Kingdom Hearts series (Unused Beta Elements)

Kingdom Hearts is the role-play video game on the PlayStation 2 which it become so highly positive from the critics, In the process of developing Kingdom Hearts, many ideas are discarded as unworkable for one reason or another.

The Bahamut summon
In the early version from Kingdom Hearts it have to use is Bahamut from Final Fantasy series as an summon but it was been removed, through an cheat codes, a "Bahamut" option can appear in the summons menu and can be selected. But, since there is nothing on the game disc to execute, the game will crash when chosen.

Disney Castle world
As seen in the beta trailer, Disney Castle was originally set to appear as a playable world in the game. But it was completely removed for unknown reasons, but the world can still be accessed with cheat codes, as areas of the world exist from the game's opening cut-scenes. It can still be seen in the world map.

Crumbling Island
An area known as the Crumbling Island was meant to appear in the final level called End of the World as the setting for the final battle with Riku (possessed by Ansem, Seeker of Darkness) at the End of the World. The area was cavernous with purple walls; it had a large amount of running water on the walls, and a large hole in the ceiling. It is reminiscent of Destiny Islands while it was being consumed by darkness. The map for Crumbling Island was placed out of the way within the remains of World Terminus, where it can be found through hacking.

Pride Lands world
Pride Lands from the 1994 film The Lion King was originally going to be a world used in the game, but was removed due to the software having difficulties portraying convincing quadrupedal movement and needing another collision detection engine for the level. Which in the final version of the game that Simba is become as an Summon Gems after his world is been destroyed by the Heartless, It was later featured as a playable world in Kingdom Hearts II.

Alternate logo
At the end of the beta trailer, an alternate Kingdom Hearts logo is shown, the word "Kingdom" in standard golden text on top, the crown just above it, while "Hearts" is displayed in a toned down version of the standard logo's spiked font below. The trademark heart is absent.

Assault Rider
The Assault Rider was going to appear in the game, but was removed because it "didn't fit" in any of the worlds, possibly due to its style. It later appears in The Land of Dragons in Kingdom Hearts II.

Deleted scenes
In the E3 2001 trailer, the scene where the Destiny Islands are destroyed plays out slightly differently from the final game. At the end of the trailer, Sora also manually inserts the Keyblade into the Destiny Islands Keyhole in the Secret Place; in the final version of the game, the Keyblade would shoot a beam to lock or unlock objects.

There are also several cutscenes with Riku that do not appear in the final game, one of which being when Riku is atop the Big Ben, seen staring out, in a crouched position. The other being a moment at the destruction of Destiny Islands where Riku is seen standing in an open arm position staring up and saying something to particularly anger Sora enough to attack him.

Donald and Goofy also have different attires throughout the game, and the cutscene after the defeat of the Guard Armor is set closer to the world door of Traverse Town then in the final game.

And there is a scene where Sora is seen running down an alleyway in Traverse Town from something almost falling over before turning around to look behind him.

Aside from the E3 2001 trailer, and in the final version of the game, a scene where Sora and Riku are exploring the secret place is cut off right as new dialogue appears, but in the continued version of this scene later in the game, no such dialogue appears.
