The game combines a rhythm game with a visual novel format, featuring a control scheme that uses both keyboard and mouse simultaneously. Players press up to six keys (Shift, A, S, D, F, Space) for bottom-lane notes while moving the mouse to catch floating notes on the upper lane. The story follows five high school girls in a near-future world where emotions are exposed and lies are forbidden, each with her own route that players can freely choose. The game includes over 70 songs, more than 40 of which are original compositions written for In Falsus. A music video for the new song 'Empty Shell' by Camellia feat. Nano was released alongside the announcement. A demo version is currently available on Steam. To commemorate the release, a lottery campaign for autographed signboards from the five main voice actors will be held on the official X account, with details announced on July 23. The voice cast includes Fuka Izumi, Ran Haruka, Kanon Amaki, Ayame Fujiue, and Miri Saito.","whyItMatters":"In Falsus marks lowiro's first PC-native rhythm game and a deliberate departure from Arcaea's touch-based mobile design, betting that a keyboard-and-mouse control scheme can attract a different audience while retaining the studio's story-driven approach.","webCardHtml":"\u003cp\u003eLowiro was founded in 2016 and is an international indie team with members from around the world, according to the press release. The studio\u0026#39;s first title, \u003cem\u003eArcaea\u003c/em\u003e, launched in 2017 as a live-service rhythm game and is celebrating its ninth anniversary this year.\u003c/p\u003e\n\u003cp\u003eThe game is built on three pillars: the keyboard-and-mouse control scheme, a long-form ADV scenario with full Japanese voice acting, and card crafting elements. Players can equip up to five cards before a song, each offering different effects. Cards are formed by combining materials obtained through gameplay, and a \u0026#34;blueprint\u0026#34; system allows players to create cards with arbitrary stat boosts, functioning as a puzzle mechanic. Card illustrations are drawn by various illustrators in different styles.\u003c/p\u003e\n\u003cp\u003eThe rhythm game section has four difficulty levels. Lower difficulties use only four keys instead of six. The upper-lane notes caught with the mouse include some that require flicks. The game\u0026#39;s sound design is directly connected to in-game events, forming an integrated story experience.\u003c/p\u003e\n\u003cp\u003eThe story follows five high school girls who become involved in a mysterious government-directed program. Each character has her own route, and the routes are closely intertwined. Full Japanese voice acting is used throughout the scenario.\u003c/p\u003e\n\u003cp\u003eThe game supports Japanese, English, and Chinese languages. The official website is infalsus.lowiro.com. The official X accounts are @infalsus_en (English) and @infalsus_jp (Japanese). The studio also has a TikTok and Instagram account under the handle @infalsus.\u003c/p\u003e","blueskyPost":"In Falsus, the new rhythm game from Arcaea developer lowiro, launches September 9 on Steam.
