Although Sonic Mania includes the Sonic 3 special stages, a brand-new special stage was designed for collecting Chaos Emeralds, and it’s a delight. Drawing inspiration from Sonic CD, this one requires you to chase a UFO around a racetrack, collecting items to boost your speed and rings to extend the time limit. It’s one of the series’ best, and the Saturn-style polygonal graphics are the icing on the cake.
