Résumé

Harry Potter and the Prisoner of Azkaban is the sequel to Harry Potter and the Chamber of Secrets for PC and Mac, and features similar action-adventure and platforming gameplay. The player controls both Harry as well as his friends Ron and Hermione, while casting spells, solving puzzles and fighting enemies. When not engaged in a specific mission, the castle of Hogwarts can be freely explored. Scattered all around Hogwarts, usually in hidden areas, are Every Flavour Beans, Pumpkin Pasties and Cauldron Cakes, which function as a sort of currency. They can be traded for Collectors Cards, passwords for portraits that lead to more secret areas, and power-ups.
