sonic2 I have almost completed sonic rush adventure im on the last level with the deep core or something along the lines it where i have to defeat the dr egg man twins i think! its solid im stuck and i can't find hidden island 15 i have all the sol and chaos emerald and 8 medals and i have almost got all the missions done the story line though is brill and its a big shock when you find blaze and when you find marine again its a great game though its better than sonic rush because the sequel is always better and i haven't used any cheats! nobody is on wi-fi anymore so its not that great!!!
