Chemical Plant Zone is the second Zone of Sonic the Hedgehog 2. Like with Green Hill Zone, Chemical Plant would gain infamy of being the flagship level of Sonic 2 and see reappearances in games like Sonic Generations, Sonic Mania and Sonic Forces.
Overview
Set in Dr. Robotnik's chemical plant, this Zone is a token industrial cityscape with a network of pipes that pump blue chemicals that serve as the Zone's many twisting pathways, and numerous loops for extra speed, along with the first-ever appearance of the infamous Speed Boosters, which would see much more frequent use in modern titles. The Zone also features high-speed transport tubes that will take the player from one part of the Zone to another location, harmful blue chemical globs that jump up and down between two points, and floating platforms to ride on.
In the second Act, the Doctor uses a poisonous new substance called "Mega Mack" to try to kill Sonic by poisoning him in mere minutes[4], though mechanically, it's just pink water. While the liquid doesn't pose as much threat at first, the player can potentially enter what is considered to be the most notorious part of the entire Zone: the player must climb a shaft full of moving yellow blocks, and the water level will rise, therefore the player must avoid both drowning and getting crushed by the blocks. It is possible for the player to avoid this section entirely if they take the right path through the Act. The boss at the end is Water Eggman.
The Zone shares palettes and tiles with Robotnik's Death Egg Zone.
Quotes
“ | 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 the Hedgehog 2 US manual[4] |
“ | 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). | „ |
Enemies
Grabber — Spider Badnik, hangs from the ceiling and grabs Sonic. Then unless the player mashes and , or Tails can destroy the Grabber, it explodes and hurts/kills Sonic. | |
Spiny — Anemone Badnik, moves very slowly and spits out projectiles. |
