Splinter Cell: Pandora Tomorrow

Deployed by a top secret wing of the NSA (National Security Agency) known as Third Echelon, Sam Fisher is a lone field operative supported by a remote team. Fisher must defend and assist the U.S. military, both locally and from remote locations, until Suhadi's terror-driven policies can be subverted and the guerrilla faction eradicated. Charged with saving the world, it’s a high stakes game. If he fails, the U.S. will deny any knowledge of his existence.
