In 'Hello, Who Dis?', players step into the role of a struggling detective in a retro-futuristic city where messages are more than just a medium — they hold the keys to solving crimes. A mysterious app, 'Who Dis?', allows you to receive anonymous messages that could lead to vital clues or dangerous traps. Engage in witty dialogues, decode cryptic texts, and piece together a conspiracy that ties together the city's elite, the criminal underworld, and your own past. Each choice affects the storyline, leading to multiple endings as you try to uncover not only the mystery but also the identity of the enigmatic sender.
