Key Highlights:
- LINE Games says QUIET attracted more than 30,000 Steam playtest participants within three days.
- The 1–4 player co-op horror game makes movement, object interactions and microphone noise part of its stealth system.
- Players control alien ducks searching a hostile grandmother’s house for the parts needed to repair their crashed spacecraft.
LINE Games says its upcoming co-op horror game QUIET passed 30,000 Steam playtest participants within three days of opening its first public test.
The Steam playtest began on August 3, 2026, after LINE Games opened registrations in July. Earlier English-language coverage focused on the test itself, making the 30,000-player milestone the first measurable indication of how much interest the unusual horror concept has generated.
QUIET is a 1–4 player online co-op game developed and published by LINE Games Corporation. Players take control of alien ducks whose spacecraft has crash-landed on Earth. The missing ship components are inside a nearby house, forcing the group to search its rooms while avoiding the homeowner.
The threat is an elderly woman who reacts to the amount of noise the group creates.
Movement generates noise. Interacting carelessly with objects can generate more. Voice communication can also become dangerous because QUIET requires a microphone and incorporates real-world sound into its detection system. Steam describes talking, movement and panic as potential risks when the homeowner is listening.
That means voice chat is not simply a communication tool. Players need to coordinate while simultaneously controlling how loudly they speak, creating a direct conflict between teamwork and stealth.
I think that mechanic is the real reason the 30,000-player figure matters. QUIET is not relying only on the familiar four-player horror formula. It gives normal multiplayer communication a mechanical consequence, which is exactly the kind of simple rule that can create unpredictable moments between friends.
The current playtest exposes the game’s first publicly available stage and includes its co-op mode. LINE Games originally described the test as the first opportunity for players to experience QUIET outside internal development.
The Steam version also reveals several details that were less clear when the playtest was first announced. QUIET currently targets a full PC release sometime in 2026, requires 4GB of storage and supports 11 interface languages, including English, Japanese, Korean, Simplified Chinese and Traditional Chinese.
| QUIET detail | Confirmed information |
|---|---|
| Players | 1–4 online |
| Developer | LINE Games Corporation |
| Platform | PC via Steam |
| Release window | 2026 |
| Microphone | Required |
| Storage | 4GB |
| Core objective | Recover crashed ship parts |
| Main threat | Noise-sensitive homeowner |
The game also supports solo play, despite being primarily presented as a co-op experience. Steam currently lists both single-player and online co-op functionality, although LINE Games has placed most of its marketing emphasis on groups working together.
Its premise places QUIET within the growing wave of co-operative horror games built around social chaos, but the microphone mechanic gives it a different source of tension. Instead of treating player chatter as something outside the game, QUIET turns it into information the enemy can react to.
The system also appears broader than microphone detection alone. LINE Games says accumulated noise from movement and interactions increases the homeowner’s aggression, meaning a team can make the situation progressively more dangerous even without somebody shouting into a headset.
That creates a useful risk structure. Players need to search rooms and physically manipulate the environment to make progress, but those same actions can increase the threat pursuing them.
The playtest milestone does not represent concurrent players or sales. It refers to cumulative participants in the Steam test, so the figure should not be compared directly with Steam concurrent-player records.
Even with that distinction, reaching more than 30,000 participants in three days gives LINE Games a substantial early testing pool before QUIET’s planned 2026 launch.
The game currently has no final release date. Its Steam page remains listed for 2026, and LINE Games has not announced versions for PlayStation, Xbox or Nintendo Switch 2.
