Gambit

An American billionaire and a Russian oligarch want Kirk McGarvey dead. First they send a South African assassin, and when Mac kills him, they commission a Canadian sniper for the kill. When Mac put him down, they hire a team of highly specialized Chinese killers called “Scorpions.” When Mac dispatches them, they send a squad of Russian special ops armed to the teeth with high-tech firepower.

Mac's only chance of survival is to turn on the tables on the people behind this assassination conspiracy, that is, if he can find them.
