A World War II computer. An archive of lost books. A world-changing secret.
Narrative deduction meets audio drama in TR-49, coming January 21 to Steam (PC/Mac) and iOS — and it’s like nothing inkle has made before.
ABOUT THE GAME
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.
Written and created by the award-winning team behind Heaven’s Vault, Overboard!, and A Highland Song, TR-49 takes inspiration from by narrative deduction games like Type Help, Her Story, The Roottrees are Dead, and The Return of the Obra Dinn, and by audio dramas like The Magnus Archives and ars PARADOXICA.
