From the official site:
What if the Soviet Union hadn’t collapsed and instead made a decisive advance into Europe? NATO forces clash with the Red Army and a second front is opened up as the Soviets launch an attack on the continental United States. You will find yourself taking on the role of a commander in the epic conflict, controlling the most powerful and technologically advanced military hardware of the time. This is WORLD IN CONFLICT®. The unique design and universal appeal is what led global media to make WORLD IN CONFLICT® the most critically acclaimed strategy game of 2007. The game swept the «Best Strategy» awards during E3 2007, claimed countless «Editor’s Choice» commendations from the world’s top reviewers, and was the clear choice as «Best Strategy Game of 2007» during the end of year awards season.
