It happened: lowiro's In Falsus — the rhythm + cards + adventure hybrid — launched on September 9, 2026. This page started as our pre-launch roundup and is now the day-one fact sheet: the confirmed price, the launch discount, what happened to the demo, and everything the release actually shipped with. No leaks and no speculation — when something is not confirmed, we say so.

Out now: launched September 9, 2026

In Falsus is available now on Steam for PC. The unlock hit at 08:00 UTC on September 9 — exactly the timestamp SteamDB had listed — and lowiro's "In Falsus Out Now on Steam!" announcement confirms the launch the same morning.

Price: $39.99 with a −10% launch discount

The guessing is over — the Steam page now lists $39.99 as the base price, with a −10% launch discount live at release ($35.99). Verified prices by region on September 9, 2026:

| Region | Base price | Launch price (−10%) | | ------------- | ---------- | ------------------- | | US | $39.99 | $35.99 | | UK | £34.99 | £31.49 | | EU | €39.99 | €35.99 | | Japan | ¥4,980 | ¥4,482 | | Korea | ₩44,000 | ₩39,600 | | Taiwan | NT$888 | NT$799 | | China (Steam) | ¥166 | ¥149.40 |

The discount's end date has not been announced — launch promotions typically run one to two weeks, but we won't quote a deadline lowiro hasn't given. Check the Steam page for the current price in your region.

Platforms: PC only — still no mobile version

In Falsus is Windows-only at launch. The store page marks macOS and Linux as unavailable, and there is no mobile or console version announced. Planning your setup? We verified the official system requirements — minimum specs, Mac and Steam Deck status in one place.

The demo is gone — as promised

The free demo was removed from Steam on launch day, September 9, 2026, exactly as lowiro announced on August 31. The store page no longer offers a demo download.

What you built in the demo is another matter: lowiro never confirmed whether demo progress, scores or crafted cards carry into the full game, so treat them as practice — not investment. What definitely carries over is skill: the controls, judgement timing and card system logic are the same ones the full game launches with. Our demo guide stays up as an archive of the six-song v0.3.1 build.

What the full game shipped with

Verified from the launch build and the official announcement:

70+ songs — more than 40 of them originals, chart levels 1 through 11
a full-length ADV scenario fully voiced in Japanese, with 5 protagonists
the Card Crafting system — Iota, Blueprints and Traits layered on top of the rhythm gameplay
25 Steam achievements (most hidden until earned), Steam Cloud saves, Family Sharing and save-anytime support

The tracklist is being verified song by song — follow the live song catalog as it fills in.

Post-launch calendar: Tokyo Game Show 2026

Per lowiro's September 3 announcement and the booth details shared since, both Arcaea and In Falsus will be playable at Tokyo Game Show 2026 at Hall 3-C01, with lowiro staff on site throughout the show. This edition of TGS marks the series' 30th anniversary and its first-ever five-day run (September 17–21, with public days September 19–21). If you are near Chiba that week, it is a chance to play the game hands-on and meet the staff.

Showing up pays even if you skip the demo line: everyone who stops by the booth receives a key artwork folder — no play required — and trying In Falsus earns you a random character card on top. The booth also showcases Arcaea Version 7.0.
