The video game is a sequel to the 2001 Disney Interactive and Square collaboration, Kingdom Hearts, which combined Disney and Square elements into an action role-playing game.

Like the previous installments, this game features a large cast of characters from Disney films and Final Fantasy games. Organization XIII, a group introduced in Chain of Memories, also reappears to impede Sora's progress.
