Chemical Plant (ケミカルプラント Kemikarupuranto?) is the second Stage in the console/PC version of Sonic Generations. It represents Sonic the Hedgehog 2 in the Genesis Era. It is based off of the original zone from Sonic the Hedgehog 2.


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 machine claws controlling the place leading to the original Mega Mack rising. When escaping, the player will run through a loop, thereby causing him to hit the Goal Plate.

Act 2

Modern Sonic starts (as usual) running through combo tricks and special ramps directing him to the 2 roads. Both the high and low lead Sonic to a large tube, sending him down with the blue chemicals. After he falls, Sonic runs into a room where the Mega Mack is beginning to rise (just like in Act 1), but deeper and slightly quicker. This time when escaping the area, the Chemical Plant is self-destructing. He then proceeds to the Goal Ring to escape the destruction behind him. The Modern remix has a very sci-fi feel, reminiscent of shows such as the X-Files.


Challenge Acts

Act 1

Act 2


  • Act Two looks similar to the Daytime stages of Eggmanland from Sonic Unleashed.
  • In Act One of the Classic version, the level's theme sounds very similar to the original Chemical Plant Zone music, except the drum sounds are played as a techno beat and it is not a 16-bit theme. The Modern version of the theme is a lower-pitched rock remix.
  • As seen in the video, the Mega Mack in Act Two is deeper than in Act One, but like in the original Chemical Plant Zone, the Mega Mack in Act One is constantly rising.
  • In Act Two of this stage, the Chemical Plant seems to be self-destructing.
  • Even though the pink Mega Mack is considered deadly like most of the liquids, Amy finds it pretty.
  • This is the only stage in the Classic era that doesn't have a "Fast" remix.
  • This is the first level to feature the Light Speed Dash.
  • In Act Two, Super Sonic cannot push the yellow blocks with Boost. As a result, it is possible for him to get stuck in submerged places until he runs out of rings.
  • The Modern stage contains a water slide that is reminiscent of Lost World from Sonic Adventure and Cannon's Core from Sonic Adventure 2. This is most likely a coincidence, however.
    • Like Chemical Plant Zone, Cannon's Core also contains differently-colored water.
  • This zone contains fewer Badniks than any other zone in Generations.
  • The background music for Act Two can be considered by some as the most different of all of the Modern remixes to the originals.
