Amazon has announced that it will release 'Kingdom Hearts 3', a crossover action role-playing game developed and published by Square Enix, for $40.99, instead of $59.99, for one day to players placing a pre-order for a copy.

Christian Today reports that despite the announcement of the 2015 launch window and the 20 percent discount, fans are still wondering what the game, which they have been waiting for about a decade now, has in store for them.

However, fans are aware that the upcoming game will incorporate various Disney characters in adventures as well as magic, as they pass through rich and massive worlds. It is also being said that in 'Kingdom Hearts 3,' players will see big and popular universes coming head-on. In fact, Square Enix has been working fervently on this game with a view to make it worthwhile for its fans and, hence, it is expected that the developer may well incorporate a number of popular 'Star Wars' character like Darth Vader, ice queen Elsa from the animated movie "Frozen" or even Marvel superhero Iron Man into the game.

However, as of now, these reports have not been confirmed by Square Enix.

In reply to a question on which iconic worlds would be chipped in the game, Tai Yasue, 'Kingdom Hearts' co-director and game designer, told Game Informer in July 2014, "It's going to be a mix. Whenever we come up with worlds for 'Kingdom Hearts,' we want to have them be varied. You don't want the same type of world, so we will have different categories. That will make it feel fresh, like you're having an adventure."

At the same time, Yasue told Kotaku U.K., "For 3, we want to evolve it in a new direction, but at the same time we don't want to change what is fundamental about Kingdom Hearts. We're hiring new people continuously, so they are learning about Kingdom Hearts through making 2.5. It's a good learning experience."
