What is Duet Night Abyss?
Duet Night Abyss is set on Atlasia, a continent where magic and machinery coexist, with players experiencing the story through two protagonists from different social backgrounds. The game employs a dual-protagonist narrative structure supporting switching between melee and ranged combat.
The game completely removed gacha mechanics and stamina systems, transforming it into a normal game where all characters and weapons can be earned directly through gameplay. Resources are primarily obtained as rewards from “Covert Commissions” which consume “Secret Letters” to initiate. Players engage with rival factions, explore open-world environments, and participate in cooperative multiplayer missions supporting up to four players.
How long is Duet Night Abyss?
Because Duet Night Abyss offers varied content types from story progression to character farming and endgame challenges, total playtime differs based on goals and playstyle:
Main Story (Prologue & Early Chapters): ~3–6 hours
Tutorial and initial gameplay take around 3 hours; unlocking the Friends mechanic is an early milestone.
Story + Character Unlocks: ~15–25 hours
Completing main and side quests, earning launch rewards, and unlocking multiple characters takes 15–25 hours.
Full Character Collection & Endgame: 40+ hours
Solo roguelike “Mystic Abyss,” Covert Commissions, farming Thoughts, and mastering endgame content require significant time.
Daily Activities & Long-Term Play: Ongoing
