Tom Clancy's Splinter Cell: Chaos Theory is the handheld version of the third entry of the Splinter Cell series. The basic storyline is still the same: The player takes the role of Sam Fisher who needs to save the world once again. This time the evil scheme is about information warfare and tries to drive America, South Korea and China into a war...

Even if the basic premise of every level is similar the actual design is different and more linear than in the console/PC version.

The game also features two multiplayer modes: in Versus the players choose between spy and soldier - the former have to hack computers, the others have to prevent that. In Cooperation two players solve five co-op levels in which one plays a soldier and the other a hacker.
