Once a playground for the world’s wealthy elite, Dubai has fallen victim to a series of cataclysmic sandstorms. The city’s opulent architecture lies half-buried under millions of tons of sand.  Abandoned, the city became a no-man’s-land for refugees and outlaws.

While most people have fled the now-barren wasteland before the sandstorms hit, US Army Colonel John Konrad and his loyal squad remained behind to protect those incapable of escape. Unable to reach anyone in Dubai after the storm hit, the US Army feared Konrad and his team dead until they picked up a weak distress signal and launched a rescue operation.

As Captain Walker, you and your elite Delta Force team infiltrate the treacherous region to bring Konrad home. There, you and your men will face The Line, that razor's edge known only to men who deal in war. It is The Line they cross when death and duty become one and the same. It is the end - of self and sanity - when duty is done and only the line remains.
