MabsKMK's Chemical Plant Zone uses sprites taken from Sonic the Hedgehog 2, though the ChemicalPlant2 and ChemicalPlant4 definition files recolour the background buildings to match their appearance in the Sonic - The Lost Land 2 ROM hack, while also adding a fog effect that partially obscures the lower parts of certain background objects.
