it's been a long time since I'm looking for some kind person who has created weapons, because I'm not very good at creating maps, so I was looking for someone, who would donate his weapons to me, or at least make them public ....
I await answers

If you like black ops 1-3 and ghosts weapons.  I have a really site I got mine from.  Dont bother aking for anything here, because you will more than likely not get it.

But the site gives you everything you need (xmodel, sounds, etc ...)?
What is the name of the site?

It supplys all you need.  Each gun is in a seperate rar file, just drag the contents into the game's root and then run converter and convert all.  Then place the files in your mod and call files needed in mod.ff.

Here is the link.

The site's thread should give you additional instructions.
