MSCO is a modification for the game My Summer Car. The development of this mod started in October 2019 with the idea of Nika and Diehy. With the current Closed Beta, you can test and play with your friends through limited functionality. The final goal for this project is to have a fully working mod that can be progressed with friends. Our biggest tasks are implementing Satsuma building and Save progression.
The mod has recently entered a Closed Beta that aims to deliver real progress and updates to the Online experience. We are in no affiliation with My Summer Car or Amistech Games, MSCO is a completely external mod that doesn’t modify or touch any original game files.
MSCO Closed Beta main features
- New auto-updating Launcher
- Minimum of 1 update per month from developer
- Much more optimal online experience
- Player lobby limit of 12
