The scope of this mods is to replace all ballistic weapons with new high poly models that have full reload animations etc. and also to add new ones. The mod uses CaliberX so all guns use the right type of ammo. Also all the new weapons are integrated in the leveled list and vendors. I tried to replace the vanilla models with the same type of weapon but it was not possible in every case so I had to improvise a bit.
This extensive replacer mod is pure sexiness, I haven't found any other mod with an amount of new content rivaling it other than full overhauls. The author of this mod has done tons of work, evident by all the mods for the guns, let alone the guns themselves. If I had excess cash, I'd give him some, and I don't ever donate things.
