-In Stationeers, Gas is an generalized term for fluid substances, derived from ices or gained by other means, that can be transported and manipulated to change their energetic form (phase) through the combination of pressure and temperature.
+In older versions of Stationeers, Gas was a generalized term for fluid substances, derived from ices or gained by other means, that can be transported and manipulated to change their energetic form (phase) through the combination of pressure and temperature. Newer versions now have gasses and liquids handled completely separately.
 This is opposed to solid resources, processed irreversibly from ores into pure ingots and alloys, used directly for crafting purposes. Gases have a great variety of uses - some are required for creation of livable pressurized environments, while others are toxic and dangerous and meant for controlled industrial processes, or outright waste product with limited utility.

 ==Properties==
-Gases and their liquid analogues are presented in the parametric form - that means that they exist as a property of a given atmosphere' grid cell, interior grid cell of an enclosed room, composite [[pipe]] network, atmospheric device, or portable container. To further understand the behavior of gases within different spaces, check [[Atmosphere]] and [[Pipe]] pages. It is technically possible to convert gases down into their solid state (i.e. a physical item), however that action has no practical use, therefore no dedicated devices exist for doing so.

To further understand the behavior of gases within different spaces, check [[Atmosphere]] and [[Pipe]] pages. It is technically possible to convert gases down into their solid state (i.e. a physical item), however that action has limited practical use, beyond perhaps hand measuring of specific quantities, and no dedicated devices exist for doing so.
 Each different gas have a number of properties, which define its thermodynamic behavior and conditions for phase changes. Leveraging the property values and their differences between gases is an important part of atmospheric management and temperature conditioning required for surviving extreme environments and utilizing advanced technologies:
