HLSS and wmv quotes with MW2 MP?

Is it possible to use HLSS with MW2 on PC? I think the engine is IW 4.0

I doubt it... from my brief knowledge of Steam games, HLSS refers to a source game = different engine, different game.

Different = not compatible, in my book. All guesswork, btw. Someone more qualified should respond.

Like that.

LOL. I NEED TO DO THAT.
