Tom Clancy's Splinter Cell: Chaos Theory

Set in the not too distant future, Japan creates the Information Self-Defense Force (I-SDF). The creation of this force is seen as a violation of international law and Japan's constitution, and it causes tensions to rise between Japan, China, and North Korea. In time, North Korea and China set up shipping blockades around Japan, and Japan calls on the United States for help, citing article nine of the Postwar Constitution. Throughout this time, Japan uncovers more and more information that the infamous Black Gold Day was caused by intentional information warfare attacks. As the U.S. prepares to launch the USS Clarence E. Walsh, Third Echelon sends the famous Sam Fisher on a mission that appears to be unrelated to the incident, but which may end up being the most important element of it all.

In Splinter Cell: Chaos Theory, players take on the role of field operative Sam Fisher for a third outing. Fisher has some new moves this time around, and he also has a new weapon always at his disposal; a combat knife. Utilizing the knife, Sam can either kill his enemies, or simply knock them out. At the end of each mission, the player is given an overview of how they did. The more people that the player spares, the better the success score.
