Ratatan 1.0 Sets October Launch With Final Chapters and Orchestral Music

Ratatan will leave Early Access and reach its full 1.0 release on October 15, 2026. Developed by Ratata Arts and published globally by Game Source Entertainment, the rhythm roguelite action game is scheduled for PC, Nintendo Switch 2, PlayStation 5, and Xbox Series X|S.

The version 1.0 update is positioned as the game's completion milestone. Its headline additions are Chapters 3 and 4, a final world, and an ultimate boss encounter. The launch build will also bring together the Dark Ratatans that have appeared previously, while a newly recorded orchestral soundtrack will be incorporated into the game.

Console digital pre-orders opened on September 16, 2026. A 10% pre-order discount is available through the October 15 release date, and an early-purchase weapon bonus will be offered to console pre-order customers as well as eligible Steam Early Access players.

Ratatan 1.0 completes the Early Access journey

Ratatan's upcoming 1.0 update is more than a routine content drop. Ratata Arts is treating it as the end point of the game's Early Access phase, with the final pair of chapters intended to round out the available adventure. Chapters 3 and 4 are the major new additions, leading into a final world and the ultimate boss.

That structure suggests October's build will give players a clearer complete-game arc, rather than simply expanding the pool of replayable content. As a rhythm roguelite action title, Ratatan's identity rests on the combination of musical timing, action-focused play, and the repeat-run framework associated with roguelite design. The final chapters and boss are therefore significant not only as additional destinations, but as the material meant to close the game's progression path.

The announcement also confirms that the Dark Ratatans seen during the game's development will be brought together in the 1.0 version. Specific details about their role in the final release have not been outlined, but their inclusion is being highlighted alongside the climactic world and boss content.

Players waiting for a complete overview of the update will need to wait a little longer. Detailed patch notes, covering the broader feature list and quality-of-life changes, are planned for publication one day before launch. Those notes are expected to clarify the many smaller refinements arriving alongside the new chapters.

A live orchestra joins Ratatan's launch build

Music is naturally central to a game built around rhythm, and Ratatan's 1.0 release will expand that side of the experience with orchestral recordings. A live orchestral recording session has been completed, and the resulting tracks are set to be integrated into the game at launch.

This is a meaningful addition for a title whose gameplay and presentation are tied so closely to sound. The announcement does not state exactly where each orchestral track will play, whether the arrangements replace existing pieces, or how extensive the orchestral selection will be. What is confirmed is that the recordings are part of the 1.0 package and will arrive with the October release rather than as a later update.

Combined with the final chapters, the new music gives the full release a more celebratory shape. It also makes the launch more than a simple platform expansion: returning Early Access players will have major new story-facing content, a final confrontation, the gathering of the Dark Ratatans, and a newly recorded orchestral component to look forward to.

Console pre-orders, editions, and early-purchase rewards

Digital pre-orders for Nintendo Switch 2, PlayStation 5, and Xbox Series X|S are now available. The Standard Edition is listed at USD 34.99, falling to USD 31.49 during the 10% pre-order promotion. The Digital Deluxe Edition is listed at USD 39.99, with the discounted pre-order price set at USD 35.99.

The discount runs until Ratatan officially launches on October 15. The announcement also lists a Physical Edition with a suggested retail price of USD 39.99. Availability and regional retail specifics for physical copies were not detailed.

All qualifying console pre-orders receive the legendary weapon Spirit Sword Banbansord as an early-purchase bonus. The same weapon will also be granted to qualifying purchasers from Ratatan's Steam Early Access period. For those players, the item will be automatically added to the game when the official release arrives.

The Digital Deluxe Edition includes several extras beyond the base game and early-purchase weapon:

• The Ratatan base game
• The Spirit Sword Banbansord early-purchase bonus
• A Special Weapon & Accessory Pack
• A Cobun Pack
• A Supplies Set

Steam players should note that the Deluxe Edition DLC is planned to become available as a separate purchase on October 15. This means Early Access players are not required to buy a new edition of the game to obtain the launch-day DLC, though the package itself will be sold separately after release.

Tokyo Game Show demo plans

Ratatan is also due to appear at Tokyo Game Show 2026, which runs from September 17 through September 21. The game will be featured at the Game Source Entertainment booth in Hall 2, Booth 02-N02.

Attendees will be able to try the game at demo stations during the event. The booth is also set to hand out limited novelties while supplies last. Visitors who fulfill specified conditions at the booth can receive a randomized limited-edition RATATAN ID Card.

For Ratata Arts, the timing creates a useful final showcase immediately before the full version's arrival. Tokyo Game Show takes place less than a month ahead of launch, offering prospective console players and interested newcomers an opportunity to get hands-on with the rhythm roguelite before its complete release.

Platforms, modes, and language support

Ratatan will support one player offline and between one and four players online. The confirmed 1.0 launch platforms are PC, Nintendo Switch 2, PlayStation 5, and Xbox Series X|S. No versions for other Nintendo, PlayStation, Xbox, handheld, or mobile systems have been announced in this release information.

The game carries an ESRB 10+ age rating. Its stated language support includes Simplified Chinese, Traditional Chinese, Japanese, Korean, English, French, German, Italian, Portuguese as used in Portugal, and Spanish.

That breadth of language support, together with simultaneous plans for PC and three console families, underlines the global focus of the 1.0 rollout. It is also notable that Nintendo Switch 2 is among the confirmed versions, placing Ratatan on Nintendo's newer hardware rather than listing the original Switch in its platform lineup.

What to expect before October 15

There are still a few open questions surrounding Ratatan 1.0. The planned day-before-launch update notes should be the next key information drop, especially for players interested in the announced quality-of-life changes and the full list of new features. They may also offer more context for Chapters 3 and 4, the final world, the ultimate boss, and how the Dark Ratatans fit into the completed game.

For now, the broad outline is clear: Ratatan reaches 1.0 on October 15, 2026, ending its Early Access phase with its final chapters, a concluding world and boss, assembled Dark Ratatans, and orchestral tracks recorded specifically for this release. Console pre-orders are live with a limited 10% reduction in price, while existing eligible Steam Early Access players are set to receive the Spirit Sword Banbansord automatically at launch.

With a Tokyo Game Show presence immediately ahead of release and four confirmed platforms for the full version, October is shaping up to be the game's most substantial moment yet.
