Endworld: Twin Cities Run

The earth is devastated, left a desolate wasteland of mutant beings and desperate renegades by the final holocaust of World War III. Out of the ashes rose Blade, leader of the brutal fighting force known as the Alpha Triad. Together the Triad must risk sudden death to retrieve the vital serum that would save a handful of survivors from a lethal disease. But first the Triad must fend off hordes of deranged humanoids, a hideously deformed creature that hungered for human flesh, and make their way through a long-dead city ruled by warring factions that let no one survive!
