What the Kingdom Hearts Collection I–III Is and When It Releases
Kingdom Hearts Collection [I~III] is an all-in-one bundle that collects the mainline Kingdom Hearts saga in a single release, offering newcomers and long-time fans a streamlined way to play nearly the entire story of Sora and his friends on modern platforms with native (non-cloud) versions of every included title. Square Enix has confirmed that the Kingdom Hearts Collection [I~III] launches on October 8 for Nintendo Switch 2, PlayStation 5, Xbox Series X|S and PC via the Microsoft Store on Windows, with Kingdom Hearts Collection pre-order options now live across all platforms. According to Square Enix’s official announcement, the compilation aims to give players “a streamlined, all-in-one bundle” that spans from the original Kingdom Hearts through Kingdom Hearts III + Re Mind. This timing sets the stage for new and returning players to catch up before Kingdom Hearts IV arrives on the same hardware generation.
All Games Included in Kingdom Hearts Collection I–III
The Kingdom Hearts Collection [I~III] groups together three major compilations: Kingdom Hearts -HD 1.5+2.5 ReMIX-, Kingdom Hearts HD 2.8 Final Chapter Prologue, and Kingdom Hearts III + Re Mind (DLC). Across these, players get Kingdom Hearts Final Mix, Re:Chain of Memories, Kingdom Hearts II Final Mix, 358/2 Days (HD cutscenes), Birth by Sleep Final Mix, and Re:coded (HD cutscenes) from the first package. HD 2.8 adds Dream Drop Distance HD, the χ Back Cover movie, and 0.2 Birth by Sleep. The final part, Kingdom Hearts III + Re Mind, includes the complete third numbered entry and its story-expanding DLC. All three sets are digital, while the full Kingdom Hearts Collection [I~III] will be available both physically and digitally. For those who prefer to build their library piecemeal, each component set can also be purchased separately on supported platforms.
Platforms, Pre-Order Choices, and the New Native Switch Version
Kingdom Hearts Collection pre-order options cover a wide range of platforms. On Nintendo Switch 2, PlayStation 5, Xbox Series X|S and PC via Microsoft Store, players can either pre-order the full Kingdom Hearts Collection [I~III] bundle or opt for individual digital compilations: Kingdom Hearts -HD 1.5+2.5 ReMIX-, Kingdom Hearts HD 2.8 Final Chapter Prologue, and Kingdom Hearts III + Re Mind. A notable change for long-time handheld and hybrid fans is that Kingdom Hearts -HD 1.5+2.5 ReMIX- will be available natively on Nintendo Switch (not just via cloud streaming), finally bringing the early saga directly onto the system. Square Enix also notes that certain purchases will include platform-exclusive in-game items, although full details on those bonuses are still to come. If you are aiming to play everything in release order, securing the full bundle on your main platform is the simplest route.
Free Kingdom Hearts III + Re Mind Demo on Nintendo Switch 2
Alongside the collection announcement, Square Enix has released a free demo for Kingdom Hearts III + Re Mind on Nintendo Switch 2 that can be downloaded today. The demo is split into two distinct parts aimed at both first-time and returning players. The first segment covers the beginning of Kingdom Hearts III through the early stages of Olympus, the world inspired by Disney’s Hercules, and progress from this section will carry over to the full game at launch. The second segment runs from the start to the middle of Toy Box, the Toy Story-inspired world created with Disney and Pixar, though save data from this portion will not transfer. This structure lets curious players test performance and combat on Switch 2, while also giving story-focused fans a head start on Sora’s latest numbered adventure if they decide to buy the full release later.
What the New Kingdom Hearts IV Trailer Reveals and Why the Timing Matters
During the recent Nintendo Direct announcements, Square Enix premiered a new Kingdom Hearts IV trailer, confirming that the next mainline game is in development for Nintendo Switch 2, PlayStation 5, Xbox Series X|S and PC. While Square Enix has not yet supplied a launch window, the trailer’s arrival alongside the October 8 release date news for the collection clearly sets up a roadmap: one package to bring everyone up to speed, and another journey on the horizon. The June 2026 trailer, now online, focuses on teasing the next chapter rather than explaining it, with Square Enix stating that “more details about the game will be revealed in the future.” For fans, this means the best way to prepare for Kingdom Hearts IV is to work through the Kingdom Hearts Collection [I–III] as it hits current platforms later this year.
