Baldur's Gate: Dark Alliance is set in the fantasy world of Faerûn, where a group of mercenaries must navigate through treacherous landscapes and battle fearsome enemies. The game follows the story of a human mercenary who is hired for a series of high-paying jobs, but soon finds himself entangled in a larger conspiracy.
The gameplay in Baldur's Gate: Dark Alliance on GameBoy Advance is similar to the console version, with action RPG elements and a focus on combat. However, the handheld format means that the game uses an isometric perspective with two-dimensional graphics, and the player character can only walk and use abilities.
The gameplay is still fast-paced and intense, with a variety of enemies to battle and treasures to find. The player must choose their classes carefully, as each one brings its own unique abilities and strengths.
