A story-driven game set in the 1960s, No One Lives Forever has been critically acclaimed for, among other things, its stylistic representation of the era in the spirit of many spy films and television series of that decade, as well as for its humor.

In addition to a range of firearms, the game contains several gadgets, which are disguised as ordinary female fashion items.
