Heya dragoon. If you have a hud you built the only thing you need to do is go up to the top of your FPSC x10 interface where is says "file" click it and go to "build game" there it will open a small menu. Click "level settings" and click the edit button right next to the "Global script" There you can scroll down and change the Lives, air, health. Ect.. Hope this helped. Oh FPSC only comes with its default hud. You need to buy or build your own for customs.
