The Avatar: The Last Airbender video game allows the player to control one of four characters – Aang, Katara, Haru, or Sokka – in a single-player adventure. Each character uses his or her own trademark weapon and fighting style, and is able to earn new special abilities through experience gained from defeating enemies. A variety of items can help the player with quests, or during battle (armor, chi, enchanted accessories, and healing potions). The game also enables the player to collect certain resources and bring them to artisans to make special items. Enemies include classic Firebenders, machines, and a variety of animals from the show, mainly the first book.
The Wii version varies with regard to the hot/cold minigame where the player's controller vibrates to help the player find hidden items. When the player finds the item, in most console versions, the player repeats a rhythm minigame until having a successful round. In the Wii version, there is a calligraphy minigame with the Wiimote instead. In combat, the Wii version requires that the player swings the Wiimote while pressing the button for a special move (in Aang's case, swinging his staff down to unleash a gust of air to knock enemies down), whereas the other versions only require pressing the button.
