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
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.

[h3]⚠️ IMPORTANT!⚠️[/h3]
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

Hi Underground Garage fans,

We’ve got a bit of unfortunate news to share — the April Patch will need to be postponed to May.

Why the delay? We’re committed to delivering top-tier quality, and right now, we can’t guarantee the level of polish we strive for. We’d rather take the time to get things right than release something that doesn’t meet your expectations — or ours.

We truly appreciate your support, so we’re offering Underground Garage at a special 30% discount.

Here’s a quick reminder of what’s coming in the upcoming May Patch:

• New cars
  
• New engines
  
• More missions
  
• Modding support
  
• A new map
  
• AI street races
  

Check out the video below for a sneak peek at how AI racing is shaping up!
[previewyoutube][/previewyoutube]Keep in mind this is still a work in progress, so some bugs may be visible.

Thanks for your patience and continued support — we can’t wait to show you what’s next!

All the Best,
The Underground Garage Team
