The Avatar video game allows the player to control one of four characters - Aang, Katara, Haru, or Sokka - in a single-player adventure, similar to Baldur's Gate: Dark Alliance. 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. There are also a variety of items to help the player with quests, or during battle (armor, chi, enchanted accessories, and healing potions). The game also enables the player to collect certain items and bring them to artisans to make special items. Enemies include classic Firebenders, and a variety of animals from the show, mainly Book One: Water.
