5 New Mystery Games to Play - June 2025
Early access, sequels, and a remastered spin-off
Before we begin: the Steam Summer Sale is active until July 10th — and that means big discounts on all kinds of mystery games!
The month of June was a bit slow for new releases, at least compared to the other months this year. Maybe because of the Summer Sale?
Anyway, it’s now the end of the month, so let’s go over a few mystery games released this month that stood out from the rest.
Decide 4 God (Early Access)
The final entry of the Abime Series. Six intruders and six captives share a high-tech prison where their moral dilemmas may lead them to a fate worse than death. Can they overcome the wiles of Empathy Systems? What dark secrets lurk behind that institution? When does knowledge become a curse?
The highly anticipated third and final game in the Abime Series by Miracle Moon. Currently in early access, the game features an overwhelming amount of content (at least dozens of hours, according to reviews) that spans various Zero Escape-inspired puzzle sections and branching story paths.
I played through some of the free demo: the initial escape room is on a turn-based timer, and the other characters in the room change locations and dialogue depending on the time. Your interactions with the characters during these sections influence the direction of the story. There are also mini-puzzles to solve, or you can let the other characters solve them for you (at the cost of time). I’ve only played a little bit so far, but it’s definitely well-made and enjoyable fun. The art and music are excellent, too.
But to fully enjoy the story (and avoid spoilers) it’s recommended to play through the prior two games in the series first: Head AS Code and Birth ME Code (both on big discounts for the Steam Summer Sale).
Parallel Experiment
Two detectives, one deadly experiment, a race against time. Each player only has one half of the puzzle. In this 2-player co-op puzzle game you can survive the parallel experiment only by working together.
The second chapter of the Unboxing the Cryptic Killer series, though it can be played without any prior knowledge. As the protagonists follow the trail of the Cryptic Killer, they suddenly become unwilling participants in his twisted experiment.
You will need two people to play this multiplayer mystery game. Both players must rely on their communication skills as they solve escape-room puzzles in parallel. Puzzle sections are separated by comic-book style cutscenes, with a stronger emphasis on story than the previous game.
Cellveillance
"Cellveillance" is a detective drama entertainment product, you will visit the apartment every day, and the entire apartment is responsible for everything that happens in the apartment, a mysterious organization asks you to return the information of the residents.
From the creators of FMV mystery game Game of Fate (a game I previously covered) comes a new FMV game, with horror/romance elements. Story-wise the game is unrelated to Game of Fate, though I believe some of the actors are the same.
You play the role of an apartment manager who installed security cameras in each apartment, spying on your tenants and selling their information to a mysterious organization to pay for your mother’s medical debt. You quickly learn that the residents aren’t as innocent as they first appear, and you are thrust into a moral dilemma: cooperate with the police investigation, or keep these secrets hidden to pay back your debt.
The gameplay is similar to this studio’s previous FMV games, but with a stronger emphasis on the computer simulation genre. You can choose which cameras to watch, and which emails or text messages to send, which influence the outcome of the story.
Please note that due to dark topics and sexually suggestive content, some scenes may not be suitable for all players.
Kill The Clock (Early Access)
Kill the Clock is a narrative time-loop mystery adventure where you relive the same week to solve a murder that keeps changing. Customize your character, roll dice to influence story outcomes, and uncover the truth—before time resets again.
Another mystery game I previously covered is now in early access.
The game begins with character creation: customizing the visuals, choosing your class, and distributing skill points. Not only does the story change based on your choices, but also based on the success or failure of “skill checks” based on dice-rolls. Sometimes you will have an opponent with their own stats and dice-rolls that you need to defeat.
All of those mechanics — combined with the typical investigation and interrogation gameplay you would normally find in a mystery visual novel — make for a really unique experience.
According to the store page, each chapter contains multiple endings based on your decisions, actions, and relationships with characters. Replaying the game reveals different culprits and methods of murder, delivering a unique experience each time.
RAIDOU Remastered: The Mystery of the Soulless Army
The story of apprentice detective and Devil Summoner extraordinaire Raidou Kuzunoha XIV returns in this remastered classic! Call upon your demons to solve supernatural mysteries and dispose of enemies.
Although not a new game, the remaster apparently made a lot of changes from the 2006 original. A spin-off of the Shin Megami Tensei series, much of the game involves fighting in real-time combat encounters, but the story has a strong emphasis on solving a mystery as a supernatural detective.
Outside of combat, there are investigation sections where you can summon demons to hunt for clues and uncover the truth using their unique abilities.
Key takeaways for developers
Some lessons these games can teach developers:
Staying focused in a niche (co-op escape games, FMV games, etc.) lets you frequently put out new games while maintaining your audience. You end up getting good at making that specific type of game, and people keep coming back for it.
Putting games into early access is always tricky, but it can be helpful when your game is really complicated and needs feedback (lots of text, many branching paths, unique mechanics, etc.).
Don’t forget about your old games. After a long enough time passes, remaster it with improvements to satisfy old fans and reach new ones.
