Today, developer Colossal Order and publisher Paradox Interactive announced that Cities: Skylines, which released exactly two years on March 10, 2015, has now sold over 3.5 million copies worldwide. And to commemorate this milestone, Paradox and Colossal Order will be throwing out some free DLC, which will come in the form a a set of three new in-game buildings inspired by Chinese architecture.

Titled “Pearls from the East,” the pack will contain the following three new buildings: a Panda Zoo, a Chinese Temple, and the Shanghai Pearl Tower. According to Paradox, the DLC will be available "soon."

Fredrik Wester, CEO of Paradox Interactive accompanied the announcement with the following:

“From the first day Cities: Skylines was released, it’s been breaking records. The game had our biggest launch in history at the time, selling 250.000 copies in its first 24 hours, and the community has only gotten bigger and more devoted over the last two years. Cities: Skylines perfectly showcases the kind of experiences we’re proud to support at Paradox: a game that people are just as excited to play now as they were two years ago. Happy birthday to Cities: Skylines, congratulations to Colossal Order, and my sincere thanks to all our players. Please follow me on Chirper.”

Mariina Hallikainen, CEO of Colossal Order added:

“It’s fair to say that Cities: Skylines has changed all of our lives at Colossal Order. This is a game we had all been working on and dreaming about creating for years. Seeing how many people have rallied around it, and seeing the incredible community sharing their cities and mods has been so rewarding and inspiring. On behalf of our entire team, thank you so much to all of our players for your ongoing support!”

Cities: Skylines is available for $29.99 USD on PC, Mac, and Linux. It is also scheduled to arrive on Xbox One sometime during Q2 2017. Additionally, just two weeks ago, Paradox announced a new expansion for the game titled Mass Transit.
