In 'Hello, Who's There?', players take on the role of Avery, a disgraced journalist who receives an anonymous tip about a long-forgotten series of disappearances linked to a strange phone app that allows users to communicate with the dead. As she delves into the dark web of unsolved cases, Avery discovers that various deceased souls have messages that could either lead her to the truth or drive her mad. The interactive text-based game challenges players to make choices that affect their perception of reality and who to trust among the living and the dead, creating a gripping narrative full of suspense and moral dilemmas.
