Ok, Burn, you can move and fire as your main action, and the other shot at a Coppertop is a Very Fast action and so happens pretty much at the same time...
You roll -3 and plus 3, for 12 and 18. You needed a 9 to hit, so that first hit is at +3, +5 for three bullets from a Deagle, +7 due to your Coppertop... oooh...
The two cops are blown away.
The guy has finishes his cartwheel. Now, he throws his current gun up into the air, arcing to the left. He then drops and rolls under the next car as the cops fire again. He fires six bursts from the gun, two each at three cops, blowing two away. He then fires again, firing four bursts, two each at two, blowing away another two. He discards the gun as he rolls
Finished rolling under the car, he jumps to his feet, catches the gun he orginally threw, and fires another six bursts at three targets, dropping all 3.
Three attacks on Coppertops in ine action, Burn... guess what this guy has? You are almost in love...
Shit! You are being fired at! Three bullets coming from your left...
