Turn 10 Studios has released a demo for Forza 4, the next installment into their successful driving simulator franchise. It's not available on Xbox Live.
The demo is available for people with a Gold account and is 1.27GB in size. It will enable you to drive around the Bernese Alps in numerous cars such as the Subaru WRX STI and 2011 Ferrari 599 GTO.
The full version of Forza 4 will be released on the 14th of October, with Turn 10 hoping it will go on to exceed sales of the previous iterations.
