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.

I did find that I was especially confused at the start about the codes that unlocked notes within the pages, but I just looked at a guide to get a quick answer and went back to my mindless back and forth. Despite referring to it as such I did enjoy the process and the game. Could see the process being improved a little, I have terrible memory and mix things up a lot, but the game sorts most of it effectively for you in records. Worth giving it a shot.
What a great time, Good brain teaser
If you enjoy puzzle games this one is pretty great you don't really need to use a walk through on it I only got stuck once and that one was tricky because the author was only briefly mentioned, For a one room mystery game I enjoyed myself greatly.

TR-49 is an odd game to review, because it's so centered around text, but I'm not entirely sure the text amounted to much in practice. Not to say it's bad writing. There's some interesting developments, and it's all presented in a clear, concise fashion. It all serves the game goals by being interesting to puzzle through. But it doesn't really amount to much. There's basically 3 narrative layers, and none of them ever really go much of anywhere. There's the protagonist who serves as your avatar, who basically just spends most of the story trapped and scared and who we really don't get to know. There's the people who managed the super computer, whose relationship I actually really liked, but didn't really progress towards anything, and then there's the relationships between the authors who are archived in the computer, which were interesting, but felt like they were building to a much bigger reveal than we actually got. All 3 layers feel like they're scratching around the edges of a much bigger idea without much of a payoff, which felt frustrating. But fortunately, I'm a big style of this sort of puzzle. Connecting the dots and figuring out the labels for each of the documents was genuinely fun and it felt good to get an entire set of files dealt with. For any fan of this growing genre of deductive games like Obra Dinn, The Case of the Golden Idol, or Outer Wilds this is a pretty easy recommendation, as it will scratch that itch, and frankly there's only so many of these games out there. I just wish all that fun work had amounted to an ending that hit harder.
This game is so fun and interesting I played for like six hours without realising. I did cheat a bit, I like puzzles but I am really not good at them so I needed a bit of extra help. It is so incredibly intriguing and the story is so strongly written its ridiculous. The only thing is some of the links between finds were pretty vague and at a point hard to justify, and the endings can be difficult to figure out but also like I'm not that smart so who cares
Absolutely awesome game. I have enjoyed the last 6 hours simply trying to get through the archive. A nice story, with an excellent gameplay behind it. Among my favourite games of all time. By far.
This game is for a select few who find piecing together mysteries while archiving, and getting to do that scratches your brain... Scratches your brain real good... this game is for you, and you are my tribe. The plot is engaging, the atmosphere is dark and mysterious, and the gameplay is deeply satisfying as an Archivist's Mystery. Highly recommend.
An excellent entry into the deduction puzzle genre.
An enjoyable experience, intruigue, logic, puzzling, well written, well acted, and a satisfying experience. Short but well worth the experience.
Another excellent Inkle game. I don't think I found all the secrets, but I still had a great time with the system.
