Super easy! Just build a base compartment (like a Multipurpose Room) and slap a Hatch on it. Add a Solar Panel or any power source to your base, and voil脿, oxygen everywhere!

I remember my first attempt! Got stuck in my unpowered base wondering why I couldn't breathe. Trust me, connect a power source and your base will fill with sweet, sweet O2!
