About the Game

“HEART-LUNG MACHINE is an intense horror game that focuses on delivering an exceptionally immersive VR experience.”

You unsuspectingly venture into an abandoned underground complex and become trapped in darkness. With a dying flashlight, you navigate eerie corridors, searching for items to ensure your survival. As you're forced deeper, you uncover horrific secrets about the facility's past. Worse still, something is stalking you in the dark. Hide!

The threat is real: The game's AI operates autonomously, presenting an unpredictable and relentless challenge. Stay stealthy, or risk drawing its deadly attention.

Experience true-to-life hiding mechanics: Physically crouch behind objects, crawl into shafts, slide under tables, or squeeze into lockers to hide.

Brutal narrative: Set in a mysterious facility designed to deliver relentless suffering. Will you put an end to the torment?
