The Battlefield Blog offers a new trailer from Battlefield: Bad Company 2 Vietnam, showing off the flame-thrower in action. Word is: "As our playtests rage on here at the DICE office, it's clear how much the flame-thrower gives to this expansion in terms of style and sheer aggressiveness. Check out the trailer above for more fire-based action, and remember to come back next Friday for even more info and screens from Battlefield: Bad Company 2 Vietnam."
