Released in 1995, X-Men 2: Clone Wars is a platform game created by Headgames and published by Sega of America for the Mega Drive/Genesis. Serving as a sequel to 1993's X-Men, the game is inspired by the Marvel Comics superhero team, the X-Men.

This marks Sega's second X-Men game for the Genesis. In this instalment, an extraterrestrial entity called the Phalanx aims to take control of the Earth, and the X-Men emerge as humanity's last line of defence against this impending threat.

The gameplay closely resembles the side-scrolling action of its predecessor. Notably, there is an expanded roster of playable characters, including Beast, Gambit, Nightcrawler, Psylocke, Wolverine, Cyclops, and Magneto.
