In Falsus is a rhythm game that blends demanding note charts with a visual novel narrative on PC. Developed by lowiro, the studio behind Arcaea, it places players in a near-future setting where five high school girls navigate a world shaped by visible emotions and enforced honesty through mysterious collars known as Binds. The CHUNITHM Collaboration Song Pack expands the soundtrack with five new tracks drawn from the arcade rhythm game CHUNITHM, allowing direct access to the added songs without advancing the main scenario.
Gameplay
Core play centers on a hybrid control scheme that splits input between keyboard and mouse. The left hand manages six buttons on the keyboard for standard note streams, while the right hand directs the mouse to handle flick notes and extended laser notes that travel across an aerial field. Charts scale across four difficulty tiers that increase note density and field movement. A separate card crafting system lets players combine materials earned from play into custom cards that influence encounters. These cards introduce light strategic layering without altering the fundamental rhythm focus. Story scenes advance through visual novel segments voiced in Japanese, with rhythm sections triggered at key narrative points called encounters.
Game Modes
The primary structure combines a continuous scenario that follows the five protagonists through interconnected events with standalone rhythm play. Scenario progression unlocks additional songs and content through story encounters, though the collaboration pack songs remain playable independently. Rhythm sections function as direct challenges tied to specific tracks, emphasizing accuracy and timing across the full range of difficulties. No separate multiplayer or competitive modes exist; all activity stays single-player focused on personal mastery of charts and narrative exploration.
Soundtrack Expansion
The base game launches with more than seventy tracks, over forty of them original compositions spanning electronic and other styles from Japanese independent and international artists. The CHUNITHM Collaboration Song Pack adds five specific additions: Disruptor Array by Akira Complex vs kiraku, Megameteor by 削除, TECHNOPOLIS 2085 by PRASTIK DANCEFLOOR, Yume no hajimari by Virtual Cat, and Space Creation Theory by Sound piercer. These tracks integrate into the existing library and support the same control and difficulty options as core content.
Is It Worth Playing?
Players seeking precise, high-skill rhythm gameplay with an inventive keyboard-and-mouse layout will find strong appeal in the chart design and visual presentation. The narrative component appeals to those interested in character-driven stories about truth and deception, though it gates some song access behind scenario progress. Recent updates continue to add content through collaboration packs like the CHUNITHM set, maintaining ongoing support after the September 2026 launch. The experience suits dedicated rhythm fans comfortable with a steep initial learning curve and those willing to engage the full package of music, cards, and story rather than isolated tracks alone.
