Battlefield: Bad Company 2‘s Vietnam multiplayer expansion has been said to come with four brand new maps. That’s not exactly true, turns out. There will be a fifth, Operation Hastings, though it won’t be available with the others at launch.
The map will be unlocked through a community challenge, not unlike the approach used for Battlefield 1943 last year. Nothing complicated; all players have to do is show they’re a team player and perform 69 million team actions (resupply, revive, heal, spot, and repair) in either Vietnam or the main game, and the new map will be available in no time.
