''Soul Sacrifice'' is a video game developed by Marvelous AQL and Japan Studio for the PlayStationVita. The concept was created by Creator/KeijiInafune, best known for being the co-designer for the ''VideoGame/MegaMan'' franchise.

''Soul Sacrifice'' is played in the third-person perspective. The player character is a slave that serves a powerful and cruel sorcerer. Just before the protagonist is going to be sacrificed, a demon in the form of a book appears before him. The book is a collection of stories that describe past fights between monsters and the powerful sorcerer. The player character is able to enter the book's world and experience the fights, thereby gaining experience and power. One particularly notable mechanic is the ability to sacrifice parts of the character's body or items to create devastating attacks. These sacrifices will be permanently marked on the player character's body, meaning that unless a slow-regaining resource is spent, they are not an infinite resource that can be tapped into.

The game was released in Japan on March 7, 2013, while the North American and European versions hit stores on April 30, 2013 and May 1, 2013 respectively.

A combination sequel-UpdatedRerelease, ''Soul Sacrifice Delta'', released in Japan on March 6, 2014, and in the US and EU on the Playstation Network on May 13 and 14 of 2014, respectively. It will receive overhauled graphics, systems, and AI. There will be an enhanced focus on co-op play, a number of new spells, more areas, monsters, and archfiends based on [[Creator/TheBrothersGrimm the Grimm Fairy Tales]]. Players will be able to choose between the two old factions and the third new one: Avalon, {{Knight Templar}}s who seek to destroy all monsters, no exceptions; Sanctuarium, a splinter group of sorcerers who believe that monsters can and should be saved; and the new faction the Order of Grim, a cult started by a sorcerer who noticed the EternalRecurrence of the Twin Gods' feud and who's followers bring hope to both sorcerers and non-sorcerers alike, in hope of somehow ending the vicious cycle. Which organization the player chooses to join will change what mission rewards and types of magic they can gain.

----
!! This game contains examples of:
* [[spoiler:AGlitchInTheMatrix: The sheer existence of the Grim faction is one, since ''nobody'' was supposed to notice the Twin Gods' Feud and the EternalRecurrence.]]
* ArcWords: "This is where your story begins."
* [[spoiler:AfterTheEnd: "Several Years Later" reveals that the world suffered a disastrous cataclysm 13 days after the Sorcerer you play as in the Phantom Quests became Magusar's partner, and the now-insane Magusar came to rule what remains of the world.]]
* AllJustADream: If you lose to Magusar after challenging him, the battle is immediately {{retcon}}ned to being another story from the diary.
** [[spoiler:If you've finished the original ''Soul Sacrifice'', transferring your save file to ''Delta'' reveals that the final battle from the original was all a dream, with Librom wondering what you are talking about.]]
* AllThereInTheManual: The Lore section of Librom, containing backstories of Archfiends and levels, or a rundown of how certain enemies came to be.
* [[spoiler:AndThenJohnWasAZombie: In two of the endings, depending on whether you choose to sacrifice or save Magusar in the final battle, you will either become the new Magusar or the new Librom.]]
* ArtifactOfDoom: [[spoiler:The grail, which also doubles as a JerkassGenie and, arguably, the BiggerBad for a majority of what all has happened.]]
* AxCrazy: Sortiara [[spoiler:ends up being a {{Deconstruction}}.]]
* BecomingTheMask: When sorcerers sacrifice monsters, they absorb the souls of those monsters. In process, they also gain emotions and memories of those whom they sacrificed. As a result, sorcerers start losing their sense of self.
* BeingGoodSucks: You're told outright from the very beginning that Avalon considers the Rite of Salvation to be an act of heresy, and those who use it too much risk suffering "serious consequences". These consequences include reduced quest rewards, getting yourself crippled while simultaneously giving the boss a free power up, and, eventually, [[spoiler:pissed off bounty hunters]].
** From a gameplay perspective, being good (saving more than sacrificing) makes you tougher and harder to kill, but your attack power will suffer and fights will take longer and longer to finish, so if you find yourself with a Divine arm you're probably a glutton for punishment.
** Being neutral is also pretty hard, since your levels have to be exactly the same in order to have a "neutral arm", and the Grimm faction gives out quest rewards at random.
* BeingEvilSucks: On the other hand, people who sacrifice someone/something they cherished in order to obtain what they want often realize too late that making DealWithTheDevil never ends well. Even sorcerers who sacrifice monsters ultimately succumb to all the souls they absorbed while hunting for monsters, which leads to transformation into the very monsters they fight and execution by other sorcerers.
* BigBad: [[spoiler:Magusar for the single player campaign]].
* BiggerBad: The younger of the two Gods who created the setting's world. While the older believes in order, the other likes chaos and greed, and that's why he created the chalice and gave sorcery to his people (the druids). [[spoiler: And that's why the world is in a constant state of destruction and restoration, because he engineered for an especially greedy individual to destroy the world.... the ''same person who was chosen by the other god to be devoid of greed and be able to save it.'']]
** [[spoiler: Finally able to be faced. In the original game, you only got a free DLC that let you face the two in a pair of Forgotten Pacts. ''Delta'' lets you fight God-Magusar, who is possessed by the Twin Gods, as the TrueFinalBoss.]]
* BlackMagic: Pretty much all magic is bad news, since it turns man and beast into monsters. Unfortunately, only a sorcerer can kill a monster, so there's a catch-22 for cleaning up all this magical contamination.
* BloodMagic[=/=]BloodyMurder: One of the possible offensive magics, available in two flavors: the blood spray or a melee claw flurry. While these are powerful, they are CastFromHitpoints, meaning you have to watch out for your health.
* BloodKnight: The Valkyrie constantly seeks out Sorcerers to fight, believing that each victory she achieves will bring her closer to her dead father.
** The Dullahan was one both in life and as an Archfiend. The man was a CombatSadomasochist who built up a rather fearsome reputation for actively directing his opponents to ''always'' wound him, even making sure they never hit him fatally. It got to the point that he wore chains during his fights, and eventually ordered his footmen to ''torture him for his own pleasure'' during his off-time.
* BodyHorror: The way you use magic practically revolves around this.
** Chaos mode is particularly nasty.
** The way that some monsters and Archfiends are created.
* BonusBoss: While it's not exactly harder than, say [[spoiler:Double Illecebra]], the Leviathan you see in tutorial can only be encountered in the tenth Avalon pact's group, where all combats are extremely hard.
* BossBanter: Some Archfiends and [[spoiler:Bounty Hunters]] engage in this, though in the case of the Archfiends, they speak in garbled gibberish that's translated in the subtitles.
* BreakableWeapons: A strange example. Since the only things that can be equipped are spells, it's possible to "break" your spells. Though it must be noted that story-wise the objects that break are not the spells themselves but the offerings that lets the sorcerer wield them.
* [[spoiler:ButThouMust: You '''must''' sacrifice Nimue/Sortiara when you face her. Attempting to save her will bring her back and make the fight against her continue. This is also true of the assassins sent after you for saving Archfiends. In both cases, however, you ''need'' to save them the first time if you want to get their Life soul.]]
* CallAPegasusAHippogriff: Standard monster names, decidedly NON-standard designs and origins. Goblins are giant rats made up out of other, smaller rats. "Orcs" are housecats mutated by magic into horrible blobby cannibalistic things with gaping mouths full of human skulls. Kobolds are trees that are transformed by residual magic. Ghouls are crows who fed on the corpses of sorcerers until the magic made them just as intelligent as humans, even creating their own society.
** ''Soul Sacrifice Delta'' introduces fairies, which were bees infected with magic, gaining self awareness and had overthrown their queen. Also introduced are gnomes (hares that have been horrifically mutated by magic, gaining the ability to merge with the ground and attack with giant ear hands) and orichalcum (snails who have gained a sense of self through magic, and had their shells transformed into treasure chests).
* CosmicPlaything: [[spoiler:What the chosen saviors amount to. The older god chooses a person completely devoid of greed, then that sorcerer is forced to face the apocalypse caused by a crazed magician. The sorcerer wins and sacrifices the magician to restore the world... ''in that point becoming tainted with the same curse that causes the previous end of the world''. With luck they may fight the greed that consumes them since their victory, and avoiding losing their very identity, but even if they'd be able to win against it, it'd only mean than another crazier sorcerer would take their place, forcing for a new savior to come and repeat the process.]]
* CrapsackWorld: It goes without saying.
* CrueltyIsTheOnlyOption: Most of the Avalon Pact sections have quests that are ''only'' available if you Sacrifice the segment's first Archfiend, as well as quests only available if you save it. Thus, if you're fully committed to one or the other, you'll have to go against your morals at least once in order to fully complete the Pact segment.
* DangerousForbiddenTechnique: Black Rites, which allow the sorcerer to sacrifice part of their ''bodies'' to gain great power; in game terms, you get a significant effect, but then your stats take a serious hit until you undo the Rite with lacrima. For example, the first one you gain access to lets you summon a massive burst of flame that deals serious fire damage to everything on the field, but in return you have to give up your skin (the fire bursts ''out of you'', causing severe burns and cutting your defense in half).
* DeadpanSnarker: Librom.
* DealWithTheDevil: Many of the backstories of levels and Archfiends within Librom involve this, with people sacrificing something of theirs to get what they desire. Suffice to say, they [[ShootTheShaggyDog don't end well.]]
* DeathSeeker: Centaurs.
* DownloadableContent: Is available. Announced content so far is the Japanese audio tracks (US/EU only), around 10+ free Archfiend battles, additional Black Rites, occasional codes for more spells, and paid episodes.
* DubNameChange: The Japanese version makes whole references to the Arthurian mythos, while the US/EU English versions have the references veiled due to some areas of Europe still treating the mythos as SeriousBusiness. Hence the changing of the names of the depicted characters from the Arthurian mythos in the English versions.
* ElementalRockPaperScissors: [[KillItWithIce Ice]] beats [[KillItWithFire fire]], which is effective against [[GreenThumb venom]] who beats [[DishingOutDirt stone]], which in turn curbstomps [[ShockAndAwe lightning]] who finishes the circle by cracking the [[KillItWithIce ice]].
* {{Expy}}: Librom is one to [[VideoGame/{{NieR}} Grimoire Weiss]].
** Also, [[spoiler:the grail]] functions similarly to [[Manga/{{Berserk}} behelits]] in that [[spoiler:it appears before the mortals who are in the state of total despair and grants their wish for a horrible price]].
* EyesDoNotBelongThere: Even by the BodyHorror standards of the game, Magusar's arm is particularly nasty, with so many eyes... and that's before the end of the world.
* FlunkyBoss: Most bosses summon goblins at some point during their fight so you have something to save/sacrifice during the battle to recharge your offerings.
* FusionDance: Done in rather grotesque fashion as many monsters are amalgam of beasts and men.
* {{Greed}}: Arguably one of the main reasons why the world has become so dark. Orcs and other monsters turn to devouring sorcerers just to further increase their power, a human will make a DealWithTheDevil and end up an Archfiend... it also plays an important part in the legend of how the world was formed.
* GodAndSatanAreBothJerks: Technically a spoiler, but given that both the "good" and "evil" gods appear as DLC bonus bosses, and the state of the world, it'd be more surprising if it ''wasn't'' true.
* HeWhoFightsMonsters: Pretty much all sorcerers in general. Sooner or later, all sorcerers succumb to all the souls of monsters they absorbed and transform into monsters themselves.
* IAmAHumanitarian: Notably exemplified by Harpy although there are other monsters who indulge in this as well.
* IJustWantToBeNormal: Unsurprisingly, Magusar isn't really happy to be immortal while being forced to sacrifice monsters non-stop to fuel that very immortality.
* ImprobableWeaponUser: The protagonist, who uses his own body parts as weapons.
* InsistentTerminology: Librom is quick to remind you that the Lachrima are ''[[BerserkButton not]]'' his tears. So stop asking if they are.
* JerkWithAHeartOfGold: ''[[TheScrooge Carnatux]]'', of all people, turns out to be one towards the end of his quest chain.
* KnightTemplar: The sorcerers of Avalon must follow one rule: All monsters must be slain. They're willing to turn a blind eye to the occasional saved target. But for those who consistently save monsters, well, see NoGoodDeedGoesUnpunished below...
* LimitBreak: At low health, you can perform ultimate sacrificial spells called Black Rites. While they are powerful, they have negative side effects that do not go away until you fix them with Librom's tears.
* MagicalSociety: The Secret Sect Avalon, a sorcerers' guild whose members are the descendants of surviving Druids.
* MedievalEuropeanFantasy: Noteworthy as the game's world is essentially an alternative version of the King Arthur mythos and appropriately includes...
** NamedAfterSomebodyFamous: ...adaptation versions of Nimue, Merlin, Morgan le Fay, Lancelot, Percival, and Gawain.
* MultipleEndings: Three in the original game, five in ''Delta''.
** The original three. In ''Delta'', you can only get these endings if you avoided completing certain quests.
*** If you [[spoiler:defeat Magusar before finishing all the main story chapters in Librom, the game ends immediately after Magusar's defeat, with the protagonist musing about how his/her actions have saved himself/herself, but the future of the world is still uncertain.]]
*** If you [[spoiler:complete all the main story chapters and choose to ''sacrifice'' Magusar in the final battle, then the grail fulfills your wish and returns the world to its original form, however the protagonist is left with the curse of Magusar and his right arm, unsure of what the future holds for him or the world but still believing that hope can change it for the better.]]
*** If you [[spoiler:complete all the main story chapters and choose to ''save'' Magusar, the protagonist begin a cycle of defeating and saving Magusar over an over, while line between the protagonist and Librom becomes blurred and they become one. They fight with Magusar for years until the protagonists body breaks down and can no longer fight. Like the original Librom, they sacrifice their body to become a book that will pass on both their story and Librom's tale to the next prisoner that can take on Magusar.]]
** The two added in ''Delta'', which require you to [[spoiler: complete a certain series of quests, unlocking the TrueFinalBoss: the God-Dragon, Magusar possessed by the Twin Gods and turned into a tyrant.]]
*** If you [[spoiler: choose to save God-Magusar, the wills of the Twin Gods are destroyed and Magusar still holds their power. He becomes a benevolent guardian deity of humanity, watching over them to help combat the madness to come.]]
*** If you [[spoiler: choose to sacrifice God-Magusar, the wills of the Twin Gods are destroyed and the protagonist achieves apotheosis. Magusar and Librom have a heart-to-heart over what will become of the world.]]
* MyGodWhatHaveIDone: The histories of areas and Archfiends have cases of this.
* {{Mythology}}: The world of ''Soul Sacrifice'' contains many references to numerous mythologies, even telling alternate versions of certain stories.
** KingArthur: A number of (renamed) characters from the Arthurian mythos, Avalon and Camelot, and the Holy Grail appear. Excalibur is even one of the Black Rites.
** ClassicalMythology: The war that tore apart the world was called the Olympian War, the tribe of humans born without magic are called the Romalus, there are numerous areas named after things from the mythos: the Plains of Olympia, the Catacombs of Pandora, the Ruins of Tartarus where the Cerberus dwells, Mount Helios, the Icarus Pasture, the Poseidon Inn, Lake Andromeda. Gorgon and Vulcan are Black Rites.
** Literature/TheBible: The city of Babylon, Noah's Desert, the fallen kingdom and Archfiend both know as Leviathan, the Caverns of Goliath.
** NorseMythology: There is the Valhalla Abbey, a Valkyrie is an Archfiend, and Gleipnir is a Black Rite. ''Delta'' reveals that the founder of the Sorcerers' Guild became a monster which they named Odin.
* NoGoodDeedGoesUnpunished: [[spoiler:If you primarily save the bosses instead of killing them, you'll eventually start encountering vigilantes hired by Avalon, who are not happy with you saving so many monsters.]]
* OldSaveBonus: Importing a save file from the demo adds the Spirits' Heart spell.
** You can import your save from the original ''Soul Sacrifice'' into ''Delta''.
* OneWingedAngel: [[spoiler:Magusar. After you defeat his human form, he turns into a gigantic dragon.]]
** [[spoiler:OurDragonsAreDifferent: It is not so much a dragon as it is a dragon-shaped mountain of bone and corpses.]]
* OurMonstersAreWeird: Dear lord...
* PowerIncontinence: In the setting, this often happens to magicians who get consumed by the souls of monsters they absorbed. Thankfully, this doesn't happen in-game.
* PowerAtAPrice: Almost all monsters, especially ones who [[WasOnceAMan were once humans]], sacrificed something/someone they cherished in order to be granted a tremendous power.
* PowerUpgradingDeformation: The creation of monsters in a nutshell, to put it mildly.
* PreOrderBonus: Quite the list: two exclusive costumes (one male, one female) and three exclusive magic spells (Spirits' Flamespike, Spirits' Blightstone, and Spirits' Fulgurwood). It also includes the Japanese audio for free.
** Buying ''Delta'' within the first four weeks of release grants you a number of unique costumes.
* PressXToDie: You can actually go right to the FinalBoss at the very beginning of the game, which ends [[TotalPartyKill about as well as you'd expect]].
* PublicDomainArtifact: [[spoiler:The Holy Grail appears as a sentient entity who appears to humans [[DespairEventHorizon who are at their lowest]], promising to grant their deepest desire in return for "an offering". In reality, however, it ends up turning the human into an Archfiend.]]
* RedRightHand: A sorcerer's right arm become corrupted by "the blight" due to the magic they wield. It gets worse the more they sacrifice monsters and better the more they save them.
* RelationshipValues: Allies have an Affinity bar that rises with the more quests you complete alongside them. In addition to this, Allies with Divine or Dark arms can actually lose affinity if you save (Dark) or sacrifice (Divine) an Archfiend while they're with you, and if you do this too many times, that Ally will become "Separated" from you, preventing you from using him/her. Allies with Neutral arms don't care whether you save or sacrifice Archfiends.
** In Delta, with the introduction of Grim, now you have to keep to the ideas of the Faction to gain Relationship points and not piss them off. This is used due to the fact that some Neutral Arm characters (such as Magusar, Radux and Sortiara) do not approve of you saving Archfiends, despite them usually uncaring about your choices.
* {{Retcon}}: This is actually a game mechanic. By using Lacrima, you're able to alter certain events and aspects the journal, which include undoing the status buffs caused by Black Rites and resurrecting fallen Allies.
* TheReveal: [[spoiler:The author of Librom is Librom himself.]]
* SceneryGorn
* SevenDeadlySins: Most boss monsters are categorized this way based on what sins they most indulged in before turning into monsters. There is an eighth category known as the Desperate, who represent the strength of will (Jack-o'-Lanterns and Jack Frosts) and madness (Unicorn and Phoenix) that people go through during life.
* SlidingScaleOfIdealismVersusCynicism: The game starts ''very'' deeply in the cynical end of the scale, and then little by little, notions like companionship, friendship, and especially hope, make their way into the plot, finally becoming a powerful force by the ending. While the game doesn't get really idealistic, those tones lessen the grimness of the setting.
* [[spoiler:StableTimeLoop: Heavily implied in the ending.]]
* SummonMagic: Golems.
* SwissArmyTears: The game's currency.
* TogetherInDeath: Illecebra's goal is to die with Magusar. [[spoiler: Later Librom and Magusar are united like this in the sacrifice ending.]]
* VideoGameCrueltyPotential: One of the biggest aspects of the game is sacrificing your comrades in battle. It may be a [[SubvertedTrope subversion]] however. While sacrificing your comrade will take him out of the fight, it will not only give you a very powerful attack spawned from his sacrificed carcass, but at the end, he'll get bonus rewards for being sacrificed, so it's a win-win situation.
** Monsters may be "saved" or "sacrificed" when you get them near death. Saving them turns them back to a normal creature (a housecat, a civilian, whatever), it heals you and boosts your defense. Sacrificing them increases your attack power and recharges your offensive spells. Leaning too heavily on one or the other is a potentially powerful strategy that could really unbalance you if you're not careful.
*** As of Delta, you need to do your faction's favoured action (save for Sanctuarium, sacrifice for Avalon and fate for Grim) to recharge your offerings.
*** "Saved" boss monsters unlock AI-controlled [=NPC=] comrades for the single-player version of the campaign.
** You can also tip Librom over by tapping at him. He'll then get up and make a few snarky comments.
* VideogameCrueltyPunishment: Actually this trope could be ''inverted'' since the game constantly punishes moral choices, while giving easier outcomes and rewards to those who choose selfishly (in the vanilla game; Avalon-affiliated players still gain points by sacrificing). In one boss battle, choosing to save your enemy will not only drag the battle, but ''drain half of your current health on the spot, giving it to your enemy.''
** Multiplayer isn't much better, if you save a team-mate, half of your health goes away to heal him. If you choose to sacrifice him instead? Your spells get a nice recharge, and a very powerful attack erupts from the sacrificed, instakilling all normal enemies and harming quite a bit the bosses. If you have a lot of life levels, even the reward for saving enemies will be much less interesting than sacrificing them. A bit of healing? At that point your healing skills will do a ''lot'' more in one go.
* VideoGameCaringPotential: In Delta, players who joined Sanctuarium gain points by saving monsters. Not only that, but saving common fiends such as orcs and gnomes refresh your offerings (sacrificing them boosts your damage while letting fate decide speeds you up). You can even gain points by ''being saved by a fellow sorcerer, which also benefits him if he's on the same faction''.
* VoiceOfTheLegion: The narrator of the diary speaks with both a male and female voice simultaneously. Librom does the same in the Japanese voice track, but only has a single, male voice in the English one.
* WasOnceAMan: The backstories of many bosses in this game start out that way.
* WeirdCurrency: The book occasionally cries moisture from its eye, and wiping away the tears is how you get your currency. It insists they're not tears, and calls them "''[[GratuitousLatin lacrima ]]''," but that's just a fancy word that means "tears" anyway.
* WhamLine: The Postscript.
-->[[spoiler:My name is Geoffery ''Librom''.]]
* XMeetsY: ''VideoGame/MonsterHunter'' meets ''VideoGame/DemonsSouls''/''VideoGame/DarkSouls''.
** With a little bit of ''VideoGame/PhantomDust'' thrown in.
* YourSoulIsMine: When you sacrifice monsters, this is essentially what you do.
