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.
This is the mod that keeps me playing Max Payne 2. I prefer this one over Payne Evolution. It's got a ton of great features such as fabulous visual effects that amp up the gunfights considerably (in fact the feeling is greater than in any game I've played, even recent ones), there are gibs, dismembered bodies, you can slit throats with the knife, there are extra campaigns included with it, etc.
