In this 3D adventure, players must navigate through the castle and beyond to solve puzzles and avoid traps. Each character has unique skills: Harry can leap across chasms and climb ropes, Ron can sense secret areas, and Hermione can fit into small spaces. Players can also control other characters like Hedwig the owl or Buckbeak the hippogriff to overcome obstacles.
The game is set during the year when Harry became known as "The Boy Who Lived", and players must survive this year while learning new spells and uncovering the truth about Sirius Black's role in his escape.
