This was one of the first sega games I got. Game was pretty hard, but very memorable. I played it a lot trying to get to the end. I eventually did after years of trying to figure out what to do in Mojo's stage. It's pretty creative and inventive. The characters were about to be exploded or something and Professor X kept shouting we need to reboot the system and I couldn't figure out what to do. You actually have to press reset on your console for the game to continue. That's some Kojima level shit.
