As a sequel to the original numbered Sonic the Hedgehog games from the earlier console, Sonic 4 was a well overdue addition to the franchise that brings the classic side-scroll platforming, but also is not just one standard game but spread over several episodes. Episode I was released all the way back in October 2010 and after far too a long time, Dimps and the Sonic Team are finally releasing Episode II. This is the latest trailer for the game, and as the name suggests highlights the inclusion of Tails as a playable character.
This game is due for release in May 2012 for the XBox Live Arcade, Playstation Network, iOS, Android, Windows Phone 7 and PC.
