Patch Notes & Updates FAQ
When does In Falsus release?
In Falsus released on September 9, 2026, on Steam (PC), announced via the official Twitter account. A free demo had been available since February 2026 and was removed from the store at launch.
Is In Falsus free?
The full game costs $39.99 USD — ¥166 in China, ¥4,980 in Japan, €39.99 in the EU and £34.99 in the UK — with a 10% launch discount until September 23, 2026. The free demo was removed from Steam at launch.
What platforms is In Falsus on?
PC only, via Steam (Windows). No mobile, Switch or console versions have been announced — despite lowiro being known for the mobile game Arcaea.
How do I update In Falsus?
You don't have to do anything: Steam downloads new versions in the background and applies them the next time you launch the game. There is no in-game updater or manual patch to install, and the build number isn't shown in-game — the Steam news hub post for each patch is the reliable way to see what you're playing. (The demo, removed at launch, updated the same way; its final build was v0.3.1.)
Where are official In Falsus patch notes published?
On the game's Steam news hub (store.steampowered.com/news/app/3971950) and on the official X accounts @infalsus_en and @infalsus_jp — the launch announcement and the v1.0.3, v1.0.4, v1.0.5 and v1.0.6 patch notes were all posted there. Not every build gets its own post: silent hotfixes still reach Steam, but ship without a changelog.
What's in the latest In Falsus patch?
v1.0.6 (October 7, 2026) is the latest announced version — a quality-of-life patch with no new songs: the Clear/EX song counter displays its count, DLC songs show difficulty levels before purchase, certain boss encounters allow retrying, and fixes cover Scenario text, Crafting and Song Select UI, large Iota inventories and note flickering at specific track speeds. The previous patch, v1.0.5 (September 30, 2026), shipped the Virtual Singers Song Pack DLC.
Does In Falsus support Steam Cloud and auto-updates?
Yes. Steam Cloud is listed among the game's official Steam features, so your save data syncs through your Steam account. Automatic updates are the Steam default and In Falsus is no exception — patches download in the background and apply on the next launch.
Is there any DLC or Season Pass for In Falsus?
Yes — one. The Virtual Singers Song Pack, In Falsus's first paid DLC, launched September 30, 2026 alongside v1.0.5: five Vocaloid tracks (Monitoring, Non-breath oblige, Roki, Lost One's Weeping, Apparently there's a cheat code to happiness) sold as a single pack, playable with no scenario progression. No Season Pass has been announced — everything else since launch has been a free update.
Is there a mobile, iOS, or Android version of In Falsus?
No. In Falsus is Steam/PC exclusive — Windows only, with no official iOS, Android, or iPadOS release announced. Despite lowiro making the mobile game Arcaea, In Falsus is built for keyboard-and-mouse desktop play. Unofficial APK or IPA downloads on third-party sites are not authorized by lowiro; they may contain malware, outdated builds, or stolen assets. The only legitimate way to buy and play In Falsus is through Steam (store.steampowered.com/app/3971950).
Why does the audio desync from the chart in In Falsus?
Some players report charts occasionally drifting out of sync with the music — several note they didn't experience it in the demo. v1.0.4 changed the default audio buffer size selection, which targets exactly this area; if you still see drift, calibrate the in-game Audio Offset and check your system sample rate. Our audio desync fix guide walks through both step by step.
