About
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.
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.
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).
TR-49 takes inspiration from narrative deduction games like The Roottrees are Dead, The Return of the Obra Dinn, Type Help and Her Story, and from audio dramas like The Magnus Archives and ars PARADOXICA.
Written and created by the award-winning team behind Heaven's Vault, Overboard!, and A Highland Song.

Short but interesting deduction game in the style of Her Story or Immortality. Navigating this book catalogue and discovering all the books and commands and passwords was surprisingly challenging, especially towards the end. It wasn't that hard to figure out what I was supposed to do and what are the "rules" but at some point you do feel like you are out of leads. At least I did. I really enjoyed reading everything and understanding the events that lead to where we were and what my end goal is, even if I did stumble on a few key moments or information by chance.
A short little puzzle game reminiscent of the old HTML link games like E.B.O.N.Y. Your job is to find document codes and associate them with their titles. Along the way, you begin to piece together the story of a world gone very, very wrong, and discover how to set it right. Bonus: Plays great on a potato.
Really good deduction game with great writing as usual from inkle. I might be too stupid to figure it all out but what I did find was excellent!
excellent game! The story unfolds organically and I liked how nothing is really given. Clever code system
This game is a tricky puzzle featuring books, so, as a puzzle-loving librarian, I really enjoyed it! I found most of the items myself and then did need some guided assistance toward the end. Taking notes along the way helped me a lot. It's amazing how much gameplay there is for such a simple, mostly static game interface! This was a pretty unique experience, though somewhat similar to other games I've loved, like Strange Apothecary and Strange Antiquities, where you're inputting data/items into a static screen and getting more data/items to help you continue solving puzzles.
The inspiration from Type Help (aka The Incident at Galley House) is most obvious, in that it is a game where you need to interact with a machine holding a broad story and can only expose small chunks of the narrative through noticing important details in the sections that you've already seen. I appreciate that this game is a little less linear than its inspiration whose full interface has a bit more subtlety, which makes the environment feel much more open. Like Type Help, it takes a big chance on the overall story, and I think it sticks the landing a little better (and much much better than Her Story, to give another game in the same specific genre). I got through my initial playthrough in about eight hours, so it passes the dollar per hour test even at full price. And I've got enough enthusiasm to play through the game again to finish up all of the achievements that I missed the first time through. If you're in a mood for interactive fiction where figuring out who you are and how the interface works is part of the story, then this is a fantastic way to scratch that itch.
Cheap and interesting sci-fi story. But you have to like puzzles and reading or use a guide. What you see is what you get.
So in all seriousness, how many books does the TR-49 have?
A really neat kind of puzzle that asks you to think in layers. You're trying to both logically think about names and dates, and also narratively think about how events tie together, while unraveling a fascinating story behind it all. I've played a lot of puzzle games and I don't think I've played one quite like this. I absolutely recommend avoiding walkthroughs or spoilers; it would really defeat the purpose of playing the game at all. You have an in-game notebook that keeps track of your progress, but depending on how invested you want to get, I'd say it's worth it to keep your own notebook; the game's notes don't quite connect everything that you might be able to piece together in your mind until you make a definitive connection. Hard to explain without giving too much away, but you'll see. Don't worry too much about time - I promise you are given everything you need to follow the trail and get to the end. For 7 bucks, I'd call it at least a 9/10, only reason I'm hesitant to go 10/10 is I wish it was a little longer. That said, at 2.9 hours I've only completed the mainline necessary to get an end screen. I do plan on 100%ing it so maybe I'll feel differently after I piece it all together and see another ending!
An excellent entry into the deduction puzzle genre.
