You could have them shoot a standard kind of round for bullets or arrows, or you could have them shoot the best kind that they have in their inventory for their weapon without depleting it.

That would be essentially infinite ammo, but considering the amount of money to be had in this mod it shouldn't be too big a deal so long as you can't pick anything up afterwords.

Which I think you can pick up arrows normally... but maybe you could disable that somehow? A dummy arrow type that always destroys on impact or something?
