In 'Echoes in the Abyss', players assume the role of Mara, a sound engineer known for her uncanny ability to isolate the faintest whispers in recordings. When she receives a mysterious old tape labeled 'hellooo,-whos-there', she finds herself drawn into an otherworldly dimension that distorts realities through sound. The deeper she delves, the more she realizes that the echoes of lost souls entwine with her own fears and guilt. Players must navigate through chilling narratives by making choices based on sound clues, unlocking dark secrets and confronting their past while the echoes threaten to consume them.
