Current Turkish-language status
The live Steam language table supplied for Mortal Shell II does not list Turkish interface text, full audio, or subtitles. The game lists 15 supported languages, with English full audio and multiple subtitle/interface translations, but Turkish is not among them.
What the pinned discussion means
The Steam community forum contains a developer-pinned localization request megathread. Turkish players have used it to request subtitles and explain the value of a translation.
That thread confirms community interest; it does not confirm that a Turkish patch is approved, in production, or scheduled. A plus-one comment or reply count is not a release note.
Official patch versus fan translation
An official language update should appear in the Steam language table, game update history, or a developer/publisher announcement. A fan translation is separate software and needs its own compatibility and safety assessment.
Before installing a community patch:
- verify the author and release page;
- scan files and avoid installers that request unrelated permissions;
- check compatibility with the current game build;
- back up changed files and know how to restore them through Steam;
- do not enter Steam credentials into a patch installer.
How this page will be updated
The answer changes only when the official language list or release notes change. Community requests remain labelled as requests until an official source confirms Turkish support.
Short answer
There is no confirmed official Mortal Shell II Turkish patch in the reviewed Steam listing. Turkish localization is a visible community request, not a published feature.
