In Falsus launched on September 9, 2026 — and this page is our permanent tracker for everything lowiro publishes from here on: launch announcements, patch notes, hotfixes and event news. Every entry carries its date and an official source. No leaks, no datamined rumors — if lowiro didn't say it, it doesn't go in the changelog.

Before you report a bug

Most launch-week issues are environment problems with known fixes: our black screen fix guide, keys not registering guide and system requirements breakdown cover the common ones. If it is genuinely a game bug, the Steam Discussion forums are the right place — lowiro's devs have read them since the demo days.
