History ShoutOut / ProjectXZone

* In the ending, when Reiji and Xiaomu step inside Demitri's castle and Captain Commando is glad that they made it, Xiaomu comments that she thought they were "[[VideoGame/{{Uninvited}} uninvited]], but then the [[VideoGame/ShadowGate shadow-gate]] swung right open. Gave me the weirdest [[VideoGame/DejaVu deja-vu!]]"

** Chapter 6: [[VideoGame/XenobladeChronicles You Will Know Our Names]]

* One of Valkryie's lines is, "Soar, O noble Icarus! Come! To embrace a magic!'' [[FunWithAcronyms Spelling out the first letter in each word]] gives you Creator/SonicTeam. This is even a ''recursive'' shout-out to the ''VideoGame/BurningRangers'' song "Angels with Burning Hearts", which does the same thing: "Sight of night, I cheer to embrace a magic!"

* Devilotte gets mecha from ''Side Arms: Hyper Dyne'' and ''VideoGame/TechRomancer''. She also ends her attack animation with a [[VideoGame/MarvelVsCapcom Blodia Punch]].

* Jill uses her double knee drop from her appearances in the ''Mercenaries'' games as well as her burning shoulder tackle and four-shot rocket launcher from ''VideoGame/MarvelVsCapcom2''. Her cartwheel kick is her charged melee attack from ''Resident Evil: Revelations''. Chris, conversely, is using a combination of weapons from ''Resident Evil 5'' and ''Revelations'', including the unlockable Hydra shotgun and the Pale Rider revolver. He also has the GrenadeLauncher from ''RE 5'' and used it the same way as in his Hyper Combo in ''MVC3''.

* Mii Koryuji's [[MartialArtsAndCrafts Martial]] [[Manga/RanmaOneHalf Cheerleading]], which bears similarity [[Manga/RanmaOneHalf]]
another couple's dynamic.

** He also makes reference to [[Series/ThePrisoner not being a number, but a free man]] in the Willamette mall stage.

* As usual, Xiaomu's habit of calling her signature ContainmentField "Xiaomu Wave" is one to {{Anime/Dangaioh}}.

* At the end of the ''VideoGame/GhostsNGoblins'' level, Arthur holds the key to the huge gate they got from beating the Stehoneys and exclaims "Open up! I have a key for getting in!", a reference to the phrase mangled by GoodBadTranslation in most of the games that pops up whenever you defeat a level boss.

** Also, in said stage, Xiaomu at one point refers to [[Franchise/DevilMayCry Lady]] as Mud Puppy, a character in ''VideoGame/GainGround'' who also happens to carry around a {{BFG}}.

* Pair up [[VideoGame/GodsEaterBurst Lindow]] with [[Franchise/DevilMayCry Dante]] and [[VideoGame/{{Darkstalkers}} Demitri]] and Dante comments that Lindow's RedRightHand is a ''VideoGame/GodHand''.

* In one chapter, the party ends up at the bottom of a fortress [[spoiler:(The Tarqaron)]]. Since they had to climb up a bit, Bruno remarks how he did not wish to [[Franchise/DieHard scale a building ever again]]. Both [[Franchise/DevilMayCry Dante and Lady]] aren't too happy having to deal with tall buildings either in following chapters.

** Chapter 39: [[Franchise/DevilMayCry The Devil Never Cries]] [[note]]See: the {{Stinger}} of VideoGame/{{Devil May Cry}} 1.[[/note]]

** Franchise/DevilMayCry:

--> '''Xiaomu:''' Yeesh, so much warping. [[StarTrek I think I might boldly barf where no Sage Fox has barfed before.]]

* Xiaomu taps into her inner {{Phoenix Wright}} in her intro in the final chapter complete with an objection.

** It's also a real-life shoutout from the actual battle in the [[https://en.wikipedia.org/wiki/Liberation_of_Paris Liberation of Paris]] with the Allies (consisting of American troops, Free French troops and French guerrilla fighters alongside Spanish Republican exiles) against Nazi German-led forces (alongside Vichy Milice militia forces). During this time, Adolf Hilter supposedly asked military governor Dietrich von Choltitz if he followed his orders to raze Paris rather than allow it to be recaptured by Allied forces with the question "Is Paris Burning?"

* Mii Koryuji's [[MartialArtsAndCrafts Martial]] [[Manga/RanmaOneHalf Cheerleading] , which bears similarity [[Manga/RanmaOneHalf]] another couple's dynamic.

* Mii Koryuji's [[MartialArtsAndCrafts Martial]] [[Manga/RanmaOneHalf Cheerleading], which bears similarity [[Manga/RanmaOneHalf]]another couple's dynamic.

* Mii Koryuji's [[MartialArtsAndCrafts Martial]] [[Manga/RanmaOneHalf Cheerleading]]. That's all.

** Also with Heihachi, [[spoiler: after a majority of the groups return to their home worlds, and the Portalstone is normal again,]] he mentions how he has no use for it and that the ''[[StreetFighterXTekken South Pole]]'' is looking more promising.

** He also likes to reference voice acting gags - he says towards [[VideoGame/MegaManX Zero]] that he can do Cyclone Twisters, which is Roy's Burning Vigor attack. Guess who is Roy's [[RyotaroOkiayu voice actor]].

* There's one scene in Chapter 16 where it's an all out NobuyukiHiyama [[TalkingToHimself shouting at himself]] - the yellow goblins suddenly appear, and they're all voiced by Hiyama. They are followed by a reaction from Haken, Batsu and Demitri, all of who were voiced by the man as well, and Demitri even briefly lapses into goblintalk at the end of his line.

* The game's opening parallels that of ''NamcoXCapcom'''s.

* Jill uses her double knee drop from her appearances in the ''Mercenaries'' games as well as her burning shoulder tackle and four-shot rocket launcher from ''MarvelVsCapcom 2''. Her cartwheel kick is her charged melee attack from ''Resident Evil: Revelations''. Chris, conversely, is using a combination of weapons from ''Resident Evil 5'' and ''Revelations'', including the unlockable Hydra shotgun and the Pale Rider revolver. He also has the GrenadeLauncher from ''RE 5'' and used it the same way as in his Hyper Combo in ''MVC3''.

* In Chapter 23, Urashima says she needs gold and silver to make repairs. Xiaomu mentions seeing "A Gold Cartridge Legend-Of-Something" in the game room. Nintendo fans know this is a reference to the Vintage Gold Cartridge {{The Legend of Zelda}} for the NES.

* Chapter 29 where you must save Zero from his HeroicBSOD? It's called "Unbeatable Love". If you follow [[VideoGame/MegaManX4 the Japanese version of the series]], you might have known that it's another translation of [[AnimeThemeSong its title]] sung by Yukie Nakama.

** Chapter 21: VideoGame/{{The House Of The Dead}}

* When Rikiya Busujima reappears, he ends up outside a zombie-infested mansion. He tells Jill and Chris to be careful, because it's ''VideoGame/TheHouseOfTheDead''. Followed immediately by the chapter title which reads exactly what he just said.

** Chapter 19: [[{{XenoSaga}} Thus Spoke Eternity]]

* Pair up Valkyrie with Riela, and the former will advise the latter to "Use your gifts responsibly, it is the duty of people with great power." Just switch a few words around, and it's similar to the classic line delivered by Uncle Ben in ''Franchise/{{Spider-Man}}''.
