Sonic the Hedgehog 2
Death Egg Zone

Death Egg Zone (デスエッグ[1] Desueggu?, lit. "Death Egg") is the eleventh and final Zone in Sonic the Hedgehog 2. It takes place onboard Dr. Robotnik's iconic Death Egg satellite.



After Wing Fortress Zone's destruction and hitching a ride to space aboard Robotnik's fleeing rocket, Sonic makes his way inside the battle station, only to be greeted by Mecha Sonic while Dr. Robotnik watches from the background. After defeating the robot, Sonic then chases down the scientist across the Death Egg, who flees to his new Death Egg Robot and the Doctor confronts Sonic.

Once the mech is taken down, the Death Egg begins to explode and Sonic manages to survive by hurling himself out of an airlock into space. Looking like the end for Sonic as he descends through the stratosphere of his world, Tails appears and catches Sonic on the Tornado, thus ending the game, but if the player has all seven Chaos Emeralds, Sonic instead safely flies beside the Tornado as Super Sonic.


Death Egg Zone is a single Act Zone which does not feature any hazards and has a simple straightforward path to the Zone's two bosses; starting with Mecha Sonic and then the Death Egg Robot. Unique to this Zone, the Zone does not feature any Rings at all so the player must avoid getting hit by the bosses' attacks.



Mecha Sonic

Mecha Sonic is perhaps the Sonic robot which bears the most resemblance to Sonic apart from being a little taller and has a silver-colored scheme. Mecha Sonic has many different attacks that are mostly similar to Sonic's, such as the turbo-dash and spin-jump. However, the most challenging move of Mecha Sonic's is his jump-and-spike-launch-attack. The best way of avoiding this is to kill the robot before he gets a chance to use it; spin dashing Mecha Sonic the moment his jet-boots touch the decking. Sonic can hit him 4 times in one bout if one times it right. Then accrue another 4 hits (for a total of 8) to the robot's head to defeat him.

Once Mecha Sonic is vanquished, Sonic enters a quick chase scene with Dr. Robotnik before he jumps into the final boss robot.

Death Egg Robot

The final boss of Sonic the Hedgehog 2.

The Death Egg Robot is the second boss of the Zone as well as the final boss of the entire game. It begins to walk towards the player while moving its spiked hands back and forth. Afterwards, it flies offscreen into the air in an attempt to stomp on the player. After landing, it will then launch its arms like rockets. In addition, it can launch a pair of grenades which almost guarantee death should the player get behind the Death Egg Robot. The boss is defeated after twelve hits.


  • This zone is an inspiration to E.G.G. Station Zone from Sonic the Hedgehog 4: Episode I, even sharing a revamped final boss.
  • Like the previous game's Final Zone, the player has to defeat the bosses with no Rings.
  • This Zone recycles the tileset used in Chemical Plant Zone, with an altered background and palette.
  • In the 2013 re-release of Sonic the Hedgehog 2, if the player "clears" Death Egg Zone with a Signpost or Capsule placed in Debug Mode, the player is then taken to Hidden Palace Zone.
  • In the Simon Wai prototype, a very early version of this Zone's BGM plays whenever the player obtains 100 Rings instead of the usual 1-Up theme, which is due to the song's placement being where the 1-up sound was in the first Sonic the Hedgehog game as Sonic the Hedgehog 2 is built from it.
  • Tails and Knuckles have a slightly longer drop from the Death Egg to Earth before being caught by the Tornado than Sonic in their respective endings. This is because the Tornado was programmed to arrive at a specific part of the ending tune, and the ending omits the illustrations at the beginning that show the Tornado taking off when playing as Tails or Knuckles, opting to immediately cut to Tails or Knuckles falling to Earth.
  • Robotnik is meant to have a laughing animation whenever Sonic takes a hit from Mecha Sonic. However, this is not seen during normal gameplay since Sonic has no Rings, therefore taking a hit and dying freezes all gameplay. The laughing animation can be seen if Sonic is given Rings through Debug Mode, or playing the game on the Nintendo 3DS with "Ring Keeper Mode" enabled.
