About this 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?

New: Safe Mode
Hey everyone, I’ve just added a 'safe mode' for those of you who want to experience all the horror atmosphere without being permanently pressured by the monster. You can activate ‘safe mode’ in the starting room and once activated (indicated by the little red light) it stays active until you manually deactivate it. I would suggest to only activate safe mode if the regular game is too intense for you. {STEAM_CLAN_IMAGE}/45105307/2b6db45251ebd6d74f8fa2dd3ca27ab917c5906a.png V 1.04 Patch Notes: new “safe” game mode fixed missing collisions near the furnace fixed minor visual bugs As always, I’m excited to hear your feedback and if you encounter any issues, please report them here Best, HermannRead full article on Community Announcements (Hermann Hetzer)
