Sonic the Hedgehog: Night of Shadows is a Sonic fanon game for Nintendo Wii, Playstation 3, and Xbox 360. ... ..... ....... I don't feel like saying any more. It'll ruin the surprise. Let's just say some new faces turn out to be switched old ones. The game plays through in chapters, and at anytime a player may return to a previous chapter to replay it, be it for fun or to recall the story.
