Sea of Remnants, the new project from Identity V developer Joker Studio, is holding a closed beta test called the Dawnbreaker Test from Friday, December 4 through Friday, December 18, 2026. Preloading opens on Tuesday, December 1.
The supported platform list is broad: PC (Windows), PS5, Xbox Series X, iOS and Android. Japanese is supported in both text and voice. Where the previous Wanderer Alpha Test was PC (Steam) only, this round widens out to consoles and phones.
There is one thing worth checking before you sign up. Play data from the test will be deleted once it ends, and nothing carries over to the full release. This is not a test for people who want to keep their progress.
You play a doll-like voyager who has lost their memories, sailing between islands in a turn-based roguelike adventure. Here is everything known so far, from how to sign up to who can get in.
When is the Dawnbreaker Test, and which platforms are supported?
The test runs for roughly two weeks, from Friday, December 4 to Friday, December 18, 2026. Preloading begins on Tuesday, December 1.

Two weeks feels about right for a roguelike test. Runs are short in this genre, so if you want players stacking up attempts and exploring the breadth of the builds, you need a window that covers two weekends.
Since the previous alpha was PC (Steam) only, this is the first time PS5 and phones are in the mix. A turn-based design that rarely demands split-second timing translates to mobile without compromise. Read it as the studio moving into testing with multiplatform as the baseline assumption.
How do you get in? Entry requirements
Registering in advance requires a NetEase account. Once the test is live you can log in without a participation code, with slots granted first come, first served until capacity is reached.
In other words, this is not a lottery where you wait to hear whether your code came through. It is a race to get in before the slots fill. With five platforms now eligible, assume those slots go fast. At minimum, have the account ready before preloading starts on December 1.
The lack of persistent data cuts the other way too: it means you can mess around without consequence. Forget about a save file you will carry into the finished game and go hunting for broken combinations by pushing builds to extremes. That is the correct way to play a beta.
What kind of game is Sea of Remnants?
It is a turn-based roguelike adventure in which you play a doll-like voyager stripped of their memories, traveling from island to island. Development is handled by Joker Studio, the team behind Identity V.
A story concept trailer titled Embers has also been released. The setting: the fall of the king has collapsed the old pact, leaving factions such as the pirates and the navy to pursue their own agendas.
| Element | Details |
|---|---|
| Developer | Joker Studio (Identity V) |
| Genre | Turn-based roguelike adventure |
| Protagonist | A doll voyager who has lost their memories |
| Setting | A voyage across a chain of islands |
| Trailer | Story concept trailer, Embers |
| Factions | The king’s fall breaks the pact, setting pirates, the navy and others in motion |
The pairing is the interesting part: the Identity V studio making a single-player roguelike instead of another asymmetrical PvP game. What that team does well is character presence and a certain humidity in its worldbuilding. A structure built on sailing between islands suits stacking up small stories, one island per chapter.
My concern is how deep the turn-based roguelike bench already is. The genre is stacked with highly polished work, and comparisons come down to how good the card and artifact draws feel. Strong worldbuilding alone will not carry it here, so the question is how much of that layer a two-week test can show off.
One note on sourcing: 4Gamer’s article, published on November 9, was revised at 8:30 p.m. on November 10 at NetEase’s request. The dates and platforms above are based on the corrected version.

Sea of Remnants CBT details, summarized
The closed beta test, the Dawnbreaker Test, runs from Friday, December 4 to Friday, December 18, 2026. Preloading opens on Tuesday, December 1, and the supported platforms are PC (Windows), PS5, Xbox Series X, iOS and Android. Japanese is supported in both text and voice.
Registering in advance requires a NetEase account, and once the test is live you can log in without a participation code (first come, first served up to capacity). Play data is deleted when the test ends, and nothing carries over to the full release. Development is by Identity V studio Joker Studio.
The previous alpha was locked to PC; this one opens up to PS5 and phones. That alone moves the CBT up a rung, because it means verification is now happening on the assumption of a multiplatform launch. And since entry is capacity-based rather than a code lottery, get that NetEase account created before December 1.
Two weeks, with nothing carried over. Which is exactly why this is a test where going looking for broken builds is fair game.
