The Modular Race Track Kit designed by and for game developers. It's designed from the ground up with mobile optimization in mind, so it can be used within mobile phone projects, tablet projects and or PC/Mac. The kit itself is completed, so there is no gamble waiting for it to be delivered at a future date. Backers will get the download link to this project and all bonuses as soon as I receive the email.

And a bonus perk with the kit:
All (16) Low Poly Vehicles including (3) LODs for each.
