Great news, Forza fans. As promised, Microsoft has released a playable demo for Turn 10′s Forza Motorsport 3 on Xbox LIVE today. The demo allows you to try out the following cars on the game’s Camino Viejo track: Porsche #80 Flying Lizard 911 GT3-RSR on Camino Viejo Full Circuit, Audi R8 V10 5.2 FSI quattro, Ferrari California, Mitsubishi Evo X, and the Mini Cooper JCW.

That’s not the only demo treat for today, though. The Brutal Legend demo, which was exclusive to GameStop for the past week, is now up for grabs on the Xbox LIVE Marketplace as well. You’ll get a small taste of Eddie Riggs, his axe, his guitar, and his badass awesome lines voiced by the great Jack Black.

Head over to Xbox LIVE now and give these demos a download.
