We’re excited to release the biggest update Underground Garage has seen so far—built with your feedback and powered by your continued support. This one’s all about you and for YOU <3.

Thanks for being part of the journey—leaving us feedback in the Steam forums, joining our beta tests, and helping us make the game better every step of the way. We couldn’t have done it without you.

⚠️ IMPORTANT! ⚠️

In this version, we've introduced extensive changes to improve stability, performance, enable modding, and add new vehicles. Unfortunately, this comes with compatibility issues for your old save files. You can still load them and will retain your prestige, money, progress, and cars - but these will be the new versions of the vehicles, not your exact same cars, as we've completely rebuilt the vehicle handling code from the ground up.

We recommend starting fresh, as playing on old saves may cause bugs and issues. We apologize for the inconvenience - we hope you understand that this is an Early Access game, and based on your feedback, we've completely overhauled the entire vehicle system. This has also resulted in much improved driving mechanics and tuning options.

Happy tuning! ~ The Underground Garage Team
