The video game Harry Potter and the Chamber of Secrets was released in 2002. It was published by Electronic Arts and developed by Eurocom for the PlayStation 2, Xbox, and GameCube systems. It was simultaneously ported to the PC/MAC and the Game Boy Advance and Game Boy Colour handheld systems.



Note: not all characters appear in all versions of the game.

  • Harry Potter: Main character and only playable character.
  • Ron Weasley: Harry's best friend, usually seen leading Harry to class or to the Quidditch stadium, or in cut scenes. In the PC/MAC game, Ron usually leads Harry to challenges instead of classes.
  • Hermione Granger: Harry, other best friend, a brainy girl who is rarely with Harry most of the game, except in cut scenes. She is petrified toward the end of the game. In the PC/MAC game, she also leads Harry to classes.
  • Ginny Weasley: Ron's little sister, who Harry has to rescue at the end of the game. In the PS2, GameCube and XBox versions, Harry also has to find several things that she lost in Diagon Alley.
  • Fred and George Weasley: twins, older brothers of Ron and Ginny. They have a very minor role in the PC/MAC version (they set up the bean trading system seen throughout the school and grounds), but in the PS2/GameCube/XBox versions, they give Harry a refresher on the Flipendo spell, teach him how to toss gnomes, and once back at Hogwarts, they open a shop in Gryffindor Tower where Harry can purchase items like Stink Pellets and Dungbombs, Famous Witches and Wizards cards, and the Alohomora spellbook. In the Gamecube and XBox versions, The shop is only open at night and on the last day before you enter the Great Hall. In the PS2 game the shop is open at any time.
  • Neville Longbottom: one of Harry's roommates; a clumsy, forgetful boy. In the PS2/GameCube/XBox versions he gets trapped behind a tapestry, and Harry has to find the Diffindo spell in order to free him. He is not present in the PC/MAC game.
  • Draco Malfoy: Harry's arch-enemy, usually found sneaking around at night. Harry also duels him at the Duelling Club. In the PC/MAC game, Malfoy is also seen at the House Point Ceremonies.
  • Moaning Myrtle: a ghost who haunts the second-floor girls' bathroom.
  • Albus Dumbledore: the Headmaster of Hogwarts. While normally absent from a good part of the game, he features prominently in a cutscene in which he tells Harry that he does not think that Harry is the Heir of Slytherin. He also appears at the end of each day to announce the latest house point totals.
  • Professor Snape: the Potions teacher. Known for being unusually strict, he is usually to be found in the dungeons, near his classroom. In the PC/MAC game, if you get caught in the Slytherin common room while running away, Snape shows up and punishes Harry.
  • Professor McGonagall: the Transfiguration teacher. Her classroom is located on the left side of the second floor in the PC/MAC version. Also in the PC/MAC version, she isn't seen very often because Harry doesn't have any Transfiguration classes. There is a time in between classes/challenges when the classroom has just been open when McGonagall is holding a class. If Harry enters the classroom, she will give him a warning and send him out. If Harry enters a second time, McGonagall will take 5 house points away. She also leads Harry to Dumbledore's study when Nearly Headless Nick has been petrified.
  • Professor Flitwick: the Charms teacher. His classroom is located on the right side of the second floor in the PC/MAC version.
  • Professor Lockhart: the Defence Against the Dark Arts teacher. His classroom is located on the third floor. He also is in charge of the duelling club, and accompanies Harry and Ron into the chamber.
  • Rubeus Hagrid: a very large half-man, half-giant, usually found in his cottage on the grounds. He is also seen in a cutscene where he is taken away to Azkaban. In the Xbox and PS2 games he is in the Leaky Cauldron
  • Professor Sprout: the Herbology teacher. She teaches in the greenhouses, which are located on the right-hand side of the grounds.
  • Madam Hooch (PS2, GameCube and XBox): the Flying teacher. She teaches a flying lesson in an outside lawn area, and thereafter is always found there during the day if Harry wants to try to improve his score on the flight training course.
  • Oliver Wood (PS2, GameCube and XBox, and PC/MAC): Gryffindor Quidditch Captain. He calls Harry to his first Quidditch practice of the year, and thereafter is always found at the Quidditch stadium during the day if Harry wants to try to improve his practice time for catching the Golden Snitch. In the PC/MAC version, Wood appears after Harry's first Defence Against the Dark Arts Class. Wood leads Harry to the Quidditch pitch, and re-teaches Harry how to play Quidditch.
  • Percy Weasley (PS2 and XBox, and PC/MAC): a Gryffindor prefect, older brother of Fred, George, Ron, and Ginny. Percy can be found in the Gryffindor Tower study room at night; he does not like to be disturbed, and will throw Harry out of the room if he sees or hears him. Unfortunately, the only way to reach Fred and George's shop (see above) is through the study room. In the PC/MAC game, Percy is only seen in Gryffindor tower if Harry visits there in between classes/challenges.
  • Peeves, a goofy looking poltergeist. Harry meets him repeatedly in the game. This is also the first and only game in which he is shown to have a "napping place" and the ability to shrink.
