The Duke Nukem franchise started early in TheNineties as a series of regular side-scrolling [[PlatformGame platformer games]]. It started under Apogee Software[=/=]3DRealms development, but in 2010, the rights of the series went to Gearbox Software.

The series is composed of several games which follows a loose continuity:

[[index]]
* ''VideoGame/{{Duke Nukem|I}}'' (1991)
* ''VideoGame/DukeNukemII'' (1993)
* ''VideoGame/{{Duke Nukem 3D}}'' (1996)
* ''VideoGame/DukeNukemManhattanProject'' (2002)
* ''VideoGame/DukeNukemForever'' (2011)

%% Don't pothole the below, otherwise, it screws the index.
There were also several spinoffs for consoles.

* ''Duke Nukem: Time to Kill'' (1998)
* ''Duke Nukem: Zero Hour'' (1999)
* ''Duke Nukem: Land of the Babes'' (2000)

There are also hints of a [[http://en.wikipedia.org/wiki/Duke_Nukem_(character)#Proposed_feature_film live-action film]] being made.

And, as a bit of bad news after ''VideoGame/DukeNukemForever'', Gearbox has shown their lack of support for the fan-made Unreal Engine remake of Duke Nukem 3D by fan studio Interceptor, telling them that they could "keep developing it, [[InsaneTrollLogic as long as they don't distribute it]]".

!!Tropes found across the series include:
* AwesomeMcCoolname
* {{Badass}}: Duke Nukem, of course!
* BagOfSpilling: In the first three games, Duke loses all weapons he picks up across episodes. Averted in ''Forever'' [[spoiler:until the final battle]].
* BrassBalls: One of VideoGame/DukeNukem's catchphrases.
--> ''"I've got balls of steel!"''
** The company that made ''VideoGame/DukeNukem'', 3D Realms, later released a {{pinball}} game named ''VideoGame/BallsOfSteel'', which featured a Duke Nukem-themed table.
* BondOneLiner: Duke is rather fond of these.
* CanonDiscontinuity: The [[GaidenGame third person shooters]] ''Time to Kill'' and ''Land of the Babes'', for the original Playstation, while decent in their own right, aren't regarded as canon. The fact that they were made by different developers probably has something to do with that.
* ChivalrousPervert: Duke is a royal jackass who has no problem shitting down an alien behemoth's neck after killing it, but he will never insult a woman directly.
* CoolShades: From ''3D'' onwards, now became an iconic feature of his character.
* DamselInDistress: All of Earth's women.
* EarlyInstallmentWeirdness: The third game presented a massive shift in both genre and tone.
* InconvenientlyPlacedConveyorBelt: All four installments to date have at least one.
* LockAndKeyPuzzle: The games are full of them. Lampshaded in ''Forever'', where the trope takes on a more creative twist.
* ManInAKilt: Believe it or not, Duke himself wears a kilt in the Medieval levels of ''Time to Kill'', and a tunic in the Ancient Roman levels.
** CensorShadow: Most of the time, except . . .
** {{Mooning}}: . . . in an EasterEgg, where he imitates ''Film/{{Braveheart}}''.
* MascotMook: The L.A.R.D pig cops have become this.
* NamesToRunAwayFromReallyFast: Duke Nukem. Kinda obvious to see what happens when you piss him off.
* NegativeContinuity: {{Zigzagged|Trope}}. The guns at the Duke Museum in ''Forever'' state that they were used by Duke in 1996 ... which refers to the year when ''3D'' came out. ''II'' was supposed to happen in 1998, since ''Duke Nukem'' is set in 1997, and the introduction of ''II'' mentions "defeating Doctor Proton last year", with ''3D'' happening immediately after ''II'''s conclusion. However, the ''Balls Of Steel Limited Edition Guide'' says: "This pegs the original invasion around 1999, which works out, since ''Duke Nukem'' and ''Duke Nukem II'' are set in the then-near future of 1997 and 1998."
* OneManArmy: Duke Nukem, alone, takes on a mad scientist and his robot army, followed by two alien armies, the latter of which had already at least partially conquered Earth the first time. Acknowledged in a 2001 trailer of Duke Nukem Forever when a SWAT Officer asks "Hey pal, what are you gonna do, save the world all by yourself?"
* PinballSpinoff: ''VideoGame/BallsOfSteel''.
* PopCulturedBadass: Duke, of course.
* PreAsskickingOneLiner: Duke has many of these.
* RatedMForManly: And how!
* RefugeInAudacity: Duke's bread and butter.
-->''The Secret to Duke's Humor is that he and his universe actually are serious. In his world, it makes perfect sense for families to be visiting the Fellatio hotel (i.e., the Bellagio) in Las Vegas. Everything in his world is real for them, authentic. It's only when we look at it through the lens of our world that we get the joke.''
-->--'''[[WordOfGod Randy Pitchford]]''', April 2011 US Xbox 360 Magazine on why the game's humor is so effective.
* SeeYouInHell: Duke sometimes says this whenever he blasts enemies into oblivion.
* ShoutOut: Check [[ShoutOut/DukeNukem the page]].
* StoppedNumberingSequels
* TestosteronePoisoning
* TookALevelInBadass: It's hard to believe that, once upon a time, [[RealMenWearPink Duke wore a pink shirt and watched Oprah]], his hair was curly and his language never strayed beyond BadButt and GoshDangItToHeck Then something happened in between the two alien invasions...
