Sonic and Tails team up for a classic handheld adventure in Sonic Chaos for the Sega Game Gear, known as Sonic & Tails in Japan. When Dr. Robotnik steals the Red Chaos Emerald, plunging South Island into chaos, it's up to Sonic and Tails to retrieve it. Play as either the speedy Sonic or the flying Tails, each with their unique abilities, as you navigate through vibrant zones, collect rings, and battle Badniks. Sonic Chaos was the first Game Gear Sonic title to feature Tails as a playable character, offering fans a new way to experience portable Sonic fun.
