About MWC Editor

A community-built tool for the next generation of Finnish car building survival.

The Mission

My Winter Car (the sequel to the legendary My Summer Car) introduces new mechanics, a new car (the Rivett), and harsher survival elements.

This editor exists not to ruin the game, but to save your time. Whether you lost your 100-hour save to a physics glitch, fell through the map, or just don't have time to grind for new spark plugs, MWC Editor is your digital toolbox.

Open Source

This project is 100% open source. We believe in transparency, especially when dealing with your precious save files.
