Sonic has finally reached the Egg Fortress Zone, the new mega-base of Dr. Eggman. Deadly traps and powerful Badniks are found at every twist and turn, but it's nothing a super Hedgehog can't handle! Once inside the main core of the structure, Eggman activates a new device which turns back time and forces Sonic to backtrack to the entrance. Awaiting him there is Eggman's most powerful mech to date, and it will take all of Sonic's abilities to fight this monster...
