Under the very unassuming name of patch 1.1.0f1, Cities: Skylines 2 is getting something quite big. The sequel now has the modding, map editing, and code modding support that made its predecessor such a sprawling success.

Only time will tell if community energy can help restore some of the energy that has been dispersed by the fraught launch of Cities: Skylines 2 (C:S2). The project of relatively small developer Colossal Order arrived in October 2023 with performance issues and a lack of content compared to its predecessor. Some of that content perception stemmed from the game's lack of modding support, which had contributed to entire aspects of the original game not yet available in the sequel.

When Ars interviewed Colossal Order CEO Mariina Hallikainen in December, she said that modding support was the thing she was most looking forward to arriving. Modding support was intended to be available at launch, but the challenges of building the new game's technical base, amid many other technical issues, pushed it back, along with console releases.
