Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“I'm launching in Early Access to collaborate with players while the game’s AI-driven systems, content, and streaming features mature. Early Access lets me gather real-world playtesting to find edge-cases that automated tests miss, tune AI guardrails, and evolve story endings and Twitch integration based on player feedback. I am committed to regular updates, active community discussion (Steam Discussions + Game Forum), and transparency about progress — our goal is a polished 1.0 release that includes finished ending scenes, stable Twitch features, improved AI robustness, and wider platform support.”

Approximately how long will this game be in Early Access?

“2 months.”

How is the full version planned to differ from the Early Access version?

“We plan to add additional features not currently in the game, such as the game endings, twitch integration, and an improved user interface.”

What is the current state of the Early Access version?

“The game still does not have twitch integration, outro scenes, and community features. It is in a late prototype stage. You can find more information about the current game state in the "About This" section of the Steam page.”

Will the game be priced differently during and after Early Access?

“Price may be raised by 25% at full release.”

How are you planning on involving the Community in your development process?

“Community feedback directly shapes development priorities. Bug reports and edge-case AI behavior discovered by players are triaged and scheduled into regular patches. Feature requests are discussed openly in the Steam forums and the game Forum, where we run polls and feedback threads to guide design decisions such as AI constraints, balance tuning, content additions, and Twitch integration features. Larger changes are tested in public playtest branches before release, ensuring players actively influence the game’s direction throughout Early Access.”

About This Game

THE FIRST AI DETECTIVE GAME THAT DOESN'T LIE.

Developed by a former Meta AI Engineer, Detective Turtletop solves the biggest problem with AI gaming: Hallucinations.

In other games, you can trick the AI into confessing to a crime they didn't commit, or inventing evidence that doesn't exist. Not here.

This game utilizes a proprietary "Truth Table" Architecture. The murder mystery is generated via hard code—the killer, the weapon, and the location are mathematical facts. If a suspect is innocent, no amount of prompt-hacking will make them confess. If they are guilty, they will lie to your face until you present the hard evidence that breaks them.

THE CASE: CINCINNATI, 2016

It is the darkest day in history. Harambe is dead.

You are Detective Turtletop, a hard-boiled reptile with a lust for justice. You have 3 hours to interview the witnesses, collect physical evidence, and sign an Arrest Warrant before "Big Zoo" moves in to sweep the murder under the rug.

THE SUSPECTS

You aren't just chatting with generic bots. You are interrogating high-fidelity personalities with hidden motives:

  • Dr. Z: The zoo's head scientist and an insufferable Reddit Moderator who thinks he’s smarter than you.

  • Brenda: A "militant" vegan activist who may or may not be part of a secret cult.

  • Silverback Stan: The rival Alpha who was tired of living in Harambe's shadow.

  • Ms. Hastings: A terrible mother looking for a lawsuit payout.

  • COVID-19: A mysterious figure coughing uncontrollably who seems obsessed with the year 2020...

KEY FEATURES

  • Type Anything: No dialogue trees. Use your own words to interrogate suspects.

  • The Stress System: Watch the suspects closely. If you ask aggressive questions or present damning evidence, their Stress Level rises. This will change how they act and respond, which may or may not be to your favor....

  • Procedural Mystery: The killer, the murder weapon, and the evidence locations are randomized every time you play.

  • Hard Logic: Suspects know what evidence exists in the world. They won't invent fake alibis that contradict physical reality.

  • Live-Generated Responses: Powered by a world-class AI, dialogues are generated in real-time. No two playthroughs are ever the same.

DISCLAIMER:
This game requires an active Internet Connection to generate suspect dialogue.
AI characters may occasionally behave unpredictably.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

This game uses live-generated AI to power the dialogue of the suspects. When you type a question, the response is generated in real-time, ensuring that suspects react dynamically to your specific accusations and evidence. An active internet connection is required to play.
