TR-49

About this app

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, created by Bletchley Park engineers Cecil Caulderly and Beatrice Dooler, contains a vast archive of obscure books, letters, and journals fed in over the span of fifty years in an attempt to crack the code of reality. As their lives fell apart, the machine kept working. Navigate the computer’s archive. Link its obscure texts and uncover its creators’ secrets. Communicate with the man behind the speaker to figure out your role in this mystery. Destroy the book at the core of the machine — before it’s too late. NARRATIVE DEDUCTION - Deduce links through the archive to locate hidden sources. - Unravel the stories and unearth the secrets of the books’ authors and the machine's creators. - Map the archive and find the book that will rewrite the world. INTERACTIVE AUDIO DRAMA - Talk with your handler at any time, creating a dynamic audio drama that responds as you explore. - Featuring the voices of Rebekah McLoughlin (The SCP Archives, Eternal Threads), Paul Warren (A Highland Song, Viewfinder, The Séance of Blake Manor) and Phillipe Bosher (Baldur's Gate 3, Doctor Who, The Hitchhiker’s Guide to the Galaxy). - Original soundtrack by Laurence Chapman (A Highland Song, Heaven's Vault, The Mask of the Rose). INSPIRATIONS TR-49 takes inspiration from narrative deduction games like The Roottrees are Dead and The Return of the Obra Dinn, and from audio dramas like The Magnus Archives and ars PARADOXICA. Written and created by the award-winning team behind 80 Days, Heaven's Vault, Overboard!, and A Highland Song.

The CALIBRATION revision Thanks to everyone who's been playing TR-49 so far! We've been busy collating feedback, tightening screws and replugging wires. The Settings menu now offers two new tick-boxes: 1) Reduce Hints For those who like a more deductive, less-directed experience, you can remove the in-game hint systems and reminders. Once you're through the tutorial, it'll also remove the highlight state from the intercom, to reduce the pressure to use it (unless you feel like talking). 2) Remove Glitch Effects Everyone loves old tech, but it's not always comfortable. If the screen movement was giving you issues, tick this box to reduce the ambient animation for a more crisp on-screen reading experience. We hope this lets you enjoy TR-49 the way you want to.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
