Hello, I'm currently brainstorming ideas for a mod to expand a little bit on how the game's firearms work in general. One of my main objectives is to integrate the way things work in the mod into the game's lore in a seamless manner. My current interpretation of how the firearms work in the game is that the guns contain a micro 3D printer that produces the ammunition and feeds it into a sort of internal magazine which is then chambered and ready to fire. While I don't want to go into too much detail and over complicate things more than what I'm probably going to anyway, I'm still stuck trying to figure out what kind of propellant the guns could use. My current idea is to use some sort of highly compressed gas that is ignited by a spark produced by the weapon's power source. That is one idea but I'd like some more, any thoughts?
