Sonic X Shadow Generations for Nintendo Switch combines two games in one release. The new Shadow campaign follows Shadow as his enemy Black Doom returns, with Doom Powers, the return of Chaos Control to stop time, secrets to find in a hub world called White Space, and stages drawn from his past adventures. The package also includes a remaster of Sonic Generations, where Classic Sonic and Modern Sonic race through 2D and 3D zones from the series history with improved visuals and bonus content. It is a single-player SEGA game for TV, tabletop and handheld play, rated E10+ by the ESRB. This is a new, sealed Nintendo Switch game card.
