The other half of the best game on Sega Genesis. This time instead of Tails, you can play as Knuckles, who has some stages that defer from Sonic's. Gameplay wise, its the same as Sonic 3's. I mean being the other half and all that's expected. The only difference is this game is noticably harder than any other game the first time you play it. It also lacks a water level (which is good to alot). But the emerald stages are a pain to go through. Despite being Blue Spheres again, these stages are also noticably harder. So if you're playing this game on its own, expect to not finish the game with all emeralds and be unable to use Super Sonic or Super Knuckles. This one also has no save so hope your Sonic skills are up for it.

I don't have much else to say aside from these. So if you want a more extensive review, then just read my Sonic 3 review.
