In 'Hello, Unknown', you play as an amateur detective who wakes up in a bustling city with no memory of how you arrived. Your only clue is a mysterious text message that reads 'I know who you are, come find me.' As you unravel the city’s secrets, you interact with eclectic characters, solve intricate puzzles, and navigate moral dilemmas. Each choice you make shapes your identity and relationships, while uncovering hidden truths about your past, the nature of trust, and the line between friend and foe. With an ever-ticking clock, you must piece together your identity and solve the mystery before someone—or something—erases you completely.
