Shadow Echo
Read full descriptionHide full description
【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. All characters and events are fictional. Content safety filters are in place; inappropriate responses can be reported. ■ CONTACT Privacy Policy: https://legal.shadow-echo.workdev.xyz/privacy Terms of Service: https://legal.shadow-echo.workdev.xyz/terms Apple’s Standard License Agreement: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ One case.

深夜,一碗湯,一個真相。 《海龜湯》是一款 AI 深夜推理遊戲。主廚給你一段離奇的故事片段,你只能問「是/不是/無關」的問題,一步步逼近藏在湯底的真相。在這裡,主廚是一位不會累、不劇透、隨時開桌的 AI——你想查多久,他就陪你查多久。 【怎麼玩】 ・向 AI 主廚提問:打字或語音都行,AI 即時判定「是/不是/無關」,陪你把真相一點點翻出來。 ・每晚一碗新湯:官方每日出題,深夜上桌,免費。 ・自己出一道湯:在「後廚」寫下湯面與真相,AI 自動生成插畫、配音與審核,做成一道能分享的作品。 ・揪朋友開一桌:多人包廂輪流提問、搶答真相,看誰先解開。免費,零門檻。 【給誰玩】 喜歡劇本殺、密室、偵探推理、水平思考(lateral thinking)與燒腦解謎的你;睡不著、想找點事情動動腦的深夜時分。 【關於代幣】 既有官方湯、每日新湯、大小提示、多人包廂全部免費。只有「用 AI 生成你自己的一道原創湯」需要消耗代幣(每道 6 代幣),因為它會真的呼叫 AI 生圖與配音。註冊即送一道湯份的代幣,先玩過一次完整體驗再決定。 深夜營業中,這碗湯,替你留著。
