To shoot rockets like a machine gun you get Gun Lock (should be in a trainer like Purdic Public) and you lock onto your rocket launcher and switch to your machine gun and just fire away. Also you don't install god mode you download WPE Pro and get the god mode file should be a .flt and then load it in WPE Pro select GunZ and click on the ON button. But it makes you lag really bad in a game with 12+ peoples.
