The mastermind behind the Metal Virus isn't done yet. Sonic writer extraordinaire Ian Flynn brings you the latest elaborate scheme from the Blue Blur's newest nemesis! Dr. Starline is back to his evil antics! But to enact his latest scheme, he'll have to get into an abandoned Eggman base, past an army of badniks! And to do that, he'll need the help of some of Sonic's greatest enemies! Zavok, Mimic, Rough, and Tumble are back and badder than ever! Starline's promised them incredible power, so Sonic and friends had better watch out. That is, if the not-so-good doctor can get these Bad Guys to stop fighting each other and work together.
