Shadow Echo: AI Mystery

Interrogate. Deduce. Accuse.

Free · Designed for iPad. Not verified for macOS.

AI-powered detective mysteries. Interrogate suspects whose every word could be a lie. An immersive whodunit experience. New cases on the way! 【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? ■ FOR FANS OF Fans of Ace Attorney, Her Story, Return of the Obra Dinn, and classic whodunit stories will feel right at home. If you love dialogue-driven mysteries and cutting-edge AI, this one is for you. ■ LANGUAGES English, Traditional Chinese (Hong Kong), Traditional Chinese (Taiwan) ■ ABOUT AI-GENERATED CONTENT NPC dialogue in this game is generated in real time by a large language model.
