Death Egg (Sonic Forces)

Death Egg is the twenty-second stage in Sonic Forces, and the sixth Classic Sonic stage in the game. This stage is a re-imagining of the Death Egg Zone from Sonic & Knuckles on the Sega Mega Drive.

Located onboard the Death Egg, this stage is set close to the space station's power generator. During the events of the game, Classic Sonic came here to destroy the Death Egg, and, by extension, the Phantom Ruby's power supply.

Story
With the Death Egg's weapons system shut down by Sonic from the Chemical Plant, Classic Sonic gets ready to board the Death Egg so he can destroy it and cut off the power supply powering the Eggman Empire's Phantom Ruby.

Between Tails´ optimism and Vector's skepticism about the success rate of this mission, Classic Sonic gets onboard the Death Egg, only to discover that its defense systems are still online, much to the surprise of Knuckles. Figuring that the Death Egg's crew have switched over to auxiliary power, Tails is certain that Classic Sonic can handle this nonetheless. Along the way, the Death Egg's shifting gravity makes Vector feel disorientated. Regardless, Classic Sonic manages to cause such a ruckus that the Death Egg begins to crumble. With that in mind, Classic Sonic escapes the Death Egg before it explodes.

Gameplay
The main gimmick of Death Egg is the Conveyor Belts. Among the Conveyor Belts found in this stage, some of them move along the floor, creating a plaform the player must stay on at all costs. Stationary Egg Pawns may also stand on Conveyor Belts, leaving them to automatically move towards Classic Sonic, which makes it more dangerous for the player to walk on Conveyor Belts. Other local gimmicks include plaforms that change positions when Classic Sonic steps on them, and the Ring Shooters (which are deployed three seconds after touching them). There are also the important particle-lined surfaces that blink in and out of existence in intervals, which can be used by as solid plaforms or bridges. In places with particle-bridges, one bridge that leads to one place may get replaced with another that leads to a different place while the first one blinks out, thereby forming branching paths. In addition, there are some stage sections with shifts in gravity that cause Classic Sonic to walk on the ceiling.

The main obstacle encountered in Death Egg are red-hot glowing panels. These panels can be set on the walls, ceiling or floor, and touching them will cause Classic Sonic to take damage. However, they will also destroy any enemy that makes contact with them. There are also laser cannons on the walls that charge up for a few seconds before firing straight-moving laser blast that inflict damage upon contact.

Being a Classic Sonic stage, Death Egg is played entirely from a 2.5D perspective, and include Item Boxes for Classic Sonic to utilize. In addition, there are invisible Springs that only show themselves when the player steps on them.
