Sonic the Hedgehog 4 community manager Aaron Webber recently did a quick video walkthrough for some of the levels in Episode 1.
With only days left till the downloadable episode uncurls its way onto WiiWare, PSN and XBox Live Arcade, SEGA have been busy pimping the new title - which is aiming to be the "true" and direct sequel to the fan-favourite Genesis/Mega Drive foursome that ended with Sonic 3 and Knuckles over 16 years ago.
Webber is also promising a teaser silhouette at the end of the first part to suggest what's coming up in the next. We're thinking...Tails "Miles" Prower, perhaps?
At the end are snippets from the totally-unrellated Duke Nukem Forever. Ah, that's where he was all this time - making Sonic the Hedgehog 4. Right...
