World of Slime Supported Languages
All eighteen interface and subtitle languages on the Steam listing, how to change language on PC, what is missing, and what players say about translation quality.
World of Slime is unusually generous with localisation for a game of its size. The Steam demo listing publishes eighteen supported languages for interface and subtitles, which is more than most Korean casual MMOs offer at launch and a clear signal that TEAM42 is targeting a global audience rather than a domestic one first. This page lists them, explains how to switch, and covers the quality question honestly.
The Full Language List
As listed on the Steam demo page, interface and subtitles are available in English, Korean, Japanese, Traditional Chinese, Arabic, Brazilian Portuguese, French, Italian, German, Spanish (Spain), Latin American Spanish, Russian, Vietnamese, Ukrainian, Indonesian, Thai, Turkish, and Polish. That is eighteen entries in total.
No language has full voice audio. Every entry is interface plus subtitles, so the game’s dialogue is read rather than spoken regardless of which language you pick. Given how wordy demo players find the dialogue, that is worth knowing before you start.
Two things stand out on that list. Spanish appears twice, split into European and Latin American variants, which is a meaningful investment rather than a token gesture. And the presence of Arabic, Thai, Indonesian, and Turkish alongside the usual European set suggests the mobile launch is aiming at markets that PC-first releases often skip. Our mobile page covers what is known about that release.
How to Change Language on PC
On Steam the reliable method is the client rather than the game. Right-click World of Slime Demo in your library, open Properties, and set the language there before launching. Steam will then pull the appropriate localisation on next start. If the game is already running, close it completely before switching so the change takes effect on a clean start.
The demo also exposes language selection inside its own options menu on most builds. If both are set and they disagree, the in-game setting is the one to trust for the interface you actually see. Should text render as boxes or blanks after a switch — most likely with Arabic, Thai, or Ukrainian — restart the client before assuming a bug; our troubleshooting page collects the display problems players have reported.
Mobile Language Support
The December 2026 mobile release has not published its own language list, and no iOS or Android store page exists yet. It is reasonable to expect the mobile client to broadly match the PC list given the shared cross-play design, but this wiki will not state that as fact until a store listing confirms it. Watch the roadmap for the pre-registration wave in November 2026, which is when store metadata usually appears.
Translation Quality: An Honest Note
This is where the list stops being purely good news. TEAM42’s AI content disclosure on Steam states that core languages were translated by its team while additional languages use AI-assisted translation. The studio does not say which languages fall into which bucket.
English-speaking demo players have been vocal that dialogue and item descriptions frequently read awkwardly, with several reviewers describing the text as under-edited rather than incomprehensible. Whether English counts as a core language or an AI-assisted one is not disclosed. If you are comfortable in more than one supported language, it is genuinely worth trying a second one and seeing which reads better for you — this is a case where the community has no consensus and your own eyes are the best test. Our AI generated content page sets out the disclosure in full.
What This Wiki Covers
This wiki is published in English, French, German, and Spanish. That is deliberately narrower than the game’s list: we write and localise every page by hand rather than machine-translating it, so we cover the languages we can maintain at depth instead of shipping eighteen shallow copies. Every guide, FAQ, and internal link on this site is written natively in each language, and pages are updated together rather than left to drift.
If you play in a language we do not cover, the English pages are the most complete and are updated first. Terminology on this site follows the in-game English wording where a stable translation exists, which should make cross-referencing straightforward even if your client is set to Thai or Polish.

For platform and hardware questions see platforms and system requirements. For accessibility features including Camera Comfort, custom volume controls, and the touch-only option, see accessibility — several of those settings matter more than language choice if you found the demo uncomfortable to read or hear. And if you are just starting, getting started walks through the opening hour in whichever language you have chosen.
