Xbox 360 owners worldwide and PlayStation 3 owners in North America will be able to buy the add-on Tuesday, June 22, while European PS3 owners must wait until June 23.
In addition, a variety of "Kit Shortcuts" will be available for purchase beginning June 16 on Xbox 360 and European PlayStation 3s--North American PS3s getting them June 22.
These Kit Shortcuts are "for those players who don't have time to spend levelling up to unlock all the kit specific items but still want to be competitive with those who have unlocked everything," the companies explained in an accompanying blog post.
"The Kit Shortcuts will give you the unlocks available for kit each kit while still allowing you to progress through the ranking system as normal and will be available for 560 MS Points/$6.99 individually or if you want the whole bundle of kit shortcuts including the 7 available vehicle unlocks, 1600 MS Points on Xbox Live and $19.99/17.99€."
As for Battlefield: Bad Company 2 PC, DICE has previously said that "We aren't ruling out Onslaught on PC but at this time we are researching how to bring it to PC without affecting players who don't have Onslaught or their own server to run it on. "
Oh god Electronic Arts, why are you doing this? Why???
I'd blame Microsoft for not letting any content go free over their gaming platform, but we all know that EA's a bunch of money grubbers too.
