Publisher Hero Games and developer PAN STUDIO have announced that the second and final closed beta test for their free-to-play fantasy adventure RPG Duet Night Abyss will take place from June 12 to July 2 across PC, iOS, and Android platforms. Player recruitment for the closed beta began on May 12 and will conclude on June 2. Interested participants can register through the game’s official website or enter the lucky draw event for an opportunity to join the testing phase.

The upcoming beta introduces a new chapter titled “Children From the Snowfield,” which expands the game’s narrative with enhanced main and side storylines, additional playable characters, and improved visual performance. The test will feature returning characters Truffle and Filbert, who gained significant attention during previous testing phases for their distinctive combat mechanics.

Voice acting for these characters includes English voice actor Lizzie Waterworth-Santo, known for her work in Arknights and CITV, alongside Japanese voice actor Aki Toyosaki, who has provided voices for characters in Persona 5, Demon Slayer: Kimetsu no Yaiba, Sword Art Online, and Genshin Impact.

Duet Night Abyss has achieved over three million global pre-registrations, prompting the developers to offer exclusive milestone rewards that will be available to all players once specific goals are reached. The game also features an ongoing official content creator event, encouraging fans to submit artwork, videos, memes, and other creative content through the official event portal for chances to gain test access and additional rewards.
