The aim of this modification is to tweak some of the weapons' characteristics so they behave in a more realistic manner in-game. It is not an attempt to make every weapon as realistic as possible no matter what, because Grand Theft Auto IV isn't capable of being (nor is it meant to be) a completely realistic simulation of ballistics; this is merely an effort to change the things that don't make much sense so they make more sense, while hopefully maintaining game balance, with the end goal being to make the weapons more satisfying to use without getting ridiculous. Important changes include extended effective range for most weapons and tweaked accuracy, damage and magazine capacity for some others.This mod is designed for a keyboard and mouse control setup. Using it with a console controller setup may result in unexpected results due to the different way aiming and targeting is handled.
