Locus Sono is a first-person audio puzzle game, where listening and exploration are the key forms of interaction. The game demonstrates a simple audio mechanic that involves locating sonic “sweet spots” in an otherwise silent soundscape. The game progresses as you unlock portals to new spaces for listening. Each level is a kind of composition that is explored and mixed through locomotion. There are many sounds to explore, including secret ones, and the pathway through each level eventually leads to a mysterious audio theatre.
