All of the Emerald Powers in Sonic Superstars have been revealed, as well as details on its Special Stages.
As with previous 2D Sonic games, Chaos Emeralds are acquired in the game’s Special Stages. Now, each Emerald will grant players a special ability to be used throughout the zones.
The idea behind this was to give players smaller rewards, where in previous games a reward was given only once all Chaos Emeralds are acquired (usually Super Sonic).
