Square Enix has compared the new versions of the games included in "Kingdom Hearts HD 2.5 Remix" to the original releases. According to a report from NZ Gamer on Sept. 1, the publisher revealed that "Kingdom Hearts 2 Final Mix is getting a complete overhaul in terms of its original soundtrack. As a result, more than 90 pieces have been rearranged using an orchestra. The remastered port also adds new missions based on the Gummi ship as well as a secret movie that ties the second numbered installment of the series to "Kingdom Hearts: Birth by Sleep Final Mix."
The remastered version of the original PSP game is also getting some extra features. "Kingdom Hearts: Birth by Sleep Final Mix" comes with new abilities based on action and support elements along with some new items. Furthermore, players will also be able to use the “Rhythmic Mixer” command.
The last game in "Kingdom Hearts HD 2.5 Remix" is "Kingdom Hearts Re:coded." Although Square Enix decided to only include cut scenes instead of gameplay, the company is also adding new movies based on several boss fights. One of the examples mentioned has the data versions of Riku and Sora squaring off.
"Kingdom Hearts HD 2.5 Remix" is coming out in Japan two months before the major western regions. The compilation will launched in the Japanese territory on Oct. 2 and then be released on Dec. 2 in North America. Europe is getting the same product three days after the North American launch.

"Kingdom Hearts HD 2.5 Remix" should bridge the gap between the first collection, "Kingdom Hearts HD 1.5 Remix," with the upcoming "Kingdom Hearts 3." The third main installment was officially announced at E3 2013 for the PS4 and Xbox One. However, a release date window has not yet been formally announced for the highly-anticipated sequel.
