Ok I'm at the part where the twins are chasing you and you're in the car shooting at them.

OMG! WTF is with this part?? no matter what I shoot, they just drive right up to me and kill me in like 30 seconds. You can barely take any damage before you die. I can hold them back a little I just hold the trigger down and shoot up their car, but eventually they drive and shoot me at point blank. I"ve tried shooting the gunner, shooting the driver, shooting the engine, shooting the tires and nothing works. How the hell are you supposed to get away??
