In 2026, on a drizzly afternoon, Xiaoqin’s niece opened a yellowed notebook in a lab at the Graduate Institute of Applied Science and Technology at National Taiwan University of Science and Technology. All that remained in the letter was the LINE contact information for Aunt Lin Shufen—her aunt’s college friend—and a mystery dating back to 1994. Players will need to gather clues and piece together the truth within a limited time to uncover the secret behind the “sudden disappearance” from all those years ago. The event also incorporates AI-driven character interactions to solve puzzles; participants can obtain hints and key clues by conversing with the AI.

The latest masterpiece from the NTUST MEG team, "Gongguan 1994: Understanding Across Generations", is an on-site mystery-solving game that combines interactions with AI NPCs and a precise GPS positioning system with real-world settings to create an immersive puzzle-solving experience. In the game, you’ll play the role of Aunt Xiaoqin’s niece. The only person who knows the truth from back then—Aunt Shufen—is in the game; talk to her to get hints and uncover clues to solve the mystery!!
