DICE, the studio behind the Battlefield franchise and the upcoming Battlefield: Bad Company 2 Vietnam expansion, has just revealed that the upcoming add-on will have a special unlockable map, Operation Hastings.

For those not really familiar with the first person shooter series, Operation Hastings was one of the most popular maps made for 2004's Battlefield: Vietnam.

Now, in tribute to that game, it will be added through the Vietnam expansion to Battlefield: Bad Company 2.

As you can imagine, the map will feature "everything that makes BFBC2 Vietnam amazing: tanks, Jeeps, temples, boats and helicopters all in an environment featuring a distinctive bridge that separates the map into two main areas".

You won't be able to access it right away though, as it will be locked when the add-on is released.

It's up to the players of Battlefield: Bad Company 2 to work in order to reach 69 million team actions, on all of the platforms, including the PC, PlayStation 3 and Xbox 360.

Don't know what qualifies as a team action?

"Well, it's any/all of these: resupply, revive, heal, spot, and repair. Team actions performed both in the main game and the digital expansion count towards the common goal."

Battlefield: Bad Company 2 Vietnam is set to appear on December 18, for the PC, through digital download outlets like Steam or the EA Store, and on December 21, for the PlayStation 3 and Xbox 360, through the PlayStation Store and the Xbox Live Marketplace, respectively.

The expansion will be available for download in exchange for $15, on the PC and the PlayStation 3, and 1200 Microsoft Points, if you want to get it for the Xbox 360.

It will bring, besides the unlockable Operation Hastings, 4 other maps, 6 new vehicles and 15 new weapons, all dating from the time of the Vietnam war.
