Duke Nukem: Time to Kill is a third-person shooter video game developed by n-Space and published by GT Interactive for the PlayStation.

The gameplay and controls are very similar to those of Tomb Raider, though with an emphasis on action rather than on exploration. The game humorously references Tomb Raider throughout, as well as The Evil Dead, Monty Python and the Holy Grail, the Back to the Future series, The Good, the Bad and the Ugly and the song "I Got You (I Feel Good)" by American singer James Brown.

The game also features a two-player deathmatch option, where two players can battle against each other in environments loosely based on the single-player stages referring to the different time periods. The multiplayer stages can also be accessed in the single-player game by finding stopwatches or 'Surprises.' If these hidden items are found, the player is given an opportunity to take on a horde of enemies in the multiplayer stages using an upgraded version of the current weapon used, with the prize for completion being to keep the upgrade for the remainder of the game.
