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 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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 decent thriller puzzler for skimming through an esoteric archive for information and oddities and then piecing everything together in a conclusion that can have multiple endings. All of this is bogged down, however, by the baffling decision to have half of the relevant story dumped onto you via radio calls in the first twenty minutes. You'll be trying to work and get prompted to hit space over and over and over again (or just letting the conversation play out without input) as Abbi and Liam slowly and painfully drag their way through a miserable exposition dump. This would be fine in bursts and at designated breaks in the gameplay but the gameplay doesn't "pause" to have a moment of exposition, and the semblance of "bursts" it has are moments that are 1 minute apart. [spoiler]Later on an enemy soldier will take out Liam and ragebaits you over the radio over and over again until he literally just gets tired of searching and straight up leaves. There's no huge reason for this to be dragged out, he just says over and over "I'M GONNA FIND YOU WHY DON'T YOU COME OUT I WANNA KILL YOU ALREADY" and it's boring as ♥♥♥♥ to read in the subtitles let alone listen to.[/spoiler] This in fact got me so fed up that I ended up just hunting numbers and titles for the rest of my playthrough with no care for context. One quick look at a guide after the fact and one misses how much WEIRD ♥♥♥♥ points towards the source of the major conflict. It's an okay game, just focus on what is on the screen rather than what is in your ears.

This review is especially made for those who like to get all the achievements in games. Minor spoilers ahead. TR-49 is another great detective game by inkle that takes place inside a special computer and your goal is to find a secret entry, jumping from book to book, cross referencing journals and other publications, until you can associate the entry code with the publication’s title. The computer’s input is just a pair of two letters for the author and two numbers for the year of publication, but soon you’ll find out that the numbers can also mean something else. I won’t spoil the story because even after reaching the endings some facts are still left for interpretation and I find it fascinating. The visual style of the computer itself is very retro and seems to be based on Alan Turing prototypes that were used to break German ciphers. The screen itself is also very strange, resembling more colored vinyl than a CRT or LCD monitor. Besides this, you’ll only look at files and the basement where the game takes place. To complete the game and discover everything you will need to read a lot and pay attention to the details referencing years, encounters and family relationships, but you can also brute-force the discovery of new entries by guessing the publication dates. Often I’d do this besides paying attention to what was written but eventually I got everything. If you want to save time, here are a few hints:[spoiler] Most authors have an index with all the books they published, the code is their two name and surname letters and the last two digits of the year they were born, but the second letter code will change after the female authors get married and widowed or divorced. The entries with a red dot in your list mean there are links still left to discover[/spoiler]. The achievements are all story related and are awarded for discovering all entries and getting all the endings. The hardest ones will be getting two of the endings [spoiler]that aren’t in the list you get after discovering everything, so here are some clues: one of the endings requires erasing the earliest theoretical concept the machine is based upon, the other requires erasing the technical knowledge of how it works[/spoiler]. [b]Achievements:[/b] [b]How many:[/b] 21 Achievements. [b]How much time:[/b] Around 8 hours, on my own, without a guide. [b]Game difficulty:[/b] Medium, without a guide, but very easy with one. [b]Achievements’ Difficulty:[/b] Medium, no missable achievements. The trickiest ones are related to the different endings you can get, [spoiler]4 + 1 in total[/spoiler]. [b]Overall opinion:[/b] TR-49 is another great game by inkle with a compelling and complex story but with a darker tone than previous games. It requires persistence and a lot of trial and error to discover everything on your own, but you can use a guide for clues and the solutions [b]Join and follow my group [u][url=store.steampowered.com/curator/42556190-Ribbon-Hunters/] Ribbon Hunters[/url][/u] for more suggestions and reviews of easy indie games to get all the achievements.[/b]
A good mystery game with some faults. The story is great. I think some of the much later puzzles don't entirely make sense. Also, you're going to be bombarded with a lot of information and only able to pursue one path at a time. There isn't a search function to go through text that you've accessed before. That would have helped me when I came back to the game after a day and couldn't remember the start of a specific breadcrumb trail I left alone.
A very unique and mysterious game similar to the book "The Ship of Theseus".
BibTeX: The Game. Gave me flashbacks from my thesis days. 10/10
Очень интересный пазл по расшифровке кодов. Прям захватил. Сюжетно ты примерно понимаешь что происходит, а потом идёшь в гайды и читаешь парочку обьяснений, чтобы каринка сложилась полностью.
I was hooked from start to finish
Overall, don't think I can recommend this one. It's incredibly ambitious, and likely I'm just not smart enough to keep up with it. I got to 48/50 records and hit a point of no progress for hours. The bulk of records and branching paths just became too much. I respect the game providing the player complete liberty, but it boiled down to brute force of codes that become a chore when no progress could be made elsewhere.
Wonderful game for those who like research/investigation-style games
It's like someone read Danielewski's [i]House of Leaves[/i] and figured out a way to make a game out of it.
