Sonic & Knuckles

Sonic & Knuckles is a 1994 platform game developed by Sega Technical Institute and published by Sega for the Sega Genesis. Players control Sonic the Hedgehog or Knuckles the Echidna in their quests to save Angel Island; Sonic tries to stop Doctor Robotnik from re-launching his orbital weapon, the Death Egg, while Knuckles scuffles with Robotnik's minion, EggRobo. Like previous Sonic games, players traverse side-scrolling levels at high speeds while collecting rings and defeating enemies. Sega Technical Institute developed Sonic & Knuckles simultaneously alongside its predecessor, Sonic the Hedgehog 3 (1994); they were planned as a single game until time constraints and cartridge costs forced the developers to split it.
