The Battlefield: Bad Company 2: Vietnam expansion pack is just a few weeks away from being released. Starting on December 21st, players will need to come together and the BC2 community (on all platforms) will have to collectively perform 69 million team actions (revive, spot, heal, resupply and repair) in order to unlock a fifth map called "Operation Hastings." This map was actually first seen in the classic PC game Battlefield: Vietnam. The expansion features all new weapons, vehicles, achievements and trophies, and of course will have five maps to enjoy.
