Within the cut throat gaming community of Combat Arms, there is a term for renting weapons... that term is Jack Rental. Jack is a legend within the CA community, he also will defend CA against any criticism to the point of raging and probably being blue in the face! As long as the Jack Rental can rack up 100 frags a round, and mock his own team because his rented weapons are superior to the casual gamer, Jack is in command! Be warned when you face him or even if you are unlucky enough to be teammates with him.
I would play Combat Arms, but Jack Rental is such a cock sucking prick when you play with him.
