Second level, Sonic the Hedgehog 2 |
Number of Acts: 2 |
Boss: Water Eggman |
Underwater areas: Act 2 |
The second zone in Sonic 2, Chemical Plant Zone is Dr. Robotnik's chemical plant, full of tubes and floating platforms. He uses a new substance called "Mega-mack" to try to kill Sonic. The Chemical Plant also makes an apperance in the Adventures of Sonic the Hedgehog episode Mobuis 5000 although its a little bit different from its game counterpart.

Instruction Manual Description
Flash through a high-tech maze built with pipes and ducts. Robotnik's flooded the factory with a pool of toxic liquid called "Mega Mack" that poisons Sonic in a few moments!
Sonic Team Commentary (from Sonic Jam Strategy Guide)
At first this stage was set to appear about after Zone 10. Although there would be fewer Acts this time, we thought having about 18 zones would be good, but having each zone stand out and fit in the story in a way that was easy to follow, in the end it dropped down to 11 zones, and Chemical Plant was placed as the second stage. In the end it was a success (laughs). (Naka)
Enemies
- Grabber - Spider enemy, hangs from the ceiling and grabs Sonic. Then unless Tails can destroy the Grabber, it explodes and hurts/kills Sonic.
- Lander - Anemone enemy, moves very slowly and spits out missiles.
Differences between beta and final
- The loop-de-loop platforms have octagonal edges instead of being flat.
- The platforms which move across rails (most noticeably in Act 2) are much smaller.
