Harry Potter and the Chamber of Secrets is a 2002 action-adventure game published by Electronic Arts. The game's core gameplay is simple. Taking control of Harry Potter, the player explores Hogwarts castle and grounds. Throughout the course of the game, the player will encounter events that tie into the storyline of the second Harry Potter book. Filling the gaps between these events are various classes, where the player will learn how to fly a broomstick and learn new spells for combating bosses, among other things. Each new spell is accompanied by a challenge, which the player must get through in a certain amount of time to complete that class period.
