This is an action-adventure game in which players take control of a character named Duke Nukem, who must complete objectives such as locating fusion cells and finding missing agents. Players traverse city environments, blow up buildings and vehicles, engage in hand-to-hand combat, and shoot alien creatures that scream out when shot. Players use machine guns, sniper rifles, and rocket launchers to kill the pig-like aliens and other fantasy creatures. The dialogue often contains one-liners with sexual references (e.g., "I need to rescue the babes . . . from their virginity," "I got time for a quickie," and "Ménage à trois comes to mind"). In one sequence, the central character enters a casino and offers money to a stripper, telling her to "shake it, baby." Language such as "a*s" and "bastard" can also be heard in the dialogue.
