Amy Rose uses the "Ring of Acorns" to make herself older (like her Dreamcast counterpart) so she can accompany Sonic and the Freedom Fighters to the "Hidden City of the Ancients". It is a journey of discovery that will lead the heroes to the startling new world depicted in Dreamcast's Sonic Adventure game! "Land Fall" In the second story: Knuckles really has his hands full as he has to deal with the damage caused last issue by the wretched Robotnik and his horrid horde of Shadowbots, after having descended upon the Floating Island. It's all part of Robotnik's quest to find "Perfect Chaos" - a hibernating dragon-like monster made of living water. In order to revive it, Robotnik needs a major power source. Having his evil eyes set on the Floating Island's "Master Emerald" - he ends up destroying a portion of the Chaos Chamber and its surrounding land mass to get it!
