You have to get better ranks. In battlefield 2, some ranks have unlock available and some don't. You just have to know which ones do.

you don't press any keys.

You have to play on Ranked servers(Multiplayer), and everytime you kill, revive, etc. anyone you get points. Everytime you gain one rank, you can unlock 2 new weapons. You can only unlock 2 weapons when you go one rank higher. So choose carefully!On Battlefield 2, how do you unlock new weapons?
