Shotgun, snipers and explosives are all I use, with the occaisional tomahawk. I started going over 2 regularly with a couple weapons so it might improve, I don't care. That matches where everything just works are insane.
Get it right, do it nice. If you make a mistake, you're gonna pay for it twice. If you need it... got to have it. Get yourself a shotgun and bring it back home
