A gameplay trailer for Sonic the Hedgehog 4: Episode 2 has been released, and posted by Gamespot. Episode 2 takes place following the events of Episode I, where Metal Sonic has returned to form an alliance with Dr. Eggman, and Sonic and Tails must team up and race four new Zones in order to put an end to their evil plans. Players will be able to play co-op online or locally. Still no exact date, but it releases sometime this spring for XBL, PSN, iOS, and Android. Thanks, AGB.
