Players take control of Harry Potter and the Order of the Phoenix , navigating through the castle of Hogwarts and beyond as he faces the dangers of his fifth year. The story follows Harry's efforts to build Dumbledore's Army and face off with Voldemort, all while dealing with an unfolding prophecy.
The gameplay consists of various minigames, including timing-based button presses on the GBA or stylus movements on the DS touch-screen. Players will need to use their magical skills to overcome obstacles and solve puzzles in both 3D pre-rendered backgrounds and traditional side-on views.
