So the point of this game is to make a more realistic type of zombie survival game right? Why not make SD ammo regular ammo, for instance, the M9 SD weapon can only use SD ammo right now, but In my opinion should be changed to any type of M9 ammo. I thought it was weird that silenced guns had their own type of ammo seeing as how in real life there is no such thing. Just pointing it out there because after I usually find a silenced weapon with ammo all around it, it becomes obsolete once I use up all the ammo seeing as I cant find anymore. Turns finding a rare gun useless :(
