Edge of Reality Zone

Edge of Reality Zone (現実感の端ゾーン, Genjitsu-kan no hashi zōn) is the penultimate Zone in Sonic Dimensions. It's the only Zone that lacks a boss, and can only be played during the Final Zone scenario, meaning it can't be played without collecting all of the Chaos and Sol Emeralds.

The Astral Nebula has been destoryed, and as such, the energy of the Life Orbs began to go haywire, breaking the dimension into fragments. It's the biggest, longest and hardest stage in the game, as the player has to master each character's special abilities and be able to have very good reflexes to get through the stage. With a lot of hazards and objects that can cause instant death, the player will have to be very cautious and quick.

Appearance
Edge of Reality consists of the dimension becoming broken. As such, this stage is made out of sections of the original levels of the game, but they all underwent a dimension break. The stages taken are based off of layouts that are in the actual stages, but they can be merged with other level sections, or warped completely to be harder. Each location takes the appearance of their dimension break counterparts, however, each stage has a purple tint. Some stages tend to have additional visual changes, such as the Relic Ruin machinery being cracked.
