The most notable thing about this video for Battlefield 4's Second Assault DLC is just how good DICE are at saying "Levolution" without openly weeping. That must have taken some serious media training.

Second Assault currently has no PC release date. It will launch as a timed exclusive for the Xblock One on the 22nd November.
