PERDIFY

Where Conversation Becomes Combat

The Premise

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.

The Vision

"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—one where AI characters possess genuine autonomy, memory, and motivation. They don't follow scripts. 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. Who the imposter is, how they cover their tracks, how the room reacts to you—none of it is fixed. Every interrogation is a live performance between human intuition and artificial intelligence, and no two unfold the same way.

Design Philosophy

01Mechanically Fair

Every killer can be caught. Every innocent can be proven. We don't hide solutions behind pixel hunts or obscure logic leaps. The evidence exists. The contradictions are real. Your job is to find them through conversation—not to guess what the designer was thinking.

02Narratively Authentic

Our AI characters aren't chatbots wearing costumes. Each has a complete psychology: fears, desires, secrets they're protecting, lies they've rehearsed. When they contradict themselves, it's because humans contradict themselves. When they deflect, it's because humans deflect.

03Emotionally Consequential

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.

04Never the Same Twice

Each case is authored by hand, but the truth underneath is dealt fresh: who the imposter is, how they lie, and the counter-moves they make between rounds. You can't memorize PERDIFY. You can only get better at reading people—real or artificial.

The Craft

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:

  • Screenwriting: Character psychology, subtext, the rhythm of revelation and concealment
  • Game Design: Fair challenge, clear feedback loops, meaningful player agency
  • Forensic Psychology: Real interrogation techniques, deception detection, behavioral analysis

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.

The Name

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.
