The game begins with Doctor Eggman turning Tails, Amy Rose, Rouge, and the Master Emerald into cards with his new device. Sonic and Knuckles arrive on the scene, and find out what has happened. Knuckles, bent on saving the Master Emerald, tells Sonic that teamwork is out of the question and that he needs to get to Eggman first. Sonic snickers and says that he likes a good challenge. Meanwhile, Shadow the Hedgehog receives a distress signal from Eggman.
