TR-49

A voice is saying your name. A WWII-era machine, long hidden in a church basement, whirs to life. Through a crackling speaker, a man asks you to find a stolen book. He only knows the title. Time is running out. The machine, built by Bletchley Park engineers Cecil Caulderly and Beatrice Dooler, contains a vast archive of obscure books, letters, and journals fed in over fifty years in an attempt to crack the code of reality. As their lives fell apart, the machine kept working. Your task is to navigate the archive, linking its texts to uncover the creators’ secrets.

Navigate a living archive — explore an expansive database of rare writings and correspondence. Deduce connections between disparate sources, map hidden threads, and locate sources that reveal who authored the books and why the machine was built. Your choices shape the path you take through the archive, making every discovery feel like a new clue in a larger puzzle. The ultimate aim is to find the book at the core of the machine and decide whether it should be destroyed or rewritten by your intervention.

Dynamic narrative, reactive dialogue — talk with your handler at any moment. The audio drama responds to your exploration, adjusting tension, pacing, and revelations in real time. The interpreter behind the speaker guides you, but your role and fate inside the mystery are yours to determine.

Atmosphere and production — the game blends intricate puzzle solving with immersive audio storytelling. Voices bring the archive to life, including Rebekah McLoughlin, Paul Warren, and Phillipe Bosher, with an original soundtrack by Laurence Chapman. The experience channels the spirit of narrative deduction games and audio dramas that have defined the genre.

Origins and influences — TR-49 draws inspiration from The Roottrees are Dead, The Return of the Obra Dinn, Type Help, and Her Story, while echoing the mood of The Magnus Archives and ars PARADOXICA. Created by the award-winning team behind Heaven's Vault, Overboard!, and A Highland Song, TR-49 invites you to think through links, not just actions, and to see how a single stolen book could alter the fabric of reality.
