AA and AT stuff will stay, just not the mounted machine guns. Since mounted machine guns weren't too useful in BC2, and now we're getting bi pods it makes them even more useless.
Mounted Grenade launchers were highly effective. Now, unless they're going to make a handheld grenade machinegun or something, I insist that they keep atleast the Mounted GL's.
do i gotta pay to get into the beta?
No, Beta is free and open to everyone.
Also, I have a question; will Battlefield 3 inherit the humor of Bad Company 2, or will it be a little more serious?
