Some maps have this in them. they look like little propane tanks. What are they for??
And why do they only contain a millimetre of nitrogen?
Perhaps he is referring to megaLitres?
That'd be 'ML'. I'm pretty sure the game says 'mL'.
And why do they only contain a millimetre of nitrogen?
Well if you want to get into specifics mL would be milliliter NOT millimetre
These are fuel conisters from the old Killing Floor 2.5, they fueled up the flame thrower which was the new weapon wen KF 2.5 came out. Some of these maps were ports from KF 2.5 or previous versions and weren't replaced with the new KFAmmoPickups.
Just map props as far as I'm aware. I think they may even date back to KF 2.0, seem to recall seeing the same type laying around WestLondon. Could be wrong though.
