This video offers another look at the Onslaught DLC for Call of Duty: Ghosts, focusing on the new extinction mission this will offer when its released for Xbox LIVE next week and later for other systems (presumably about a month). Here's the story: "At a remote facility in the Alaskan wilderness, the shadowy Nightfall Program has been researching the origins of the "Alien" threat. When the scientists lose control, a small team of elite soldiers must retrieve the intel, exterminate hordes of hostile creatures, and survive a three-story tall terror unlike anything they've faced before. Get ready for Episode 1: Nightfall, the first installment in Extinction's four-part episodic narrative!"
