This content requires the base game Cities: Skylines on Steam in order to play.
Mass Transit is the latest expansion for Cities: Skylines, the award-winning city-building game, and it brings several new systems into play to help citizens traverse their towns in speed and style. Commuters can now get around on the water, up high mountain peaks, and even through the sky thanks to the addition of ferries, monorails, cable cars, and blimps to the game.
Along with new transit service buildings, mass transit hubs where lines can exchange passengers, new scenarios, new landmarks, and new road types, urban planners now have more options than ever to add unique style and personality to their growing cities.
