A gret game
In multiplayer you can olay different modes you can play the running mode and there are many stages and many characters to choose (Sonic ,Shadow ,Metal sonic ,Amy Rose) in battle mode you need to destroy the other player"s machine with guns and power-ups thera are many stages and charactera too (Doctor Eggman ,Tails ,Chao and Dark chao) in the finding emeralds mode there are many stages and characters too (Knuckles the echinda ,rouge the bat ,a strang thing and cream) and the chao battle mode ,the chao race. So in my opinion this game have a lot of modes so you cant get tired of rhis game.
And thats all Masterbonus at your service bye
