Tom Clancy's Splinter Cell: Chaos Theory

Tom Clancy's Splinter Cell: Chaos Theory is a stealth game developed by Ubisoft and released across all sixth-generation video game platforms in March 2005. Though originally slated for release in the fall of 2004, it was delayed until the following spring when it came out for the Xbox, PlayStation 2, GameCube and Microsoft Windows. Handheld versions for the Nintendo DS, Mobile phone and N-Gage were also released. A Game Boy Advance port was planned, but later cancelled.

Chaos Theory is the third game in the Splinter Cell series endorsed by novelist Tom Clancy. As with previous entries in the franchise, Chaos Theory follows the activities of Sam Fisher, an agent working for a covert-ops branch within the NSA called "Third Echelon". The game has a significantly darker tone than its predecessors, featuring more combat and the option for Fisher to kill people he interrogates as opposed to simply knocking them out. As a result, it was the first Splinter Cell game to receive an M-rating by the ESRB, an assessment which has since been applied to all subsequent releases in the series. Actor Michael Ironside reprised his role as Fisher, while Don Jordan returned from the original game to voice Third Echelon director Irving Lambert, having been replaced by Dennis Haysbert in Tom Clancy's Splinter Cell: Pandora Tomorrow.

Chaos Theory was an instant commercial success, selling 2.5 million units across all platforms within a month of its release.[2] The Xbox and PC versions of the game received near-universal acclaim from critics and fans alike;[3][4] the GameCube and PlayStation 2 iterations were also released to generally positive reviews.[5][6] Official Xbox Magazine named it the Xbox "Game of the Year" (2005) for its strong gameplay and lifelike graphics. A remastered HD edition was bundled with the first two games of the series as part of the Splinter Cell Trilogy for the PlayStation 3, released on December 20, 2010.[7][8] Another port titled Tom Clancy's Splinter Cell 3D was released for the Nintendo 3DS on March 25, 2011.
