Sonic the Hedgehog 2 Addendum

The development for Sonic 2 is undoubtedly a well-documented piece of Sonic history, showcasing the process of how the Sega Genesis/Mega Drive classic came to be from its co-development between Sonic Team and Sega Technical Institute. A combination of scrapped content, additional quality-of-life tweaks and bonuses result in the Sonic 2 you know and love getting better than ever.

While cruising over the ocean in his antique biplane, the Tornado, Sonic notices a small island particularly lush with greenery. He flies down for a bit of vacation time, closely followed by an unseen figure that lands on the opposite end of the island... The tiny resort turns out to be West Side Island, which, as the folklore goes, was once the home of a flourishing civilization. The people of the island utilized the power of seven mysterious stones for the advancement of their society. However, their prosperity lead to avarice, which did not sit well with the gods. The displeased deities reclaimed the stones and sealed them away.

After a few days on the island, it occurs to Sonic that he's being followed. His pursuer is a young fox with two tails who, upon being discovered, dashes into the shade of a nearby tree. Sonic ignores him and zooms off, but the fox whirls his two tails like a propeller and follows the blue stranger at full speed. Sonic is impressed both with the fox's tenacity and his ability to keep up, so he decides to let him tag along. He learns that his new companion is named Miles Prower, though the animals of the island call him "Tails" due to his two tails.

Early one afternoon, Tails discovers the Tornado sitting on a beach. Being fascinated by all things mechanical, the young fox eagerly runs up to the machine for a thorough investigation, but shyly pulls back when he spots Sonic snoozing in the shade of a wing. His awkward moment is interrupted by a huge explosion from the island's interior. Sonic snaps up to see the forest ablaze and robots scouring the area. It doesn't take the blue hero three guesses to figure out who's behind the disruption: Dr. Eggman, who had discreetly followed Sonic onto West Side Island, is now tearing the place apart in search of the seven Chaos Emeralds. He needs fuel for his Death Egg, a planet-sized space station with unthinkable power. Sonic and Tails take off to locate the Emeralds before Eggman and squash his evil ambition once more.
