About This Game

Grigore believed in Kudesh's order, the will of the Great Mycelium, and faithfully served as Mortimarch Sorge's personal assistant.

Then he became a Rejected.

Mycelium Protocol: Prologue is a linear visual novel blending cyberpunk and biopunk. Live through several pivotal days in Grigore's life, discover everyday life in the Upper City and the process of symbiotic grafting, take part in the mysterious Club's debates, and watch the world he knows slowly begin to fall apart.

The Prologue is a standalone, completely free game introducing you to the unusual world of Kudesh and the people who inhabit it.

The story leads to a single ending, but your decisions will have consequences that carry over into the main story of Mycelium Protocol.

  • A complete multi-hour story, available for free;

  • A setting blending cyberpunk and biopunk;

  • Choices whose consequences carry over into the main game;

  • A world of fungal symbiotes, neural implants, and buried secrets;
