Sonic and Knuckles

Developer: Sega Technical Institute

Sonic & Knuckles is a high-speed side-scrolling platformer for the Sega Mega Drive / Genesis that doubles as a capstone to the classic Sonic era. Players dash through intricately designed zones, using momentum, loops and precise platforming to race past hazards and tackle multi-stage boss fights. The cartridge’s standout features let you play as Knuckles with unique climbing and gliding mechanics, giving stages fresh exploration and secret paths. Tight controls, memorable music, and variable difficulty reward skill and replayability—especially when paired with Sonic 3 for expanded routes—making it a nostalgic, fast-paced challenge for retro fans.
