^I actually haven't played any of the other battlefield games. I'm stuck without three of the find all five, I think.. the assault rifle, shotgun, and sniper. Can't get the gamer-tag link to recognize me. Keeps saying try again later, or error (but when I input my old GT that I canceled, it registers- not that that solves anything). Also, I have no chance of getting the chinese sniper rifle, because that was a preorder code, and gamestop didn't come through- perhaps EA didn't supply.
The sniper rifle I love to use is
VSS "Vintores"--- basically fully automatic, 12 round clip. Single shot gives more accuracy of course (pulsing), but if a guy is standing still for a second and one headshot won't do (sometimes it won't kill a guy if you're not perfect), just hold the trigger down and they're down. Rapage. I end up shooting full clips at one guy to take him down, or firing into clusters of guys as they run, usually. My accuracy is probably the worst on my friends list because of this, and firing at helicopters with support.
VSS came with the Gold Edition.. which I feel a little-kind-of stupid for buying, because I'll be at level 25 (when you would normally receive it) in the next two-three days, and would've got it anyway. The SVU is similar enough, just not as stable (but it's supposedly more accurate and has higher damage).
