Sonic, the world's fastest hedgehog, continues his adventures in this
fourth installment of the Sonic The Hedgehog series! This time, he
buddies up with his former enemy, Knuckles the Echidna in order to
defeat the evil Dr. Eggman (AKA Dr. Robotnik). At the end of Sonic The
Hedgehog 3, Dr. Eggman’s ultimate orbital weapon for global domination,
the Death Egg, was badly damaged in an epic battle with Sonic. The Death
Egg, losing power rapidly, hurtled back down to the planet below and
crash-landed on the mysterious Angel Island again. Now Sonic and
Knuckles must put a stop to Dr. Eggman once and for all, before Eggman
and his no-good-niks get the chance to find the secret to Angel Island’s
floating power, the Master Emerald.
