Colossal Order was founded in 2009 with the dream of creating a city-building game. Starting with a small team, we focused on the mass transit simulator, Cities in Motion, taking what we learned with us into its sequel, Cities in Motion 2.

In 2015, they realized their dream with the release of our first city-builder, Cities: Skylines, with support continuing all the way to 2023 and the release of its sequel, Cities: Skylines II.
