Mad Tracks is a fun arcade racer, featuring toy cars and has already achieved demo downloads in excess of 400,000 since February.

"Most people who played this game are telling us their life is better now and that they have more friends," says Thomas Leinekugel, VP project manager at Load Inc.

The full game features a total of 46 challenges (23 mini-games and 23 races), 12 cars, and a fully featured multiplayer mode with support for network and split screen play. The PC version is available now, complete with demo, and an Xbox 360 version for Live Arcade is also planned.

There's also a promo running for the PC version which gives a 20% discount to the first 500 people to order the game at the $14.99 price, when using the code "Get mad".
