In the multiplayer major Keen moved the airtight / pressurization feature into the new Experimental mode. It's been put in no uncertain terms, on the various streams and even Marek's blog, that stuff in experimental is not likely to be worked on any time soon. He is also saying, and I quote: "It’s still possible that in the future some features could move out of experimental mode if we discover a way to make them viable and performance-friendly.". I'm asking for that to be made a priority for the gameplay major, to actively try to find a solution to this. I'm asking for this to become a primary survival feature. Please help me tell Keen that this is a feature we want as a primary feature, and not something put off to the side. https://useresponse.keenswh.com/spaceengineers/general/topic/save-the-pressurization-feature Thank you! [Add.] We have gotten some slightly encouraging responses to our plea already. Keep the votes coming, it might actually be working!!! Let's turn that "slightly encouraging response" to a definite yes! [Add. 2] We won through. They listened. A huge thank you everyone who voted and made sure they knew this is something we want!
