Shadow Echo: AI Mystery

【Shadow Echo】

One murder. A handful of suspects. Countless lies. You are the only detective who can unravel it.

Shadow Echo is an AI-powered detective mystery game. Every NPC is brought to life by a large language model in real time — they remember what you've asked, react to your tone, crack under pressure, or double down on their lies. No two interrogations are ever the same.

■ GAMEPLAY

◆ Open-Ended Interrogation Question suspects in your own words. No dialogue trees. No multiple choice. Ask the right question and they'll slip up. Push too hard and they'll shut down.

◆ Crime Scene Investigation Explore each location. Tap to examine objects, uncover hidden evidence, and piece together what really happened. Some clues only make sense after a certain conversation.

◆ Name the Killer When you're ready, make your accusation. You must also reconstruct the timeline of events — when did the killer arrive? How did they leave? Miss one beat and an innocent person takes the fall.

◆ Rank Up Every case is scored from F to S based on accuracy, evidence coverage, and timeline reconstruction. Can you solve every mystery at S-rank?
