Dear fans and friends,

Over the past few years, we’ve poured our hearts into The Posthumous Investigation, striving to create an experience worthy of Machado de Assis’s brilliance.

The response we’ve received both from Brazil and abroad has been beyond anything we imagined. At Tokyo Game Show, we watched players from across the world fall in love with our characters and noir atmosphere inspired by classic Brazilian literature.

That incredible reception inspired us to go further.

To make sure players everywhere can experience the story from day one, with Japanese and Chinese translations, we’ve decided to move the release to Fabruary 2026.

We know waiting isn’t easy, but this decision is about respect for our community for everyone who’s supported us from the start and for new players discovering Machado’s world for the first time.

We want everyone to begin this investigation together, on the same day, in their own language.

Thank you for your patience and support.

We’ll be back soon with updates and a launch we promise will be worth the wait.

With love,

Mother Gaia Team

• LudoNarraCon You heard it, we'll feature in another incredible festival. This time we're part of LNC's Official Selection! LNC is a big annual event dedicated to narrative games, and we're thrilled to be a part of it. It's fully digital, and will feature several talks and panels on the vast theme of stories in games. This year, developers of the games from the Official Selection will also be broadcasting. Which leads us to the second news...
• Behind-the-scenes We at Mother Gaia will be broadcasting brand new content during the event. Save the date: May 11th is the day! You will be able to watch us directly through our Steam page. We're going to give a small peak behind the curtains of this game that is so special to us, and we also want to have a casual chat while showing some gameplay.

• #LGF24 If you've been following our socials, you already know we're part of London Games Festival's Official Selection for this year! We're thrilled to have our game featuring in physical locations overseas, and we hope Londoner aspiring detectives can find something they like in our noir Rio hills. If you haven't been following our socials, then what are you waiting for?
• Demo update Since Next Fest, we've been hard at work organizing the rest of our development (which should take us no more than 9 months, if everything goes smoothly). Along with that, we managed to squeeze in a lot of bugfixes and polish that directly affected our demo, so we thought it would be a good opportunity to improve your experience a bit before actual release. Since we're going to be featuring in a festival very soon, might as well tidy up the place a little bit, am I right?

• New animations: for our regular dialogues outside of interrogations, as well as background characters. For example, some folks now run from the rain, while others keep their cool thanks to their handy umbrellas!
• Sound: we managed to give proper attention to sound work in these past weeks. Some bugs related to that are fixed, and some characters have new music.
• General stability: we fixed a load of bugs, typos and dialogues, so the overall experience is considerably smoother now.

Hello, fellow detectives!
