Oxygen Tanks are a necessity when exploring the moon or any other planet with insufficient oxygen levels. There are three different types: Light (Green), Medium (Orange), and Heavy (Red). These store oxygen and allow you to breath while in hostile environments. Oxygen tanks are a component of theEVA Gear . Oxygen Tanks do not work without the assistance of Oxygen Gear and an Oxygen Mask .
Once crafted (see below) the Oxygen Tank must be placed in the appropriate space which is just right of the person in the inventory. Once two of any size Oxygen tanks, an Oxygen Mask, and Oxygen Gear are placed in their appropriate slots the EVA suit is ready for use. An Oxygen Tank can be refilled using an Oxygen Compressor.
