Shout Out / Enter the Gungeon

Essentially being one giant love letter to video games and especially pop culture in general, it would make sense for Enter the Gungeon to be at just a wee smidge Reference Overdosed now, right?

References to From Software games

• Dodge-rolling is a core mechanic of the game; it makes players temporarily invulnerable and can even be used to clear gaps. The dev team considered it such an important feature of the game that they named themselves after it.
  • The Cloranthy Ring also appears as an item, boosting the speed of the dodge roll and reducing the time between rolls, similar to how its Dark Souls counterpart reduces downtime between moves.
• Red Explosive Barrels appear as literal wooden barrels (in contrast to the metal-looking ones that hold other materials), just like in the Souls games, and can be harmlessly destroyed by rolling through them.
• Poison and Curse have a bar that fills up the longer players are standing in it, only causing damage once it's full.
• You can eventually find friendly characters who are trapped in cells and free them by finding the keys. They will then either return to the Breach or appear sporadically in subsequent runs as shopkeepers or quest-givers. This is similar to how NPCs in the Souls games could be found and sent back to the hub areas (the Nexus, Firelink Shrine, Majula) or to their homes elsewhere in the game world.
• The fish knight sitting outside of the tutorial area is essentially one of the several Crestfallen Knights from Demon's Souls and the Dark Souls series in terms of mannerisms. The Crestfaller gun, which is implied to have been originally owned by him, only solidifies the reference.
• In the later chambers, you'll discover Ashen Bullet Kin, referencing the Unkindled and the Ashen One from Dark Souls III.
• The Sunlight Javelin hurls spears of light, like the Sunlight Spear miracle from Dark Souls. Its description says that it makes enemies "grossly incandescent" and was born from two heroes who worked together, alongside its unlock condition being to beat the High Dragun with a companion or a second player - all references to the Dark Souls character Solaire, who is both associated with the sun and cooperation. During Rainbow Mode, Bowler also has a small chance of standing on top of a chest in a "praise the sun" pose instead of sitting on top of them like normal, further referencing Solaire.
• There's also the Gun Soul, which mimics the game mechanic in the Souls series of having to return where you died to recover your souls (or in this case, your equipment). It even has synergies with all of the other Dark Souls themed items.
  • Gun Soul + Old Knight's Flask = Praise the Gun
  • Gun Soul + Sunlight Javelin = \o/
  • Gun Soul + Crestfaller = Crestfallen Soul
• The Old Knight's Flask is basically the Estus Flask. It has a synergy with the Crestfaller (as do other potables).
• Keybullet Kin and Chance Kin are basically Crystal Lizards, running away from the player and despawning after a set period of time if not killed, but granting valuable loot if they are.
• Mimics also behave similarly to their Dark Souls brethren: they slightly open their lid to breathe, start with a high-damage point-blank attack if you try to open them, and possess miniboss-level strength. But they do drop a real item equivalent to what a chest that color would contain. You can also attack the chest to test if it's a mimic or not (causing them to aggro), but if you damage a real chest too much, it will break leaving only junk inside.
• The Trick Gun changes between a revolver and a shotgun every time it's reloaded, which is similar to how trick weapons work in Bloodborne.
  • The reference is solidified by a Synergy between the Trick Gun and Blood Brooch, an item that references Bloodborne's Bright Red Brooch.
  • The Synergy gets even MORE solid if you add Silver Bullets in the mix, as Hunters in Bloodborne use similar ammunition.
  • The Synergy between the Trick Gun and the Huntsman is called "Insight", and allows the player to see a tentacled monster perched atop breakable walls that hide secrets behind them. Sound familiar?
• The Shield of the Maiden's description ends with a line from Bloodborne's Wood Plank shield: "Shields are nice, but not if they engender passivity."
• The way enemies' bodies continue to block bullets for a brief time after death may be referencing the way Bloodborne's enemies can still be hit (for potential health recovery) briefly after they die.
• The jars of "curse" from Dark Souls II make an appearance, and behave exactly the same way: Standing within the miasma they emit builds up the curse bar, and they can be destroyed in a single hit to remove the miasma.

Guns

• The Mega Hand is Rock's signature weapon. It synergizes with other guns and items to recreate the eight Special Weapons in Mega Man 2, with varying degrees of success.
• The Alien Sidearm (Shield Breaker) pistol is a 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 the fittingly called Chief Master synergy gained by having any 2 Master Rounds at the same time.
• The Shotgrub's pickup quote is "No Worries".
• The Pulse Cannon, despite behaving like a shotgun, has the visual form of the Pulse Rifle from the Alien franchise.

• The Laser Lotus ("Level 5") is a reference to Community character, Pierce Hawthorne. In the show, Pierce is a Reformed Neo-Buddhist, and refers to himself as a "Level 5 Laser Lotus." For bonus points, the first two words describing the weapon are "Pierce weapon," as both another shout-out and to reflect that its ammo pierces enemies.
• The Super Meat Gun increases your movement speed and fires sawblades, as a reference to Super Meat Boy.
• The Judge is modeled after the "Lawgiver Mark II" used by Judge Dredd. The description, "Hot Shot", comes from a scene from the 2012 reboot film.
• The Moonscraper is named after the film Moonraker, and designed after the lasers from the film in question.
• SAA not only replicates Revolver Ocelot's signature reloading method and ability to bounce bullets off walls, but its flavor text quotes his observation of it having "Exhilarating Reload Time". It probably helps that it's Ocelot's favorite gun.
  • The reference is extended further by a synergy between the Cardboard Box, Ration, and SAA.
• The Light Gun is very clearly a Zapper, and it drives the point home by shooting pixelated ducks at enemies and summoning the Dog to hit the enemy when its synergy effect is active. Its flavor text mentions it’s a third-party item.

• The Jolter is a Bolt Pistol (".95 Caliber") from Warhammer 40,000, with the flavor text describing it as firing "unreasonably large bullets." and was used against thick-skinned mutants (Orks).

• The Quad Laser fires a single, slow-moving bullet made out of "Moon Energy", as a reference to the Mooninites from Aqua Teen Hunger Force.

• The Banana weapon works similarly to the one in Worms, bouncing around before exploding into smaller banana-shaped Bombs.
• The BSG is an ersatz version of the BFG from Doom.
  • Thunderclap is the Plasma Gun come from the same game.
• The "Black Hole Gun" is a reference to the song "Black Hole Sun" by Soundgarden, along with its description.

Its synergy with the Devolver gun also makes it launch one of the screaming headless zombies from the SS franchise that explode when they hit an enemy.
• The "Com4nd0" is the quad-barrel rocket launcher from Commando. Its flavor text ("You're fired!") references another Arnie movie, True Lies.
• The Fightsabre is really just a lightsaber gun, right down to the iconic noise when you're swinging it during a reload. It reflects back your enemies' bullets while reloading. In a twofer shoutout, it looks like an Astra Militarum lasgun.
• Both the Yari Launcher and the Demon Head are taken straight from the new Shadow Warrior, and Zilla Shotgun comes from the classic Shadow Warrior.
• The Magnum revolver references Dirty Harry in both its pick-up quote and its flavor text.

• The AU (AU being the chemical notation for gold) Gun is the Golden Gun of The Man with the Golden Gun.
• The Klobbe references the Klobb from the Nintendo 64 GoldenEye game, including the incredible inaccuracy and low damage output — that is, it sucks in this game, too.
  • The now-removed synergy between the Klobbe and AU Gun at the same time made the impossible possible, which meant the Klobbe became even more inaccurate.
• The Mac-10's description ("$#!^@ Never End") is a reference to the song Who Got Gunz by Gang Starr. It also has a synergy with the Eyepatch, as a reference to Snake Plissken from Escape from New York.
• The Flash Ray is the gun from Space Ace. Its flavor text is "Ah Ahhh!" and its synergy with the Camera is called "Savior of the Universe".

• The Flame Hand references Dungeons & Dragons' "Burning Hands" spell.

• The Patriot is the same gun that The Boss wielded in Metal Gear Solid 3: Snake Eater. The description notes that despite being overcomplicated, it is still beloved by many despite its flaws (which is often used to describe the series itself).
• The Magic Lamp is, as you may have guessed, a lamp with a blue genie in it.
• The Heroine is Samus Aran's Arm Cannon, and its synergies invoke the Plasma, Ice, and Wave Beams, complete with their elemental effects and arm cannon transformations like in Metroid Prime. The Wood Beam is a reference to a memetic joke revolving around Super Metroid.
  • 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.

It shares the design of the 5th model from A Crack In Time and their overall reputation as extremely dangerous and illegal black-market weapons, if its Ammonomicon Entry is anything to go by. Instead of launching a tremendous volley of missiles, though, it fires a giant laser after a charge-up period, which brings it closer in function to the RYNO IV.
  • Its tagline quote "Return To Dust" also likely references a Magic: The Gathering card of the same name.
• The Rattler's flavor text is "Snakes On A Gun".
• The Gunzheng is a reference to Kung Fu Hustle. It's a Chinese musical intrument that fires arrows, as in this scene.

• The Tangler and Sponge synergy is a reference to Spongebob Squarepants.
• The Mutation is a reference to the character Horror from "Nuclear Throne", who had an ability to shoot pure radiation.
• The Big Iron, as the Enter the Gungeon wiki speculates, might be a reference to a Marty Robbins song of the same name. Devil May Cry fans might see it as Nero's Blue Rose, as both of them are magnums with two barrels, one under the other.

• The STRAFE© Gun comes from...well, Strafe.

• The Laser Rifle is likely a reference to X-COM: UFO Defense - the description mentions how it is known for its low maintenance and production costs, and refers to it as the AK-47 of the future. The Laser Rifle is infamous in UFO Defense circles because it can be manufactured at no resource cost and sold for a profit, in addition to being Boring, but Practical - exactly like the real-life AK-47. These two factors ensure it will see a LOT of use in any given playthrough. ETG's Laser Rifle also resembles UFO Defense's in both appearance and function.
• The concept of the VertebraeK-47 being a gun constructed out of bones may be an indirect reference to the 'Gristle Gun' from the David Cronenberg movie eXistenZ.

  • Piling on the Metal Gear Solid references is the revelation that the Sell Creep is actually Agunim, who pilots what is essentially a HIND D and makes grandiose (Cam Clarke-voiced) rants about his destiny.

Items/Miscellaneous

• One of the items you can find is a melted rock which can blow up enemy corpses, a reference to Melting from Nuclear Throne.

  • In addition, the splash screen for the Pilot's true ending is him sharing a drink with his partner, a blue falcon.
  • Like all other characters, the Bullet gets an alternate skin for beating his past. His skin makes him into a pink bunny, not unlike what happens to Link when he enters the Dark World in A Link to the Past, and is also rather similar to Ravio's outfit in A Link Between Worlds. The alternate outfit is represented by a mirror in the Breach, a parallel to the Magic Mirror that allowes Link to move between the Dark World and the Light World.
