If Sonic and Knuckles was remixed with new graphics, this is what it might look like. Basically, Robert Medina, also known as BlobVanDam on YouTube, recreated this entire stage using computer graphics. Video after the break.

The only thing bad about this 2.5D rendition of Sonic & Knuckles’ Mushroom Hill? It’s only a video, and not a playable game.
