Duke Nukem/Shout Out

The series is the ancestor of all first person shooter nods to both films and other videogames.

As such, every Continuity Nod, Mythology Gag, Captain Ersatz, "No Celebrities Were Harmed", Expy, and Shout-Out reference in any of these games go here.

Duke Nukem and Duke Nukem II

• In the "Mercury Mines" level of Duke Nukem 1, Dr. Proton issues a taunt via a monitor:^[1]

"Why bother Duke? Not even Commander Keen could survive the perils of my Mercury Mines!"

Duke Nukem 3D

• E1L1, "Hollywood Holocaust":
  • The level is based on Escape from New York.

• E3L4, "L.A. Rumble", has a building that crumbles due to an earthquake looks exactly like the building where id Software's offices are in. While the building crumbles Duke will state "I ain't afraid of no Quake!"
• E3L5, "Movie Set" is a movie set where a film based on the previous episode is being filmed. The helicopter that crashes at the start hits a water tower (a possible shout-out to Warner Bros, there). The poster for the film shows up in a couple of later levels, too.

• The PlayStation port (Total Meltdown) has a control scheme called "Doomed", named such because it's based on the default control scheme of the Playstation Doom port.

"Say hello to my little friend."

• In the first level, there's an outdoor to the "Rats" play, a reference to Broadway's "Cats".

• • Later, you must avoid some cars crossing a street. After a couple of times:

"What am I, a frog?"

• After taking a Berserk pack, Duke sprouts this:

"It's clobberin' time!"

"Oops, I did it again!"

• The secret boss Wozma seems to be a reference to Ozma.

Johnny Carson, Conan O' Brien, Jay Leno and David Letterman

  • Or "It's all in the reflexes."
• When the first Battlelord appears, Duke yells, "You are one, ugly motherfucker!"
• At one point, Duke finds ^{[dead link]} a certain set of green armor, and snarks, "Power armor is for pussies!" Overlaps with Mythology Gag, since Duke found a dead Doom marine in Duke Nukem 3D, which he commented, "That's one DOOMED marine!"
  • Also overlaps with Take That, aimed at God Mode, as the Marine says "Duke, we got your green power armor!" just before Duke snarks at him.
• Duke comes across an EDF soldier who knew Duke's retirment "bullshit was just bullshit". He then goes on in a mocking voice about how he just helped one of his friends find his wife and calls his friend a pussy.
• The game's Regenerating Health bar being an Ego bar might be a reference to the Ego system on Duke Nukem: Manhattan Project, where Duke would get ego by shooting things, freeing women and, of course getting ego boxes.
• The first level of the game is a boss fight against the Cycloid Emperor, last boss of the third episode of Duke Nukem 3D, taking place in the very same stadium...sort of.
• The "Balls Of Steel" edition and the achievement of the same name might be references to an old 3D Realms pinball, and a Shout-Out to a line that quickly became memetic due to a harassment video where Duke's voice lines from Duke Nukem 3D were played to infuriate a Ventrilo server admin.
  • "I'ma kill you old style!" is a reference to said harassment.
• Duke's autobiography, "Why I'm So Great," was first mentioned in Duke Nukem II.

• The four-digit code that Duke enters into the Super Turret is 1138.
• Duke's monster truck is called Duke's Mighty Foot.
• The twins that appear in the game are called the Holsom twins, alluding to the Olsen Twins. This is not the only reference they are to, however, since their multiplayer reward description is "2 Girls, 1 Duke", referencing infamous Shock Site 2girls1cup.
• Several in the Strip Club level:
  • There's a sign saying "Open Dusk Till dawn".
  • A cash terminal showing the message "Feed me a stray cat".
  • A spintop which doesn't stop spinning. This is a clue that the level is All Just a Dream.
  • The answering machine next to the top mentioned above will replay the message "Tonight... you!"
  • The toilet has "REDRUM" written on the wall opposite the mirror
• In a specific part of the chapter "The Hive", a decapitated soldier and a very familiar-looking helmet can be found, which Duke comments on by saying "That is one Dead Space marine!"
• You get an achievement for sticking enemy with a laser tripmine called "Sticky bomb like you!"
• Early in the "Vegas in Ruins" chapter, Duke gets assigned to accompany a private named Jenkins. He immidiately runs right ahead of you into the action, disregarding any tactics, and as a result, he dies quickly. Sounds familiar?

• All of the cash registers have the value of $847.63
• "I'm from Las Vegas and I say kill 'em all!"
• In the freezer room with all the pipes, Duke says "I hate valve puzzles."
  • Perhaps doubling as a shout-out to Francis.
• When Duke stomps on a tiny Pigcop in Duke Burger, one of his lines is "Better then Freckle Bitch's!"
• "Duke Burger" itself may be a Stealth Pun on "The Burger King" (because Duke is King).
• In one part of the Hoover Dam, Duke ascends a long spiral stairway while dodging incoming barrels, remarking "Where's a hammer when you need one? He finds a Pigcop at the top, but remarks he was expecting a monkey.
• The ending is a parody of Jackson's death and the ending of Call of Duty 4: Modern Warfare, to which Duke replies "What kind of shit ending is that?"
• The girl in the Duke Burger kitchen may wonder if "there'll be another season of Lightning Bug."
• Behind the set of the "Damn It's Late Show" there's a stage hand getting berated by an angry actor for walking across the stage during filming, a parody of Christian Bale's infamous rant on the set of Terminator Salvation. Duke can even punch him out:

Stage Hand: "Thanks Duke. That guy was a douche."

• After killing the Triple Boob Monster, nearby is some evidence Sam and Max Freelance Police were there.
  • On seeing the said monster, Duke quips, "Baby, you make me wish I had three guns", a reference to the Total Recall.

• One of the ambient music files is named WormHole_Xtreme.

• When shrinked during Duke Burger stage, during navigating a room with electrified floor, music suspiciously reminiscent of Mouse Hunt will play.
• The first DLC includes quite a bit of snapping towards other multiplayer games and websites, with new maps called "Call of Duke" and "2forts1bridge".
• Octobrains, underwater. Does this reminds you of anything?
• America, Fuck yeah!

Other Duke games

• In one level of Duke Nukem: Time to Kill, Duke can come across the Delorian from Back to The Future.
  • In another, he finds the corpse of Lara Croft.
• The Bad Future of Zero Hour, has the Statue of Liberty half-submerged in nukage, a reference to Planet of the Apes.

1. ↑ The Duke Nukem 1 engine is very similar to the Commander Keen: Invasion of the Vorticons engine, as evidenced by playing both for at least half an hour each, and probably explains why the credits for Duke Nukem 1 include Tom Hall.
