Nintendo vs Sega

Nintendo vs Sega is a Marvel vs Capcom-style fighting game using the CPS-II engine. It has the same style as the original MvC game, only with Nintendo and Sega characters.

Following his defeat, Master Hand gains strange new abilities, including dimensional distortion. Months later, he uses these powers to find Mario and exact his revenge.
