## What is Duet Night Abyss?

Duet Night Abyss is a fantasy adventure RPG with a high degree of freedom developed by Hero Games' Pan Studio. The game features "Multiple Weapon Loadouts x 3D Combat" at its core, and tells the story of "Demons" from dual perspectives. 

[All Characters & Weapons Free to Unlock — Craft your own lineup]
Freely farm character fragments and forging materials to unlock your favorite characters and weapons at your own pace. No forced progression, no rigid templates—just the joy of free cultivation and strategic experimentation. Focus on strengthening your core squad or exploring endless tactical possibilities.

[Destinies intertwine — Meet demons of a hundred faces in the DNA]
You will step into a land where magic and machinery coexist, playing as two protagonists with vastly different backgrounds. Encounter a variety of demonic beings with their own perspectives as you engage in constant battles and exploration to uncover the truth behind a thorny fate, ultimately bringing an end to the spiral of suffering.

[Swap between melee & ranged weapons — Freely create multi‑dimensional weapon combos]
In battles, you can freely switch between melee and ranged weapons, allowing characters to break free from the limitations of a single weapon class. Choose from a variety of cool melee weapons such as whipblades, crossbows, and even heavy firepower like sniper rifles, grenade launchers, and high-tech hover guns to create your unique weapon loadouts.

[Exhilarating hack‑and‑slash battles — Master agile moves and mow down hordes]
Engage in fast-paced combat against waves of relentless enemies with the freedom to utilize both close and long-range attacks, as well as aerial assaults and ground takedowns. Bask in unexpected and thrilling battle experiences through diverse combat gameplay including tracking, reconnaissance, and rescue missions.

[Customize your look with dyes — Mix & match—colour weapons & outfits freely]
Dye and switch at will—take full control of your weapon and character aesthetics. Swap color schemes on the fly to match your combat style with your personal flair. Combine a wealth of accessories—from elegant headpieces to lively waist ornaments—whether for refined beauty or playful fun, the choice is yours.

================================
In the long and repetitive dream, 
Quicksand constantly pours down.
The compass of destiny starts to tick. 
The two wake up and embark on their separate journeys.

On this shore, you emerged from a perilous situation but were exiled to the harsh North Border, struggling to survive.
On the other shore, you found yourself in a maelstrom of power, striving to escape from a cage woven with conspiracies.

No need to bid farewell.
As time perpetually flows forward, 
As the two shores will eventually meet,
You will meet each other one day.

### 3/5 — Everything’s great but ONE

*2026-08-24, version 1.5.0*

Could you please optimize the game to make it compatible with any controllers? Everything works fine until I connect my PS5 controller

### 5/5 — Good game, but a lot of bugs.

*2026-08-15, version 1.5.0*

This game is really nice and I got it not that long ago, but the problem I’m having that’s real annoying is logging out. Idk if this happened to other players but the game logs me out after about 5 minutes and I can’t even hardly enjoy the game because of it. So please fix this. I want to enjoy the game. It’s also very laggy too, but idk if that’s because I play on iPad. I don’t want to delete the game then redownload it because something similar like this happened to another on of my games and deleting the game and getting again made me getting kicked out of the game worse. So I'm not sure what else to do. But please, please fix this!. I really want to enjoy this game.

### 1/5 — Управление

*2026-08-10*

iPhone 14 Pro Max. Управление персонажем полный шлак. Не смог забраться на 2й этаж двойными прыжками. Кнопка прыжка, как будто в блокировку уходит. Ставлю кол за такое

### 1/5 — Horrible mobile controls, clunky and unresponsive

*2026-08-07, version 1.5.0*

Title says it all. It such a major headache to even try and play this game on a mobile device.

### 3/5 — Great potential but some obstacles

*2026-08-06, version 1.5.0*

Character designs are really nice, but the controls on mobile are horrible. They lack the convenience of other similar genre games. It's difficult to move forward in a straight line or to turn the screen while moving.

### 1/5 — Love the game, will never run

*2026-07-28, version 1.5.0*

I have tried and tried to get into the game off and on for the months it has been online. It is no where close to optimized for mobile and in my eyes if you are going to make a game available for mobile your mobile optimization should be the priority. You have such a severe data leak or what ever is going on that it is absolutely refusing to run the game on any graphical setting that is attempted. So basically, constant crashes even with the latest of funs and everything else shut off but the game. Suggestion is remove it for mobile in its entirety and fully lean into PC and make it a real video game instead of half assed, mobile is holding you back.

### 1/5 — This

*2026-07-07, version 1.4.0*

This game is genuinely so boring which is sad because of how pretty some of the designs are and if feels damn near impossible to get characters

### 1/5 — Can’t even login

*2026-06-30, version 1.4.0*

You give me the option to login with google on pc but don’t on mobile. Really?🫩

### 4/5 — Give it another chance

*2026-06-26, version 1.4.0*

The game does have problems but they are fixable and the Devs seem motivated. I gave the game a chance and I’m really enjoying myself.

### 3/5 — Walking

*2026-06-21, version 1.4.0*

I wish there was a way to remove the walking button.
