Over a year after the successful release of Kingdom Hearts II (2005), Kingdom Hearts II Final Mix (2007) did many improvements that Kingdom Hearts Final Mix (2002) did to the original game.
While the first Final Mix added a few extras, II Final Mix added a subplot told by cutscenes with voices. It also gave players the ability to battle all of Organization XIII, rather than some of them as in the original game.
As in the original Final Mix, the game had additional enemies, an extended post-credits scene and a bonus mini-game.
The most notorious boss in Kingdom Hearts history is Lingering Will thanks to his high difficulty and very high amount of health. His appearance was made to tease Kingdom Hearts Birth by Sleep (2010).
Kingdom Hearts II Final Mix is the only version of Kingdom Hearts II to appear on both the PlayStation 3 and the PlayStation 4.
II Final Mix is an even better version of a great game.
