You got to go to the final stage after fighting shadow and silver including robots then you get emeralds and then you go to the final stage and that's it I've done it 3 tover a year ago
@sonicgmance221: I think they're talking about how to use Super Sonic within the actual levels, because I've unlocked the ability. ---- @sonic808: Have you bought the Super Sonic ability from the shop yet? If not, go to the shop and buy it, then add it to one of your ability sets and use that set. When you're playing a level you have to collect 50 rings (maybe 100, I can't remember) then you have to press a certain button to go Super Sonic. The ability makes you invinible and all that but in some levels it can prove more of an annoyance than helpful.over a year ago
