Hydrocity is a cross between Chemical Plant Zone from Sonic 2 and Labyrinth Zone from the original Sonic. Lots of water but with loads of steep slopes allowing you to gain some incredible speeds. Plenty of moving platforms and loads of fans around to make you hover in the air. The rev-up treadmills are an excellent touch. Sonic stands on a small rotating platform and then is let off at speed. When you rocket down the side of a wall and glide across the top of the water is what Sonic is all about.

Robotnik is fought in a shallow depth of water. He creates a vortex which can suck Sonic up to his propellers. He then drops that will explode after a few seconds. A correctly timed jump onto their fountain will push you upwards in order to get a hit.

The aqua shield will allow for jumps high enough to land a hit.
