Evaluation

Black Book: Prologue was a free standalone preview chapter released on May 5, 2020 to build anticipation for the full game, Black Book. It served its purpose: the full game launched on August 10, 2021. The prologue is no longer available for purchase on Steam — no purchase options exist — meaning it has been removed from the storefront. This is consistent with its nature as a promotional pre-release demo that was retired once the full game shipped. The most recent developer news post from July 28, 2025 announced a new game entirely (One-Eyed Likho), confirming the studio has moved on to new projects. There is no indication that the prologue will be restored or that any further content for it is planned.
