LINE Games has officially opened the call for participants for an upcoming Steam Playtest of its self-developed new PC title, 'QUIET'. The recruitment begins on July 21st via the Steam store page, where interested users can apply by clicking the request access button.

The Steam Playtest for QUIET is scheduled to begin on August 3rd, featuring the game's first stage. Additionally, the developer will showcase a co-op mode, allowing players to team up and experience the fun of overcoming crises together.

QUIET is a co-op comedy horror game where players take on the role of an alien duck that has crash-landed on Earth, attempting to escape the watchful gaze of a boss grandmother. It supports both solo play and co-op for up to four players, characterized by a unique atmosphere created by the contrast between the adorable alien duck and the terrifying grandmother.

The title first garnered attention in April for its bizarre atmosphere, followed by its first public demo at PlayX4 2026 this past May. LINE Games aims to use the feedback gathered from this test to polish the game, with a goal of a full global release within this year.
