Sky Sanctuary is the third stage in Sonic Generations for the PC, PS3, and Xbox 360. It is a remake of Sky Sanctuary Zone from Sonic & Knuckles. The stage has the bouncy clouds and teleporter beams like the original, as well as new elements such as shadowy indoor sections and indigo Missile Eggrobos. The rotating platforms from the original have been given a Dragon Road-style twist with missing sections, and the antigravity top from Marble Garden Zone has been imported to this later stage of S3&K. This level is very platforming-heavy, even in the Modern Act, and has a good deal of bottomless pits than most of the other stages in Generations. During the stage, as in 1994, the Death Egg can be seen raising into the sky in the background.
The Sonics make their way to Sky Sanctuary directly after unfreezing Amy Rose at Chemical Plant. Knuckles the Echidna is unfrozen after completing Acts 1 and 2 of this zone, and remarks that "it's good to have my sanctuary back".
As in Sonic 3 & Knuckles the Death Egg appears in the background in both modern and classic acts .
In the Hub Sky Sanctuary has two vines , a fact that in the manual of instructions of Sonic & Knuckles it says that Knuckles loves grapes. These vines also appear in the level, especially in the modern .
