Nintendo's best-selling Legend of Zelda franchise returns to Wii with enhanced sword fighting controls and a new setting that takes place high above the clouds. Set before the events chronicled in 1998's Ocarina of Time, the elfin hero known as Link will alternate between two disparate worlds, a chain of floating islands in the air and a network of dungeons far below by using the ancient powers of the titular blade. While previous games featured riding and sailing, Skyward Sword has Link flying. Link will be able to use a large bird to glide, dive, and climb to explore his surroundings. On land, Link must defend himself against an assortment of creatures with his sword, which now takes advantage of the enhanced motion detection found in the Wii Remote Plus. Each thrust, slice, and parry by the player will be carried out by Link at the same time. Other motion-sensitive controls allow players to roll bombs, shoot arrows, and steer flying objects toward their targets. Initial runs of Skyward Sword include as a special bonus, a compact disc with selected music from "The Legend of Zelda 25th Anniversary Symphony." Once supplies have run out, the disc will no longer be included with the game. A limited edition bundle is also available for purchase, which includes the music CD, the game, and a gold-coloured Wii Remote Plus controller emblasoned with the Hylian Crest.
