Playing as as Sgt.

Players can face the threat alone or with other players in cooperative SpecOps mode. For even more intense combat, take up arms against online foes in enhanced deathmatch warfare on a host of Modern Warfare 2 maps.

Modern Warfare 2 is a first-person tactical shooter and the sixth entry in the popular Call of Duty series. True to its name and following the lead of its predecessor, Call of Duty: Modern Warfare, it places players in modern combat settings, as opposed to the WWII environments of the earlier Call of Duty games. This modern approach brings with it new weapons, action and options. Coupled with a variety of gameplay modes including single player, multiplayer and the co-op Special Ops Mode, it is destined to be one of the most popular games of 2009 and a worthy addition to the Call of Duty series.

Human experience with nuclear, biological, and chemical (NBC) warfare has been limited, especially in comparison to conventional forms of warfare. Our experience with nuclear warfare is confined to a period of less than one week during the end of World War II, when the United States successfully used two nuclear weapons against targets in Japan. The course of biological warfare and modern use of biological weapons are difficult to track owing to the difficulty of differentiating deliberate use from natural outbreaks.
