[@tex] Nah, go for it! Just make it trademarked under Sinnet Inc. :p Just kidding. But is it okay if he have the capability to modify the bullets to have different properties? elemental bullets, armor penetrating, explosive, ect. Or would those be available too? If they are, I have another way his gun could be unique. :p

Going on with the discussion of aerial vehicles, if they are limited, what about ground vehicles? what are they like, and what are the limitations ?
