MacWorld - Run, jump, climb, shoot, and duck for cover. With Shadow Guardian by Gameloft, the iOS finally gets a vibrant, full, swashbuckling-fun action-adventure game. You play as Jason Call, and the fate of the world rests upon your shoulders. Mercenaries battle you for control of an ancient relic, the Prima Materia in this third person action title. Drawing inspiration from the Uncharted and Tomb Raider series, Shadow Guardian is a moderately successful attempt to bring treasure hunting action to the iOS platform.
