Mouthwashing on Game Pass: release date and platforms

Mouthwashing is coming to Xbox Game Pass on October 29, 2026. The announcement covers cloud, Xbox Series X|S, handheld devices, and PC. The listed memberships are Game Pass Ultimate, Game Pass Premium, and PC Game Pass. This is the game’s arrival on Microsoft’s service, not its original release: the PC edition launched on Steam on September 26, 2024.

When Mouthwashing arrives on Game Pass

The official date is October 29, 2026, according to the Xbox Wire announcement for October’s second wave. As of October 26, this article’s publication date, the addition is therefore still scheduled for the future.

The title appears alongside other games planned for the same day, but the announcement gives no release time. It is also unwise to assume access will begin simultaneously in every territory, since catalogs and availability may vary. Check the service’s official page for your region before installing.

One more distinction matters. Xbox Wire says developer Wrong Organ and publisher Critical Reflex are bringing the game to Game Pass, but does not mark it as a day-one release. That is consistent with Mouthwashing having already been available on PC for more than two years.

Announced platforms and memberships

The official list names four access categories: Cloud, Xbox Series X|S, Handheld, and PC. Xbox Wire’s own note says the “Handheld” designation represents games optimized for handheld play. It does not name specific devices, so the category should not be treated as confirmation for any individual model.

The memberships associated with Mouthwashing are Game Pass Ultimate, Game Pass Premium, and PC Game Pass. Game Pass Essential does not appear on the game’s listing. Anyone planning to use cloud play or a handheld should check the Xbox app or website to confirm that the feature, membership, and territory are compatible on release day.

The announcement names only Xbox Series X|S among consoles. It does not confirm an Xbox One edition. Likewise, the supplied sources do not support availability on PlayStation or Nintendo Switch. The safest approach is to separate platforms explicitly listed by Xbox from requested or rumored versions.

What Mouthwashing is

The Critical Reflex page describes Mouthwashing as a narrative-driven, first-person horror game. Its story follows the five crew members of the Tulpar, a wrecked space freighter left isolated in space. Starvation, confinement, and the crew’s deteriorating relationships drive the tension.

The experience asks players to watch their surroundings and small details while dealing with unreliable perception and psychological horror. It is not presented as an open-ended space exploration game or a cooperative experience. Steam lists it as single-player.

New players should also consider its subject matter. The developers’ mature-content description mentions extreme violence, gore, and mutilation involving characters styled after the original PlayStation era. That warning is more useful for deciding whether the game is appropriate than revealing specific plot events; avoiding extensive summaries can preserve the intended narrative construction.

Original release and language support

The Mouthwashing Steam page records a September 26, 2024 release, developed by Wrong Organ and published by Critical Reflex. October 29, 2026 is therefore the announced Game Pass debut, not the game’s first publication.

On Steam, interface text and subtitles are available in 16 languages, including English, French, Brazilian Portuguese, and Spanish from Spain. Full audio is listed only in English. These details belong to the edition sold through that store; the supplied sources do not separately document the languages of every Xbox ecosystem edition. Check the intended version’s listing before downloading.

The Steam edition also supports achievements, trading cards, and Family Sharing. These features should not be treated as confirmation of Xbox equivalents, since each storefront maintains its own product information and infrastructure.

PC requirements listed by Steam

For the Steam edition, minimum requirements list an i5-6300HQ processor, 8 GB of memory, a GTX 560, DirectX 11, and 3 GB of available storage. The recommended configuration lists an i5-1135G7, 16 GB of memory, a GTX 1050, DirectX 11, and the same 3 GB of storage.

Although both configurations still name 64-bit Windows 7, the page also warns that the Steam client has supported only Windows 10 and later since January 1, 2024. PC Game Pass users should consult the requirements shown in the Xbox app, because Steam’s figures do not prove that another distribution has identical requirements.

What to verify before playing

In short: the announced date is October 29; the listed options are cloud, Xbox Series X|S, handhelds, and PC; and the memberships are Ultimate, Premium, and PC Game Pass. No release time is provided, and the available sources do not confirm Xbox One, PlayStation, or Switch versions.

Because catalogs, compatibility, and features can change, use the official Xbox announcement as a starting point and verify the regional game listing before subscribing or downloading. That keeps the service debut distinct from the original 2024 release.
