Chemical Plant Zone is the second zone in Sonic Mania, which is based on Chemical Plant Zone from Sonic the Hedgehog 2. The player is sent here by the power of the Phantom Ruby at the hands of Dr. Eggman.
Act 1 is very similar to the original and incorporates level design from both acts of the original, with winding passageways, pipes, harmful chemical balls, and, of course, Mega Mack. New additions include an entirely new bottom route and Metallic Madness-style pipes where you choose your own path.
Act 2 has Sonic and the gang exploring deeper into the plant to an indoor section, with large beakers and jars present in the background. The blue chemical that composes the ball snakes from Act 1 now appear in large pools. By standing on giant syringes, this hazardous fluid can be transformed into a gelatinous substance that can be bounced on, propelling you high into the air. Along the way you'll find large DNA strands that carry Sonic through the air, encased in a bubble of Mega Mack. Sticky platforms that slide across walls and ceilings can be clinged to and jumped off of to move to different areas of the Act.
After defeating the boss of the zone, the player takes a transport tube that leads to Studiopolis Zone.
