There are many little nuances of Sonic 4 Ep. 2 that need exposure, so without further ado here’s the tip guide!
Special Stage tip: Maybe it’s just me, but I didn’t know that if you held down Y you could boost. It doesn’t activate right away which is why some people (like myself) might not know it exists, but it is required to pass Special Stage 7 in the giant loop section.
Red Ring Tip: In Oil Desert Act 2, there is a red ring right below where you start. To get this ring surrounded by slick oil, go down the pipes and fly to a solid platform with a spring on it by using Tails’ flight. Then, aim left and activate the Tails rolling combo, which will effectively run you up the oil pipes and into the red ring.
