This is a work in progress, but I've created a couple of weapon trainers in the same style as my 110k Challenge XP Trainer. They are separate trainers for now, but I will probably combine them into one.
I haven't got all of the features added yet, but I'm getting there. I'm waiting for the next game update before I release this so I don't have to re-code the whole thing 3 weeks from now. I want to completely test it to make sure there are absolutely no errors in it, such as the infamous headshots or kills bug.
For now I'm not sure if I want the functions to unlock every camouflage, or just the gold, so you can get diamond on every weapon. I'm also going to have a function to max out each weapon XP. You can prestige the weapon yourself so there won't be any weapon prestige bugs either.
