Duke Nukem: Time to Kill

Duke Nukem: Time To Kill is a third-person action-adventure game in the series. The game is one of many Duke Nukem titles released to satiate fans while Duke Nukem Forever is in production. The game was released for the PlayStation, and was later remade for the Nintendo 64 as Duke Nukem: Zero Hour with many significant changes.

The gameplay and controls are very similar to those of Tomb Raider, a fact humorously referenced throughout the game. Time To Kill is best described as a fast-paced Tomb Raider II-based game with limited puzzle solving and more of an emphasis on wit and explosions. Aside from Tomb Raider, Evil Dead,, and The Good, the Bad and the Ugly are referenced during the game.

Plot
The game opens with an introduction video sequence of Duke riding his motorbike towards the Bootylicious Club, only to find Pig Cops teleporting in to disrupt his fun. Duke takes out the Pig Cops and the game begins. The video sequence is accompanied by a soundtrack from Stabbing Westward.

The first stage of the game is an "inner city" hub comprised of the strip club, a subway, an apartment and manufacturing plant. On each visit to the hub stage, the appearance and enemies change slightly, and the dancers in the strip club change from babes to mutated pigs and even men, resulting in humorous comments from a disgusted Duke Nukem. The objectives of the hub stages are to find 3 key crystals (hidden in a different location each time) and use them to operate a Time-Space Warp that Duke must use to travel to the Old West, Medieval Europe and Ancient Rome. In each scenario, Duke finds evidence of the aliens and pigs in period dress attempting to change history in their favor. Duke encounters several stages of action before a final confrontation against an enormous end Boss.

The game also features a 2-Player Deathmatch option, where two players can battle against each other in environments loosely based on the single-player stages. 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, and if successful the player gets to keep the weapon in its upgraded form.
