Evaluation
Doorways: Prelude is the first installment (Chapters 1 & 2) of the episodic Doorways series by Saibot Studios. The game launched on September 20, 2013.
The full episodic series has been completed. The final chapter — Doorways: Holy Mountains of Flesh (Chapter 4) — launched on August 10, 2016, completing the saga. A New Year's post from December 31, 2016 explicitly confirmed that Doorways was "finally finished" and that the studio was moving on to new projects.
Since then, Saibot Studios has shifted focus entirely to new titles, most notably Hellbound (announced November 2017) and Tenebris Somnia (referenced in their January 2025 recap video). The April 2019 post made previously paid DLC content free, which is consistent with a completed, legacy title being maintained but no longer actively developed.
The store description still references the episodic structure, but all three parts of the series — Prelude, The Underworld, and Holy Mountains of Flesh — have been released. There are no unreleased DLC entries and no announced future content for this game. Doorways: Prelude is a complete product, and the broader Doorways story it belongs to concluded in August 2016.
Evidence
Developer explicitly stated that Doorways was 'finally finished' and that the studio is moving on to work on something new.
The final chapter of Doorways (Holy Mountains of Flesh, Chapter 4) launched, completing the episodic series. All prior chapters including Prelude were put on sale.
