I am a soldier. I've served my country for twenty years. But if I'm captured or killed, I know that nobody will come to rescue me. I won't even get a funeral. Because the nation I protect can never admit that I exist. So my death would go unremarked, my bones would go unclaimed. I don't know if that day will come... but I do know that it must not be today. I am invisible. I am relentless. I am Sam Fisher. I am... a Splinter Cell.

Few presidents have ever granted the Fifth Freedom. It's the right to defend our laws, by breaking them. To safeguard secrets, by stealing them. To save lives, by taking them. To do whatever it takes to protect our country. The Fifth Freedom is mine alone. I am Sam Fisher. I am a Splinter Cell.
