What is Cyan Heart?

This single-player sci-fi adventure follows a girl into an abandoned facility to retrieve an object that might halt a spreading, matter-altering energy. Her camera limits your view of the route ahead; you solve puzzles, avoid or exploit hazards, and point the camera at objects to examine them or access machinery.
