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 *** mode you download WPE Pro and get the *** 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.
