Order of the Sinking Star Achievements Guide

The honest state of play on September 24, 2026 is narrow: Order of the Sinking Star has achievements, and nobody outside Thekla knows what they are. No names, no icons, no counts. This page explains what is confirmed, what is not, and what happens next.

Quick Answer

Steam Achievements are confirmed for Order of the Sinking Star through the store’s own structured feature data. The achievement list is not public. Pre-release Steam titles do not expose their achievement schema, so no list, count or icon set can be verified before the game unlocks on October 8, 2026. This page records the confirmed facts and will be completed at launch.

[!warning] Any specific achievement name or total you see for this game before launch is unverified. There is no official list to compare against yet, and this page will not guess at one.

What is confirmed

The confirmed facts are short enough to fit in a table, which is the point.

Official source: Order of the Sinking Star on Steam

The platform picture around this matters slightly. The game ships on Windows, PlayStation 5 and Nintendo Switch 2. There is no Xbox version, no Game Pass version, no Switch 1 version and no PS4 version, so if you are a console player chasing achievements, the PS5 trophy list is the relevant one, and it is equally unpublished.

Other launch-time unknowns sit in the same category, and they are worth listing here because they get mistaken for achievements information. System requirements for both the full game and the demo still read as TBD, with no official numbers published. The Nintendo Switch 2 version has a listed download size of 18.4 GB and carries an ESRB rating of Everyone with Mild Fantasy Violence. Those are the concrete pre-launch specifications that exist; the achievement list is not among them.

How we checked, and the limit of that check

Because “no achievements exist” and “achievements exist but are not published” are very different claims, it is worth being explicit about the evidence behind the second one. Three signals were checked directly on September 24, 2026.

Steam’s store API returns achievements: null for AppID 499170 — the field exists but carries no data, which is what an unreleased app looks like. Steam’s own community stats endpoint for the app returns “No stats are available at this time”. PlayStationTrophies, which tracks trophy sets ahead of release when they are submitted, states that the trophy list has not been released.

[!note] One honest limit: SteamDB and SteamHunters, the two third-party databases that often surface a list early, could not be reached from the machine used for this check — both returned HTTP 403 behind Cloudflare. The conclusion that no list is public therefore rests on the three primary signals above, not on a clean sweep of every database. If either site publishes a list before launch, it will be linked here rather than guessed at.

The consequence of all this is simple. A pre-release page that lists achievements for this game is either guessing or republishing something unverifiable, and both are worth distrusting. There is no partial version of the truth to report, and no example names are offered here on purpose: inventing even one plausible-looking name would be worse than leaving the field empty.

Why the list is not public yet

This is worth explaining, because “no list” and “hidden list” are different things and the difference is not a marketing decision.

Steam’s store API exposes a game’s feature flags — including whether achievements are supported — before release. It does not expose the achievements themselves. The achievement schema is generated from the app’s backend configuration and becomes readable once the app goes live, which is exactly why the field comes back as null rather than as an empty list. That is true for essentially every unreleased Steam title, not a special case for this game.

The list arrives complete or not at all, which is why the confirmed table above contains feature flags and check results rather than names.

There is also a version-scope question that will not be answerable until launch. The demo is a separate Steam app with no achievements of its own, and the official announcement states that progress made in the demo carries over to the launch version. There is no demo achievement state to include in that transfer, but whether completing demo content will unlock achievements in the launch build has not been described. If you are the sort of player who cares, the safe assumption is that you will need to earn anything achievement-related in the full release.

[!note] The demo’s own app is separate from the full game’s app, and it has no achievements at all. Anything you read about “demo achievements” for this game is describing a feature that does not exist on the demo’s store listing; the full game’s list is the only one to watch.

How achievements usually work in a game like this

The following is general Steam behaviour rather than information about this specific game, and it is offered so you can plan rather than speculate.

Steam achievements are granted by the game itself, through the Steamworks API, at moments the developer chooses. They are stored on your Steam account and sync through Steam Cloud, which is why a cloud save and an achievement list often disagree in games where progress is tracked in the save file: the achievement is a one-way event, not a saved state. Family Sharing lets another account play your library, but achievement behaviour under sharing varies by game and is set by the developer.

The technical shape of a grid puzzle game also constrains what its achievements can realistically be. There are usually three families. Progression achievements fire as you advance — entering each world, opening each gateway, reaching the point where the worlds collide. Collection achievements track optional finds such as audio logs and environmental lore, which this game has in quantity and which are described as clues rather than decoration. Completion achievements track puzzle-solving totals, and those are the ones that get interesting in a game whose published scale runs past a thousand puzzles.

Because the number of puzzles is so far beyond a normal completion target, any completion-flavoured achievement is likely to be calibrated to a meaningful subset rather than to every board. That is an expectation, not a fact.

What the list will probably look like

Everything in this section is speculation, clearly labelled. It is a framework for reading the list when it appears, not a claim about its contents.

The reason to expect a mix of progression and completionist goals is structural. A game with over a thousand hand-crafted puzzles and a free-roam hub has obvious progression milestones to hang achievements on, and the three-layer narrative provides natural narrative beats. At the same time, the developer has been explicit that the story does not require solving everything, which means a completionist achievement cannot be the critical path — it has to be a deliberately optional target.

The one thing not to expect is a long tail of joke or gimmick achievements. Nothing in the official material suggests that tone, and a game built from four designers’ puzzle systems has a natural vocabulary of mechanical milestones to draw on instead.

Should you plan a completionist run before launch?

No. There is nothing to plan around yet.

Two pre-launch decisions are reasonable in the meantime. First, if you care about achievements, decide whether to keep demo progress. The demo carries over officially and has no achievements of its own, but whether playing it unlocks anything at launch is unconfirmed, so a fresh launch save gives you a clean, unambiguous run. Second, do not chase a puzzle count you read on a store page. The store description of over 1000 interconnected puzzles and Blow’s quoted figure of more than 1400 are different claims, and the achievement-relevant subset is unknown either way.

If you are planning what to do in your first hours regardless, the beginner tips page covers the opening loop, and the Overworld map guide covers the structure achievements are most likely to follow.

What this page will contain at launch

When the game unlocks on October 8, 2026, this page will be rebuilt with the real list: every achievement name, its official description, whether it is hidden, and a short note on how each one is earned. The progress and completion categories will be replaced with the actual split, and the speculation table above will be deleted rather than left standing next to verified data.

Until then, the confirmed facts are the four feature flags at the top of this page and the October 8 date. Nothing else about achievements is knowable.
