“In Falsus” by lowiro — A Rhythm Game Embedding a Complete Visual Novel Now Available on Steam
Rhythm game junkies all over the world rejoiced when on 9 September 2026, British video game publisher lowiro finally released their newest rhythm game project In Falsus onto Steam. The game supports Japanese, English and Simplified/Traditional Chinese language options. While In Falsus is the successor to their exclusively mobile rhythm game hit Arcaea, it is their first game strictly designed for PC. The game can be purchased on Steam for ~$40 with a current discount of 10%.
About In Falsus
In Falsus is lowiro’s newest standalone video game that bridges many genres into one slick package: the rhythm game portion is a highly demanding one-handed 6-Key + mouse flick motion rhythm game with a high skill ceiling to master, and the storyline is told as a full-length visual novel, which features crafting and card builder mechanics to enhance scoring, visual effects and modifiers to other aspects of the gameplay. While the full game contains around 70 songs (40 of them originals) with each having 4 difficulties included, it’s highly likely the game will be expanded with plenty of DLC in the coming months — the same way it’s handled for the original Arcaea, boasting 549 songs since its inception.
Originally, In Falsus was announced on 25 September 2025 with first time open-access to their Discord server on 6 February 2026. Around the same time, a demo had been available since 11 February 2026. However, as the demo WAS available for the longest time, it has been delisted upon release of the full game and is inaccessible now.
The demo had featured five playable songs (only listed here to give an impression)
Later in the year in April the demo had been updated with a new unlockable song and first impressions of the card integration system.
Then on 22 July 2026 they announced the determined release date for In Falsus: 9 September 2026, which was their last update until the release. Now post-release, there has also been an added letter by executive director and lowiro CEO Guy-kun addressed towards the community and all supporters.
