I actually don't miss "prone" now, though I did when I first started
playing it after playing COD so much. The reason there is no prone in the game is because it made
snipers invisible, especially is the lush underbrush. With vehicles you
are better off having a partner or two in with you. The more eyes the
better ya know.
I play with a Razor headset and a Sound Blaster X-Fi Titanium Fatal1ty Professional Series. For guns and explosions it's the best sounding fps I've heard yet. And the BF3 is suppose to sound better. They've worked on making it easier to hear footsteps and what direction they are coming from, things like that. They have also added Jets as another vehicle. Should be interesting. I'm not a big vehicle guy though. I play squad rush 99% of the time.
