About the game
Heart-Lung Machine unfolds inside a long-abandoned underground complex, where players have to get down and crawl, using stealth to stay alive against a monster that never lets up. Along the way, unsettling secrets tied to the facility come to light, all framed as an intense VR horror experience. The title was created by Hermann Hetzer, published by Schreckstoff, and released in 2024.
