Short answer: no. The launch version of Duet Night Abyss removes character and weapon gacha entirely. There’s no stamina system either. All playable characters and weapons are obtainable in-game through regular play, and the business model is cosmetic-only.

What Duet Night Abyss is (platforms and basics)

Duet Night Abyss is a free-to-play 3D action RPG from Pan Studio (Hero Games) built around fast, third-person combat and flexible loadouts. It’s available on PC via the official Steam listing at Duet Night Abyss on Steam, with mobile versions on iOS and Android. The game emphasizes “Multiple Weapon Loadouts x 3D” combat and a high degree of freedom in how you approach encounters.

Release timing for the global version is set for October 28, 2025.

How progression works without gacha

With gacha removed, progression shifts to straightforward play-and-earn systems:

  • Characters: Unlocked by playing. You don’t need pulls, currency, or pity systems to add new fighters to your roster.
  • Weapons: Earned in-game and usable across characters, so you can build loadouts without chasing banner-specific drops.
  • No stamina: Dungeons and repeatable content aren’t time-gated by an energy bar, so you can farm materials at your own pace.

New characters are planned as permanent additions rather than time-limited banner exclusives. The result is a progression model you can chart and complete through gameplay alone.

What you can buy: cosmetic-only monetization

Spending is limited to optional cosmetics. Expect items like skins, special animations, and accessories that don’t alter combat stats or gate content. There are no paid power boosts to keep up with, and no banner cycles pressuring you to spend on limited units.

Practical upside: you can focus builds around the weapons and characters you enjoy without budgeting for pulls or passes. If you choose to pay, it’s for aesthetics.

Then vs. now: what changed at launch

System Earlier test versions Launch version
Character acquisition Gacha banners with “can’t-miss first pull” style mitigation Direct unlocks via gameplay; no gacha
Weapon acquisition Mix of in-game methods and gacha; “Secret Letter” routes tested In-game unlocks; no weapon gacha
Energy/stamina Stamina (often referred to as Sanergy) No stamina system
Monetization Hybrid (gacha + cosmetics) Cosmetics only

What this means if you’re deciding to play

  • No gambling loops: There’s no currency juggling for pulls, no pity math, and no fear of missing a limited meta unit.
  • Time is the investment: Progress hinges on playtime and mastery, not microtransactions. Without stamina, farming sessions are on your schedule.
  • Build freedom: Any character can use any weapon, so experimenting with loadouts doesn’t require chasing specific drops.

Where to get it

On PC, grab the game from the official Steam page. It’s also available on iOS and Android as a free download.

The key takeaway: Duet Night Abyss positions itself as an action RPG first, with a clear, non-gacha path to every character and weapon, and a business model that stays cosmetic by design.
