This is your first look at multiplayer in this November's presumed mega-hit, Call of Duty: Black Ops II. Call of Duty fans, this is why you play, no?
The battles appear to be taking place in the game's near-future of 2025.
We've got some most unusual knife and tomahawk kills.
Some sort of microwave transmitter screwing with the enemy. (Or maybe it's DARPA's Pain Ray?)
Remote-controlled drones. Lots of them.
... And after the title screen at the end, it sure sounds like this match is being shoutcasted.
