Sonic the Hedgehog turns 20 today and SEGA is celebrating by releasing a demo for Sonic Generations on Xbox Live and PSN. The demo will include the 2 acts of Greenhill Zone. Act 1 will be using Classic Sonic and Act 2 will be for Modern Sonic.
It's the same demo that was playable at this year's E3 show floor so for those of you lucky enough to have been there, this is the same game. The demo will only be available until July 12 so grab it while you can.
Also announced for PSN is a 20th Anniversary Bundle. The bundle Sonic the Hedgehog, Sonic the Hedgehog 2, Sonic the Hedgehog 4: Episode 1, Sonic Adventure and a Sonic 4 Dynamic Theme. The bundle costs $19.99.
