Sonic Generations demo races to XBL, PSN

It’s Sonic’s 20th birthday, everyone! To celebrate, Sega’s giving both Xbox 360 and PS3 owners a taste of the hedgehog’s latest speedy adventure, Sonic Generations.

A demo of the title, due out in full later this year, is available via Xbox Live Marketplace and the PlayStation Store now, weighing in at 652 and 664MB, respectively.

Looks like it’ll be available for 20 days only though, so best grab it in a hurry. It’ll be pulled on July 12.
