I mean, I know Plasma is made by superheating Gas or doing something to it with an elctromagnetic field that involves the electrons.

So I ASSUME as long as we fight in an Oxygen it would have essentially infinite ammo. The problem being the battery life in the weapon. I assume taking a plasma weapon keyed (set up? primed? made for Oxygen?) for Oxygen to another atmosphere (methane for example) would have bad results, until the weapon is modified to fire change that gas into plasma. 

Or using it in a airless or non oxygen environment would involve needing a battery and oxygen ammo. Or something.

I'm just assuming the battery dies eventually, and that's after 60 shots.
