Which helicopter has weapons?

[Klonie Gun]

I don't know which helicopter fires weapons. *scratches head* I'll assume the Police Maverick.

 

[Spock]

Sea Sparrow, and the Hunter

Hunter, rockets, machine gun.

The Sea Sparrow has a minigun with auto-aim.

The Hunter has twin rocket launchers and a minigun with auto-aim.

To use the minigun, press R1. To use the rockets press O (I'm assuming your playing the PS2 Version?). Also, to get the Sea Sparrow you need to collect 80 packages and it'll spawn behind Diaz's Mansion. To get the Hunter you need to either beat "Keep Your Friends Close" or collect all 100 packes and it'll spawn at the Air Base. Beat Keep Your Friends Close and collect all 100 packages and it'll spawn at the helipad in Ocean Beach.

You can do "drive bys" if you use the last camera view (the one that starts on the side of the vehicle then switches to stationary views) and of course you need a sub machine gun!
