In 'Hello, Who Dis?', you wake up in a completely unfamiliar city with no recollection of how you got there. The only clue you have is a mysterious phone that belongs to a stranger. As you traverse this strange urban landscape, you receive texts and calls, each leading you deeper into a web of deceptions, conspiracies, and the eccentric lives of the people around you. Your choices influence the characters' interactions and can unlock multiple endings. Stay alert, because not everyone you encounter has your best interests at heart.
