Another classic zone has been revealed for Sonic Mania, and this time its Chemical Plant Zone! Two videos have been showcased for it, which you can check out in the links to the announcement on Game Informer below (who refer to the stage as Chemical Factory – although this is likely an error).
The first video shows off Tails in a section that looks rather different to the familiar set pieces of Chemical Plant, so this may be an act 2. It even shows off a new gimmick; jelly-like water and obstacles that you can bounce off or stick to with different colours to go with them. The second video shows off Sonic in a far more traditional-looking section, facing the ever-dreaded block climbing from the original game.
We will update when there are some videos that can be embedded for easier viewing, but for now this joins the three already confirmed classic zones coming back.
