GameInformer: "Tails spent his early Genesis days as Sonic’s co-op partner. Dedicated player twos across the world used the sidekick’s flight ability and invincibility to help the hedgehog exact revenge on Dr. Robotnik. Unfortunately, the two-tailed fox was always left choking on Sonic’s dust when things picked up speed, thus 2D Sonic co-op never felt truly balanced. For Sonic 4: Episode II, Sega attempts to create a compelling two-player experience whether you’re controlling Sonic or Tails. Thanks to the characters’ shared vitality and some egregious levels and boss fights, the end result is an awkward mess."
