Battlefield: Bad Company 2 Vietnam is now available for Windows, Xbox 360, and Playstation 3, offering a Vietnam War expansion for DICE's military shooter sequel. The PC version is currently available through the EA Store and Steam, and next week on December 22 it will also become available at select retailers as well as other digital distributors. The Battlefield Blog offers the Battlefield: Bad Company 2 Vietnam Launch Trailer, and here's word on what to expect from the add-on:

In Battlefield: Bad Company 2 Vietnam, gamers will find themselves in an entirely new theatre of war, fighting as either the U.S. Marines or North Vietnamese Army (NVA). The punishing jungles of Vietnam are brought dramatically back to life via the award-winning Frostbite™ engine, where players can take advantage of Battlefield’s classic sandbox environments in five all-new multiplayer maps using powerful air invasions or close-quarter guerrilla tactics.

Battlefield: Bad Company 2 Vietnam takes all of the intensity, action and addictive gameplay of the multi-million selling Battlefield: Bad Company 2 and ups the ante with new weapons, vehicles, achievements and trophies. Featuring five all-new maps playable in four different modes including Conquest, Rush, Squad Deathmatch and Squad Rush, Battlefield: Bad Company 2 Vietnam will continue to deliver exceedingly intense vehicular warfare, destruction and squad play.

The fifth map, Operation Hastings, will be unlocked as part of a worldwide community challenge, where players will work together to reach 69 million team actions on each respective community – Xbox 360® videogame and entertainment system, PlayStation®3 computer entertainment system and PC. The challenge begins on December 22.
