History VideoGame / HadesVanquish

The game's website can be found [[http://www.foxeye.squares.net/product/hadesvanquish/index.htm here]]. Both Japanese and English versions of the game can be purchased at Website/{{DLsite}}.

* EscapedFromHell: The main point of the game is to literally invoke this trope to Mana. Her death causes her to fall down to the underworld of Hades, and she must use different tools, upgrades, and her own strength to climb out of Hades and figure out how she died to begin with.
* EverythingsBetterWithPenguins: Small penguins exist in Hades, but they're apparently just containers of souls that just happen to be in the form of penguins that are capable of things a penguin can't normally do, such as {{Flight}} and [[SuperNotDrowningSkills breathing underwater]], something Mana [[LampshadeHanging lampshades]]. They run the shops that the player can find in villages and at random during dungeon crawls.

* LaserGuidedAmnesia: Mana's good with using her Flash Gun, but she doesn't know or remember why she has one on her after her original death. She overall doesn't remember much of anything that led to the cardiac arrest that killed her, [[EverythingsBetterWithPenguins but she can recognize a penguin]] when she sees one. [[spoiler:She also can't remember her best friend Yurina after she wakes up at the hospital, nor does she remember her suffering from the hypothermia that lead to her cardiac arrest. Getting all 4 special items allows her to recall more of her initial final moments with Yurina before her coma.]]

* TutorialLevel: One of Hades' residential [[EverythingsBetterWithPenguins penguins]] can bring the player to this at the very beginning. It can easily be skipped, though.

* EscapedFromHell: The main point of the game is to literally invoke this trope to Mana.

* IAteWhat: [[spoiler:In the game's GoldenEnding, Mana wanted some juice from Yurina, but Yurina accidentally gave her liquor, instead, only finding this out ''after'' Mana chugged a lot of the drink down. IntoxicationEnsues.]]

''Infinity UW Dungeon: Hades Vanquish'' is a {{Roguelike}} {{Platform|Game}} [[DoujinSoft doujin game]] by Creator/FoxEye (the developer behind ''VideoGame/{{Holdover}}'', ''VideoGame/SacrificeGirl'', and ''Sufferer''). It stars a girl named Mana, who has just recently died from cardiac arrest and has her soul sent to the Underworld of Hades.

* LuckilyMyShieldWillProtectMe: Before Mana can hurt each boss, she must shoot at their shields until they break, then kick them into an electric wall to damage them.

** Mana herself turns out to be guilty of this trope as well [[spoiler:in the game's GoldenEnding]]. [[spoiler:Being half-naked from the waist down for a sleepover was decidedly ''not'' a good idea [[RealityEnsues if it meant making your crotch, and later on your whole body, more susceptible to the cold to the point of getting a hypothermia-induced coma]]. Especially if you were drunk and restless beforehand. Mana's final speech of the entire game has her acknowledging this, herself.]]

* TheGhost: Subverted. While Yurina is seen and described on the game's website as Mana's best friend, she never makes an appearance in the game itself. There may be future plans to turn this around, however.

** [[spoiler:DoubleSubverted at the very end, where she finally appears to help Mana wake up from her supposed death at the hospital. The GoldenEnding also shows that Yurina was accidentally responsible for Mana's trip through Hades to begin with.]]

** Then the GoldenEnding reveals that [[spoiler:when Mana was still alive, she had her panties washed, but it was too late to wear them for Yurina's sleepover, so she used her long green dress to cover her naked underside. This carried over into her afterlife in Hades after she suffered from hypothermia following a bad night of accidentally getting drunk by Yurina.]]

* HundredPercentCompletion: Collecting all 4 special items in each village after the first one and then reaching the end of the game with them unlocks the GoldenEnding. In order to get them, however, you'll have to keep upgrading Mana's ability to run and jump in order to reach the platforms that bear them. However, that also means they will take up valuable slots in your limited BagOfHolding that you likely wanted for useful items and upgrades. [[spoiler:The fourth and final item specifically requires you to max out your run and jump skills for the first jump, and then throw away all of your jump skills in order to properly reach the item with your second jump without hitting the top of the screen.]]

* LaserGuidedAmnesia: Mana's good with using her Flash Gun, but she doesn't know or remember why she has one on her after her original death. She overall doesn't remember much of anything that led to the cardiac arrest that killed her, [[EverythingsBetterWithPenguins but she can recognize a penguin]] when she sees one. [[spoiler:She also can't remember her best friend Yurina after she wakes up at the hospital, nor does she remember her suffering from the hypothermia that lead to her cardiac arrest.]]

* NakedPeopleAreFunny: [[spoiler:The reason why Mana has a long green dress in Hades, but no underwear to go with it, is because before her death, she had no panties to wear for Yurina's sleepover and decided to hide this from her with the long length of the dress. After Yurina accidentally got Mana drunk and sent her to bed to relax, her drunkenness kept her from sleeping peacefully, eventually leading to Yurina [[AccidentalPervert accidentally]] stumbling upon an upside-down Mana who unknowingly flashed her entire drunk and naked body at her.]]

* {{Pixellation}}: [[spoiler:Mana's drunk, unconscious, and naked body is shown this way in the game's GoldenEnding when Yurina tells her about how she saw her out of bed [[GoingCommando and found out that she wasn't wearing any underwear at all]].]]

** [[spoiler:Mana entered Hades with a green, one-piece dress, no panties to go with the dress, and a Flash Gun. Two of the special items are a wet pair of panties and a video game controller. She wears the dress because she was hiding her lack of panties from Yurina for their sleepover, as they were washed and she forgot to pack them. The pistol-shaped Flash Gun and the video game controller represent how Mana was playing a video game at Yurina's house that required her to use a [[UsefulNotes/NintendoEntertainmentSystem Famicom Zapper-like]] gun controller.]]

* {{Fanservice}}: [[spoiler:Beat the game to receive a suggestive image of a naked Mana in the game's folder. Achieve the GoldenEnding to get a second pic of her and Yurina hugging each other in bikinis while ThankingTheViewer.]]

* UnderwaterBossBattle: The third boss is a large undead fish skeleton. Beating it will instead involve kicking it downward into an electrical floor instead of against an electrical wall.

If Mana is killed by monsters, or if she drowns underwater, she is sent back to the very beginning of the game at the first village regardless of how far she's traveled, and she loses all of the Crysta she gathered once she leaves that village. However, she keeps any items and upgrade she had when she died, and the player can use this to their advantage to improve her skills earlier on in the game than usual in order to make better progress to the end.

** The game's randomly-generated layouts are grid-based and comprised of blocks. Some blocks are hard to jump to because they could be right above Mana, and trying to just to them may just have the player hit her head under it, instead. As the game's TutorialLevel shows, the player can just hold the "Jump" key/button in order to make Mana do an auto-jump the moment she walks off the edge of a block, ensuring that she can reach the block right above her without seemingly jumping from the previous block too soon.
** Purchasable powerup items, such as the Concentration Skill, and the Highly Precise Bullet Skill, make it easier to collect Crysta by suppressing how explosively it all scatters about after respectively kicking or shooting an ore block open.

Mana's final speech of the entire game has her acknowledging this, herself.]]

* FinalBoss: [[spoiler: A large, completely black succubus with 5 hit points, 4 layers of shields, and homing blasts that she unleashes every time Mana breaks one of her shields. This is also a subversion, because while she is the last of the four guardians, beating her does not complete the game as there's still only two more dungeon floors left to traverse through]].
* {{Foreshadowing}}: Everything on Mana's person, alongside the 4 special items that need to be found to unlock the GoldenEnding, [[spoiler:represent fragments of her last few memories before she passed out and died.]]
** [[spoiler:Mana entered Hades with a green, one-piece dress, no panties to go with the the dress, and a Flash Gun. Two of the special items are a wet pair of panties and a video game controller. She wears the dress because she was hiding her lack of panties from Yurina for their sleepover, as they were washed and she forgot to pack them. The pistol-shaped Flash Gun and the video game controller represent how Mana was playing a video game at Yurina's house that required her to use a [[UsefulNotes/NintendoEntertainmentSystem Famicom Zapper-like]] gun controller.]]

** Unintentionally, that is. With Mana not wearing panties throughout the whole game, her green dress is literally the ''only'' article of clothing she's wearing when she's sent to the Underworld for the first time. She doesn't find out about this until a Hades' resident points it out to her, with him believing that it's a hobby or custom Mana followed, [[BigShutUp much to Mana's dismay and disgust.]] [[spoiler: She can eventually find her lost panties to hold on to as one of the four special items needed to unlock the GoldenEnding, but she can't actually wear them because they're soaking wet for some reason.]]

* HundredPercentCompletion: Collecting all 4 special items in each village after the first one and then reaching the end of the game with them unlocks the GoldenEnding. In order to get them, however, you'll have to keep upgrading Mana's ability to run and jump in order to reach the platforms that bare them.

[[spoiler:The fourth and final item specifically requires you to max out your run and jump skills for the first jump, and then throw away all of your jump skills in order to properly reach the item with your second jump without hitting the top of the screen.]]

** [[SignatureStyle It wouldn't be a Fox Eye game without one.]] In this game, it {{cap}}s itself with Mana's health, so how long she can hold her breath underwater depends on how much health she has left. Consequently, this means having to go for a deep swim at really low health is an [[{{Unwinnable}} unavoidable loss]] if she doesn't have any Potions to restore her health or any Elixirs to revive her to full health/oxygen after she drowns. Mana can buy upgrades to decrease the rate her breath drops, and upgrades that allow her to swim faster are at the cost of making her burn through her oxygen faster with each upgrade level. Eating Oxygen Candy replenishes Mana's oxygen underwater by 50% for the small ones and 100% for the bigger ones, but they each can only be used once. This can change into a LastChanceHitPoint, where Mana will struggle for air when her OxygenMeter is half-empty, and again when it's one-third empty. When it's completely empty, she'll resist drawing breath one more time, making the meter flash and turning it into this trope. By that point, you need to surface for air or use an Oxygen Candy quickly before the meter completely fades to black, to which Mana drowns right then and there.

* WakeUpCallBoss: The FinalBoss can be seen this way. [[spoiler:Think you could get in a good, firm position to destroy the previous bosses shields in place over and over again? This boss will fire homing blasts at you to prevent that strategy.]]

* TrialAndErrorGameplay: The game can impose this on you due to its randomized dungeons, especially [[DifficultySpike later on]], but as explained in CameBackStrong above, you're able to make up for it if you have the time and patience.

* DifficultySpike: By the third set of dungeon floors, the Bottom in the (River) Styx, the game becomes much harder due to the increased amount of time Mana will have to spend underwater to get through those floors. That, combined with the smaller amount of air pockets ([[HopeSpot if you're lucky to find any at all]]), makes not getting hit and maintaining the OxygenMeter a lot more crucial. A Hades resident even warns Mana before these floors that no ordinary human would be able to get through there without drowning. [[TheDeterminator You continue on anyway to prove him wrong.]]

* CuteClumsyGirl: Yurina, Mana's best friend. Her info on the game's website describes her as being very gentle, but also rather careless. [[spoiler:This gets [[DeconstructedTrope deconstructed]], however, as Yurina's carelessness is what led to Mana's death and subsequent trip through Hades to begin with.]] Artwork for Yurina also shows her bikini [[WardrobeMalfunction randomly malfunctioning and falling off]] [[http://www.foxeye.squares.net/cg/cg25_a.jpg during]] [[http://www.foxeye.squares.net/cg/cg25_b.jpg a]] [[http://www.foxeye.squares.net/cg/cg25_c.jpg deep]] [[http://www.foxeye.squares.net/cg/cg25_d.jpg swim]], and she almost drowns after having an OhCrap moment over it.

* GoingCommando: Unintentionally, that is. With Mana not wearing panties throughout the whole game, her green dress is literally the ''only'' article of clothing she's wearing when she's sent to the Underworld for the first time. She doesn't find out about this until a Hades' resident points it out to her, with him believing that it's a hobby or custom Mana followed, [[BigShutUp much to Mana's dismay and disgust.]] [[spoiler: She can eventually find her lost panties to hold on to as one of the four special items needed to unlock the GoldenEnding, but she can't actually wear them because they're soaking wet for some reason.]]

* AuthorAppeal: [[SignatureStyle As always from Fox Eye's games]], [[WordOfGod Fox's]] fondness for underwater exploration and drowning also thrive in this game. He even called the vocalizations Mana's voice actress used for her drowning noises and gasping for air "wonderful".

However, her life is restored just before passing through Hades' Gate of Abyss in its first village. With no recollection of her past memories, but armed with only a Flash Gun and a lantern, Mana refuses to accept her afterlife in Hades. So she must use these tools to brave through 30 randomized dungeon floors of catacombs and hostile monsters to escape from this hell, return back to life, and figure out the mystery of how she died to begin with.

''Infinity UW Dungeon: Hades Vanquish'' is a {{Roguelike}} {{Platform|Game}} [[DoujinSoft doujin game]] by Creator/FoxEye (the developer behind ''VideoGame/{{Holdover}}'', ''VideoGame/SacrificeGirl'', and ''Sufferer''). It stars a girl named Mana, who has just recently died from cardiac arrest and is sent to Underworld of Hades.

* GoodBadTranslation: The self-made English script is slightly more comprehensive compared to past Fox Eye games with this trope, but there's still quite a bit of {{Engrish}} to go around, especially in the ending.

* CycleOfHurting: A resident of Hades describes an "Infinite Hell" as a mortal constantly trying and failing to escape from Hades without getting killed and sent back to the Gate of Abyss' entrance. He leaves it to Mana to keep trying her hardest to make it out of Hades until she decides give in and accept her fate.

* OxygenMeter: [[SignatureStyle It wouldn't be a Fox Eye game without one.]] In this game, it {{cap}}s itself with Mana's health, so how long she can hold her breath underwater depends on how much health she has left. Consequently, this means having to go for a deep swim at really low health is an [[{{Unwinnable}} unavoidable loss]] if she doesn't have any Potions to restore her health or any Elixirs to revive her to full health/oxygen after she drowns. Mana can buy upgrades to decrease the rate her breath drops, and upgrades that allow her to swim upward faster are at the cost of making her burn through her oxygen faster with each upgrade level. Eating Oxygen Candy replenishes Mana's oxygen underwater by 50% for the small ones and 100% for the bigger ones, but they each can only be used once.

* RingMenu: This is used to refuel Mana's lantern, reload her Flash Gun, and gain access to the items in her [[BagOfHolding purse]].

* BagOfHolding: Or "Purse of Holding". This purse stores all of Mana's items and upgrades. Each purchasable upgrade to her purse adds another row of empty space her for to put more of them in. However, she'll never have enough open spaces for every item and upgrade in the game by the time she gets all of the purse upgrades, which is important when collecting the 4 special GoldenEnding items.

* NakedPeopleAreFunny: [[spoiler:The reason why Mana has a long green dress in Hades, but no underwear to go with it, is because before her death, she had no panties to wear for Yurina's sleepover and decided to hide this from her with the long length of the dress. After Yurina accidentally got Mana drunk and sent her to bed to relax, her drunkenness kept her from sleeping peacefully, eventually leading to Yurina [[AccidentalPervert accidentally]] stumbling upon a upside-down Mana who unknowingly flashed her entire drunk and naked body at her.]]

* GenkiGirl: Mana is said to be a spry girl who's really good on her legs. Which is likely the reason why one of her two attacks is to [[KickChick kick demons in the face]] and send them flying.

** [[spoiler:Mana entered Hades with a green, one-piece dress, no panties to go with them, and a Flash Gun. Two of the special items are a wet pair of panties and a video game controller.

** [[spoiler:The last of these items is a bottle of wine or liquor, which is was the last thing Mana had by accident before she passed out from her drunkenness.]]
