About the Game
Sonic & Knuckles locks onto Sonic the Hedgehog 3 or Sonic the Hedgehog 2 via the cartridge's lock-on technology, enabling seamless play through expanded levels and new content. Players control Sonic, the blue hedgehog, or Knuckles, the red echidna with gliding abilities, racing through loop-filled zones to stop Dr. Robotnik's schemes. Each character has unique gameplay mechanics — Sonic focuses on speed and momentum, while Knuckles' climbing and gliding open alternative paths. The lock-on feature was revolutionary, effectively creating a full game compilation and allowing players to experience Sonic 3's story extended with Sonic & Knuckles' new zones and bosses.
