Ok, first off i'm a noob so don't flame me THAT much lol. Anyway, I searched the forums, they said use a chunk adder program to add that weapon to a map. I have chunk adder program, but since i'm noob i have NO IDEA how to use it, and I don't see a place to set the spawn points or anything, I want to keep all the weapons i have on the map plus another one, but I don't know how. Here is the pic of the program i'm using
Try to remember I'm a noob, so step by step would be good for me, LOL
