Tom Clancy's Splinter Cell Chaos Theory includes a single-player campaign that follows gaming icon Sam Fisher on his latest mission to maintain world peace, a two-player co-op campaign that redefines collaborative gaming, and a completely updated versus multiplayer campaign (that first appeared to critical acclaim in last year's Tom Clancy's Splinter Cell Pandora Tomorrow) and offers gamers complete immersion in modern stealth action and endless hours of replayability.
