Year 2030. The world at war. You are again in the call of duty. Europe and Russia have joined forces as the new Empire of Eurasia against the United States and South America, now known as the United Continents of America, or UCA, their former allies. The entire continents of Africa and South Asia, including China, are an apocalyptic hell melted down by nuclear weapons. Humanity has done it again. After three years of endless conflict over the remaining oil wells, all Eurasia refineries are concentrated on the Russian city of Volgograd, the frontline city, also known as Stalingrad. UCA, having overestimated their oil reserves, are desperated for resources and have sent all their military forces and commandos to this city and obliterated all resistance to achieve control over the remaining oil in the world. 90 years after the bloodiest battle of history, the Battle of Stalingrad is set to begin again!
