In Tom Clancy’s Splinter Cell Chaos Theory, the year is 2008. Citywide blackouts, stock exchange sabotage, electronic hijacking of national defense systems: This is information warfare. To prevent such attacks, operatives must infiltrate hostile territory and aggressively collect critical intelligence, getting closer than ever to enemy soldiers. Through the eight level missions of the single-player campaign — one of which is exclusive to the Nintendo DS — Sam Fisher, the most elite black-ops agent of the National Security Agency, will kill from close range, attack with his combat knife, shoot with the prototype Land Warrior rifle and use radical suppression techniques such as the inverted neck-break to accomplish his duty. The Touch Screen technology allows players to manage the inventory, choose between three visions modes, maneuver the camera and interact with the minigames. The Wireless Communication of the Nintendo DS will be intensely used for the multiplayer modes: Cooperative mode for two players with five levels to explore. Each player can choose between two Shadownet expertises: Assault or Hacker. Versus mode for two to four players with seven maps available. The Versus mode places you in a war of Shadownet spies versus ARGUS mercenaries. While spies try to hack computer devices to steal important information, mercenaries must patrol and guard these stations.
