Link returns as his adult self to bring out the hero (and animal) in himself.
Combat is pretty much the same as the rest of the Zelda games. This counts for human link only. You lock on, take out your sword, attack, and with a satisfying little explosion, their gone. I repeat, for human link only. As a wolf, swinging the wii remote will get you to lunge and bite, sort of like a sword attack as regular link. When you jump attack, it's pretty much the same thing, until you cling on to the enemy and start rapidly biting the enemy (think grab attack in smash bros melee). When Midna is on your back, you can hold B and charge up for pretty much a one-hitter for every enemy in the big, red, field around you. Like a lot of people, one of the highlights of these Zelda games is horseback riding. Particularily fun is to run around hyrule field and run over as many enemies as possible. My sister and me have a lot of fun doing this with me holding the nunchuck and my sister holding the remote. One of the greatest parts of horseback riding for me is horseback combat. There is nothing more satisfying than running up beside an enemy on horseback, and beating the tar out of him with your sword. They even made a little jousting minigame out of it. As the sequel to OOT not much went wrong with this game, and boy, that dark story was definately my Zelda style. For those who thought wind waker was bad because of it's art style (you're wrong anyway) this is a must have for adult link fans and adventure fans.
