Along with the recent trailer debuting the game's opening (see below), Nintendo has released a huge batch of info on the new additions to the Zelda universe with Skyward Sword.
Faron Woods and Skyview Temple: The forest is the first location Link visits after leaving Skyloft, an island world suspended high in the sky. The people of Skyloft have never been to the surface, so this marks a strange new experience for Link. Traversing the forest leads him to Skyview Temple, where Zelda may be being held.
Dash: By holding down the A Button, players can make Link run faster and grant him acrobatic abilities, such as the ability to briefly run up a sheer wall to grab onto a cliff. This uses up some of Link's stamina, which replenishes itself over time after they stop using Dash. Certain powerful attacks, such as the Spin Attack, also use up stamina. When all of Link's stamina is used up, his movements become slower for a few moments while he recoups his energy.
Master Sword, Master Item Detector
Dowsing: Fi, the spirit of the powerful Goddess Sword and Link's guide, informs Link that he can use the sword to search for things through dowsing. In dowsing mode, when Link holds out his sword, the sword will beep when pointed in the direction of the intended target which will flash. This technique can be used to search for many objects and characters in the game. In Faron Woods, Link uses it to search for Zelda, guiding him to Skyview Temple, where Zelda's aura can be detected.
Kikwi: The Kikwi are cute, fuzzy creatures that Link encounters while exploring the forest, resembling a cross between a plant and an animal. Link can search for the Kikwi in the forest using dowsing to aid him in his search for Zelda.
Old Weapon, new tricks
Slingshot: This is one of the first items that Link receives in the game. While it's not very powerful, it can be used to stun enemies and activate objects in the environment. As with many items in the game, players aim the slingshot by moving the Wii Remote™ Plus.
