CTU: Marine Sharpshooter

You are a marine sharpshooter and 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 deserts 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.
