No holds barred street racing, Forza Motosport-style, is ushered in with Forza Horizon, the fifth in the Xbox Forza series, and, from the previews, the first to make the leap from track to road. The teaser features DJs and massive rave-style partying, desert, midways, bikinis, and a whole lotta open road. Microsoft’s Turn 10 Studios has a new partner for this one, UK developer Playground Games. It’s all set to drop in the Fall.
