A member of the Sonic Retro forums found that several Sonic 4 Episode II screenshots leaked on the Xbox Live Marketplace. These screenshots depict what appears to be cooperative gameplay with Sonic and Tails. Two of the zones are reminiscent of Sonic 2′s Aquatic Ruin – along with Sonic 3‘s Marble Garden motives – and Oil Ocean. The other two are a carnival and a ice/water themed level. Sonic 2′s special stage also makes a return. In some of the screenshots what appears to be Little Planet from Sonic CD can also be seen, which confirms that the story of Episode II will be linked to CD’s plot.
Additionally, the Xbox Live Marketplace revealed that the title will support local and online co-operative gameplay, something the franchise has lacked this entire console generation. All of this information has been pulled from the Xbox Live Marketplace since. It was previously confirmed by SEGA PR Ken Balough that Sonic the Hedgehog 4 Episode II will feature a new physics engine.
