![KINGDOM HEARTS Collection [I–III] explained: Every game, platform and story you still need](https://img.g2a.com/700x394/1x1x0/kingdom-hearts-collection-i-iii-explained/149a6985ad5a48e6b66b6f1f)
KINGDOM HEARTS Collection [I–III] launches on October 8, 2026, bringing almost the entire Dark Seeker Saga together for Nintendo Switch 2, PlayStation 5, Xbox Series X|S and Windows PC. But despite the name, this is not literally every piece of Kingdom Hearts story content ever released.
The collection bundles KINGDOM HEARTS -HD 1.5+2.5 ReMIX-, KINGDOM HEARTS HD 2.8 Final Chapter Prologue and KINGDOM HEARTS III + Re Mind. That gets you from Sora’s first adventure all the way through the end of Master Xehanort’s saga, with most of the important games, movies and bridge chapters in between.
The important word there is most. If you want to understand where Kingdom Hearts is heading next, especially before KINGDOM HEARTS IV, there are still several pieces of the timeline outside the collection that are worth knowing.

The short version: Collection [I–III] is the easiest modern way to play almost the complete Dark Seeker Saga. It includes seven playable games or episodes, three cinematic story presentations and Re Mind. To fully prepare for KINGDOM HEARTS IV, you should also catch up on Union χ, Dark Road and Melody of Memory.
Information checked: October 5, 2026. Platform availability, marketplace offers and KINGDOM HEARTS IV release information have been rechecked ahead of launch.

KINGDOM HEARTS Collection [I–III] release date and platforms
The official worldwide launch date for KINGDOM HEARTS Collection [I–III] is October 8, 2026. This is a new native release for current-generation consoles rather than another cloud-only package.
| Platform | Collection [I–III] | Physical | Launch |
|---|---|---|---|
| Nintendo Switch 2 | Yes, native release | Yes | October 8, 2026 |
| PlayStation 5 | Yes | Yes | October 8, 2026 |
| Xbox Series X|S | Yes | Digital | October 8, 2026* |
| Windows / Microsoft Store | Yes, Xbox Play Anywhere | Digital | October 8, 2026* |
| Steam | Equivalent bundle already sold as INTEGRUM MASTERPIECE | Digital | Available since June 13, 2024 |
| Epic Games Store | Main collections available separately | Digital | Already available |
*The Xbox and Windows preorder listing includes 48 hours of early access for eligible purchases made by October 7, which is why some Microsoft Store pages may show an earlier playable date. October 8 remains the official launch date announced for the collection.
The Xbox version also supports Xbox Play Anywhere, so the Microsoft ecosystem is particularly attractive if you want access across both Xbox Series X|S and PC.
What exactly is included in KINGDOM HEARTS Collection [I–III]?
The name can make this sound like a bundle containing Kingdom Hearts I, II and III. It is much bigger than that.
Collection [I–III] is actually a bundle of three existing Kingdom Hearts collections. Together they cover nearly every major chapter of Sora’s story through the end of the Dark Seeker Saga.
In practical terms: you get seven playable games or substantial playable episodes, three cinematic story presentations and the Re Mind expansion for KINGDOM HEARTS III.
KINGDOM HEARTS -HD 1.5+2.5 ReMIX-
This is where a newcomer should spend most of the early marathon. HD 1.5+2.5 ReMIX covers Sora’s beginning, the creation and collapse of several major Organization XIII storylines, and the tragedy that takes place before the original game.

358/2 Days and Re:coded are the first important caveat. Their stories are represented, but their original Nintendo DS gameplay is not. For understanding the main narrative, the movies do the job. Completionists who want the original gameplay experience would still have to look outside the modern collection.
KINGDOM HEARTS HD 2.8 Final Chapter Prologue
2.8 is smaller, but narratively it is where several concepts that matter to KINGDOM HEARTS III and IV start moving into the foreground.
Image credit: Square Enix / Disney
Dream Drop Distance is not optional story material if you want to understand Kingdom Hearts III. It establishes the power of waking, Xehanort’s Real Organization XIII and several of the rules that drive the final confrontation.
χ Back Cover is equally important for a different reason. It introduces the Master of Masters, Foretellers, Luxu and the ancient Keyblade War. However, it does not contain the complete story of Union χ. We will come back to that shortly.
KINGDOM HEARTS III + Re Mind
The final part of the package contains KINGDOM HEARTS III and its Re Mind expansion, bringing the Dark Seeker Saga to its conclusion.

Do not treat Re Mind as disposable post-game DLC. Its story revisits and expands the climax of Kingdom Hearts III, follows Sora’s attempt to save Kairi and helps explain why the series moves toward Sora’s disappearance and Quadratum afterward.
Does Collection [I–III] include the complete Kingdom Hearts story?
Not quite.
Square Enix understandably presents Collection [I–III] as a way to experience the complete story running from the beginning of Sora’s journey through KINGDOM HEARTS III. For the Dark Seeker Saga, that is a fair shorthand.
But Kingdom Hearts now extends beyond that saga. Several canonical chapters outside Collection [I–III] contain information that becomes increasingly important once you start preparing for KINGDOM HEARTS IV.
| Missing story | In Collection? | Why it matters |
|---|---|---|
| Kingdom Hearts Union χ | No | Expands the ancient era far beyond χ Back Cover: Dandelions, True Darkness, Luxu, Lifeboats and characters now relevant to the next saga. |
| Kingdom Hearts Dark Road | No | Explores young Xehanort, Scala ad Caelum and characters whose importance extends beyond his own saga. |
| Kingdom Hearts Melody of Memory | No | The new ending advances Kairi and Riku’s search for Sora and points directly toward Quadratum. |
| 358/2 Days original gameplay | Story only | The HD movie covers the plot, but the original Nintendo DS game itself is not playable in the collection. |
| Re:coded original gameplay | Story only | Again, the narrative is present as HD cinematics rather than the original playable release. |
The important distinction: χ Back Cover is not a replacement for the entire Union χ storyline. It explains the Foretellers’ side of the ancient conflict, while Union χ continues much further and introduces lore that now matters directly to the future of the series.
KINGDOM HEARTS Missing-Link is a different case. It was intended to add another chapter to the timeline, but development was cancelled before the game received a full release. There is therefore no finished Missing-Link campaign that newcomers need to add to their marathon.
Melody of Memory is still available separately, and you can compare current Kingdom Hearts Melody of Memory offers on G2A.COM.
What order should you play KINGDOM HEARTS Collection [I–III]?
For a first playthrough, do not try to rearrange everything into chronological order. Kingdom Hearts was written around mysteries and reveals, so a release-style order preserves those revelations much better.
Our complete Kingdom Hearts games in order guide explains the logic in detail, but this is the route we recommend for a newcomer:
One small trap is worth pointing out: even if your collection menu makes 358/2 Days look like it should come before Kingdom Hearts II, a first-time player should generally experience Kingdom Hearts II first. Days was released later and explains mysteries that KHII originally expected you not to understand yet.
This might be the best time ever to play the entire Kingdom Hearts series on PC
For years, playing Kingdom Hearts meant following the franchise across PlayStation consoles, Nintendo handhelds, mobile games and later cloud versions. In 2026, the PC situation is dramatically cleaner.
Steam already has KINGDOM HEARTS INTEGRUM MASTERPIECE, which packages the same three major collections found in Collection [I–III]: HD 1.5+2.5 ReMIX, HD 2.8 Final Chapter Prologue and KINGDOM HEARTS III + Re Mind.
On October 8, the new Collection [I–III] also joins the Microsoft Store on Windows, with Xbox Play Anywhere support for the Xbox ecosystem. Meanwhile, Epic Games Store has the major PC releases and, crucially, Melody of Memory, which is currently the easiest native PC route to the post-KHIII chapter that points toward Quadratum.
There is another reason the timing works: KINGDOM HEARTS IV is currently scheduled for late 2027, including PC versions through Steam, Epic Games Store and Xbox on PC. That gives newcomers plenty of time to work through the saga without trying to turn a two-decade RPG story into a two-week homework assignment.

Kingdom Hearts lore: our complete story guide
If you have heard the usual joke that Kingdom Hearts is impossible to understand, do not let it put you off. The story is complicated, but it becomes much easier once the games are put in the right context.
The fastest overview is our Kingdom Hearts Story – Everything You Need to Know. It follows the complete timeline from the ancient Keyblade War to Sora’s disappearance and the road to Quadratum.
For the full version, we split the saga into five dedicated chapters:
Part I – Age of Foretellers, Keyblade War, Simulated Daybreak Town
The Master of Masters, Foretellers, Luxu, χ, Union χ, True Darkness, Dandelions, Lifeboats and the ancient Keyblade War. This is the essential companion piece for the Union χ material missing from Collection [I–III].
Part II – Xehanort Origin, Wayfinder Trio
Dark Road, young Xehanort, Scala ad Caelum, Terra, Aqua, Ventus, Vanitas and the tragedy behind Birth by Sleep.
Part III – Child of Destiny, Memories Lost, One Year of Life
The original Kingdom Hearts, Chain of Memories, Organization XIII, Castle Oblivion, Roxas, Axel, Xion and 358/2 Days.
Part IV – War Against Organization XIII, Artificial Reality, Power of Waking
Kingdom Hearts II, Re:coded, Dream Drop Distance, Xemnas, time travel, the Real Organization XIII and the power of waking.
Part V – Lost in the Realm of Darkness, Final Clash with Xehanort, Searching for Quadratum
0.2 Birth by Sleep, KINGDOM HEARTS III, Re Mind, the defeat of Xehanort, Sora’s disappearance, Melody of Memory and the search for Quadratum.
You can essentially use those five guides as a companion timeline while playing. Whenever the collection suddenly mentions a Dandelion, Replica, Nobody, Foreteller or another version of Xehanort and assumes you remember exactly what that means, the relevant Deep Dive fills in the gap.
Do you need Union χ, Dark Road and Melody of Memory before KINGDOM HEARTS IV?
If you only want to finish Sora and Xehanort’s original conflict, Collection [I–III] already gets you most of what you need.
If your goal is to enter KINGDOM HEARTS IV fully prepared, the answer changes.
Union χ is becoming increasingly difficult to treat as optional
χ Back Cover introduces the Foretellers, but Union χ continues the ancient storyline through the Dandelions, True Darkness, the fall of Daybreak Town and characters who survive into later eras. Recent KINGDOM HEARTS IV material has made those ancient connections more relevant rather than less.
Dark Road explains much more than young Xehanort
Dark Road follows Xehanort’s youth in Scala ad Caelum, but its cast and revelations also help connect the ancient Keyblade era to the characters now appearing around KINGDOM HEARTS IV.
Melody of Memory has a small but important new story chapter
Most of Melody of Memory is a rhythm-game journey through the music and memories of the series. Its ending, however, moves the plot beyond Re Mind. Kairi’s memories provide the breakthrough that leads Riku toward Quadratum, making those final scenes the direct post-KHIII bridge into the next saga.
With KINGDOM HEARTS IV scheduled for late 2027, newcomers now have something the series has rarely offered: a clear catch-up window and a relatively simple modern platform route.
KINGDOM HEARTS Collection [I–III] FAQ
Does KINGDOM HEARTS Collection [I–III] contain every Kingdom Hearts game?
No. It contains the three major collections through KINGDOM HEARTS III + Re Mind, but Union χ, Dark Road and Melody of Memory remain outside the bundle. The playable DS versions of 358/2 Days and Re:coded are also not included.
Can you play 358/2 Days in the collection?
No. Collection [I–III] includes the HD cinematic compilation from 358/2 Days, not a remaster of the original Nintendo DS gameplay.
Can you play Re:coded in the collection?
The original Re:coded game is not playable. Its main story is included as an HD cutscene compilation inside HD 1.5+2.5 ReMIX.
What is the easiest way to play Kingdom Hearts on PC?
KINGDOM HEARTS INTEGRUM MASTERPIECE on Steam combines HD 1.5+2.5 ReMIX, HD 2.8 Final Chapter Prologue and KINGDOM HEARTS III + Re Mind. You can then add Melody of Memory through Epic Games Store and catch up on Union χ and Dark Road through their complete story material.
One collection gets you most of the way, but not all the way
KINGDOM HEARTS Collection [I–III] is about as close as this famously scattered series has ever come to a single clean starting point. You can begin with Sora on Destiny Islands and work through the major games, prequels, movies and bridge chapters until the final battle with Xehanort without constantly changing hardware.
Just do not mistake “I–III” for “literally everything.” The ancient story in Union χ, Xehanort’s youth in Dark Road and the post-KHIII ending of Melody of Memory increasingly matter as the Lost Master Arc begins.
For PC players in particular, that makes late 2026 an unusually good moment to start. The major saga is readily available, the remaining story gaps can be filled in, and there is still time to make sense of hearts, Nobodies, Foretellers, replicas, sleeping worlds, time travel and several generations of Keyblade wielders before KINGDOM HEARTS IV arrives in late 2027.
