Sonic the Hedgehog 4 Episode 2 will see Sonic and Tails once again exploring new lands to stop Eggman's nefarious plans and defeat Metal Sonic. The first batch of screenshots show the heroic duo racing through a snowy carnival, watery ruins (which look a bit like Sonic 2's Aquatic Ruin Zone), and a desert oil field.
Co-op play is returning in Episode 2, allowing a friend to join the adventure over the internet or local multiplayer. Tails players can not only help Sonic reach out-of-the-way places, the two buddies team up to pull off new attacks such as a giant spin dash. Tails is also around to help gather rings in the Sonic 2-style special stages.
Sonic the Hegehog 4 Episode 2 releases later this year for Xbox LIVE Arcade, PlayStation Network, and mobile devices.
