In 'Echoes of the Unseen', you play as a paranormal investigator trapped in a haunted mansion during a lightning storm. The catch? You're equipped with only a voice-activated AI assistant that responds to your commands to navigate through the dark corridors and uncover the secrets of the house. As you explore, you discover echoes of voices from the past and manipulate them to solve puzzles and unravel the tragic story of the mansion's former residents. With every door you open, the sinister, unfinished business of the long-gone inhabitants surfaces, leading to a dramatic climax where the walls themselves may hold the key to your survival.
