It's difficult to tell what's different from the pictures, but from seeing it in-game the metallic parts of the weapon seem to be more detailed, while the wooden furniture looks much the same. It's subtle, but I think it looks nicer.
does anyone know where the three piece suit Niko is wearing in this pic came from? i know its not in game, what mod is it from? I really want it. It looks super badass. It looks like the Quantum of Solace suit mod, but I don't think it is.
