A few days ago Electronic Arts announced a new game mode for Battlefield: Bad Company 2; a co-operative ‘Onslaught’ mode. Even more recently, the publisher has released a teaser video to give fans an idea of what to expect.

To celebrate over 5 million sales of the popular tactical first-person shooter, the game’s developer, DICE, announced that the Onslaught mode would soon be available to download for those holding a VIP Pass.
