To defeat enemies and progress through the game, Shadow can use a variety of weapons from each faction and complete missions that will determine the game's plot and subsequently playable levels. Shadow the Hedgehog reintroduces third-person shooter elements from Sonic Adventure and Sonic Adventure 2, but greatly expands upon the concept and introduces nonlinear gameplay to the Sonic franchise.
The game follows Shadow the Hedgehog, a creation of Doctor Eggman's grandfather, as he attempts to learn about his past while suffering from amnesia. Shadow the Hedgehog is a 2005 platform game developed by Sega Studios USA (the former United States division of Sonic Team) and published by Sega as part of the Sonic the Hedgehog series.
