Tom Clancy's Splinter Cell is a series of award-winning stealth video games, the first of which was released in 2002, and their tie-in novels. The protagonist, Sam Fisher, is a highly-trained agent of a fictional black-ops sub-division within the NSA, dubbed "Third Echelon". The player guides Fisher, who usually has the iconic trifocal goggles at his disposal, to overcome his adversaries in levels based on Unreal engines that were extended to emphasise light and darkness as gameplay elements. All the console and PC games in the series were critically acclaimed, and the series is commercially successful.
Tom Clancy's Splinter Cell was developed in 2 years, after which it was published and released by Ubisoft for the Xbox, PlayStation 2, Nintendo GameCube, Windows, and Mac OS X in North America on November 19, 2002. It uses an Unreal Engine 2 that was modified to allow the light-and-dark based gameplay. An HD remastered edition of the game was released on the PlayStation Network in late 2010. To date the game has sold over 3 million copies and won IGN's Best of 2002: Xbox Game of The Year.
