Play the role of Sonic once again and join in with his friends to stop another one of Dr. Robotnik's plan to rule the earth in Sonic the Hedgehog 3! Also known simply as Sonic 3, the game begins shortly after the second game. In this game, Dr. Robotnik's massive space station known as the Death Egg, crash-landed on a floating landmass. There the story gets even more interesting when Dr. Robotnik successfully duped Knuckles and tricked him into fighting the protagonist Sonic and his friend Tails. Gameplay-wise, the game starts with either Sonic or Tails (depending on the player you choose). You must take control of the protagonist and go on a 2D side-scrolling adventure to stop Dr. Robotnik and win against Knuckles.
