The article is incomplete but since I register I may help building it.
Anyway. Great game. Lots of guns, crazy amount of modifications for the guns. Runs nice. It's free and there are almost no hackers (at the present date and on Euro version).
BTW: I'm thinking of trying BF2 Project Reality. How are the guns on it?
