About In Falsus

In Falsus Hyaloüyne chart showing Floor keys, EXACT judgements, and the aerial Field

In Falsus is lowiro's PC rhythm game with a visual-novel Scenario: five high-school girls, collars that expose emotion and deceit, and songs that lock to story Encounters. Read the getting started guide for the demo loop, then the controls page before you touch ULT charts. Card crafting lives in the Iota integration guide, while character profiles and the song difficulty hub help you pick a first route and a first chart.

Quick start

A practical path from wishlist to your first MIN clear.

  1. 1

    Wishlist and install the demo

    Open the Steam page, wishlist In Falsus, and download the free demo. The Steam demo walkthrough lists every playable song and Scenario slice currently on the store.

  2. 2

    Learn Floor keys and the Field

    Default binds are Left Shift, A, S, D, F, and Space plus mouse motion. The mouse-keyboard controls guide explains MIN's four-key subset, flicks, and why one-handed six-key layouts feel brutal at first.

  3. 3

    Stay on MIN until timing clicks

    Each song has MIN, EVO, ULT, and locked FBD charts. Use the difficulty guide, beginner song picks, and the known song list so you do not jump to ULT after one clear.

  4. 4

    Craft Iota into Cards

    Demo version 0.3.0 previews Card Integration: earn Iota, fill Blueprint grids, equip up to five Cards. The Iota card guide covers why card score sits beside accuracy score.

  5. 5

    Pick a first protagonist

    Nia, Mei, Ayame, Iris, and Story Étienne can be played as separate routes that braid together. Start with the character hub and the spoiler-light Scenario guide.

FAQ

Wiki FAQ

Quick answers for demo players and launch-week questions.

When does In Falsus launch?

lowiro set a worldwide Steam date of September 9, 2026. Details live on the release date page. The full game is not out yet; treat launch-week claims on social media as unofficial until Steam unlocks.

Is there a demo?

Yes. The Steam demo shipped on February 11, 2026, received 0.2.1 stability fixes on February 13, and expanded on April 22, 2026 with extra Scenario scenes, a sixth song, and a Card Integration preview. Follow the demo walkthrough and demo changelog.

How do you play the rhythm parts?

One hand hits Floor notes on the keyboard while the other steers an aerial Field with the mouse, including left and right flicks. Read controls and scoring before grinding ULT.

Which languages does the game support?

Steam lists English, Japanese, Simplified Chinese, and Traditional Chinese for interface and subtitles. Full voice acting is Japanese. This wiki is English, Japanese, and Traditional Chinese.

Is In Falsus multiplayer or a Roblox game?

Neither. It is a single-player PC title from lowiro, the studio behind Arcaea. There is no multiplayer, and it is not on Roblox. See system requirements for the Steam Deck note.

Where should a new player start on this wiki?

Open getting started, then controls, then a character page. Use tools if your keyboard layout or PC spec is the blocker, and settings if the client itself misbehaves.

Will In Falsus be playable at Tokyo Game Show 2026?

Yes. lowiro is in Hall 3 C-01 from September 17–21, after the September 9 Steam date. Booth notes live on the TGS 2026 page.

Ready for September 9?

Wishlist the game, clear the demo on MIN, then use the controls guide and Iota card guide so launch week is about story — not fighting the keyboard.
