Yeah, I slipped away from bf2 when I got my 360, but my 360 bit the dust so Ive been back on bf2 with a vengence
I got the SF expansion at christmas and installed it but only played about 10 times, By installing and playing SF on your account you get additional gun unlocks on your vanilla BF2. SF is ok there are lots of close quarter battles inside buildings/carrier ships etc, and it gets really hectic with tear gas and flash bangs going off all over the place your lucky if you can stay alive for more than 30 secs at a time when a battle for a flag inside a building kicks off it kinda feels like your getting spawn killed only option is to spawn well away. also all the extra action put more stress on the graphics card, I got BF2 running sweet but getting slight pauses on SF. Give it a try you might prefer it
