Splinter Cell is a stealth-action game that puts you in the roll of Sam Fisher, who happens to be an ex-US Navy SEAL as well as an ex-CIA agent. As y­ou find out in the original title, Sam now works for sub-agency of the NSA known as "Third Echelon". The task of "Third Echelon" is to do whatever it takes in order to protect the county, this task is known as the "Fifth Freedom." And of course, should Sam ever become captured or killed, all knowledge of his existence will be denied.
