Well, double shots are as important these days just liek the BXR. I thought that maybe ill post how to do it on our "regular" controls, for all of those interested. You have to hit the fire button twice then press y- or whatever changes your weapons button- twice. But you have to have a secondary weapon first off and second you have to get the timing down. I have been trying it now for two weeks and still i am having problems. I seem to like it when i just br somebody but when it gets close to the end, doing two sets of double shots for the win. Its not easy at all, but it might help you out when br-ing somebody.
