Chemical Plant (Sonic Generations)

Chemical Plant Zone is a stage in the new game Sonic Generations in the Genesis Era of the game, representing Sonic the Hedgehog 2. It is based off of the original zone from Sonic the Hedgehog 2. It is also home to Metal Sonic (Classic), who can be found in the hub. Talk to him to engage in the first Rival Battle.

Act 1
Classic Sonic starts out next to two roads leading a quarter of the level then leading into a new place (a mechanical room)with mechine claws controlling the place leading to the original Mega Mack rising. When escaped the player will lead to loop making you hit the goal plate.

Act 2
Modern Sonic starts(as usual)runing through combo tricks and special ramps making him lead to the 2 roads also skydiving at some other part. Later,(just like act 1), Sonic runs into a room where the Mega Mack is rising, but deeper. This time when escaping, the chemical plant is self-destructing having to run for the goal ring.

 * In the Classic version, the music sounds very similar to the original Chemical Plant Zone music, while the Modern version has a lower pitched rock remix.
 * As seen in the video, the Modern Mega Mack is deeper than the Classic Mega Mack, but like the original Chemical Plant Zone, the Classic Mega Mack is constantly rising.
 * The Chemical Plant seems to be self-destructing in the Modern version of the stage.
 * Even though the pink water is considered deadly by most of the characters, Amy finds it pretty.
 * This is the only stage in the Genesis Era that doesn't have a "Boost" remix.
