Bad Company 2 Vietnam trailer is explosive

EA's just delivered this new teaser trailer for upcoming multiplayer expansion pack Battlefield: Bad Company 2 Vietnam.

The DLC, which launches on December 18 for PC and three days later for PS3 and Xbox 360, features four new multiplayer maps based on the Vietnam war.

Costing $14.99 / 1200 MS Points, it was designed to "compete head to head with Call of Duty: Black Ops", EA chief financial officer Eric Brown said last week.
