The Posthumous Investigation Review: a Murder Mystery That Has Me Suspecting Everyone

Disclaimer: The developer provided me with a game key for The Posthumous Investigation to review and feature in my content on the Nintendo Switch 2. Although I received the game for free, all opinions and experiences shared in this post are my own. Receiving a review key does not guarantee a positive review, and I will always aim to share my honest thoughts with my readers.

Have you ever played a mystery game where you start suspecting everyone, change your mind five minutes later, and then realize you might have no idea what's going on?

That's pretty much where I'm at with The Posthumous Investigation.

This is a detective mystery game built around a pretty wild premises: a dead man hires you to solve his own murder. You have limited amount of time, fourteen suspects to investigate, and a time-loop mechanic that lets you use everything you've learned to approach the next day differently.

And before I go any further let me tell you, I have been side-eyeing people left and right.

Before we get into the investigation, I do want to be transparent once again. The developer provided me with a game key to check out The Posthumous Investigation on the Nintendo Switch 2. Receiving a key doesn't mean I am going to pretend I love every part of a game. I will always share my honest experience.

Also, I started a completely new game to record footage for my video because I refuse to spoil where I am in my actual investigation. So the footage in my video shows the beginning of the game, while this review focuses on what makes the experience interesting.

What Is The Posthumous Investigation About?

The Posthumous Investigation is a detective mystery game set in 1937 Rio de Janeiro. You play a detective investigating the murder of a man who is already dead and the twist here he is also the one that hired you to figure out who killed him.

Just a normal Tuesday.

There are fourteen suspects, and everyone has their own schedule, relationships, and secrets. Your job is to investigate what happened, speak to people, collect information, and piece together the truth before time runs out.

The catch? The day eventually resets.

But you don't lose everything you've learned.

Instead, you get to take that information into the next loop and use it to make different decisions. So, maybe you missed an opportunity to follow someone, or a conversation revealed something important. Or maybe you discovered that somebody's story doesn't quite add up.

You can take what you've learned and try a different approach the next time around. And that's where this game starts getting interesting.

The Time-Loop Mechanic Is What Makes This Mystery Interesting

One of my favorite things about The Posthumous Investigation is how the time loop changes the way you approach the investigation. At first, you're basically walking into a situation where you know next to nothing. You're meeting suspects, learning who they are, paying attention to their schedules, and trying to figure out how all these people fit into the story.

Then the day resets.

Now you have information you didn't have before.

You might know where someone is supposed to be at a certain time. You might know which conversation you need to have, or you might realize you wasted an opportunity in the previous loop.

Now you can go back and do things differently.

It's a lot of trial and error, but in a way that makes sense for a detective game. You're not waiting around for the game to hand you the answer. You're learning how the world works and using that knowledge to make progress.

I really like the idea of being able to experiment with different approaches instead of being stuck with every decision you made the first time around.

You do have to pay attention. The game isn't going to solve the murder just because you keep repeating the day.

My detective badge does not come with a built-in answer key.

Fourteen Suspects? yeah, I'm Suspicious of Everyone

I am the kind of gal who plays a murder mystery game and starts accusing people in my head..

Someone says something weird and I am already convinced I've solved the entire case. Then somebody else acts different and my original theory is now in the trash. It's a whole situation.

With fourteen suspects to investigate. The Posthumous Investigation gives you plenty of people to question and plenty of information to sort through. You're paying attention to what people say, and making sure their schedules and stories line up with what you've already discovered.

One little detail can make you look at an entire conversation differently.

And because the game is build around repeating the day, you have opportunities to revisit situations with new information. Something that didn't seem important during your first loop might become important when you know a little more about the people involved.

I enjoy mysteries that make me think about details rather than pointing me toward the next obvious clue.

Just don't ask me who I think did it. I'm still investigating, and I'm not ruining my own mystery for a blog post.

The Investigation Boards Helps You Piece Everything Together

Important part of the experience is the investigation system. As you learn more about the suspects and their schedules, you need to keep track of what you've discovered and figure out how those details connect.

This is where the investigation board comes in. It helps you organize information and makes sense of the growing number of details you're collecting.

And when you are dealing with multiple suspects, different conversations, and a day that keeps resetting, having a way to track information matters.

You're not just trying to remember who said what. You're trying to understand how everything fits together.

I think this is one of the things that will appeal to people who enjoy detective games, logic puzzles, and mysteries where paying attention actually matters.

You'll need to think about what you've learned and decided what to do with it. It's less about rushing forward and more about putting the pieces together.

The Hand-Drawn Noir Art Style Is One of My Favorite Parts

Let's talk about the visuals, I really like the art direction in this game.

The game has a hand-drawn nori style that fits the detective story beautifully. The black-and white presentation give it an old-school mystery feeling, while the character designs and environments help establish the atmosphere.

It feels like stepping into a classic detective story.

The setting of 1937 Rio de Janeiro also gives the game a distinct identity. Instead of feeling like another modern detective game, it has its own visual personality that works with the story and the whole investigation.

I really like how the presentation encourages you to slow down and take in what's happening.

And yes, I will accuse a character of murder before I have enough evidence. That's between me and my imaginary detective license.

Is The Posthumous Investigation Repetitive?

Okay, let's be real about the time-loop mechanic.

The day resets, which means repetition is part of the experience.

You're going to revisit locations, encounter some of the same people, and repeat portions of the day while you experiment with different approaches. That's how the game lets you use what you've learned to make progress.

If you prefer games that introduce new action, environments, without asking you to revisit the same moments, this might not be your kind of game.

But if you enjoy games where you have to pay attention to understand how a mystery works and using information to uncover new possibilities, the repetition does have purpose.

You're not necessarily repeating the day just to repeat it. You're returning with a different understanding of what's happening.

Whether that stays enjoyable will depend on who much you like detective games and how patient you are with their mechanics.

Who Would Enjoy the Posthumous Investigation?

I think The Posthumous Investigation could be a good fit for players who enjoy:

• detective and murder mystery games where you investigate suspects and piece together clues.

• Time-loop mechanics that let you learn from previous attempts and change your approach

• Story-driven games with plenty of dialogue and information to pay attention to

• Logic and deduction where you need to connect details rather than simply follow a marker.

• Stylized indie games with hand-drawn artwork and a distinctive atmosphere

• Slower-paced gameplay that rewards patience, observation, and curiosity.

If you love trying to solve a mystery before the game reveals the answer, I think this one worth playing.

If you're looking for a fast-paced action game with combat, this isn't going scratch that itch.

This game is about investigating, thinking, and questioning every single person you meet.

The Posthumous Investigation on Nintendo Switch 2

I've been checking out this game on the Switch 2, and the game's presentation and investigation mechanics are what stand out to me the most so far.

The hand-drawn noir visuals give it a strong identity, while the time-loop system gives you a reason to revisit conversations and pay closer attention to the details you uncover.

It's also the kind of game where I want to take my time. I don't want to rush through a conversation and accidentally miss something that could be important later.

If you are interested in playing it, I recommend going in ready to read, observe, and experiment. This is a mystery that expects you to participate in solving it rather than sit back and watch everything unfold.

And please, for the love of all things detective-related, pay attention to those schedules. You might need that information later!

Before I Close the Case....

I'm really enjoying the idea behind The Posthumous Investigation. A murder mystery where the victim hires you to solve his own death is interesting, and adding a time-loop mechanic makes it even more intriguing.

I like that you're expected to pay attention, learn from your previous attempts, and use what you've discovered to approach the next loop differently. The hand-drawn noir style is another highlight for me for it gives the game a personality that fits the detective story.

And of course, I'm still working through my own investigation, so I'm not about to start handing out accusations or spoiling what I've discovered.

For now, I'm going to keep questioning people, watching those schedules, and not letting off anyone just yet.

If you enjoy detective games that make you think, The Posthumous Investigation is a game worth playing. And if you ever find yourself investigating a murder where the victim is the one who hired you, don't trust anyone not even the person who hired you.

Just saying.
