We just got a fresh batch of screenshots for the four player co-op DLC coming to Battlefield: Bad Company 2 called Onslaught. The mode, announced last week, has players competing on various maps to complete objectives against enemy AI. Yeah we know, that's called co-op.
The half dozen screens go along nicely with the already released teaser video. The content's release date and pricing haven't been announced yet, but expect it sometime this summer on the Xbox 360 and PlayStation 3.
