For the longest time, the Kingdom Hearts series has had zero presence on Xbox platforms. That changed this year with the release of Kingdom Hearts 3, and next year, Square Enix will be going back further to bring all of the series’ various remastered collections to the Xbox One. This means that within a year’s time, Xbox loyalists will be able to purchase both Kingdom Hearts 1.5 + 2.5 ReMix and Kingdom Hearts 2.8: Final Chapter Prologue without having to buy a PS4 first.
This is something that Xbox fans have been waiting for a long time. As much as they've been eager for the franchise to make its way onto their platform of choice, they weren’t altogether satisfied with just getting the finale to the storyline the series had been building up for the last 17 years. Understandably, there's been hope that the rest of the story would someday be added, even though Square Enix wasn’t sure if it would ever bring classic Kingdom Hearts games to Xbox as recently as last year.
Kingdom Hearts 1.5 + 2.5 ReMix includes the Final Mix versions of Kingdom Hearts and Kingdom Hearts 2, along with the spinoffs Kingdom Hearts: Re: Chain of Memories and Kingdom Hearts: Birth by Sleep. Additionally, the collection rounds things off with the remastered cutscenes from mobile titles Kingdom Hearts: 358/2 Days and Kingdom Hearts: Re:Coded.
Meanwhile, Kingdom Hearts 2.8: Final Chapter Prologue consists of the remastered 3DS title Kingdom Hearts: Dream Drop Distance, the one-shot story Kingdom Hearts 0.2: A Fragmentary Passage, and the hour-long movie Kingdom Hearts: Back Cover. Between this and 1.5 + 2.5 ReMix, Xbox players will be able to finally experience everything that leads up to Kingdom Hearts 3. Whether that will make it easier to understand Kingdom Hearts’ story at all is another matter entirely.
Speaking of Kingdom Hearts 3, Square also announced at X019 that a demo for that game is now available for Xbox One. This will give Xbox fans interested in the series something to bide their time with while they wait for the rest of it to come out.
