Plot.
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.
It turns out that Grey hired Parish to liquidate the Egyptian arms ring because they stole an Octopus unit which was intended for world superpowers rather than the third world countries its thieves planned on selling it to. Grey soon after betrays his own organization to save the life of his infant granddaughter. Sterling is sent to Greywing's headquarters in the Himalayan mountains where he destroys the facility's power core and escapes in Parish's helicopter. Grey is then seen in the game's last scene on a bench in Prague where his former subordinates murder him.

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

Whilst not the best game of its type it was "definitely worth playing".
