Eleven languages

Quick answer

Eleven languages at launch is unusual for a three-person studio, and the developer explained how they did it in the release announcement.

Eleven languages at launch is a lot for a small studio, and the way they did it is the interesting part.

Spanish is listed as Latin America specifically, which matters if you are looking for European Spanish. European Spanish is not listed separately.

Line by line, then played

The launch announcement makes a claim worth repeating because it is unusual: every language was reviewed line by line, and people played through the game in them before release.

Stronger than "localised into ten languages". Line-by-line review plus a playthrough in each language is the expensive version of localisation, and the announcement frames it as a deliberate choice: "We did this one properly rather than quickly."

The launch announcement names ten: English, Portuguese, French, Italian, German, Spanish, Japanese, Korean, Russian and Simplified Chinese. The store listing shows eleven, with Traditional Chinese on the end. It was not a later addition either, since a 4 November patch was already fixing a Traditional Chinese-specific bug three days after release.

Two dates explain the shape of the list. The 20 October demo update added French, German, Italian, Japanese, Korean, Russian, Simplified Chinese and Spanish, making eight on top of the original Portuguese and English. Then the launch build carried the full set.

Chinese recipes, 4 November

On 4 November a patch fixed an issue where craftable items were not appearing correctly at the sewing table when playing in Traditional Chinese. A specific, reproducible, language-only bug: the sewing table's recipe list was incomplete for that locale.

Traditional Chinese on a build older than 4 November had a sewing table missing recipes, and that gap is closed.

The same patch cycle renamed the exit button to Exit and Save, adjusted the hunting reticle and fishing bar per difficulty, fixed the travel map sending players to Hunting Island, and fixed deer surviving a spear hit on Hard. It was a substantial patch and the Traditional Chinese fix was one line in it.

Recipe lists are UI

Because the game is a survival game with a lot of item names, recipe lists and interface text. A player who cannot read the recipe list cannot play efficiently, which is why the sewing table bug was serious rather than cosmetic.

Eleven languages also means the player base is not English-only. Reviews and discussions happen in Portuguese, Japanese and Chinese as well as English, and the developer reads the community across all of them — the launch announcement asks players to report anything that reads oddly in their language, promising a fix.

No credits, no roadmap

No translation credits, no list of which languages got a full playthrough versus a review pass, and no announcement about further languages. The store list is the authoritative source and it currently shows eleven.

Deciding which language to play in? A listed language is covered by a review process the studio describes as line-by-line. An unlisted language leaves English, the base language the game was written in.

Checking your own language

Four steps, and they take about a minute.

Open the store page and find the language block. It lists eleven and it is the only authoritative source, because it is generated from the same data the client uses.

A language on the list is covered by the review process the launch announcement describes. If it is not, the game will run in English, which is the language it was written in.

Then check the version. A Traditional Chinese player on a build older than 4 November had a sewing table with missing recipes, and that is the kind of bug that reads as a broken game rather than a translation problem. Fixed, and the fix is the reason the language block is worth checking alongside the version number.

If something reads oddly, the launch announcement asks you to say so and promises a fix. Not a formality: the Traditional Chinese sewing table fix came four days after launch, which is evidence that reports reach the people who can act on them.

Eleven languages from a small team

Portuguese is the studio's own language, so it is the one language in the list that certainly had a native speaker on the team. English is the base the game was written in, per the launch announcement's phrasing. The other nine arrived through a localisation effort the studio describes as line-by-line review plus a playthrough.

That matters for a specific kind of player: the one who wants to play in their first language and has been burned by machine-translated survival games where item names do not match the crafting menu. Eleven reviewed languages is unusual at this price and from a team this size, and it is one of the few things about the launch that went right the first time.

Why this site is English

This site is English only. A choice about where the search demand is, not a statement about the game. Players looking for a guide in Portuguese, Japanese or Chinese will find the game fully playable in their language even if the guide is not.
