Duet Night Abyss issues apology for issues at game launch, announces upcoming optimizations

The launch of Duet Night Abyss was received with both praise, because of its fun gameplay aspect, and criticism for its weird performance issues. PAN Studio has published a statement, acknowledging the underbaked aspects of the game and promising to fix the issues in the future. The developers have also issued compensation as rewards.

Let's take a look at everything that the developers announced for Duet Night Abyss.

All upcoming optimization changes and updates in Duet Night Abyss

Performance updates

The developers announced that the mobile version will undergo several optimization updates to enhance the visuals. The following changes were listed in the announcement:

• Improve dynamic resolution, specifically enhancing clarity in the Armoury interface via online update.
• Enlarge UI text that is currently too small on mobile.
• Adjust Helix Jump on mobile by adding an optional Helix Jump button.
• Enhance anti-aliasing and rendering resolution for better graphics.
• Optimize the Icelake scene to reduce lag.
• Improve character lighting, texture precision, and material quality.
• Upgrade scene lighting and material rendering, and add texture types.

These are planned for the next launcher update, which is set to be released in late November. As announced, the developers are also looking into and actively trying to solve the ongoing Duet Night Abyss errors.

Character acquisition details

The developers of Duet Night Abyss also announced the following details regarding how to obtain characters in the game.

• When Psyche is released, you can obtain her Secret Letter through the Immersive Theatre.
• When Fina is released, she will replace Psyche in the Immersive Theatre, while Secret Letter: Psyche moves to Nocturnal Echoes. One existing character's Secret Letter in Nocturnal Echoes will then move to the exchange shop.
• As more characters join, Secret Letter: Psyche will eventually move to the exchange shop after about 3.5 versions. Before that, it remains available in Nocturnal Echoes. The same applies to weapons first available in Immersive Theatre. The specific schedules will be updated through future announcements.
• Each version will add Secret Letters for one melee and one ranged weapon to the exchange shop, purchasable without limit using Secret Letter Clues.
• Besides fixed rewards, Secret Letter Clues now have a chance to drop from enemies in all commission gameplay, with rates increasing alongside your Trial Rank. Drop info has already been added in-game.

One key change that the developers announced is that now you can obtain Secret Letter Clues from all the enemies in the Commission Stages. The better your Trial Rank in DNA is, the rate will also increase.

Other updates

• Server "Looping" Issues: Shortly after launch, some servers experienced recurring "looping" and lag. A fix was deployed on the evening of Oct 28, and the devs will continue to monitor network stability.
• Delayed Purchases: Some users reported not receiving purchased items promptly. We've issued missing items via the backend. If you still haven't received yours, please contact customer service.
• Controller Support Improvements: Some controller recognition and input issues are known. The devs have planned fixes in upcoming versions and are developing mobile controller adaptation.
• Crashes & Progression Blocks: The developers addressed the reports concerning crashes, update failures, stuck quests, co-op lag, and missing guides. Some issues have been fixed (please refer to in-game patch notes); others are still being traced and will be resolved gradually.
