Ratatan will leave Early Access and reach version 1.0 on October 15, 2026. Ratata Arts’ rhythm roguelite action game is scheduled for PC, Nintendo Switch 2, PlayStation 5 and Xbox Series X|S, with its full-release update bringing the last announced story content, a final-world encounter and newly recorded orchestral music.
The headline additions are Chapters 3 and 4, which complete the game’s chapter lineup, plus a final world and an ultimate boss. The 1.0 build will also unite the Dark Ratatans that have appeared previously. That makes the update more than a routine version-number change: it is positioned as the point at which the Early Access project becomes the completed game.
What Ratatan 1.0 adds
The most concrete gameplay news is the arrival of two new chapters. For players who have held off until the game’s full structure was in place, Chapters 3 and 4 are the major reason to pay attention to the October launch. They lead into a final world and an ultimate boss, while the Dark Ratatans are set to come together in the completed release.
Ratatan is described as a rhythm roguelite action game. “Rhythm” signals that timing and music are central to play, while “roguelite” generally describes a run-based format built around repeat attempts and persistent elements rather than one uninterrupted campaign. The announced information does not spell out the exact structure of the new chapters or the ultimate boss fight, so players should avoid assuming details about mechanics, progression requirements or difficulty until the full update notes arrive.
Those notes are planned for the day before launch. They are expected to cover additional features and quality-of-life changes, but their precise contents have not yet been detailed. Quality-of-life improvements are usually changes intended to make a game clearer, smoother or less cumbersome without necessarily changing its core challenges. In Ratatan’s case, the October 14 notes should be the useful reference point for players deciding whether a particular issue, request or interface concern is addressed in 1.0.
Live orchestra recordings are joining the game
A live orchestral recording has been completed for Ratatan, and the resulting tracks are due to be integrated into the 1.0 release. This is a particularly natural fit for a game whose identity is rooted in rhythm: music is not simply background flavor when it is part of the experience’s central genre label.
The announcement confirms the recordings and their inclusion, but does not identify individual compositions, orchestral performers, in-game scenes, or whether every existing musical piece is being replaced or supplemented. The safest expectation is therefore the stated one: orchestral tracks will be present in the launch build, with fuller implementation detail still to come.
For a rhythm-led game, a new score can have practical implications beyond atmosphere. Timing-based experiences benefit from clear musical cues and a strong sense of momentum, and orchestral arrangements can change the texture and dramatic weight of those cues. Whether that changes gameplay timing itself is unknown, however, and should not be presumed from the recording news alone.
Console pre-orders, prices and the early-purchase weapon
Digital console pre-orders opened on September 16, 2026. A 10% pre-order discount applies through the official October 15 release date.
- Digital Standard Edition: $34.99 regular price; $31.49 during the stated pre-order discount.
- Digital Deluxe Edition: $39.99 regular price; $35.99 during the stated pre-order discount.
- Physical Edition: $39.99 suggested retail price.
The Digital Deluxe Edition is listed with the game, the early-purchase bonus, a Special Weapon & Accessory Pack, Cobun Pack and Supplies Set. The announcement names those components but does not provide an item-by-item breakdown of the packs or set. As a result, prospective buyers can clearly distinguish the editions by their listed bundled content, but cannot yet assess every individual extra from the information available.
All console pre-orders include the legendary weapon Spirit Sword Banbansord as an early-purchase bonus. Qualifying Steam Early Access owners will receive it automatically when the official launch arrives. The Deluxe Edition DLC is also planned to become available separately for Steam Early Access players beginning on release day.
That distinction matters for people already playing on PC. The weapon bonus is not described as requiring a separate redemption step for qualifying Steam Early Access purchasers; it will be added at launch. Meanwhile, Deluxe-related content is framed as separately purchasable DLC on October 15, rather than an automatic upgrade for every existing PC owner.
There is a broader purchasing consideration here, too. Ratatan will have physical and digital options, but the supplied details only establish a suggested price for the physical edition, not its retailer list, regional availability or platform-specific stock. Anyone specifically seeking a boxed copy should treat $39.99 as the stated suggested retail price rather than a guarantee of local availability.

Platforms, modes and language support
Ratatan 1.0 is scheduled for PC, Nintendo Switch 2, PlayStation 5 and Xbox Series X|S. It supports one offline player and one to four online players. The separate offline and online figures are important: local play is listed as single-player, while multiplayer is specifically an online option for up to four participants.
The listed ESRB rating is E10+, meaning Everyone 10+. Language support includes Simplified Chinese, Traditional Chinese, Japanese, Korean, English, French, German, Italian, Portuguese (Portugal) and Spanish.
The combination of a solo offline option and online support for up to four people gives the release a fairly clear practical outline. A player who wants to engage alone can do so without relying on online party formation, while groups should note that the cited multiplayer capability is online rather than local. Specific matchmaking options, cross-platform play and platform-account requirements have not been detailed.
Tokyo Game Show appearance comes before launch
Ratatan will appear at Tokyo Game Show 2026 from September 17 through September 21, at the Game Source Entertainment booth in Hall 2, Booth 02-N02. The booth will have demo stations, limited novelties while supplies last, and a limited-edition RATATAN ID Card.
The ID Card is randomized and is awarded to visitors who fulfill specified conditions at the booth. The exact conditions and potential card variants are not outlined in the available information. That means attendees interested in the card should be prepared for a limited, event-specific distribution rather than assuming it is a general purchase bonus or a guaranteed item for every visitor.
The show appearance lands less than a month before the full release. It gives Tokyo Game Show attendees an opportunity to see Ratatan in person ahead of the October 15 version 1.0 launch, while the broader audience awaits the detailed patch notes scheduled for the preceding day.
What remains to be clarified before October 15
The full-release outline is now firm: the date, platforms, new chapters, final world, ultimate boss, Dark Ratatan gathering, orchestral tracks, edition prices and early-purchase bonus have all been specified. Several useful details remain pending, most notably the complete update notes and a fuller description of the Deluxe extras.
Players interested in the content itself should watch for the final patch documentation, especially for feature-level changes and quality-of-life adjustments. Buyers deciding between editions have the core comparison now: the Standard Edition supplies the game and applicable early-purchase weapon, while Deluxe adds the Special Weapon & Accessory Pack, Cobun Pack and Supplies Set. Existing qualifying Steam Early Access players, meanwhile, can expect Spirit Sword Banbansord to be added automatically at the official launch and can purchase the Deluxe DLC separately that day.
With Chapter 3, Chapter 4, a final world and an ultimate boss all arriving together, Ratatan’s October update is designed to mark the transition from evolving Early Access release to finished rhythm roguelite action game. The orchestra is tuning up, the Dark Ratatans are apparently organizing, and the final boss is waiting with the sort of confidence that suggests it has not read the patch notes either.
