Sonic & SEGA All-Stars Racing

For this achievement you will firstly have to purchase all the remaining characters (marked with an * , Total of $220000) I will explain how to successfully perform each all-star move for each character as a few people (including myself) have had trouble, I will point out that the three troublesome characters are AiAi, Amigo and Shadow.

To obtain an all-star power up you must be struggling in the race (in 8th and away from "the pack") so my suggestion is to setup a single race with 2 laps on beginner difficulty on the first track (Whale lagoon) and at the start of the race let everyone else drive off, once they are upto the first corner you can start but just drive slowly, but dont get too far behind. You should hopefully get the all-star power up on your first lap if not the first power up on your second, once got use it (ill go into each proper use next)
