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. Act 1 begins in a similar way to the original stage, passing in the outer parts of the sanctuary, with dazzling views and anti-gravitational tops, ending also in a similar way to the original stage, the towers falling this time with a kinematic effect. While Act 2 explores beyond the exterior of these floating ruins, the interior, which has similarities with Hidden Palace Zone, being these areas of more precise platforming, the end of the stage, just as in the classic version it ends with one of the collapsing towers.
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 .
