"We've intercepted a faint signal from deep inside the abandoned city. There may still be survivors. We need you to go in and find out. Your squad is already on site — move out."
Search the site, investigate alongside squad members with… very distinct personalities, and uncover the truth behind the signal.
This is a hands-on puzzle game, not a talk. One run takes about 30 minutes, and you can drop in during the session. Bring your phone — the investigation runs on it. Puzzles are available in both Chinese and English. All interested recruits, report to the city — the squad is waiting.
