The Legend of Zelda: Skyward Sword is an action-adventure video game in which players take on the role of series protagonist Link through a series of monster-populated overworlds and navigating dungeons featuring puzzles and bosses. Link is controlled using the Wii Remote and Nunchuk, and the Wii MotionPlus expansion device is required to play. The greater majority of gameplay mechanics revolve around use of motion controls: these include camera control with the Nunchuck and general hotkey actions and movement linked to the Wii Remote. Jumping across gaps and scaling ledges happen automatically within context. The Nunchuck is also used to make Link perform a forward roll. Link can sprint for short distances, but sprinting and other actions such as climbing and carrying heavy objects is limited by a stamina meter, which recharges after a few seconds when not performing actions that drain it. When depleted entirely, Link's movement speed is reduced and he is left vulnerable until the meter refills. Standard navigation takes place from a third-person perspective, while the Dowsing search function switches to a first-person view: Dowsing scans an area for a selected object, with new Dowsing objectives appearing depending on game context.
