Today the fourth VIP map pack for Battlefield: Bad Company 2 hit the PS3 and Xbox 360. Its PC release is expected later in the day.

VIP Map Pack 4, like previous BF:BC2 packs, doesn't add new maps. Rather, it unlocks previously unavailable modes for existing maps. Once you've loaded up Map Pack 4, you'll be able to play Atacama Desert on Rush and Port Valdez on Conquest.

Unlike the Onslaught Mode DLC, the VIP map packs are completely free - assuming, of course, you bought a new copy of BF:BC2. The voucher inside the box will give you VIP membership. If you bought the game used, you'll need to purchase the VIP code. Note that this only applies to the PS3 and Xbox 360 versions of the game, though; it's all free for the PC.
