HEART-LUNG MACHINE is a VR horror game designed to create an immersive and intense experience. Players find themselves in an abandoned underground complex, where they must navigate dark corridors with a dying flashlight, seeking items to survive. As they venture deeper, they uncover disturbing secrets about the facility’s past, all while avoiding a lurking presence. The game’s AI operates autonomously, offering a dynamic challenge that requires stealth to evade detection. Realistic hiding mechanics let players physically crouch behind objects, crawl into shafts, slide under tables, or hide in lockers.
