Hi usb,

To get a better explanation you can download the SDK that will show you a lot of what you need to know. As for the weapons that I have made and added, they are selectable by pressing 'Ctrl+Shift+7' to scrol through and the different missiles/rockets are named on the HUD display.
You can also read the attached 'readme' file that I added to each missile download and that will also tell you what the HUD name is for each new missile.
