We now have CO2 as a resource/mechanic in the game. Humans in your station now output CO2, which then builds up as a percentage of your stations air. When this gets to unsafe limits humans will equip their space helmets so as not to suffer damage. Although this gives negative morale and visitors will leave your unhospitable station! However there are several new items to capture and use this resource. Firstly CO2 Scrubbers will capture CO2 from the air in your station and keep levels safe for your crew. You'll need more CO2 scrubbers as you recruit more human crew or have more visitors. CO2 captured will discarded into space, unless you have the new CO2 storage item. CO2 can be traded if you have storage, although more useful is to use it with the new Sabatier Reactor production item. This is a new research item that has to be researched after the advanced refinery in unlocked. The Sabatier reactor takes CO2 and fuel inputs and outputs water. This allows you to experiment with different production chains. As you now have:- Refinery: Ore -> Metal + Water Advanced Refinery: Ore -> Metal + Water + Fuel + Air Electrolyser: Water -> Fuel/Air Sabatier: CO2+Fuel -> Water Quite a few other improvements and fixes as well, here's the full patch notes:-

• New CO2 resource, generated from humans.
• New CO2 scrubber, storage and sabatier reactor items.
• Sabatier reactor new research item.
• CO2 added to trade.
• CO2 indicator added to lifesupport hud and bar chart.
• CO2 boost algae farm production.
• CO2 affect human behaviour - helmet wearing, morale.
• Fix: Air supply figures flickering when near 0 or 100%
• Fix: Missing translations - Engineering/Adv. Refinery.
• Fix: Incorrect resource count in hud when deleting storage and no relocate.
• Fix: Hull status including inconstruction walls.
• Fix: Trade button from ship infowindow not functioning.
