This week, Turbo Sliders Unlimited marks one year since its full release on Steam!

There have already been numerous updates, with the latest, v1.03, bringing even more features and improvements.

But Turbo Sliders Unlimited isn’t just about updates — it’s about what the community is creating. Players have built an incredible variety of custom levels, vehicles, campaigns, and even whole new game modes! The creativity is Unlimited, keeping the action fresh every time you play.
