Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 1.43/day in the week to Aug 10 → 3.71/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
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.

A unique puzzle game linking stories with codes. A struggle at first, but very rewarding. Be prepared to stare at mostly one interface and then switch to an in-game notebook for reference.
Interactive audio-drama comprised of navigating a fake-OS (insofar as what could be considered an 'OS' in WW2-era computers), deciphering the organizational system of files on that OS, in pursuit of a single archived book buried somewhere within the machine. It is one of those puzzle games structured in the manner where, once you know how its internal systems are sorted, and have deduced the information needed to find the singular objective, completing the game becomes trivial - and thus and further information is a spoiler, mechanically as much as narratively. Ultimately, an excellent, dense, read, dripfeeding its story in asynchronous portions across some-fifty years of writings. The obtuseness of that information, and the deliberate withholding of what the plot and game actually are until you're near halfway through it, will prove frustratingly-paced for some, but remains a very-specific game that, if it clicks, will *click*, and click *hard*, if of your particular niche.

I have to echo the others who don't recommend this game. It's not the story or the idea of this game that's a letdown, it's the interface and execution. - Dialogue should happen at distinct times and complete without me having to press a button to have it continue in the middle of me trying to read an entry. - You have to enter user IDs to expand entries. It shows you the person in the entry. Once you have that ID, you should be able to just click the entry and read the addition. This is inconsistently done and you often have to enter the same ID again and again for each entry. Overall, I'm interested in the story, but it's a chore to play.
Okay "five hours played" really elides the fact that I got through the entire thing in one sitting, went back to check out a different ending, and will probably play it again from the beginning just because. It really is that good. I think I have a game hangover from not being able to play it for the first time again.
Played this with 3 friends over discord over 3 sessions, theorizing, having fun, not understanding a core mechanic but just absorbed in the concepts in the story long enough. Definite recommend if you can stomach being a librarian sorting through data entries and possibly getting stuck if you miss out on some info.
Undeniably fascinating.
A fascinating puzzle game with a very interesting loop. 9/10, although the endings leave something to be desired. Definitely does not hold your hand, and a couple of the puzzles are a bit obtuse, but generally not frustrating, although I have a couple minor gripes about the interface.
I enjoy games where you have to dig for clues and logic out solutions, and this game is ALMOST that. But there is no hint system and some of the results ended up requiring a little too much guesswork. If you're going to give it a go, I recommend taking good IRL notes because swapping between pages to find a clue you glossed over gets kinda frustrating. But my big issue with this game is the story. You unravel some information through the files you read on the computer, but the information about what's going on in the world and who you are is given by some guy over a radio while you're trying to read. And then later there's another guy blathering over the radio while you're still trying to read computer files! It really got kinda frustrating. The ending is also a little obtuse, but also I was so frustrated with flipping through files that I didn't care to go back through everything to find the "correct" answer so YMMV. All-in-all I think this had an interesting concept, but it was not delivered well.
How come I discovered this game in some bundle somewhere, and I never crossed it before, even though I am constantly in search for puzzle titles? Or maybe the game is destined to be a hidden gem, not easy to find, similar to finding a secret book in a library? So, as for the players, I can assume they will fall in two category: either really dislike it or really like it. If you are one of us, then be prepared for a joyride trying to find your way between random pieces of text. Reading isn't my hobby, and I never read fiction, BUT I read each of the text segments in this game, and I enjoyed it. This is a unique maze that you encounter once in your lifetime. Blue Prince? Lorelei and the Laser Eyes? But in books. An experience that lives even after the game is completed. Thank you NK-13
Very good in-depth puzzle game. Great for a rainy afternoon, coffee, and a partner with a different shade of autism to your own. 10/10 GREAT ENDINGS
