They thought they had defeated Dr. Robotnik for good. But it seems Snively, in an act of desperation, has brought a NEW Robotnik from another world, this one calling himself Dr. Eggman.
Now Sonic will have to find and reform the Freedom Fighters to battle this new, overly jovial and energetic Eggman in his "game".
So it seem I was too impatient to go through 4 storylines, and 10+ chapter to get to the Adventure and beyond stuff.... So I decided (Why not just do them both at the same time)
So yeah... naturally the next page will include a "recap" of everything that has, and will happen in the other comic... Spoilery fun
