In Falsus Updates
Dated facts from lowiro and Steam, not rumor-blog launch countdowns.
This hub is the timeline. In Falsus is an upcoming Steam release, not a title that already shipped. The date on the store is September 9, 2026. Until Steam unlocks the full client, every “full game review” you see is a demo impression wearing a louder hat.

What this hub will not do
We will not list gift codes. This is not a live-service Roblox title. We will not mark the game as “out now” before Steam does. We will not invent a price. We will not pretend Steam Deck Native when the store says Playable.
When launch-day patches land, they will be dated here and in the changelog page. Until then, the demo walkthrough is the playable news.
Where to verify a rumor
- Steam news hub for app 3971950.
- Official site infalsus.lowiro.com.
- @infalsus_en and the Japanese counterpart.
- This wiki’s links page.
If a Discord screenshot disagrees with those four, it is not a patch note.

News is useless if you do not play the demo. After you read the date page, go to getting started. After you read the changelog, go to card integration because that is what 0.3.0 actually added.
