In its continued attempt to get you to play military shooters that aren't Call of Duty, publisher EA is building the hype for this winter's Battlefield: Bad Company 2 Vietnam expansion. It costs $15. It has four multiplayer maps. And?

And it has "true war dialogue", according to a press release issued today. That would be: "All-new voiceovers for both American and Vietnamese forces, based on authentic communication from the Vietnam war for maximum immersion."

It also has patrol boats, Russian tanks, Hueys, 15 weapons, 10 Achievements/Trophies and one new trailer that you can see here.

The expansion is set for a Winter release and will tack onto the Xbox 360, PS3 and PC's Battlefield: Bad Company 2, allowing players to continue leveling up with the progress they've started achieving in the base game.

Medal of Honor. Bad Company 2. EA's got a lot of war shooters. You weren't planning on playing some other war first-person-shooter soon, were you?
