"Sonic the Hedgehog returns for a full-blown, action-packed adventure through the desolate and unpredictable World of Mubuz, a world dictated by an evil Dragon Lord, Immarius. Upon entering Muboz, Sonic fights an evil power which turns all the inhabitants into dangerous beasts.
* Become Wolf Sonic and fight enemies like never before using rapid combo maneuvers and Ring Energy
* Play as Sonic, Knuckles or Tails through 12 packed stages
* Extensive 2D gameplay brings the old Sonic back home"
Now, there's 3 characters and thats not including wolf sonic because I'm guessing thats just a add-on. ( get an item or a certain amount of coins type thing) Hopefully more characters pop out while playing the game. Most likely we wont be hearing to much more about this game until E3.
