In Falsus Release Date
September 9, 2026, worldwide on Steam — demo already on the store.
lowiro dated In Falsus for September 9, 2026 on PC via Steam. The announcement went through the game’s Steam news hub on July 21, 2026, with matching posts on official 𝕏. This page is the launch briefing: what is locked, what is still missing, and how to spend the days before the unlock without believing a fake pre-order key shop.
The full game is upcoming. The demo is the playable build. Those two sentences must stay in that tense until Steam flips the switch.
Platform
- PC, Windows, 64-bit, Steam.
- Developer and publisher: lowiro.
- Engine listed by community wikis: Unity.
- Features listed on Steam: Single-player, Steam Achievements, Steam Cloud, Family Sharing.
- Steam Deck: Playable, not a Native verification badge. Read system requirements before you plan a handheld main.
- Not on Roblox. Not a mobile client. Not a Switch announcement in any official post we can cite.
Languages
Steam language matrix:
| Language | Interface | Audio | Subtitles |
|---|---|---|---|
| English | Yes | — | Yes |
| Japanese | Yes | Yes | Yes |
| Simplified Chinese | Yes | — | Yes |
| Traditional Chinese | Yes | — | Yes |
Full Japanese voice acting is a launch selling point. This wiki covers English, Japanese, and Traditional Chinese. It does not cover Simplified Chinese or Russian, per site rules, even though the game client includes Simplified Chinese.
Price and editions
Price is not listed in a way we can cite as final. Do not trust a random key store. Wishlist on Steam and wait for the official tag. There is no deluxe-edition breakdown on this page because lowiro has not published one we can quote.
Demo versus launch client
You can download the demo today. You cannot play the 70-plus song launch library today. Demo history lives on the changelog. Launch promises from the store:
- Over 70 songs, over 40 original.
- Four difficulties with a mouse-and-keyboard Field.
- Card Integration with Iota and Blueprints.
- Five interconnected protagonist routes, full JP voice.
If a streamer labels a demo VODcast as a launch review, they are early. Wait for September 9.
TGS 2026
Tokyo Game Show 2026 runs September 17–21 at Makuhari Messe. lowiro is in Hall 3 C-01 with In Falsus and Arcaea, business days the 17th–18th and public days the 19th–21st. That booth is after the dated Steam launch. It is a chance to play on show hardware, not a delay rumor.
Campaigns around the date
The July Steam post mentioned an 𝕏 campaign for autograph boards signed by the five main voice actors. Details were promised on official English and Japanese accounts. Watch those accounts, not a giveaway clone.
Hollow’s official MV dropped with the date: Camellia feat. NANO. Listening is free. The chart waits with the rest of the OST.
What to do this week
- Wishlist.
- Finish the demo on MIN.
- Fix binds with controls.
- Pick a first girl on the character hub.
- Ignore anyone selling “launch keys” in DMs.
When the store flips from “coming” to a buy button, this page will change tense. Until then, upcoming means upcoming.
