Apparently there's a way to obtain the special forces guns without buying the expansion pack, its not really much but for the people who don't want to buy it you can at least use the guns without having to pick up other peoples kits.

Does the expansion come with it's own cd key? If it does they could track serial numbers everytime someone goes onto a server? and then maybe shut down your account.

he says you have to login to SF

so, unless you know someone nearby with the game that you can log into, you'll have to buy it

Good thing my dad has a copy Thanks sharp!
