Current download status
The official Steam app page currently presents the paid Early Access game. It does not expose a “Download Demo” or Prologue link.
A separate Steam search for the exact Prologue name returned zero store results during the August 29, 2026 verification. For that reason, this guide does not send readers to an unofficial download mirror.
Why older results mention a free Prologue
Pre-release videos, search results, and ProtonDB reports document a playable Prologue/demo. Multiple community reports are about three months old and explicitly call it a free Steam Prologue.
Those records help explain the search demand, but they do not prove that the download remains available after the Early Access launch.
