Following months of playtesting and growing excitement since its initial announcement in late 2023, Duet Night Abyss is finally approaching its most significant milestone yet. The Final Closed Beta Test commences next month, bringing players one step closer to the official launch of Pan Studio's thrilling fantasy action RPG.
With over three million pre-registrations already recorded, it's evident that a substantial audience eagerly awaits Duet Night Abyss's release. That's precisely why you won't want to miss this upcoming test phase—it offers the most polished gameplay experience to date and represents your final opportunity to dive in before the game officially launches.
Scheduled to run from June 12th to July 2nd, the Final CBT will grant a limited number of players early access to a brand-new chapter named Children From the Snowfield. This updated build includes expanded main story and side quests, introduces additional characters, and features comprehensive visual enhancements.

Duo Truffle and Filbert will return to center stage with all-new narrative sequences, deeper backstory revelations, and dynamic combat mechanics—all showcased in the latest trailer. The video also highlights the voice actors behind these charismatic characters: Lizzie Waterworth-Santo (known for Arknights and CITV) provides the English voice performance, while Aki Toyosaki (recognized from Persona 5, Sword Art Online, and Genshin Impact) leads the Japanese voice cast.
