But their op goes dangerously wrong from the start, with their team scattered to hell and back, and their target site a dry hole. Now they must fight their way on foot through a city of 3 million ravening dead guys, in search of an underground bunker that might hold the Last Man on Earth. But these undead will not be like any Zulus they have ever fought before - and they surround their new target in a writhing ring of death 30 feet high on all sides...
