You are a Marine Sharpshooter, member of the elite Counter Terror Unit, a covert American military force waging a silent war against terror across the globe. Dropped behind enemy lines, you have uncovered a terrorist plan to construct a nuclear weapon and detonate it on American soil. You must follow the plot from the desserts of Afghanistan through the Russian winter and into the jungles of a small south Pacific island. Armed with an arsenal of authentic sniper weaponry, your only assistance is provided by your observer, your eyes, ears and close quarters machine gun. Make every shot count, your country is depending on it.
