This year's E3 has kicked off and just like every year, first gameplay of Black Ops II was shown during Microsoft's E3 press conference. The mission shown during the press conference was called "Protect P.R.O.T.U.S" and it takes place in downtown Los Angeles, which is under attack. Check it out below.

Don't worry, it doesn't stop there, below you can find a couple of videos that show of the new Strike Force missions.
