well shadow wants to recovver the secret to his past so you have to get the seven chaos emralds and you can help bad guys and good guys if you help good guys you go to a levvel somwher and if you help dark you go to a difrent levell but tou could decide to go by your self and get the chaos emrald and go strait thru the game so if you go helphero,dark,ornormalyoul go to a difrent level so buy it is fun but kind of hard give it a try
