LINE Games

LINE Games is running a Steam playtest for its co-op comedy horror title QUIET, scheduled for release within 2026, while its manga service Manga Up! Global continues to add new licenses.

Synthesized from 5 Yomimono stories · updated Aug 5

LINE Games' most recent activity centers on QUIET, a cooperative comedy horror game for up to four players. Announced on August 3, 2026, the game casts players as duck-shaped aliens who crash-land on Earth and must sneak into houses to steal parts for their spaceship while avoiding a supervisor. The core mechanic is sound: any noise reveals the player's position, and louder sounds make the supervisor pursue faster. A Steam playtest began the same day, letting players challenge the first stage with teammates. LINE Games plans to improve the game based on participant feedback, and the full release is scheduled for within 2026. The playtest includes three difficulty levels, with Normal as the default, and play data will not carry over to the full version. Controls are currently keyboard and mouse only, with controller support planned for future updates. The game supports Japanese.

Separately, LINE Games' manga platform Manga Up! Global added three new licenses in late June: The Lonely King and His Sunshine Bride's Happily Ever After, Yoshi no Zuikara, and Don't Pry Into People's Genders in Online Games!. The titles were released between June 24 and June 30, covering romance, slice-of-life, and BL comedy genres.

The stories do not connect these two efforts into a single strategy. LINE Games is active in both game development and manga distribution, but the coverage treats them as separate lines of business.

Leafy Corner Launches With 99% Positive Steam Reviews

Fireline Games released the houseplant shop management game Leafy Corner on July 31 for PC (Steam and Microsoft Store), Nintendo Switch, PS5, Xbox Series X|S, and Xbox One. The game has quickly drawn attention, with Steam user reviews at 99% positive out of about 120 reviews at the time of writing, earning a 'Very Positive' rating. SteamDB data shows a peak concurrent player count of roughly 2,100 players so far. In Leafy Corner, players run a shop in a corner of the city, starting from a small, empty space. They purchase tables and shelves, arrange products, and sell houseplants to customers. The game includes over 100 types of houseplants, such as aloe vera, moth orchids, and African violets. Players do not buy plants ready-made; they plant seeds, water them, and watch them grow, with value increasing in stages. Each plant type has an appropriate amount of water, and overwatering causes withering. Customers may buy plants they like or ask for recommendations based on conditions like pet safety. A to-do list sets goals, and completing them earns Leaf Coins to unlock new plants, furniture, and decorations. A 20% off sale is currently underway on Steam and the Nintendo eShop, and a demo version is available on Steam.

LINE Games' Co-op Comedy Horror QUIET Begins Steam Playtest

LINE Games announced on August 3, 2026 that it has started a playtest on Steam for its new PC title QUIET, a cooperative comedy horror game for up to four players. Players take on the role of duck-shaped aliens who crash-land on Earth and must sneak into houses to steal parts needed to repair their spaceship, all while avoiding a supervisor. The game's core mechanic is sound: any noise, such as dropping an object, reveals the player's position, and louder sounds make the supervisor pursue faster and more relentlessly. The playtest lets players challenge the first stage in cooperation with teammates, and LINE Games plans to improve the game's quality based on participant feedback. The full release is scheduled for within 2026, and a play movie showing actual gameplay has also been released. The test includes three difficulty levels: Easy, Normal, and Hard, with Normal as the default. Play data will not carry over to the full version, and controls are currently keyboard and mouse only, though controller support is planned for future updates. The game supports Japanese.

Dystopian Sauce Shop Game 'Future Sauce Dispenser' Announced for PC

Publisher FreeMind and developer Wrong Timeline Games announced 'Future Sauce Dispenser', a sauce shop management game for PC via Steam. Set in 2145, players run a sauce stand where customers bring non-food items-broken phones, bricks, shoes-and the player must choose and pour the right sauce to make them edible. The developer deliberately uses generative AI for visuals, text, and the trailer as a satirical statement on dependence on technology and convenience. Release date is undecided.
