The Vietnam expansion for Battlefield: Bad Company 2 (all versions) was announced at E3, and then it seemed to disappear for a while there. It's back, thankfully, with a new trailer and a few screenshots.
The add-on still has no price, but when it becomes available this winter, we'll be getting a significant chunk of new material. Four maps (playable across all multiplayer modes), six vehicles, 15 weapons, 10 Trophies/Achievements, new in-game dialogue, and 49 songs.
Yes, EA DICE got "Fortunate Son." Scratch that off your checklist.
