Metal Sonic Hyperdrive (Hack Playthrough)

I play as the skull guy, because who wouldn't play as a skull guy when given the chance? This hack of Sonic has 5 whole characters to play as, and some great levels to play them in. Each boss has a twist to them as well. I especially liked what was done to the Labyrinth boss, because that guy was just the worst. This hack is made by Darkon360 and others!
