- You may be looking for Death Egg in general.
Death Egg Zone is a scrapped zone that would have appeared on the Sega Saturn cancelled video game, Sonic X-treme. It is the sixth and final zone of Sonic X-treme. Based off of the Death Egg Zone that appeared on both Sonic the Hedgehog 2 and Sonic & Knuckles, this stage would have been the final zone in Sonic X-treme. Gravitational-pull parts of the level are present in Death Egg Zone. According to concept art, it was meant to have a global time limit between act to reach the final boss.
Death Egg was going to have three acts: "Factory Robo", "Proving Grounds" and "Megabase Control", but concept art shows that it was meant to have five acts, with the fourth being a secret and the fifth is the boss battle with a "core" hubworld where you can select the acts.
According to the footage given about the Death Egg Zone, there is actually no sign of the Death Egg anywhere, unless the stage itself is below the actual Death Egg.
- In the PackageX leak of levels & textures, it was found that the Death Egg Zone had about 12-14 levels related to it.
