There is no official release date for Duet Night Abyss Version 1.1 at this time. The game launched globally on October 28, 2025 (UTC+8), and the studio has not published a schedule for the first major update. Expect the date to remain unconfirmed until the developer posts a formal timeline.
What the launch tells us about the 1.1 window
With the global release now live, the cadence for early post-launch content is starting to take shape. A post-launch character, Fina, is expected to land on November 25, positioning her as the bridge between launch content and the first big update. Following that, Version 1.1 is expected to introduce the Huaxu realm alongside a new wave of characters. Until the studio shares a date, treat this as the current near-term plan rather than a locked calendar.
Expected 1.1 roster and near‑term additions
Here’s the current picture of who to expect next. Names and windows reflect the present plan, which can shift as the patch is finalized.
| Character | Window | Notes |
|---|---|---|
| Fina | Nov 25 (post‑launch) | Support with debuffs and notable damage potential; obtainable through regular in‑game systems |
| Zhiliu | Version 1.1 | Part of the first major update lineup |
| Fushu | Version 1.1 | Teased; no specific date yet |
| Yuming | Version 1.1 | Teased; no specific date yet |
| Kezhou | Version 1.1 | Part of the first major update lineup |
| Hilda | After 1.1 | Planned for a later patch |
Why the no‑gacha model changes how you plan for 1.1
Duet Night Abyss launched with three pillars: all characters and weapons are free to unlock, there’s no stamina system gating play sessions, and monetization focuses on cosmetics. That has practical effects on how you prepare for 1.1:
- No fear of missing pulls. You can wait to see how 1.1 kits perform before committing scarce materials.
- Steady roster growth. Characters arrive through play, events, and shops rather than limited‑time banners.
- Time, not currency, is the constraint. With no stamina cap, you can run the modes you need when you need them.
What to do now while waiting for 1.1
You don’t need a date in hand to make progress that carries into the first big patch. Focus on foundational unlocks and a stable core team.
- Push the main story to unlock your hub, Sanctuary, and core modes.
- Secure early free characters through story progression and tutorials. Build a balanced trio to clear launch content comfortably.
- Pick a single carry and level them to a solid breakpoint before spreading resources thin.
- Run Covert Commissions regularly to target character thoughts, weapon unlocks, and key materials in the background.
