Duke Nukem: Time to Kill

Duke Nukem: Time To Kill is a third-person action/adventure PlayStation video game in the Duke Nukem series. The game is one of the many Duke titles released to satiate fans while Duke Nukem Forever is in production.

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

Plot
The game opens with an introduction video sequence of Duke riding his motorbike towards the strip 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 a hub stage. It is an "inner city" 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 women 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 Wild West, Medieval Europe and Ancient Rome. In each scenario, Nukem finds evidence of the aliens and pigs in period dress attempting to change history in their favor. Duke faces several levels of action before a final confrontation against an enormous end Boss. The game was remade for the Nintendo 64 as Duke Nukem: Zero Hour, although there are considerable differences.

There is also a multiplayer deathmatch option, where 2 players can battle each other in environments loosely based on the single-player stages referring to the different time periods. These 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 upgradeded version of a current weapon, with the prize for completion as the upgrade.

Stages
Stage 1 - Present Time New L.A. - Above Ground: The major section of the hub stage that Duke explores throughout most of the start of the game before going back in time. The area mainly consists of the Bootylicious Club (a strip club and bar), a main street which connects to a backalley where there is a back-entrance into an apartment belonging to a dominatrix. There is also a large warehouse that is locked off and a factory as well. There is also an entrance to the subway station. Subway: This is where the teleporter is located that enables Duke to travel back in time to the various time-periods of which his ancestors existed. However, before he can use the time teleporter he must find the 3 key crystals that are scattered throughout this stage.

Stage 2 - The Old West - Duke now wonders what the aliens are up to in the Old West. But, to find out, he needs to get inside the bank vault. Then, once he knows it, he can grab a key and storm the nearby garrison, where a mine shaft has been excavated. That shaft brings him to end. The important thing now, though, is to find the three pieces of paper scattered through the level that hold the combination to the bank vault.
 * Missions: Duke Hill, Miner 69er, Gold and Guns, The Reaper (Boss Stage)

Stage 3 - Alternative Future New L.A. - Welcome back, Duke. Unfortunately, instead of a hero's welcome, things are even worse than when he left. Like level 1, the idea here is to collect the crystals and warp back to another time. Unlike level 1, this time Duke enters an area he was unable to explore before: the warehouse. The whole of New L.A. seems to have been taken over by the alien race since the events in the second level.
 * Mission: Obey or Die

Stage 4 - Medieval Times - Duke starts this level standing across a moat from a castle owned by his long-gone ancestor Baron Von Nukem. He must now storm into the castle and recover all the pieces of his family's treasured jewels in order to return back to his time.
 * Missions: The Family Jewels, Resistance is Feudal, Holy Terror, Wing'ed Death (Boss Stage)

Stage 5 - 'Still Not Quite Right' Future New L.A. - As always upon return to the present, Duke is found in the small park right outside the bar (now called Danglers with male dancers). Obviously things are still not right, and Duke must go and fix it, in order to do so he must repair the time portal which has been flooded in and is also missing a piece for the orientation device. In order to recover this piece Duke needs to fight his way through the pig-infested factory.
 * Mission: Pig Factory

Stage 6 - Imperial Rome - Duke is now sporting a toga as he enters the Roman Era. He starts out in a small hallway overlooking a Roman bath holding some very fine looking Roman women. Here Duke must battle his way through the Roman bath house in search of a key and pass through an arena filled with nasty surprises which will eventually lead him to a labyrinth that will conclude in a Roman palace. However before Duke can finish in this time he must confront the unholy bloody bath house which hosts the final Boss.
 * Missions: Hog Heaven, Let the Games Begin, Blood Baths, Moloch the Gatekeeper(Boss Stage)
