''Hyperdimension Neptunia mk2'' (''Chōjigen Game Neptune mk2'') is a ContinuityReboot to ''VideoGame/HyperdimensionNeptunia'', and the second game of the ''VideoGame/{{Neptunia}}'' series.

The four goddesses and Nepgear are captured while trying to take down ASIC. Three years later, Nepgear is freed. She must now save her sisters and hopefully succeed at taking ASIC down this time.

But she doesn't have to go at it alone. Most[[note]]everyone except RED, since the company she represents was bought out between games[[/note]] of the cast from the original, plus several new additions, are there to support her.

Of course, this includes the younger sisters of the other goddesses, who are based on the handheld systems on the market at the time of this game's release, much like how Nepgear is based on the UsefulNotes/GameGear and how the goddesses are based on the home consoles on the market and the unreleased Sega Neptune.

A remake for the UsefulNotes/PSVita was later released, titled ''Hyperdimension Neptunia [=Re;Birth2=] SISTERS GENERATION'' (''Chō Ji Jigen Game Neptune [=Re;Birth2=] SISTERS GENERATION''). Akin to the earlier remake game for the PS Vita, ''VideoGame/HyperdimensionNeptuniaReBirth1'', this game also utilises the battle system from ''[[VideoGame/HyperdimensionNeptuniaVictory Victory]]'' in addition to ''[[VideoGame/HyperdimensionNeptuniaReBirth1 Re;Birth1]]'''s "remake system", which unlocks special modifications to the game. The remake features an improved framerate compared to the performance of the original [=PS3=] game, in addition to [[UpdatedRerelease reworked voice acting, music and visuals]].

In addition to most of the original cast, the remake also features the characters representing game developer companies from ''Victory'', in addition to Cave, 5pb, RED, and the four Oracles of each continent; [[PutOnABus both Gust and Nisa have been removed from the game, however]].

The aforementioned remake was ported to PC and was released on May 29. A Closed Beta test for said port began on April 13th of the same year.

This page is littered with spoilers! Please use extra caution.
!!Tropes in ''Hyperdimension Neptunia mk2'':
* AllJustADream: Noire and Kei both have dream sequences in which CFW Brave asks them for permission to marry Uni.
* AlternateUniverse: Honestly, just about everything has changed outside of the central premise. Even the world's structure and how the main characters met! This Gamindustri is now officially known as the Hyper Dimension, while the [[VideoGame/HyperdimensionNeptunia previous]] Gamindustrie is known as the Super Dimension.
* ArtisticLicenseBiology: Mushroom enemies are classified as plants even though they're actually fungi, a completely separate living organism from plants. Though this is probably justified and perhaps deliberate because ''Neptunia'' is based on video games, so it is likely basing the enemies off of a common mistake that most developers fall victim to when comparing fungi to plants.
* BeachEpisode: In one scene, Histoire needs people to deal with octopi suddenly falling from the sky. The problem is that they're on a beach preserve where no weapons are allowed, and they can't come in with their regular clothes for risk of contamination, and must wear supplied swimsuits instead. Naturally, we get an image of the CPU Candidates in the swimsuits while an extended dialogue plays out.
* BonusBoss: Tons in the coliseum, the hardest of them being [[spoiler:Delphinus]].
* BraggingRightsReward: Getting the accessory that allows you to break the damage limit. Why's that? [[spoiler: You only get this accessory as a rare drop from beating ''the highest leveled enemy'' of this game.]]
* CallingYourAttacks: You can't name your combos this time out, but the characters are more prone to shouting their attack names.
* CreatorCameo: When was the last time you've seen a creator of the game (or at least, have a hand in making the game aka Keiji Inafune) be there in person ''as a friggin summon''!?
* DarkerAndEdgier: Definitely compared to the first. [[spoiler: '''''especially''''' if you're on the Conquest Ending. The multiple cases of Assisted Dei-Suicide alone would have contributed to it's M rating.]]
* DarkestHour: The absurdly disturbing Conquest Ending for the entire cast. Nepgear is forced to [[spoiler:kill all of her CPU friends and her only living relative, all in a last-ditch attempt to prevent the end of the world. And it's heavily implied that her actions didn't prevent the tragedy, but in fact ''ensures'' it.]]
* DatingSim: The [[LesYay Lily system.]] [[VideoGame/AgarestSenki Possible shout out to another game by Compile Heart.]]
* DecidedByOneVote: One side event has the [=CPUs=] holding an election to determine who is the most popular after Neptune and Nepgear put out an IdolSinger video that proves to be immensely popular. It appears to end in a Type 3 as Underling, who showed up just to mess with the whole thing, is pressured into voting by the bickering goddesses. [[spoiler:She ends up fleeing with the [=CPUs=] in pursuit.]]
* DownerEnding: [[spoiler:The Conquest Ending is heavily implied to be this. See DarkestHour above and ShootTheShaggyDog.]]
* DubNameChange to match with the similar treatment for the [=CPUs=], any instances of "_____ the Hard" were changed to "CFW _____"
* EquipmentSpoiler: Trailers and screenshots sure love showing off [[spoiler:Nepgear's [[SwordOfPlotAdvancement Magic Sword]] in which you can only obtain after finishing with the Conquest End and start a NewGamePlus.]]
* {{Fanservice}}: Wouldn't be Neptunia game without it.
* FightingYourFriend: [[spoiler:In the Conquest Ending, Nepgear, Neptune and the Makers end up fighting the other goddesses.]]
* FiveManBand: Lampshaded by Nepgear and Nisa with the following party members.
** TheLeader: Nepgear (though Nisa fancies herself as this)
** TheLancer: IF
** TheSmartGuy: Gust
** TheBigGuy: Nisa (again, Nepgear in Nisa's mind)
** TheChick: Compa
* ForcedTutorial: Did you expect Compile Heart to let you off the hook in a ''Neptunia'' game?
* FunWithAcronyms:
** ASIC, which stands for '''A'''rfoire '''S'''yndicate of '''I'''nternational '''C'''rime.
** SADOLSMD is '''S'''ecurity '''a'''nd '''D'''efense '''O'''rganization '''L'''eanbox '''S'''pecial '''M'''ission '''D'''epartment.
** In the English dub the organization's name is [=RRoD=], short for Regal Regiment of Defense.
* GiantMook: The Grandogoo.
* GottaKillThemAll: [[spoiler:The Conquest Ending route plot is this; you have to kill all the goddesses. It's disturbing, to say the least.]]
* GratuitousEnglish: The EndingTheme has quite a bit of it.
* HeadsIWinTailsYouLose:
** Even if you have your party pimped out with awesome equipment and doing fine against the first fight with CFW Magic, the game will still continue as if Nepgear and company are [[HopelessBossFight still getting owned by her.]]
** There's also the first battle against [[spoiler:a Killachine]]; even though the damn thing fades out via the standard enemy death animation, the party's dialogue goes on to reveal that it was too powerful for them.
* HammerSpace: "Don't ask where they hide their weapons."
* HotSpringsEpisode: What you will be rewarded when you get to Chapter 7. The trophy for this scene lampshades it.
* HungryWeapon: [[spoiler:The Malice sword, which grows more powerful as it consumes [[KillTheGod fallen CPUs]] until it becomes the Gehaburn. "Feeding" it and using the sword on Arfoire is the point of the Conquest Ending.]]
* InterfaceSpoiler: After beating the Underling for the first time, her respective {{Leitmotif}} will be unlocked in the music playlist in the museum. The name of said leitmotif is [[spoiler:Warechu]]'s Theme, which can spoil the fact that [[spoiler:Warechu]], a character that you meet a chapter later, is part of the ASIC despite his cutesy appearance. Well before the actual reveal.
* ItsAWonderfulFailure[=/=]KillEmAll: [[spoiler: The Conquest ending. See DarkestHour above and ShootTheShaggyDog.]]
* JigglePhysics: Vert and Compa, mainly.
* LethalLavaLand: Underverse is a dungeon found in a volcano, which is located south of Leanbox.
* MirrorMatch: The Coliseum includes some battles against copies of the playable characters. Some of these battles are unlocked through DLC.
* MoodWhiplash: Goes through it ''bad'' during the Conquest Ending. In between all the drama and [[spoiler:killing your friends and family to power up your weapon]], the battle dialogue stays the ''exact'' same. So now it seems like Neptune is unironically cracking jokes and trash talking [[spoiler:all her friends right before she kills them.]]
* MoralEventHorizon: In-universe. During the Conquest Ending path, the party considers [[spoiler:Underling having crossed it when she ambushed and fatally wounded an already-battle worn Vert]]. ''Nepgear'' of all people says, "I should have done this a long time ago," after [[spoiler:killing her once and for all]].
* {{Mordor}}: The Gamindustri Graveyard. Bonus points for the [[http://vignette1.wikia.nocookie.net/neptunia/images/9/9d/Hyperdimension-Neptunia-mk2_2011_04-21-11_013.png/revision/latest?cb=20120215041719 ominous tower with an eye on it]].
* MultipleEndings: There are a lot of them. ''[=Re;Birth2=]'' adds one more. This gives the game the most endings in the whole franchise with a total of [[UpToEleven nine endings]]!
* ObviousBeta: The [=DLCs=] fixed this though. Even without the DLC, ''mk2'' is still not as bad as its predecessor in terms of being an Obvious Beta.
* PantyFighter: Aside from a couple exceptions, every girl plays this trope straight.
* PantyShot: All over the place.
* ProductPlacement:
** One of Rom and Ram's staves outright state they're from Manga/CardcaptorSakura instead of the usual style of loosely describing it or using a fake, but similar sounding, name.
** Underling directly mentions the energy drink Powerthirst at one point.
** According to one of the Ramen Writer's Chirps, Noire's favorite kind of ramen is the microwaveable Cup Noodles from Nissin.
* RecursiveCanon: In one of her Chirps, Vert mentions requesting for ''Neptunia mk2'' to be released for "[[UsefulNotes/Xbox360 the Box]]."
* RedundantParody: The game was supposed to be a parody of serious [[EasternRPG JRPGs]] with wacky characters, but thanks to Nepgear being the protagonist it actually became one.
* RuleOfSymbolism: How the fans usually interpret the [[spoiler:Conquest Ending. Even if you end the UsefulNotes/ConsoleWars by having one Super Console that plays everything, piracy will always continue to exist. With only one super console, the industry will stall without competition. And a gaming world without competition will not improve and will fall apart sooner or later. It's even lampshaded by Deity of Sin Arfoire herself in that particular ending]].
* ScrappyMechanic: InUniverse. Vert plays with this trope in one of her bonus voice tracks...
--> ''"I don't know who it was. But whoever invented the fatigue system must be judged a world-class terrorist."''
* ScriptedBattle: Your first boss fight in this game is against CFW Judge, and even if you unload Nepgear's most powerful attack at that point against him, it will only do zero damage. In fact, even if you're at [[{{AbsurdlyHighLevelCap}} maximum level with the DLC]] and could {{One Hit Kill}} CFW Judge, you STILL do zero damage.
* SelfDeprecation: Keiji Inafune's cameo attacks. IF comments she only feels apathy from the sword form and remarks that she doesn't "want hipsters ironically enjoying [her] new attacks" and Nepgear herself comments that he's full of wrath and admits it's embarrassing to wield.
* ShootTheShaggyDog: [[spoiler:The Conquest Ending is implied to be this. Nepgear feeds the Malice Sword by killing ''all of the other [=CPUs=]'' with it, then destroys Arfoire with the fully powered sword. Arfoire, however, seems to take being defeated quite well, all things considered... The reason why is that, by having killed the other [=CPUs=], Nepgear has fated the world to have no competition, and therefore no progress. With no progress, Gamindustri will ultimately crumble, and Arfoire will then return to feast on the remains. The implications of this are that the [=CPUs=] all died, not to avert Gamindustri's end, but to make it inevitable. Thankfully, this is only one of Multiple Endings, so it is not strictly canon.]]
* ShoutOut: [[ShoutOut/{{Neptunia}} This series has its own page.]]
* SingleStrokeBattle: Done as an AntiFrustrationFeature. Attacking enemies before the battle begins will typically just give you a slight initiative bonus. Attacking [[GoddamnBats enemies weaker]] than you before the battle begins will instead instantly kill them, permitting you to quickly work your way toward any [[BossInMooksClothing Dangerous Species]] you may need for a quest or just to finish a FetchQuest.
* SwordOfPlotAdvancement: [[spoiler:The Magic Sword found only in the Conquest End.]] [[PlayerPunch Have fun obtaining it.]]
* TakeThat: It happens [[http://www.youtube.com/watch?v=KQ9Km7WW2aE here with the four goddesses arguments over consoles]].
** The Scout named [[http://vignette2.wikia.nocookie.net/neptunia/images/1/14/Misuo.png/revision/latest?cb=20140311200043 "Misuo"]] is a parody of the infamous [[TheScrappy Mist Rex]] from VideoGame/SuperRobotWarsK, and most of his lines are parodies of Mist's [[MemeticMutation horribly written dialogue]] from that game. Such as "This world isn't worth saving!" and "I'm used to suppressing riots."
* TurnsRed: Comes in a few different ways, the most common being Viral Monsters. This change happens randomly, but will [[TheCorruption occur more often if one enemy of that type has already changed during the fight]]. Certain monsters may also [[CannibalismSuperpower consume each other to reach this effect]], the earliest a player is likely to see is Horsebirds eating Radishers to become Horsebird Leaders, which are literally just red Horsebirds.
* TheWarOnStraw: Straw digital pirates.
* UnexplainedRecovery: The Planeptune Mascot's body was destroyed by Underling early on in the game, yet she appeared to be completely fine after the battle and later, we see her along with the other Mascots hanging out with Histoire and with her original form restored. It's really puzzling considering Lowee's Mascot also suffers the same fate and yet, she had to be repaired by the heroines with the help of the Oracle and Gust (Broccoli in [=Re;Birth2=]). Though it could've been justified by the Planeptune Mascot's part since the Lowee Mascot was already using most of her power to seal the Killachines away, while Planeptune's Mascot was just merely hanging out in the forest and therefore was not using her power at all. This could've allowed a full recovery on her own.
* UnsoundEffect: A few instances such as when Nepgear and co. beat up Underling for laying waste to Leanbox (Bitch slap!) and also when Underling thrashes Nepgear and Uni at LAN Castle. (Backhand! Stars and stripes!)

!! Tropes exclusive to ''[=Re;Birth2=]'':
* BrainwashedAndCrazy: In the Holy Sword ending, Nepgear discusses this trope when she suspects [[spoiler:the Gehaburn inflicted this on the goddesses to make them fight each other. Considering how quickly the team reconciled and came up with a better solution after breaking the sword, she might not be far off.]]
* ChuckCunninghamSyndrome: Just like ''[[VideoGame/HyperdimensionNeptuniaReBirth1 Re;Birth1]]'', Gust and Nisa are not present. They've been absent since ''Victory'' and were outright written out of the story here and in ''[=Re;Birth1=]''. However, 5pb. and RED return after having received this treatment previously.
* DiscOneNuke: The DLC swords can be used in the very first chapter and give Nepgear anywhere from 1600-2500 STR when she would normally have around 200.
* DubNameChange: Or rather, ''un''change. Pirachu gets his name swapped back to Warechu.
* LivingWeapon: Pippin from FairyFencerF appears in the game as a DLC sword, and is implied to be a sentient weapon.
* PlayEveryDay: Stella's ☆ Dungeon works on this principle. Each adventure she takes a certain amount of real-world time, which encourages checking up on her right as she finishes each time. Luckily, there's no penalty to not engaging with the feature apart from missing items that you can collect in other ways.
* SameContentDifferentRating: A case of rating lowering from the original M to a T. Even though the game is still the same (and actually has a CG of CFW Trick licking Rom and Ram ''added'') bar the voice acting. Meaning either the NISA inflated the rating because of the darker and edgier approach or the ESRB being more lenient.
* SelfDeprecation: A Chirper user you encounter is a kangaroo with Neptune's hairstyle, who only says "Jump!" and "I'm a kangaroo!", a playful jab at Neptune's actual jumping lines in ''VideoGame/HyperdimensionNeptuniaVictory''.
* SillinessSwitch: Several of the plans, like Brow Mania, which makes the characters' eyebrows show through their hair to match the character art.
* WakeUpCallBoss: [[spoiler:Rom and Ram. Both transformed]] and with some ridiculous stats to boot. Going in below level 16 makes the fight nearly impossible and level 23 and up is recommended for an even fight. It doesn't help that RED and Compa's defensive stats are quite low at this point in game.
