Shadow the Hedgehog (Game) - Giant Bomb

A darker, grittier, and edgier spin-off of the Sonic the Hedgehog series starring the mysterious amnesiac antihero Shadow the Hedgehog. It is one of the series's more controversial games due to it's edgier themes (including use of slight amount of profanity and gunplay).
