This also allows for the sword to be integrated into puzzles to a greater extent than in previous titles. In contrast to earlier installments, battles do not focus solely on timing attacks, but also on their target, such as the direction in which enemies are hit. Skyward Sword heavily integrates the use of the Wii MotionPlus swordplay, for instance, is integrated with the controller to a point where the player has one-to-one motion control over Link's sword and its attack directions. Skyward Sword requires either the Wii MotionPlus add on or a Wii Remote Plus. Nearly 5 years in development, the Skyward Sword departs from many of the traditional Zelda norms, featuring new controls, a new art style, and formula differences. The Legend of Zelda: Skyward Sword (ゼルダの伝説 スカイウォードソード, Zeruda no Densetsu: Sukaiwōdo Sōdo) is an action-adventure game for the Wii console and the sixteenth entry in the Legend of Zelda series.
