I am really enjoying it, been playing since the 18th and it's a blast. I think i kind of prefer it to BC2. There is a lot more happening, in a good way. Those crazy intense moments that you got in BC2 once in a while is constant in Vietnam, it's great fun. Although you do find you get naded a lot, especially on some maps. There is one map which in rush mode is ridiculous, two choke points literally 15 meters away from each other and it's just horrific. But kinda funny, too.
But yeah, less sniping. Still there, but less so.
One thing is annoying me though, i don't know if it's a bug, glitch, or on purpose but... EVERYTIME I JUMP OUT A ******* DAMAGED/CRASHING HELICOPTER I GET -10 POINTS FOR SUICIDE, AND IF I'M THE PILOT I GET A LOAD OF TEAMKILLS WHEN EVERYONE JUMPS OUT. AND ITS REALLY REALLY **** *** ANNOYING.
Sorry about that, but it ****es me off to an extreme level.
