A fifth map for the imminent Battlefield: Bad Company 2 Vietnam expansion has been confirmed by DICE.

Once players in the Xbox 360, PC and PS3 community each collectively amass 69 million team actions, the Operation Hastings map, first made famous in the PC game Battlefield: Vietnam, will be unlocked.

A team action is 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 will be available on December 18 on PC at the EA Store and Steam, and December 21 on Xbox LIVE and PlayStation Network.

Five maps set in a new environment with all-new assets (weapons and vehicles) for £10 is great value by today's standards.

Microsoft asks gamers to pay 800 MS Points for three maps, while Activision charged £10 for Modern Warfare 2 maps, but sets included two older maps brought over from Modern Warfare - Operation Hastings has been completely remade for the new DLC.

The maps in Battlefield are also much larger than those found in Call of Duty. For more on the new content check out our hands-on preview.
