Hydrocity Zone is the seventh Zone of Sonic Mania, which is based on Hydrocity Zone from Sonic the Hedgehog 3. The player is sent here from Stardust Speedway Zone by Phantom Ruby's power at Eggman's hands after the battle against Metal Sonic.
Unlike most other returning Zones in Sonic Mania, Hydrocity is designed in that all the new level designs and ideas are presented in Act 1, with the main gimmick being the water level being controlled by the player by pulling down certain hooks hanging from the ceiling. By adjusting the water level, the player is able to use other features such as boats to cross the water. In underwater areas, there are buttons that will release giant air bubbles that the player can ride in, much like in Game Gear titles like Sonic Triple Trouble. When riding the bubbles, the player can press or to move, to rise faster, to slow down, and any of the jump buttons to get out. Fans can push the bubble around, which is necessary for getting through certain spots.
Due to the new ideas being employed in Act 1, Act 2 is more straightforward in design, being based on the original Act 2 while having some level design from the original Act 1. All the features the player would come to expect from Act 2 return with the exception of the moving wall, and the addition of underwater currents that pull the player downward in a spiral.
Curiously, the backgrounds are swapped between both Acts, with Act 2's background now used in Act 1 and vice versa. In Act 2's new background, some of the walls have crumbled, revealing large cathedral windows.
In Encore Mode, Hydrocity Zone's palettes have been changed that give the Zone more of a feel akin to Labyrinth Zone. The foreground walls have been given a more goldish hue, and the background colours have been changed the look more yellowish in Act 1, and reddish in Act 2. The water has also become more turquoise in colour.
