Sega is sending out a second demo for Sonic Generations, its multi-year mascot mishmash coming to PC, PlayStation 3 and Xbox 360 on November 1. The new demo, which should be available on Xbox Live Marketplace starting tomorrow (followed by a North American PSN version on October 25), revisits the checkerboard loops of Green Hill Zone, this time with a "modern Sonic" component.

The classic version of the level (see: slightly rotund Sonic) will also be available in this demo, just in case you missed it in the first round back in June.
