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 was 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.

The game received "average" reviews according to the review aggregation website Metacritic.

It was one of the five games nominated by GameSpot for the title of Best Story of 2005, with a comment: "A poignant, well-told story penned by Warren Ellis helps make Cold Winter a more engaging experience than your average first-person shooter." The website considered the game to be sonically and graphically average, but an enjoyable straightforward shooter with a decent online mode. Whilst not the best game of its type it was "definitely worth playing".
