Angrybirds365.com writes, "The story is simple and inspired by the great novels of Tolkien. The goal is to destroy every orc in each level of Isengard & Mordor kingdoms. An Ed (it’s your slingshot, don’t get confused) will shoot your “birds” against the Orcs. If your attack is well planned and you destroy the orcs with the minimum required “birds” you’ll get a 3 star score. 3starscoring (sic) on all levels of Isengard and Mordor will unlock a new kingdom (Moria) that will be available to conquer."
