The Doomsday Zone is the eighth and final Zone of Sonic & Knuckles (the fourteenth Zone of Sonic the Hedgehog 3 & Knuckles). Only Sonic may play the level normally, and only after collecting at least 7 Chaos Emeralds (i.e. only in Super or Hyper form). He transforms into his Super form (Hyper if the player has collected all of the Super Emeralds) as the Death Egg is falling apart to catch Dr. Eggman as he tries to escape with the Master Emerald.


The Doomsday Zone is set in asteroid-filled space above the planet. The player must fly through the asteroid belt and fight Eggman to recover the Master Emerald and foil his plans again.

Because Super Sonic must play this stage, the player starts out with 50 Rings instead of 0, and loses Rings at the traditional Super rate of one per second. There are extra Rings along the course of the level, but if the player's Ring total drops to 0, Sonic will fall out of Super form and lose a life. When the player is down to 10 Rings, the music tempo will increase to raise tension and warn the player to collect Rings. This tempo increase does not occur in Sonic Jam.

To defeat the first form of the Final Weapon, the player must drive the missiles it fires into the cockpit of the ship. After 8 hits, Eggman returns in a flying mecha, resembling the Death Egg Robot boss from Sonic the Hedgehog 2. The player should keep their Ring supply up by hanging back when needed, but when they feel comfortable with their Ring total, they should hold Right and hit any of the face buttons to begin ramming into Eggman. Hitting his bombs and the asteroids slows the player down. After 8 hits, the Master Emerald is freed and Eggman is beaten again.

Also, if one looks back at the fight Sonic and Knuckles had at Hidden Palace Zone, they will see a mural hanging on the wall. It displays Super Sonic and one of Eggman's spaceships in outer space. This method of foreshadowing is also used in Sonic Adventure, where Sonic reaches the depths of the Lost World and finds a mural displaying Perfect Chaos.
