## What is Shadow Echo?

【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)
