Kotaku - The record, they tell me, is level 28. We're nowhere close to that when death comes quickly to both of us.
That's the way you die in Modern Warfare 3's Spec Ops Survival Mode: In pairs.
Death can come to the two players one at a time, but typically it's sudden and bunched up. At least that's my experience every time I've played the ever-escalating, increasingly difficult cooperative mode of the soon-to-be released Call of Duty.
