i need a step by step guide for this shi*! how the hell do i set up secondary fire so only 1 gun fires!!!!

Just remember: White=Off Red=On. Beyond that, group 1 is when you press the 3 key, like you used to do for rockets, group 2 is when you press the 4 key, like you used to do for homers, group 3 is when you press the 5 key, like you used to do for swarmies, I think, 3 is 5 etc.

that helps a lot. thx

np :)
