Forum Overview :: Battlefield 3 :: the unlock system just gives unlock points, you can spend them on any unlock

[quote name="the truth"]want a red dot scope for the smg next? just get 1 point and spend it on the red dot (or whatever futury shit sight system). want the engy pilum anti tank rifle? well, that and the wire guided rocket are unlocked for engys BY DEFAULT but you can buy any attachment or upgrade or other alternate weapon just by aquiring an unlock point. also things you can unlock with an unlock point that will be helpful: coop experience boosters. coop naturally will provide xp, but at a reduced rate compared to normal multiplayer. but there should also be a way to improve the coop xp gain if you really just want to play the coop campaign, so you can spend a point on the coop xp boost which permanently increases the xp gained from coop.[/quote]
