"After the war between the Resistance and the Eggman Empire, the rookie veteran Spectrum The Hedgehog, and his ever-growing band of friends and allies, set out for new adventures. As this new generation of heroes rises up to defend their world though, a new generation of villains rises up too, and "Team Spectrum" soon enters into a deadly rivalry with a daring cult that might decide the fate of the known cosmos itself."
