X-Men 2: Clone Wars is the title of a video game released in 1995 by Sega of America for the Mega Drive/Genesis. The game is a sequel to its 1993 side-scrolling video game titled X-Men. Oddly enough, the European release of the game reused the same cover art of X-Men 2: Game Master's Legacy for the Game Gear, a different and unrelated game. The game was given a KA (Kids to Adults) rating by the Entertainment Software Ratings Board. It is based on the successful TV series from Marvel Comics.
