Mobius... a planet that was previously a war-torn hellscape for many decades. By the efforts of Sally Acorn, and the equally Noble Freedom Fighters, the empire of the infamous Ivo "Eggman" Robotnik would be collapsed, ending the war. And for 15 years, it stayed that way... until now. Snively Robotnik, apprentice and nephew of Ivo Robotnik, has came out of hiding and is now threatening the planet of Mobius with his new creations, that are now even tougher than the ones from Ivo. Now a new generation of Heroes and Villains shall rise up during the conquest of Mobius.
