The screenshot above represents the first look anyone has gotten at the upcoming Battlefield 3: End Game expansion. As you can see, it features a motorbike -- a feature previously promised.
There's also a teaser trailer out for the DLC, though it's intended for Premium members only. As such, I'll just say it features plenty more motorbikes where that came from. If you are a Premium member, hit the source to check it out.
End Game launches this coming March.
