Oh right so motorbikes cut it but Camaros don't?
Speedy off-road dirt bikes, those mechanised horses, are coming to Battlefield 3 inside the fifth mini-expansion, End Game.
Also inside: four new maps tailor-made for high-speed off-road warfare, and the return of Capture the Flag.
On top of that, lightweight AA vehicles and a new trooper dropship that plops out troops all over the place.
That's all the info there is at the moment.
End Game is the fifth and I believe last of the planned Battlefield 3 DLC add-ons. Back to Karkand, Close Quarters, Armored Kill and Aftermath came before it. Alone they cost Ł12, but you can buy them all plus get headstart access with Battlefield Premium, which costs Ł40.
