Splinter Cell Chaos Theory 
You are Sam Fisher, the NSA's most elite black-ops agent. To achieve your mission you will operate undetected, kill at close-range, attack with your combat knife, shoot with the modular SC20K rifle, and use radical suppression techniques such as the inverted neck break. Work alone, or enjoy the thrill of cooperative multiplayer infiltration missions, where teamwork is the ultimate weapon.

Pandora Tomorrow
You have the right to spy, steal, destroy and assassinate, to ensure that American freedoms are protected. If captured, the U.S. government will disavow any knowledge of your existence. You are Sam Fisher. You are a Splinter Cell.
