Legendary PS3 Game

All the creatures of myth, legend and lore are real-they've just been sealed away for thousands of years inside Pandora's Box. When a thief named Deckard is hired to steal an ancient artifact, he unwittingly triggers a war between man and myth. Giant Gryphons rule the skies, Werewolves tear the innocent limb from limb and cities are held under siege as creatures we'd dismissed as the imaginings of our ancestors prove to be very real and very angry at being prisoners for untold milennia. As the only person able to seal the box, Deckard finds that he must work with a shadowy secret society to save civilization before it's torn apart by tooth and claw.
