Something interesting that I find, is that all of the stock weapons save for the trenchgun use a basic ammunition for that particular weapon. What if the trenchgun used slugs? or the M32 grenade launcher used 40mm buckshot? or even just simply giving the hunting shotgun dragons breath aswell? How about a crossbow with explosive bolts(yes, i know, imaginitive! but yes, it works in other games). I tell you, this would be interesting. So maybe multiple versions of the same gun for different classes?
