The Premise
You step into the room. Strangers stare back. Each claims innocence. One is lying. Someone here has blood on their hands—and they'll say anything to keep it hidden.
In PERDIFY, you are the interrogator, the detective, the final judge. Each suspect speaks with their own voice. They remember your questions. They adjust their stories. They watch you watching them.
Your weapon is conversation. Your evidence is contradiction. The killer knows you're hunting them. They're hunting you too.
Can you find the liar before the game finds its next victim?
THE MECHANICS OF PARANOIA
Case File · Confidential
The Investigation
Eight steps from the door to the confession. None of them are easy.
02 — The Brief
Step Into the Story
Every case opens like a noir film. A judge stabbed in a stalled elevator. A hotel in total darkness. Seven suspects, twelve floors. Every line of the brief is a thread to pull.
03 — The Cast
One of Them Is the Imposter
Six to nine suspects, each with a face, a role, and something to hide. One of them did it. The rest are only lying about everything else.
04 — Interrogation
Talk to Them. Out Loud.
Question suspects by voice or text. Choose your tone—sympathetic, neutral, aggressive—and watch it land. They answer in their own voice. They remember what you asked an hour ago.
05 — Behaviour
Watch for the Tells
Evasive. Hesitant. Rehearsed. The game reads the room alongside you—flagging the micro-tells and pointing to the question you have not thought to ask yet.
06 — The Case File
Examine Every Clue
Bodies, objects, statements, alibis. Examine each piece, log it, and cross-reference it against the stories you have been told. Your case is built from contradictions, not hunches.
07 — The Scene
Every Room Is a Lead
Walk the floor plan—common rooms, private quarters, restricted wings, the crime scene itself. Who had a key? Who had a reason to be there? Search the space before the clock runs out.
08 — The Verdict
Make the Call
Limited rounds. Limited questions. A handful of accusations and no take-backs. Name the imposter—or press until they confess. Get it wrong, and the room remembers.
Between Rounds
The mystery is alive.
End a round and the imposter goes to work. New evidence surfaces. Old evidence is quietly corrupted. The suspect who trusted you yesterday won't meet your eyes today.
You aren't picking apart a static puzzle. You're chasing something that adapts to every move you make.
"In a room full of liars, the truth is just another suspect."
The Game Has Already Started
Someone in that room knows what you're capable of. Prove them right.
