A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

Hey everyone, This small patch brings over a couple of improvements from the recently released Quest version of the game. V 1.08 Patch Notes: Improved hiding spots in the first level Reworked crank wheel handling If you have any feedback, let me know!
Hey everyone, Here's another update to enhance the overall gameplay experience :) V 1.07 Patch notes: Added subtle sound effects Adjusted placement of certain objects Tweaked some timings based on your playthroughs Reduced unnecessarily high poly counts to further improve performance on low-end machines Best, Hermann
Hey guys, a brand-new demo is now available on Steam, featuring numerous improvements from the main game over the past few weeks. The main game itself gets the 'Ironman' achievement with patch V1.06, along with some minor improvements and bug fixes. You can unlock this rare achievement by starting a new game and completing it without dying, reloading, or using 'Safe Mode.' By the way, if you've already played the game, I'd love to hear about your experience! When you have a moment, please consider leaving a short and honest review. As always, if you encounter any bugs, let me know! Best, Herma
Hey guys, this is just a small code update in preparation for future updates. Best, Hermann
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 e
Hey everyone, Quick update based on your playthroughs: Fixed some collision issues at a hiding spot near the generator. Experimental: Removed the locker from the kitchen in the second level as it seems to distract. Looking forward to your feedback as always!
Hey guys, I've just added an input swap option to make things more comfortable for left-handed players. You’ll find the button to activate left-handed mode right in the physical menu in the starting room, just as usual. This update also brings a few minor visual improvements and performance tweaks. V 1.02 Patch Notes: Left-handed mode / input swap option added Fixed LOD issues (no more pop-ins!) General performance enhancements Updated credits If you run into any bugs or issues, please share them here: https://steamcommunity.com/app/3103480/discussions/1/4632609289965463733/ And as always, I’m
Hey everyone, quick hotfix: Fixed an issue where menu settings wouldn’t load in certain cases. If you encounter any issues, please report them here
Hey everyone, it's finally time to venture deep into the bunker and discover what’s lurking in the dark! Heart-Lung Machine has just launched, and I can't wait to hear about your experiences. There’s a launch discount, so grab it while it lasts! So, the game is out - what’s next? There’s more to come, with new features aimed at enhancing gameplay and expanding the experience. But first, I’m here to tackle any bugs you might find. If you run into any issues, post them here, and I'll look into it asap. Wishing you all a pleasantly horrifying experience! Best, Hermann
I’m excited to announce that Heart-Lung Machine will officially release on November 11, 2024! A massive thank you to all the dedicated playtesters who helped shape it into the experience it is today. I’ll be patching heavily over the weekend to address recent beta feedback, making sure everything’s ready for Monday. In the meantime, check out the new trailer to see what you’re in for: Hope to see you here on release day! Best, Hermann
