If you need an excuse to play more Battlefield Bad Company 2, the folks at developer Digital Illusions and publisher Electronic Arts are happy to oblige you. Today the developer of the popular modern military shooter have announced that the fourth map pack for the game is now available via free automatic download for PC owners.
