – Mass Transit is set to release sometime this year for PC, Mac and Linux. No word for an Xbox One release, as that version has yet to ship.
