The purpose of the mod is to make Max Payne 2 more realistic and tactical, but at the same time to give a dramatic and cinematographic feel to the shootouts.
Here's a quick demonstration video about the new Gibbed Death.
When you directly hit an enemy with the Grenade Launcher or when an enemy steps above a Grenade when it explodes (or he is less than one meter distant) he will be gibbed with two possible deaths: one makes him disappear and leaves only a couple of bone pieces and chunks, brain, colon, eye, hand, limb, muscle and upper torso. And the other death makes him disappear and leaves only a couple of bone pieces and chunks, head, brainpiece, guts, hand, hart, kidney, ribs and lower torso.
Both the deaths includes particle effects, flesh pieces, burning chunks, gore decals, flies sound ecc, and do not overwrites the usual explosion death (that will happen when not in theese two specific situations).
