In 'Echoes of Hello', you are Max Hart, a cynical private investigator in a world where nobody remembers their past. One day, you receive an anonymous message simply saying 'Hello.' This single greeting spirals into a complex web of conspiracy involving amnesia-inducing social experiments and underground cults seeking to control memories. As you navigate through richly developed characters and their forgotten lives, each conversation uncovers more fragments of the truth, where choices lead to different revelations and outcomes. Can you piece together who said 'hello' and unveil the hidden agendas before your own memories are erased?
