You are Thomas Ward and that is all you remember.

Enter the Cathedral of Sorrow. The simple wooden walls hide a twisted labyrinth housing the deprived and the depraved and an unknown force watching your every move and adapting the nightmare within. Face your fears, press on against the darkness and stare back at the abyss.

Cathedral of Sorrow is an experimental horror game starring Magnus Bruun (Assassin's Creed: Valhalla). Combining frantic first-person gameplay and immersive storytelling with procedural level generation and sophisticated machine learning, the Cathedral scars your mind and breaks your heart using real artificial intelligence and machine learning to profile your fears and adapt the game to break you.

Immerse yourself in a story of algorithmic cruelty, and how the systems we design to help us turn into jailers. Seek out those trapped in the nightmare with you to learn the truth of what happened to you. And should you fail, the Cathedral will embrace you once more, eager to surprise and terrify you in new and malicious ways.

AN EVOLVING NIGHTMARE

The baleful spirits haunting the Cathedral are hellbent on tormenting you. The game dynamically tracks and evaluates your playstyle using a machine learning algorithm trained to detect human fear to best decide when, where, and how to scare you next. Every whisper in the darkness and terrifying encounter is tailored to your fear profile for a unique and ever-changing horror experience.

EMOTIONAL PROBLEM SOLVING

The Cathedral plays host to a range of all-too-willing prisoners. To penetrate its dark heart and uncover its secrets, you will need their help.
