The Sega Game Gear version of X-Men likely provided an action-packed experience based on the popular Marvel comics. Without detailed developer information readily available, it's safe to assume the game featured gameplay involving side-scrolling levels or perhaps fighting game-style action.  The Game Gear's technical limitations would have guided the graphic style and gameplay mechanics, possibly simplifying the complexities of larger console versions.  Sega's publishing role is central to the game's release and distribution.
