Well basically you need to edit the default weapon scripts for the default weapons - in these files you can edit rate of fire, recoil, clip size, models used, etc. Basically this lets you create new weapons!

The trouble I'm having is compiling these scripts into my map. For some reason this doesn't seem to do anything for me :(
So for the time being it may well be server side only :/

Hi, quick question:) I've read your zm_saxon thread, and you were saying there that your map will have new custom weapons. Could you please tell me how it is done?
