History ShoutOut / EnterTheGungeon

* The Gunjurer enemy teleports across rooms and shoots bullet patterns shaped like squares, circles, and triangles, just like Magikoopas from ''VideoGame/SuperMarioWorld''. Has a double ShoutOut as it can shoot bullet patterns [[UsefulNotes/PlayStation in the shape of an X as well]].

* Fortune's Luck is an active item that references Fortune, one member of the QuirkyMinibossSquad from ''VideoGame/MetalGearSolid2''.

* The Jar of Bees has [[{{VideoGame/MetalGearSolid3SnakeEater}} "The Pain!"]] as its flavor text.

* Gunboots are an item that shoots a spray of bullets every time a player rolls. Its flavor text (They Go Down Well), as well as its Ammonomicon entry, are an obvious reference to "VideoGame/DownWell"

* The Lament Configurum is [[Film/HellRaiser a cursed musical box of mysterious origin]], that when activated, creates a portal that summons [[spoiler:enemies from [[BrutalBonusLevel The Bullet Hell]]]] to assault the player. The object's tagline is ''[[Film/HellRaiser Shellraiser]]'', just to make the reference more blatant.

** Pressing Down, Down, Right and then fire shoots out a [[VideoGame/StreetFighter Hadouken]].

* The Life Orb is named after the hold item from ''VideoGame/{{Pokemon}}'', and its quote refers to the Effort Values that make up a Pokemon's stats. The Macho Brace is another hold item from the same series.

* The Big Iron, as the [[TheWikiRule Enter the Gungeon wiki]] speculates, might be a reference to a Music/MartyRobbins song of the same name. ''VideoGame/DevilMayCry'' fans might see it as Nero's [[http://devilmaycry.wikia.com/wiki/Blue_Rose Blue Rose]], as both of them are magnums with two barrels, one under the other.

* The Misfire Beast, a panther-like creature with two tails that can create illusory duplicates of itself, is a near one-to-one copy of the Displacer Beast from ''TabletopGame/DungeonsAndDragons'', both in looks and in abilities.

* The Trident's tagline ("Under The Sea") references a song from ''WesternAnimation/TheLittleMermaid'', and its synergy with Siren summons Flounder as a companion.

* The Sprun (and the Windgunner you get when it activates) are references to ''Literature/TheStormlightArchive'', more specifically Kaladin's Arc in ''Literature/TheWayOfKings''

* The Brick Breaker looks like it's made out of blocks from ''VideoGame/SuperMarioBros'', and appears to fire Koopa Shells.
* "Lower Case r" is a call-back to ASCII roguelikes such as ''{{VideoGame/Nethack}}'' and ''{{VideoGame/Rogue}}'', where items and enemies would be represented by ASCII symbols.

* The Mac-10's description ("$#!^@ Never End") is a reference to the song Who Got Gunz by GangStarr. It also has a synergy with the Eyepatch, as a reference to Snake Plissken from ''Film/EscapeFromNewYork''.

* The Combined Rifle is pretty much just the Overwatch Standard Issue Pulse Rifle (aka the AR2) from ''VideoGame/HalfLife2'', co-opted by the Hegemony of Man after the liberation of Planet 17. Its two alternating attacks are the AR2's primary and secondary fire.

** One of the Heroine's synergies involves the Pig - when the Pig dies it doesn't just revive you with full health, but also temporarily makes the Heroine one of the single strongest weapons in the game, in reference to Samus gaining the Hyper Beam during the last boss of ''Super Metroid''.

* The concept of the [=VertebraeK=]-47 being a gun constructed out of bones may be an indirect reference to the 'Gristle Gun' from the Creator/DavidCronenberg movie ''Film/eXistenZ''.

* The Brick Breaker looks like it's made out of blocks from VideoGame/SuperMarioBros, and appears to fire Koopa Shells.

* The Banana weapon works similarly to the one in ''{{VideoGame/Worms}}''.

** One of the Heroine's synergies involves the Pig - when the Pig dies it doesn't just revive you with full health, but also makes the Heroine one of the single strongest weapons in the game in reference to Samus gaining the Hyper Beam during the last boss of ''Super Metroid''.

* The Lichy trigger finger is stated to ''not'' be the [[TabletopGame/DungeonsAndDragons lich's phylactery]].

* The Shotgrub's pickup quote is [[WesternAnimation/TheLionKing "No Worries"]].

* The Alien Sidearm (Shield Breaker) pistol is a [[{{Franchise/Halo}} Covenant Plasma Pistol]], complete with the charged shot for maximized damage. The flavor text also references their absurd commonness within the games. The design of the gun itself, however, bears more resemblance to the Plasma Pistol's automatic relative, the Plasma Rifle, and will fire in a similar manner with a certain weapon synergy.

* The "Serious Cannon" works similarly to the cannonball launcher from VideoGame/SeriousSam. Its flavor text even outright states Sam himself brought the weapon into the Gungeon!

** Holding the Klobbe and AU Gun at the same time makes the impossible possible, which means the Klobbe becomes even more inaccurate.

* The Wind-up Gun is the same gun from ''{{WesternAnimation/Futurama}}'', down to the "Pop Goes The Weasel" song when you wind it.

** Its description is "2D6 + Int Mod", resembling a standard damage roll in the game.

** One of the Heroine's synergies involves the Pig - when the Pig dies it doesn't just give you a last chance, but also makes the Heroine one of the single strongest weapons in the game in reference to Samus gaining the Hyper Beam during the last boss of ''Super Metroid''.

* The Raiden Coil fires out the iconic "toothpaste laser" from the ''VideoGame/{{Raiden}}'' series.

** It even makes a synergy with The Heroin (Samus' ArmCannon)!
