About the Game
Where Conversation Becomes Combat
Strangers. One killer. No witnesses.
You step into a room. Around you sit others—each claiming innocence, each hiding something. Someone here committed murder. Someone here is still dangerous. And the only way out is through the truth.
But in PERDIFY, the truth doesn't want to be found.
"What if a murder mystery could lie back?"
Traditional mystery games present puzzles with predetermined solutions. The killer is always the same person. The clues are always in the same places. Once you know the answer, the magic evaporates.
We asked a different question: What if the suspects could think?
PERDIFY represents a new kind of narrative experience: AI characters with authored motives, memory, and pressure points. They respond to you. They remember what you asked three conversations ago. They notice when you're circling back. They get nervous. They get defensive. They get creative.
Every case is crafted by hand, then handed to AI that improvises within it. The truth model is fixed for each run: timeline, evidence, alibis, and what each character can know. The performance changes. The case facts do not drift.
Each release case is validated against an authored truth model before it ships. We don't hide solutions behind pixel hunts or obscure logic leaps. The evidence has to implicate the responsible character, the alibis have to survive the timeline, and the contradictions have to come from the mystery rather than the model losing context.
Our AI characters aren't chatbots wearing costumes. Each has a complete psychology: fears, desires, secrets they're protecting, lies they've rehearsed, and facts they are allowed to know. Their dialogue can bend under pressure, but their answers are grounded in the same case record the player is investigating.
Wrong accusations carry weight. Accuse an innocent, and you lose an ally—someone who might have helped you identify the real threat. The game doesn't reload. The dead stay dead. Your mistakes become part of your story.
Each case is authored by hand, but the interrogation never plays the same way twice. The truth model stays fixed while the questions, pressure, dialogue, and counter-moves change around it. You can't memorize PERDIFY. You can only get better at reading people—real or artificial.
Building PERDIFY required solving problems that don't have precedents. How do you create an AI that can lie convincingly—but not too convincingly? How do you generate mysteries that are always solvable but never obvious? How do you make interrogation feel like a skill that improves with practice?
Our approach borrows from three disciplines:
The result is a game where you're not clicking through dialogue trees—you're conducting an investigation. You're reading body language. You're catching slips of the tongue. You're becoming a detective.
Interrogate using your actual voice or type your questions. The suspects respond in kind.
The case fights back. Between rounds the imposter plants evidence, corrupts clues, and turns suspects cold.
Track alibis, map contradictions, and build your case with an intuitive investigation interface.
Solve a Quick Case in one sitting, or follow a Full Case across days. Your progress is saved.
Perdition /pərˈdɪʃən/
noun — a state of eternal damnation; complete ruin or destruction
PERDIFY takes its name from perdition. In this game, someone has already been destroyed. Your job is to ensure justice finds the one responsible—before they destroy anyone else.
The suspects are waiting. They've rehearsed their stories. They think they're prepared for your questions.
Prove them wrong.
