Andrew Sterling is a former British SAS soldier working for MI6, who has been captured in the People's Republic of China and jailed in Chang political prison; MI6 destroyed all files on Sterling to prevent an international incident. He is rescued the night before his execution by an old female acquaintance named Kim and a former fellow SAS soldier Daniel Parish. To repay his debt to Parish for saving his life Andrew agrees to work for his private security agency. Sterling then travels to Egypt to eliminate the leaders of an arms dealing cartel who possess a missile guidance system called Octopus. He completes his mission but at the cost of Kim's life. The antagonist is John Grey (voiced by Tom Baker), who as a young man who enlisted in the RAF to defend Britain at the height of World War II. Horrified by nuclear weapons John Grey formed a secret society, "Greywings" inspired by the heroes of the H. G. Wells novel The Shape of Things to Come. Greywings sought out and destroyed nuclear threats but ultimately came to the conclusion that the only way to abolish nuclear warfare would be to create a nuclear winter leaving the survivors afraid of nuclear warfare. Greywings planned on initiating their plan codenamed Operation: Cold Winter by providing world powers with the Octopus guidance systems. The game uses the Karma Physics engine, allowing for interactivity with items in the game world and for ragdoll effects. Cover can also be improvised by using objects in the environment; for example, the player can flip a table to provide cover or grab a table and block a door. Over 30 weapons are available. Using a small inventory menu, some weapons and tools can be constructed, such as Molotov cocktails and lock picks. The game offers a multiplayer component that supports up to four players offline and eight players online; in the offline mode, human players may be substituted for CPU-controlled. There are a dozen maps and six modes, including deathmatch and king of the hill. Source: Wikipedia, "Cold Winter", available under the CC-BY-SA License.
