Video Game / Hyperdimension Neptunia mk2

4 Following

Hyperdimension Neptunia mk2 (Chōjigen Game Neptune mk2) is a Continuity Reboot to Hyperdimension Neptunia, and the second game of the Neptunia series.

The four goddesses and Nepgear are captured while trying to take down ASIC, a syndicate that worships Arfoire. 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 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 Game Gear and how the goddesses are based on the home consoles on the market and the unreleased Sega Neptune.

A remake for the PS Vita 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, Hyperdimension Neptunia Re;Birth1, this game also utilises the battle system from Victory in addition to 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 reworked voice acting, music and visuals. A port to the Nintendo Switch was released on May 23, 2024 in Japan. A digital Western release, originally slated for May 21, 2024, was cancelled for not complying with Nintendo's guidelines. However, a physical edition for the English-language version was published by EastAsiaSoft, and released in Asia on September 4, 2025. It was released on the PlayStation 4 on August 7, 2024 in Japan and internationally on October 28, 2025 for both physical and digital versions.

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; 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 13 of the same year.

Tropes in Hyperdimension Neptunia mk2:

• Adaptational Costume Change: Histoire resembles her Super Dimension counterpart from the original game but with several notable differences. She is slightly taller, her shoulders are exposed and her sleeves no longer extend past her hands, the patterns at the hem of her dress are altered, now has thigh-high stockings, wears a singular teal tie instead of a split one, wears a different hat, has altered accessories that hover near her arms, and her wings are more fairy-like instead of butterfly ones. Her tome is also larger and more blue.
• All Just a Dream: Noire and Kei both have dream sequences in which CFW Brave asks them for permission to marry Uni.
• Alternate Universe: Just about everything has changed outside of the central premise, from the world's structure to how the main characters met. Additionally, this Gamindustri is officially known as the Hyper Dimension, while the previous Gamindustri is known as the Super Dimension.
• Artistic License – Biology: 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.
• Beach Episode: 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.
• Beyond Redemption: During the Conquest Ending path, the party considers Linda irredeemable when she ambushes and fatally wounds an already battle-worn Vert. It got to a point that Nepgear, of all people, says "I should have done this a long time ago" after killing her once and for all.
• Bragging Rights Reward: Getting the accessory that allows you to break the damage limit. Why's that? You only get this accessory as a rare drop from beating the highest leveled enemy of this game.
• Calling Your Attacks: You can't name your combos this time out, but the characters are more prone to shouting their attack names.
• Creator Cameo: Keiji Inafune, a game designer best known for the Mega Man series of games, and a former employee at Capcom, appears as a weapon for Nepgear in one of her EXE drives.
• Continuity Reboot: Despite being the second entry in the series, mk2 serves as a reboot to the first game ^note  Which ended with the goddesses giving up their CPU powers after defeating Arfoire, and living a normal life as regular humans until their deaths. . Among the changes include the setting taking place in the Hyper Dimension rather than the Super Dimension, the landmasses of the four nations taking place on a mainland (with Leanbox being separated from the other nations) instead of being Floating Continents, three of the four nations (Lastation, Lowee, Leanbox) being redesigned with a more futuristic aesthetic to fit it's premise, and the CPUs being born from Share Energy and starting off as good friends, albeit vitriolic ones, instead of enemies who later become friends.
• Curb-Stomp Battle: The Downer Beginning features CFW Magic single-handedly decimating the four CPUs. She then looms over Purple Sister, who shouts that Gamindustri is doomed.
• Darker and Edgier: To the first game, to the point that it earned an M-rating upon its Western release. While the first game's tone was mellow and laid-back, it was still a fun-loving Affectionate Parody of the video game industry that revolved around the characters Breaking the Fourth Wall (especially Neptune herself). By contrast, mk2 begins with the CPUs being held captive by the game's villain, one of the major antagonists being an open pedophile, the monsters being more dangerous than before, and the Hyper Dimension Arfoire being a full-on Eldritch Abomination with little hints of humanity. The Conquest Ending takes this a step further, having one of the game's heroines, Nepgear, being forced to kill all of her friends and family by admission of the Gehaburn.
• Darkest Hour: The Conquest Ending for the entire cast. Nepgear is forced to 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.
• Dating Sim: The Lily system allows the player character to check each character's affection level to other characters they interact with, most notably Nepgear.
• Decided by One Vote: One side event has the CPUs holding an election to determine who is the most popular after Neptune and Nepgear put out an Idol Singer video that proves to be immensely popular. Underling then shows up just to mess with the whole thing, but is pressured into voting by the bickering goddesses. She ends up fleeing with the CPUs in pursuit.
• Downer Beginning: The game starts with the CPUs and Nepgear getting into a Curb-Stomp Battle against CFW Magic and then held captive in the Gamindustri Graveyard. The following narration reveals that the world is now largely dominated by ASIC, with 80% of worship going to Arfoire. Three years later, IF and Compa arrive with a Sharicite, but with what little power it has they're only able to rescue Nepgear, while barely escaping a Hopeless Boss Fight against CFW Judge.
  Narration: Well, basically, Gamindustri was pretty messed up, you guys.
• Downer Ending: The Conquest Ending has Nepgear being Forced into Evil after equipping the Gehaburn, and killing all of the people she spent most of the game befriending, including her sister. The route ends with Nepgear looking solemnly at Planeptune.
• Dub Name Change: To match with the similar treatment for the CPUs, any instances of "_____ the Hard" were changed to "CFW _____".
• Early-Installment Weirdness:
  • Although the combat system was different from the first game, it was still different from the one used in Victory and subsequent mainline games and remakes. Among the differences include the "AP" bar being visibly shown at the bottom, EXE Drives only being used as Finishing Moves, different names for some of the battle commands ^note Like "Retreat" being called "Escape", the "Earth" element being used in place of the "Thunder" element, HDD requiring the CPU to get at least 100 SP, rather than 20% SP, and the logos used for the Stats being different.
  • The cutscenes used 3D models instead of 2D pictures with Limited Animation; with the exceptions of Virtual Stars and Riders VS Dogoos, no game since then — be it mainline or spin-off — has had this kind of cutscene.
  • It is mentioned that civilians only know the CPUs in their goddess forms. Later games would show their human forms and names being public knowledge.
• Equipment Spoiler: Trailers and screenshots sure love showing off Nepgear's Magic Sword in which you can only obtain after finishing with the Conquest End and start a New Game Plus.
• Fighting Your Friend: In the Conquest Ending, Nepgear, Neptune and the Makers end up fighting the other goddesses.
• Fun with Acronyms:
  • ASIC, which stands for Arfoire Syndicate of International Crime.
  • SADOLSMD is Security and Defense Organization Leanbox Special Mission Department.
  • In the English dub the organization's name is RRoD, short for Regal Regiment of Defense.
• Gotta Kill Them All: The Conquest Ending route involves Nepgear being forced to kill all the goddesses.
• Gratuitous English: The Ending Theme, Go Love and Peace, is sung in English by the Japanese singer Ayane.
• Heads I Win, Tails You Lose: The first battle against 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.
• Hopeless Boss Fight:
  • The Downer Beginning is a EXE Drive tutorial against CFW Judge, who takes 0 damage from Purple Sister's Celestial Severance.
  • The first actual in-game battle against CFW Magic has her still effortlessly decimate the Candidates. While it is possible to beat her by pimping out the party, the game will still continue as if Nepgear and company are still getting owned by her.
• Hungry Weapon: The Malice sword, which grows more powerful as it consumes fallen CPUs until it becomes the Gehaburn. "Feeding" it and using the sword on Arfoire is the point of the Conquest Ending.
• Interface Spoiler: 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 Warechu's Theme, which can spoil the fact that Warechu, a character that you meet a chapter later, is part of the ASIC despite his cutesy appearance. Well before the actual reveal.
• It's a Wonderful Failure: The Conquest Ending. Should you feed the demon sword by killing all of the other CPUs with it and then destroy Arfoire, she actually takes her defeat very well, and because of that, with all the CPUs killed, Nepgear has faded the world to no competition, and soon Arfoire's ultimate revival will come and she will feed on the remains, and Gamindustri will soon crumble and be doomed to an eternity of destruction. Thankfully, this is only one of the Multiple Endings, but is by far the worst. Ironically, though, this is the hardest of the Multiple Endings to get. If you want some consolation, you do get to keep the sword in a New Game Plus.
• Jiggle Physics: Vert and Compa's boobs jiggle during gameplay.
• Lethal Lava Land: Underverse is a dungeon found in a volcano, which is located south of Leanbox.
• MacGuffin: The Mascot Discs collected throughout Chapter 2, which Nepgear is tasked with collecting to gain their power, and the villains try to destroy them to prevent that. The Mascots give Nepgear a powerup right before the rematch with CFW Judge, allowing her to turn the tables and obliterate him.
• Mirror Match: The Coliseum includes some battles against copies of the playable characters. Some of these battles are unlocked through DLC.
• Mood Whiplash: During the Conquest Ending, the otherwise casual battle dialogue remains the same, even with all the drama and the killing your friends and family to power up your weapon thing. A glaring example is Neptune, who still cracks jokes and trash talks all her friends right before she kills them .
• Mordor: The Gamindustri Graveyard lives ups to its name of a graveyard where all games go to dies. Bonus points for the ominous tower with an eye on it.
• Multiple Endings: 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 nine endings!
• New Powers as the Plot Demands: When the White Disc/Lowee Mascot gets a duplication ability like the Black Disc/Lastation Mascot:
  IF: Hey... In Lastation, we got a bit of the Mascot's power, even though it stayed behind, so how about it?
  White Disc: Unfortunately, I lack the proper technique to perform such a...huh?
  [...]
  Broccoli: Patchwork with genetic materials may cause some glitches in the disc, but this glitch is cool, nyu.
  IF: So, like... The Mascot made a clone of itself just in case its physical body got destroyed?
  Broccoli: I guess we can go with that, nyu.
• No Body Left Behind: When sacrificed to the Gehaburn, the bodies for the CPUs immediately disappear after being killed.
• Optional Boss: Tons in the coliseum, the hardest of them being Delphinus.
• Panty Fighter: Aside from a couple exceptions, the playable female characters often have their undergarments exposed during gameplay.
• Product Placement:
  • One of Rom and Ram's staves outright state they're from Cardcaptor Sakura 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.
• Recursive Canon: In one of her Chirps, Vert mentions requesting for Neptunia mk2 to be released for "the Box."
• Redundant Parody: The game was supposed to be a parody of serious JRPGs with wacky characters, but thanks to Nepgear being the protagonist it actually became one.
• Rule of Symbolism: The Conquest Ending can be interpreted as such. Ending the Console Wars by turning one of its companies into a monopoly is a horrible idea. Piracy will always continue to exist despite any effort to crack down on it. A monopolistic 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.
• Scrappy Mechanic: In-Universe. 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."''
• Scripted Battle: 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 maximum level with the DLC and could One-Hit Kill CFW Judge, you STILL do zero damage.
• Secret Expanded Epilogue: There's 5 extensions for the Normal Ending, depending on each nation's Share amount and Nepgear's Lily Rank with other characters. Each extension has Nepgear hanging out with different characters, whether the Makers, her sister Neptune, or the CPUs/Candidates of another nation.
• Sequel Number Snarl: The "mk2" in its title would indicate that this game is a sequel to the first game. In actuality, it's a Continuity Reboot taking place in an Alternate Universe with little ties to the previous game's Super Dimension universe.
• Self-Deprecation: 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.
• Shoot the Shaggy Dog: The Conquest Ending is implied to be this. Nepgear feeds the Gehaburn 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.
• Shout-Out: This series has its own page.
• Single-Stroke Battle: Done as an Anti-Frustration Feature. Attacking enemies before the battle begins will typically just give you a slight initiative bonus. Attacking enemies weaker than you before the battle begins will instead instantly kill them, permitting you to quickly work your way toward any Dangerous Species you may need for a quest or just to finish a Fetch Quest.
• Take That!: The Scout named "Misuo" is a parody of the infamous Mist Rex from Super Robot Wars K, and most of his lines are parodies of Mist's horribly written dialogue from that game. Such as "This world isn't worth saving!" and "I'm used to suppressing riots."
• Turns Red: Comes in a few different ways, the most common being Viral Monsters. This change happens randomly, but will occur more often if one enemy of that type has already changed during the fight. Certain monsters may also 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.
• Unexplained Recovery: 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.
• Unsound Effect: 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!)
• Which Me?: After White Disc clones herself, accidentally, via New Powers as the Plot Demands, and is just called "White Disc" for both instances, but we'll note them here:
  White Disc (Original): This is me?
  White Disc (Original): How did this happen?
  White Disc (Clone): I wish I could tell you, me.
  White Disc (Clone): So you don't know either?
  Compa: I'm soooo confused right now!

Tropes exclusive to Re;Birth2:

• Brainwashed and Crazy: In the Holy Sword ending, Nepgear discusses this trope when she suspects 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 the Gehaburn's destruction, she might not be far off.
• Bribing Your Way to Victory:
  • The Babysitter's Club DLC adds Chibi IF and Compa to the party, who are far more powerful than their adult counterparts.
  • The Shares Quest DLC adds quests to fight Fake CPUs which award a high amount of Shares. Additionally, the Fake Purple Heart fight gives 1,024 MB and is repeatable, allowing the player to farm the Remake System without resorting to New Game Plus.
  • Histy's Rescue Plans DLC adds the following plans: Super EXP Up (applies a 6x experience multiplier, which stacks with the non-DLC EXP Up plan), Felis Insurance (lose no equipment if Stella's☆Dungeon fails), and Felis Express (halves the amount of time to complete a Stella's☆Dungeon run).
• The Cameo: Chibi (Ultra) IF and Compa, and Uzume are featured as DLC characters, but they have zero story sections.
• Chuck Cunningham Syndrome: Just like 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.
• Disc-One Nuke: 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.
• Ditching the Dub Names: When Idea Factory International got the rights from NIS America to localize their games, Pirachu was changed back into his original Japanese name, Warechu.
• Living Weapon: Pippin from Fairy Fencer F appears in the game as a DLC sword, and is implied to be a sentient weapon.
• Play Every Day: 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.
• Self-Deprecation: 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 Hyperdimension Neptunia Victory.
• Silliness Switch: Several of the plans, like Brow Mania, which makes the characters' eyebrows show through their hair to match the character art.
• Suspiciously Similar Substitute:
  • Inverted with RED replacing Nisa, as the two characters are noticeably different in looks and personality.
  • Downplayed with Broccoli replacing Gust, as the two look physically very similar but have different personalities nonetheless.
• Wake-Up Call Boss: 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.
