From the PDA Mill website:
Flux Challenge is our upcoming 3D racing game. This unique racer revolves around a world of magnetic-levitation tunnels. While originally designed for mass transportation, it soon spawned many underground ship-racing circuits and eventually became one of the largest international championship sports. Take control of one of these magilev ships, and become the international champion!
