hey, how can I switch between the machine gun and rockets in my buggy while driving? Or am I stuck with one or the other while driving?

I switch it with mouse wheel.

I believe buggies can only have 1 weapon type at a time. You can switch them out in your garage. Cuprino can switch with the mouse wheel on pc. Not sure what it is on 360/ps3

yeah, im on 360....dnt have the cuprino yet so I'll see, thanks...

yea cuprino is the one where you can change weaapon/ammo type an its either l1 on ps3 or lb id assume on xbox either way its one of the top left or right bumper button.

On the PC i can change the weapon at Buggy, Cuprion and other cars, but not on the Monarch.
