No One Lives Forever description from Wikipedia:
It is the second game in the No One Lives Forever series, an official sequel to the 2000 game The Operative: No One Lives Forever. The story follows super-spy Cate Archer as she once again takes up arms against the international criminal organization H.A.R.M. This second game features even more exotic locales, such as a ninja village, a secret submarine base, and a trailer park in Ohio during a tornado. A whole new range of outlandish gadgets and weapons are also introduced, including a blowtorch disguised as a can of hair spray and a robotic bomb disguised as an adorable kitten. A spin off to the game, entitled Contract J.A.C.K., was released in 2003.
