Much of Act 2 of Death Egg Zone involves walking on the ceiling. There are three ways to reverse gravity: hitting a Switch on the ground, running through an antigravity tunnel, or taking a ride in a High-speed elevator.
In Cosmic Angel Zone, gravity sometimes switches at will. Using the guided cannon systems can also switch gravity.
In Death Egg MK.II Zone, Sonic switches from floor to ceiling very rapidly and randomly. While gravity is reversed, the crouch and look up commands are also reversed, meaning the player has to press down to look upwards and up to crouch. The final boss takes place in an antigravity chamber with three concentric electrified rings.
