Duet Night Abyss is an upcoming 2025 action role-playing game developed and published by Hero Games. The game is scheduled for release on 28 October 2025, across Microsoft Windows, Android, and iOS. The game supports switching between melee and ranged combat while employing a dual-protagonist narrative structure.
The game is set on Atlasia, a continent where magic and machinery coexist. Players experience the story through two protagonists from different social backgrounds, interacting with rival factions and engaging in exploration and combat within an open-world framework.
In 2025, the game held two closed tests, and on 26 August the developer announced the removal of character and weapon gacha and the stamina system, shifting monetization toward cosmetic purchases and confirming the global launch date.
The game is an action role-playing game featuring open-world elements, [a] allowing players to control multiple characters and experience the story from different perspectives. Throughout gameplay, each character can equip melee and ranged weapons, swiftly switching between close-quarters and long-range attacks during combat. Additionally, players can select two characters as AI companions to assist in battle. [5]
The player can control their character and perform basic movements like jumping, and a traversal move called "Helix Leap" enables rapid movement across distances. [5] [6]
The game initially considered using a gacha system for acquiring characters and equipment, but later switched to a system where players obtain items through free gameplay to acquire characters and gear. [7] The star ratings for characters and weapons are also expected to be removed. [5]
