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 whilst Duke Nukem Forever was being produced.

Plot
The game starts with a video sequence of Duke riding his bike toward a strip club, only to find pig-cops teleporting in to disrupt him. Duke fights off the cops and the game begins.

The first level of the game is a hub level. It is an inner city comprised of a subway, strip club, apartment and manufacturing plants. On each visit to the hub level, the appearance and enemies change slightly, and the dancers in the strip club change from women to pigs and finally men, resulting in humourous comments from a disgusted Duke Nukem. The objectives of the hub levels are to find three crystals (hidden in a different building each time) and use them to operate a time machine that Duke uses to travel to the wild west, Medieval Europe and imperial Rome. In each scenario, Nukem finds evidence of the aliens and pigs in period dress attempting to change history in their favour. Duke faces several levels of action before a fight against an enormous Boss. The storylien and level design is very similar in ethos to Duke Nukem: Zero Hour.

There is also a multiplayer deathmatch where two players can battle eachother in environments loosely based on single player levels. These multiplayer levels 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 levels using an upgradeded version of a current weapon, with the prize for completion as the upgrade.
