A MassiveMultiplayerCrossover StrategyRPG featuring characters from designers Creator/IdeaFactory, Aruze, Creator/RedEntertainment and Creator/{{Atlus}}. It has an excellent combat system and features appearances by many interesting and [[CultClassic beloved]] characters, but [[NeverLiveItDown all anyone ever talks about]] is the [[BlindIdiotTranslation ridiculously poor localization]].

Should not be confused with ''ComicBook/ChaosWar'', a 2011 Creator/MarvelComics CrisisCrossover.

There are lots of characters to choose from, and they all range from a variety of games:
* Creator/IdeaFactory
** ''Spectral Tower''[[note]]Technically the first ''Spectral'' game, meaning the ''Spectral Force'' series and its children series should be under it, but GenreShift and SequelDisplacement puts ''Force'' as the face of the Neverland games.[[/note]]
** ''Spectral Force''
*** ''Spectral Blade''
*** ''Generation Of Chaos''
*** ''VideoGame/SpectralSouls''
*** ''[[VideoGame/BlazingSoulsAccelate Blazing Souls]]''
** ''Steady × Study''
** ''Rebirth Moon'' (also the game whose engine was modified for use in this game)
** ''Mars of Destruction''
* Aruze
** ''VideoGame/ShadowHearts''
* Creator/{{Atlus}}
** ''VideoGame/{{Growlanser}}''
* Creator/RedEntertainment
** ''[[VideoGame/{{Gungrave}} Gungrave: Overdose]]''
** ''Shinsengumi Gunrouden'' (a.k.a. ''Code of the Samurai'')
* ASCII Media Works
** ''Dengeki Playstation'' (a gaming magazine)

The story opens with three {{Ordinary High School Student}}s--the sourpuss Hyōma, the hyperactive Shizuku, and the cowardly Hayatemaru. They agreed to ditch school one day to investigate a strange cave that is said to hold mystical power. The story goes that if one prays there, his/her wish will be granted. However, when they reach said cave, something bizarre happens and they are sucked into a parallel dimension: a world called "Endia" ("the end of all worlds"). Endia is composed of a ring of islands, and oddly, has a sun that never sets. Hyōma is separated from his friends and encounters a purple-haired girl named Rin Sunroad. Rin is a "Gate Master"--she can operate special terminals that allow the transport of goods and even people. She tells him that he is a "Knight" (a person who is usually pulled from another world). Hyōma finds his friends early enough and must now gather an army of fellow Knights, and take part in a race to find the Keys, which may be the vital items that allows everyone to return to their own worlds--or even new Knights to join Hyōma's and Rin's cause.

Has a SpiritualSequel of sorts in ''VideoGame/CrossEdge'', another MassiveMultiplayerCrossover involving Idea Factory with a TrappedInAnotherWorld premise. [[VideoGame/BlazingSoulsAccelate Zelos]] and Meu appear in both games.

The [[Characters/ChaosWars character sheet]] has been recently overhauled, but still needs to be heavily worked on. Any contributions will be appreciated.
!!Provides examples of:

* AllThereInTheManual: The bookshelf in the hub provides info on each character, their Realize weapons, personal bio, origin, and even artwork.
* ArbitraryHeadcountLimit: You can only have 5 units sortied on the field at any given time, out of your lot of 40+ units.
* {{BFS}}
* BlindIdiotTranslation: This and the English voice acting is [[BileFascination what got the game most of its attention]].
** The game ''Rebirth Moon'' was erroneously translated as "Reverse Moon". While リバース could be either "Rebirth" or "Reverse", this is a game that had a Latinised name visibly displayed on the its logo and [[http://www.ideaf.co.jp/rebirthmoon/top.html in the address of its official website]].
* ButtMonkey: Hayatemaru
* CasualDangerDialogue: [[http://www.youtube.com/watch?v=bangt7d9vGA This]] may be one of the best (albeit unintentional) examples of this trope ever.
* ChargedAttack: Realize specials, which require a certain amount of SP and 1 S gauge to use.
* CombinationAttack: Group Attacks, which need both of the characters to be in range and all have 1 S gauge.
* DeadpanSnarker: Hyōma
* DefeatMeansFriendship: Beating certain boss characters with a specific unit (sometimes the killing blow must have the unit in Realize mode) causes the boss character to join Hyōma's party after the fight is won.
* DualWielding and GunsAkimbo
* DullSurprise: Doesn't even begin to describe how bad the acting is. It sounds like 9th graders being forced to read aloud from a book that none of them are interested in. [[http://www.youtube.com/watch?v=bangt7d9vGA Here's an example]]. Thankfully, it's possible to switch to the Japanese voice track in the settings.
* EverythingsBetterWithMonkeys: Lubul
* FragileSpeedster: Mika is quite fast and can strengthen Beyond the Grave if she participates in a combo attack with him, but it doesn't take much to knock her out of the fight.
* GenderBlenderName: Nicole, as a result of using the original Japanese ''VideoGame/ShadowHearts'' name.
* GenkiGirl: Shizuku
* GoldfishPoopGang / QuirkyMinibossSquad: Gaizan and Emily, Shelley, among others.
* GlobalCurrency: Dia
* GuideDangIt: Standard fare for Idea Factory games and this one is no exception. Finding all [[OptionalPartyMember possible playable units]] is no easy task and to get some of them requires counterintuitive or obscure actions, and there's no real hints anywhere.
* HardDrinkingPartyGirl: Luwenelva
* HubLevel / PlayerHeadquarters: Hyōma and company find a summer house on a nearby island and lay claim to it because "no one's using it". Hyōma can speak to up to three characters that randomly spawn in the base, arrange his army, use the terminal to accept missions or shop/upgrade weapons and so on.
* ImprobableWeaponUser: Zard the "old-fashioned" detective uses a ''Franchise/KingdomHearts''-esque giant key during Realize, Gepetto uses his trademark puppet Cornelia when in Realize, Rocketbilly Redcadillac uses his electricity-shooting guitar when in Realize, etc
* IncurableCoughOfDeath: Sōji Okita has tuberculosis in his world, and will eventually die of it just like his [[UsefulNotes/TheShinsengumi real life counterpart]]. In Endia, however, he's perfectly healthy. (see below):
* IdiotHair: Several characters, but most noticeably Rin, who can be quite clueless.
* [[ContractualImmortality I Got Better]]: Ehhhh... [[{{Handwave}} Well whatever you want to call it]]. Basically, anyone who gets summoned to Endia gets cured of any ailment they suffered from in their world (such as Okita's IncurableCoughOfDeath). The most blatant example is Grave. In his home series, "Deadman" like Grave had to periodically undergo specially-prepared treatments that refreshed all the blood in their body in order to stay "alive" and mobile. In Endia, Grave no longer requires this, ''and'' still has all his powers (nor does he need to eat or sleep). NICE!
* LoadsAndLoadsOfCharacters: There's about 60 characters, both original and crossover, to find and recruit.
* JunglePrincess: Wruzel
* MacGuffin: The Keys
* TheManBehindTheMan: [[spoiler: The Egg of the World.]]
* MassiveMultiplayerCrossover
* MeaningfulName: [[spoiler: Rin '''Sunroad.''']]
* MightyGlacier: Beyond the Grave hits hard, but slow. He ''can'' grow out of this and catch up with other units, with the right accessories.
* MirrorBoss: [[spoiler: Late in the game, you'll encounter Mimics, which are copies of some of your units, like Grave or Carmine.]]
* NewGamePlus: Allows carryover of bookshelf entries, money, and any items/equipment you were not using/equipped with.
* NiceJobBreakingItHero
* OppositeSexClone: [[spoiler:Endia, the "boy of the sun", was a construct created by the Will of the Egg of the World, which also created Rin, the gate master.]]
* OverratedAndUnderleveled: Many of the late-game recruits, like Shelley, Poly-tan, and especially [[spoiler:Endia]] whom you literally get [[EleventhHourRanger right before the final battle]].
* PaperFanOfDoom: These are Shizuku's weapon of choice when in Realize mode. Outside of battle, she tends to playfully whack other characters with them.
* ThePowerOfFriendship: In a sense--some characters (Grave and Mika, Billy and Juji, Hyōma and his two friends, etc.) have a passive skill called "Friendship"/"Partner". It raises the attack power of the characters when they participate in combo attacks.
* RankInflation: Higher grades at the end of a match yield more money and items.
* RecursiveCanon: Poly-tan's Realize weapon is... ''Chaos Wars''.
* RecursiveReality: Sort of. Since ''Shinsengumi Gunrouden'' is taken straight from the events of [[UsefulNotes/TheShinsengumi the eponymous real life group]], OriginalGeneration character Hyōma Kusaka of LikeRealityUnlessNoted knows who Sōji Okita is.
* RedemptionDemotion: That boss character that had a ton of hit points and resilience? Joined your party? Well, the good thing is that you don't have to fight him or her anymore, but once on your side their incredible power is all but gone, as well as most of their hit points.
* RuleOfCool: Your party can consist of an OrdinaryHighSchoolStudent who can generate a FlamingSword, a [[VideoGame/ShadowHearts guy who can transform into an EldritchAbomination]], an [[VideoGame/{{Gungrave}} undead gunslinger who carries a coffin on his back and wields guns akimbo]], a demon girl who uses a big-ass scythe, and the ''[[UsefulNotes/TheShinsengumi Shinsengumi]]''. Tell me that's not ''awesome''.
* SinisterScythe: Hiro's Realize weapon is a large scythe, although she's not evil at all--she's practically one of the first few party members you get. Scythes/sickles are also a weapon class.
** While Hiro is not evil, she IS ruthless and without mercy (she outright tells Hyoma she will kill him if he becomes a burden or, worse, an obstacle), and in her own canon she has a SuperpoweredEvilSide that revels in wanton destruction and cold-blooded murder due to it representing her repressed demonic nature. The scythe is more fitting than it appears at first.
* SpellMyNameWithAnS: Many Non-OriginalGeneration characters, likely due to O3 Entertainment (the American localisation team) working from the original Japanese names rather than [[DubNameChange the pre-existing localised names]].
** Most noticeable with ''VideoGame/ShadowHearts'' characters: Uru might be better known to American gamers as Yuri. Likewise, Nicole is based off the original ニコル[[note]]''Nikoru''[[/note]], rather than the altered Nicolai.
* StatusBuff
* {{Stripperiffic}}: Ovia the witch, who seems very aware of it.
* ThrowTheBookAtThem: Books/tomes are a weapon class.
* TheQuietOne: Beyond the Grave and Zeonsilt.
* TrappedInAnotherWorld: Pretty much the whole premise.
* TheVeryDefinitelyFinalDungeon: [[spoiler: The Tower of Life]]
* UnexpectedCharacter: This game getting a US port. At least half of the non-OriginalGeneration characters have not made an appearance in any previous game for that region.
* VendorTrash: Conversion items only seem to exist for selling.
