Ubisoft today announced that Prince of Persia: The Fallen King will be a Nintendo DS exclusive. Developed by Ubisoft’s Casablanca studio and expanding the saga with an independent storyline, The Fallen King utilizes the stylus controls of the DS system to deliver both acrobatic and combat action. The game follows the prince as he escapes to a deserted kingdom that seemingly offers sanctuary from imminent danger. Unfortunately, a dark substance has physically contaminated the land and the skies above it. As the Prince seeks a way to fight the spreading corruption and stop it from destroying the land, he encounters a partially infected creature that promises salvation. Is the creature truly an ally or merely an enemy in disguise? You can find out this holiday season, when Ubisoft releases the game to retailers nationwide.
