Cross-Examination: How We Built an AI-Powered Interrogation Game
Designing a game loop where players interrogate suspects and AI drives the responses in real time.
At Uplay.io, we don’t just build games — we build systems. Our newest experience is an AI-powered interrogation game where you play as a detective, extracting truth from suspects in a case that constantly shifts based on what you ask.
Traditional detective games use dialogue trees. This game generates responses dynamically based on trust, pressure, personality, and evidence — so interrogations feel less scripted and more human.
How the AI Works in the Game
Most mystery games are built on branching paths: choose A → get response B. We wanted something more alive. So instead, suspects respond in real time based on:
- Personality (defensive, cooperative, charming, evasive, etc.)
- Pressure (how cornered they feel)
- Trust (how safe they feel talking to you)
- Evidence (what you know and what you reveal)
- Prior claims (what they already said earlier)
The system also extracts claims from responses so you can compare timelines and spot contradictions.
The Core Gameplay Loop
1) Interview suspects
You have limited time or limited questions. Your tone matters — push too hard and they shut down; play too soft and they control the narrative.
2) Capture claims
Every answer contains claims like “I left at 9:30,” or “I never went near the stairwell.” The game logs these so you can track what changes and what doesn’t.
3) Use evidence strategically
Evidence arrives as the case unfolds — access logs, timestamps, security details. Don’t reveal everything at once. Let suspects commit to a story before you confront them.
4) Break contradictions
Your win condition is not “ask every question.” It’s identifying the crack in the narrative — a time that doesn’t fit, an access claim that can’t be true, a story that shifts under pressure.
How to Play Like a Pro
- Lock down time first. Timelines are the easiest place for lies to collapse.
- Build trust early. The more they talk, the more they expose.
- Hold evidence. Leverage is stronger after they commit to a lie.
- Watch the tone shift. Shorter answers and defensiveness usually mean you’re close.
