With the exception of a forest and a cave, the game takes place entirely on Hogwarts and its terrains. Although other places are mentioned and illustrated in drawings during the intro and outro of the game, they do not appear not even in cutscenes. Since the game is not open-world, each location can only be played in the levels they are not blocked. In this game, there are a few things to keep in mind: the first floor is mistakenly referred to as "second floor"; classroom 2E is located in the fifth floor instead of the third; the Underground Chambers are located in the third floor instead of the Dungeons.

Areas appearing only during cutscenes

Debug mode

The game has a debug mode, which can can be accessed by typing set engine.playerpawn harrydebugmodeon when in game. It shows the Unreal Engine at the top part of the screen, which has notably green characters. It might not work the first time, but if the player keeps trying or uses the wand it will certainly activate. The key F7 can be pressed to turn it off.

Once in the debug mode, the player can access the level list in the main menu and play any level any time (although the save books may not have effect with the debug mode activated).

By pressing a certain key on the top left region of the keyboard (normally ' or ~, although it varies depending on the keyboard), the player will open the game command engine. Then the player must type bcheatsenabled true and press enter. Once this is done, the following cheats can be inserted (not all of them will work all the time and they may not work at all sometimes):

  • ghost - opens ghost mode
  • fly - opens flying mode
  • walk - deactivates ghost and flying modes
  • givebeans - adds an amount of beans
  • givehousepoints - adds an amount of Gryffindor house points
  • giveseeds - adds an amount of seeds
  • giveallcards - adds all Wizard cards
  • harrysuperjump - makes Harry jump very high (may also work outside the engine)
  • harrykoresh - makes Harry invincible
  • killharry - makes Harry faint
  • killall - stuns all other present creatures
  • setspeed - accelarates the game speed
  • quit - quits the game


Differences between the book/movie and this game version

  • Peeves does not appear in the film, but is battled twice in this game.
  • The Forbidden Forest detention part is not included in this version.
  • In the book and movie, Neville breaks his wrist after falling off a broomstick from a great height during the flying lesson, what allows Malfoy to steal his remembrall. In this version, Neville is not seen flying or wrist-broked at all, nor he appears at Harry's Flying lesson. Instead, he gets upset after that lesson, when he arrives and tells Harry that Malfoy has stolen his remembrall.
    • In addition, Neville's anxiety was because he lost Trevor again, and upon his remembrall being retrieved, it is implied that Trevor had been left at the Herbology greenhouse causing Neville to panic. This was neither in the books nor the film.
  • In the book and this version of the game, Malfoy says he might leave Neville's remembrall on a tree for him to find. In the film, he suggests to leave it on the roof.
  • In the film and book, Harry's broomstick is jinxed in the first Quidditch match. In this version, two Quidditch matches happen but neither have jinxed brooms or accidents.
  • In the book, Quirrell summons ropes to tie Harry by snapping his fingers. In the film, Quirrell snaps his fingers to make fire surround the area. In this game, Quirrell also conjures fire, but does so by moving his hands.
  • Harry fights Draco with Christmas crackers. In the books and movies, Harry doesn't fight Draco at all until Year 2, despite challenging Harry to a duel (that didn't happen) in the first book.
  • Harry gets trapped in the dungeons before Potions class, what doesn't happen in the book or the film.

Behind the scenes

  • The Dursleys have model files in the game, what suggests they were going to appear.
  • Many more spells were planned to appear in this version of the game. Those included Reparo, Verdimillious, Avifors, and even spells that don't make an appearance anywhere else in the franchise, including Flintifors, Ectomatic, and an unnamed transfiguration spell. Also, Incendio and Wingardium Leviosa were to have more uses.
  • In the opening level, Dumbledore tells Harry Potter he had found a room filled with chocolate frogs, and later returned to the same room only to find fire crabs instead. Some say this may be an allusion to the Room of Requirement, first mentioned in Harry Potter and the Goblet of Fire, released in the year before this game. However, the room always contains what one is looking for, and Dumbledore suggests that these encounters were unexpected. It also seems unlikely that Dumbledore would have been looking for fire crabs.
