A Mind Screwdriver is a side-story, sequel, or piece of bonus/AllThereInTheManual material that exists at least partially for the purpose of clearing up a MindScrew and/or GainaxEnding. When done well (and presented in such a way that viewers can easily find it), a Mind Screwdriver can make an already interesting plot that much more so, and even add a new layer of depth to the story. When done poorly, it can feel like a rather lame attempt to clear things up that the creators really should have just explained the first time around, or [[FanDislikedExplanation a total cop-out]] for those who ''did'' enjoy the nonsensical nature of the original scenario. Rarely, a Mind Screwdriver can actually become a Mind Screw in its own right, answering some questions while raising countless others of its own: when that happens, you might have something akin to VoodooShark.

Chances are very, very good [[NoExportForYou this never made it out of the country of origin]].

Not to be confused with [[INeedAFreakingDrink the freaking drink you need]] after experiencing a particularly baffling MindScrew.

[[folder:Anime & Manga]]
* ''Anime/BoogiepopPhantom'' makes a lot more sense if you've read the "Boogiepop and Others" and "Boogiepop At Dawn" light-novels beforehand (neither of which were localized when the anime was).
* ''[[Anime/FinalFantasyVIIAdventChildren Advent Children]]'' pretty much exists entirely to clear up the MindScrew at the end of ''VideoGame/FinalFantasyVII''. ([[JustHereForGodzilla And/or action scenes.]]) Or at least assure the world that they hadn't intended the ending to be an EveryoneDiesEnding. It does leave unanswered questions of its own.
** The director's cut version adds more scenes that explains background events that were covered in the original game, the novel, and the spin-off.
** Better candidates for the Mind Screwdrivers of ''[=FFVII=]'' and its Compilations are the [[NoExportForYou Japan-only]] Ultimania books which do explain a number of plot points and answer many long-asked questions.
* The DVD commentary for ''Anime/{{FLCL}}'' clears some things up.
* The 13 episode ''Anime/{{Kyousogiga}}'' anime series is this to its [[MindScrew infamous Episode 0]].
* ''The End of Evangelion'' was ''supposed'' to clear up the lingering questions left behind by the [[GainaxEnding notorious series ending]] to ''Anime/NeonGenesisEvangelion''. However the movie managed to clarify some things about the plot while still leaving massive questions unanswered, introducing whole new ones, and being a complete and unmitigated MindScrew in and of itself.
** There is an ''Evangelion'' video game that was [[{{NoExportForYou}} only released in Japan]] that contains unlockable [[AllThereInTheManual notes about the backstory of the anime]]. They explain things like where Adam and Lilith came from ([[spoiler:they were beings created by SufficientlyAdvancedAliens to seed planets with life, and were never intended to end up on the same planet]]), what the Angels were trying to accomplish ([[spoiler:by reaching Adam, they would've started their own version of the Third Impact, which would've wiped out all Lilith-based life and replaced them with Angels]]), why Shinji and Asuka returned together ([[spoiler:Shinji essentially could not conceive the idea of living in a world with no Asuka, and she needed him as much as he needed her]]), and why Shinji tried to choke her ([[spoiler:he was so distraught after Instrumentality that he could not be sure that she was real, so he tried to force a reaction out of her]]).
* In the ending of ''VideoGame/TheLegendOfZeldaTwilightPrincess'', after being defeated, [[BigBad Ganondorf]] stands back up, and, while [[ImpaledWithExtremePrejudice grievously wounded]], expresses a desire to continue the fight. Suddenly, the [[MarkOfTheSupernatural mark of the Triforce]] on his hand goes out. Cut to [[DiscOneFinalBoss Zant]], who jerks his head to the side with a NeckSnap sound. Cut back to Ganondorf, who abruptly dies. [[Manga/TheLegendOfZeldaTwilightPrincess2016 The game's official manga adaptation]] explains Ganon's thoughts in more detail: the Triforce of Power left him because he willingly deactivated it, choosing to [[BetterToDieThanBeKilled die on his own terms]] rather than accept the harmony of the three Triforces existing in balance. His last words weren't because he was still fighting right now, but because he knows he'll come back AsLongAsThereIsEvil. Zant... is addressed by not adapting his last scene.
[[/folder]]

[[folder:Comic Books]]
* ''ComicBook/TheIncredibleHulk'': Issue #34 of ''ComicBook/ImmortalHulk'' serves as this for not just the run itself but the series in general, running through its entire history [[PerspectiveFlip from the perspective]] of the BigBad and, in doing so, tying together countless disparate plot points and providing vital context to a lot of what's been happening. By the end, there are still some unanswered questions and things left ambiguous, but you have a much better handle on what the Hulk is actually dealing with.
* The introduction of the 1980s comic book sequel to ''Series/ThePrisoner1967'' rationalized away the strange last episode. [[spoiler:They fed Number 6 [[MushroomSamba LSD]], which also makes it an HappyEndingOverride]].
* ''ComicBook/TeenTitans'':
** ''ComicBook/TeamTitans'' makes no sense towards the end, as it is vaguely revealed that the team and its creation were all lies created by renegade Titan Hawk/Monarch. The "true purpose" of the team was supposed to be revealed in ''ComicBook/ZeroHourCrisisInTime'', but little was revealed and outside of Terra II and Mirage (and the Team Titans who were existing Titan characters hanging around), the entire team was wiped out of existence with zero build-up or follow-up when their timeline got nuked.
** Terra II and her origin is another one, along with Amanda Connor's ''ComicBook/{{Terra}}'' mini-series that focused on the third Terra, as well as Brad Meltzer's aborted storyline involving Deathstroke and Terra's half-brother Geo-Force in ''ComicBook/JusticeLeagueOfAmerica''. Interviews with the writers had to sort things out as far as explaining away the entire thing, due to the comics offering no answers: Terra II was a soldier from a non-humanoid subterranean kingdom who took Terra's form under the (unknowing) notion that the surface world would accept her as an emissary if she looked like a fallen "hero" (the kingdom did not know Terra was a traitor). Time Trapper got a hold of her and mindwiped her, then planted her in a future timeline that Monarch was using to raise the Team Titans as his private evil army. Deathstroke later stole the original Terra's body so he could duplicate the process of how Terra got her powers. Deathstroke used his knowledge to force his half-sister's powers onto Geo-Force, knowing he would not be able to control them. To further torment Brion, Slade also implied that the powers would eventually drive him insane "like his sister", as Slade then claimed Terra only went evil because of her powers affecting her mind and the mind control serum he used on Batgirl Cassandra Cain not working well together and causing irreversible madness. Slade wanted Geo-Force to betray the Justice League for him but Geo-Force stopped Slade and (off-panel) it was revealed that everything Slade said to Brion about Terra was lies designed to terrorize Brion and further manipulate him into serving Slade lest he go insane from his newfound powers. And Terra III? After Terra II died at the hand of Black Adam in ''ComicBook/FiftyTwo'', the princess of the underground kingdom underwent a similar process to make her human though with a completely different appearance.

[[folder:Fan Works]]
* ''Fanfic/OneStepBackwardsAndThreeForwards'': The "Dear [You]" arc hits the audience with so many twists and turns that when it concluded in Chapter 27, the author offered to answer questions in the comments section for that chapter and help explain just what had unfolded/been revealed.
* ''FanFic/ThousandShinji'' delivers a LampshadeHanging[=/=]TakeThat to the MindScrew of the original ''Anime/NeonGenesisEvangelion'': "For those of you prepared to rant at me, there is one more chapter to this story, so unlike Gainax, you will actually get an explaination as part of the denouement." It then proceeds to do just that, having [[spoiler:the canon!40k gods]] explain what looked like a GainaxEnding.
[[/folder]]

[[folder:Films]]
* Much of the film ''Film/TwoThousandTenTheYearWeMakeContact'' is devoted to explaining the ambiguities of its predecessor, ''Film/TwoThousandOneASpaceOdyssey''. Would also qualify for an in-universe example, as the characters themselves are seeking the answers. However, it's also worth noting that there isn't actually much explained (such as just what happened in the trippy ending sequence) and if anything it raises even more questions. [[spoiler:(The bit about Hal seemingly going homicidally insane is the only thing that is ever made clear.)]] You could also [[AllThereInTheManual read the novels]], but not even in the original novel was much explained beyond [[spoiler: what happened to Hal and a few suggestions as to what the Monolith ''might'' be]].
* ''Film/DonnieDarko'' has the eponymous character who receives a book on time travel from his science teacher, time traveling also being the central plot driving device of the movie. A director's cut released a few years after the original DVD release briefly cuts to pages from said book, where the mechanics of time travel in this movie are explained - which is vital to figuring out what the hell is going on. The book was later actually published and released. It explains most of the background and events present in the movie. Yet while it explains some of the time travel mechanics, the closest thing we have to an explanation of where Frank came from or who is manipulating Donnie is a couple lines [[WordOfGod in the commentary]] saying that [[ShrugOfGod maybe]] it's [[AWizardDidIt God.]] Or [[SufficientlyAdvancedAliens aliens]]. [[ShrugOfGod Whatever]].
* ''Film/{{Memento}}'''s plot makes sense on its own (as long as you can keep up with it), but the [[http://www.otnemem.com website]] gives an awful lot of backstory (including spoilers) that lend a much fuller understanding.
* The MindScrew ending of the 2001 remake of ''[[Film/PlanetOfTheApes2001 Planet of the Apes]]'' only makes sense if you visit the (now inactive) website for the movie and learn that [[spoiler:Thade learns how to use human technology while trapped in the Oberon, and when he eventually escapes he fishes Leo's original pod out of the swamp, restores it to working order and flies into the electromagnetic storm after him, arriving earlier than he did and inciting a second ape rebellion.]]
* ''Film/SouthlandTales'' has a tie-in graphic novel which explains a lot of background for the film's convoluted plot. However, for many viewers, it suffers from being so ambitious that they're not willing to decipher it. While the books (the movie's only part 4-6; 1-3 are a graphic novel) do fill in lots of backstory, online director interviews and other breakdowns are quite helpful in clarifying the deep, yet admittedly confusing, film.
* Several small scenes during the credits of ''Film/WildThings'' piece together the otherwise incomprehensible series of twists and turns the story takes.
[[/folder]]

[[folder:Literature]]
* ''The Book of Lost Memories'' was written to explain the mountains of symbolism (but not the plot) in the first three ''Franchise/SilentHill'' games. Whether this lessens the ambiguity or makes an already {{Mind Screw}}y series even more impenetrable is still up for debate.
* ''The Essence of VideoGame/SaGaFrontier'' and ''Complete of [=SaGa=] Frontier'' both go a long way to explain various details that were glossed over in the game or [[WhatCouldHaveBeen wound up on the cutting room floor]]. [[NoExportForYou Neither book made it out of Japan]].
* ''Literature/FungusTheBogeyman'': The book points out that if the Man in the Moon was a Bogeyman, the rhyme would make more sense: he went by the south to avoid the heat and he burnt his mouth on cold plum porridge because Bogeymen are very sensitive to burning.
* ''Literature/PicnicAtHangingRock'' had an 18th chapter which explained just what happened to the missing girls. It was excised by the publisher. It was later released as ''The Secret of Hanging Rock'' decades later[[note]]What happened, basically, is the missing girls went through a "hole in space"[[/note]].
* The ''VideoGame/{{Xenogears}} Perfect Works'' books provides backstory and detailed exposition necessary to understand a game so choked with symbolism and {{Mind Screw}}s.
* ''Literature/TheSoundAndTheFury'' is a fascinating example in that each section of the book serves as a Mind Screwdriver for the previous section, with the narrative becoming more coherent with each change in narrator/perspective. It starts out extremely hard to decipher due to being written from the POV of a severely mentally disabled man [[StylisticSuck who moves in and out of flashbacks without warning nor exposition]]. Then it becomes a little easier to understand but still challenging due to the narrator being a young man in the midst of a nervous breakdown whose style of thought becomes [[PaintingTheMedium increasingly strange]] as [[SanitySlippage his mind crumbles]]. The third section sees the writing suddenly become coherent by switching to the view of a functional grown man, with the only challenging elements being [[VillainProtagonist his extremely unlikable nature]], self-absorbed ignorance of others, and tendency to derail things with nihilistic cynicism and denigration of the people around him. Next we get to the point of view of the book's [[OnlySaneMan only sane woman]] and things get downright sensible, as she reflects on the situations the cast are involved in, writes and speaks intelligently, and generally plays the role of a neutral observer who gives the reader an objective source of information. Finally it all caps off with an appendix that ties off all the loose ends, answers the remaining questions, and provides much-needed context.
* The whole final chapter of ''Literature/AndThenThereWereNone'' is dedicated to explaining what the hell all just happened by recapping the events of the book from the killer's perspective.
[[/folder]]

[[folder:Live-Action TV]]
* The GrandFinale of ''Series/AshesToAshes2008'' impressively managed to be one of these for not just ''Ashes'' but its parent series ''Series/{{Life On Mars|2006}}''.
* The final season of ''Series/{{Lost}}'' was supposed to be this. It both succeeded and/or failed spectacularly. Fans were divided. It didn't help that some subplots from the previous season had been cut, taking away the chance for the past events to be as fleshed out as they were originally intended. The season six [=DVDs=] contain an epilogue which explains a whole lot of the remaining mysteries.
** Once the exact nature of the sideways universe was revealed, it made relative sense of what would have been egregious plot holes had the universe been what it initially appeared to be.
* Bruce Kalish had to explain a good deal of ''Series/PowerRangersSPD'''s plotholes in interviews after the fact. Also, the official website explained that A-Squad had been brainwashed (as opposed to the improbable apparent scenario in-show: the whole team deciding to [[FaceHeelTurn go bad]]).
* The online material for ''Series/{{Smallville}}'' often clears up some of the backgrounds and relationships of certain groups and characters, like the history of Smallville and how it connects to Krypton, or the Veritas society.
* Although it all makes sense, some ''Series/StargateUniverse'' fans were confused by the ending of the episode "Time" and/or the fact that everything is back to normal by the start of the next episode, so a subsequent Kino Webisode referenced the issue. Eli explained that Scott's Kino went back in time like the first one, but as it contained all the information they needed in order to cure the parasite in the water without being killed by the aliens, everything turned out fine.
[[/folder]]

[[folder:Music]]
* The ''Music/EvilliousChronicles'' is much more easy to understand with the novels, which carry the bulk of the story that is often confusingly condensed into the songs (which are released first). Still, while fans are waiting on that for their clarification, Music/{{mothy}} often releases his albums with exposition booklets that serve as this.
* The concept of ''Heartland'' by Music/OwenPallett is not explicitly explained in the lyrics and there is no booklet, so the only reason anyone knows what it's about is that [[WordOfGod Pallet has explained it]] in interviews. It's about a "young, ultra violent" 14th Century farmer named Lewis who lives in a land called Spectrum. He knows that he and his world are creations of Pallett, but it's unclear whether he's always known or if he figured it out at some point. It's impossible to fully understand any of the songs unless you're Pallett (and maybe not even then), but certain things can be gleaned. For example, in the penultimate song "Tryst with Mephistopheles", [[spoiler:Lewis kills Pallett]].
* The story that Music/PeterGabriel wrote for the liner notes of the Music/{{Genesis|Band}} ConceptAlbum ''Music/TheLambLiesDownOnBroadway''. Though it actually doesn't explain things very much. For that, see [[http://www.bloovis.com/music/lamb.html this site]]. And prepare to walk away ''still'' [[GainaxEnding not sure]]...
[[/folder]]

[[folder:Video Games]]
* ''VideoGame/AssassinsCreedRevelations'' is the screwdriver for the ''Franchise/AssassinsCreed'' series up to that point, explaining what happened at the end of ''[[VideoGame/AssassinsCreedBrotherhood Brotherhood]]'' as well as revealing more about [[spoiler: the first civilization]]. Of course, there are still mysteries to be solved by subsequent games.
* ''VideoGame/BalanWonderworld'' has little in the way of overarching narrative, no dialogue in cutscenes except at the very beginning and very end, and the characters are all SpeakingSimlish. It has a tie-in novel that explains ''everything''.
* The final ending of ''VideoGame/TheBindingOfIsaac'', Ending 20 of Afterbirth+, has [[spoiler:Isaac in his toy chest, his life flashing before him. You hear his mom and dad arguing, and see a shot of Isaac watching his mother cry in front of her TV. As Isaac begins to turn blue from lack of oxygen, we see Isaac holding a family photo with his dad's face burned away, with other photos that have received the same treatment and (perhaps most heart-wrenching of all) a series of Isaac's drawings, showing his descent into self-loathing and suicidal insanity (BAD BAD BAD I'M THE DEVIL). Finally, we see a shot of Isaac's skeleton within the chest as his mother opens it, and the missing poster from Ending 15 flies away, symbolizing Isaac's demise. The final shot of the ending is Isaac walking through the afterlife from Ending 17, while a somber remix of the title theme plays]]. To clarify the entire thing, [[spoiler:the entire game has been Isaac's DyingDream as he suffocated to death in the toy chest that he locked himself into]]. [[DownerEnding It's a depressing note to end things on]], but given the nature of the game in general, it's all too appropriate. The next DLC, Repentance, changes it to more of a BittersweetEnding though.
* The second ''VideoGame/CalmereNightmare'' map explains that at the end of the first map, [[spoiler:[[GoMadFromTheRevelation the protagonist went insane]], meaning that we were watching the ending ThroughTheEyesOfMadness]].
* ''Trilby's Notes'', of the ''VideoGame/ChzoMythos'', ended with the title character being saved by an unknown man in red. The identity of this man was not revealed until the ending of the next game, and it was itself a mind screw. It also explains how the man was able to revive Trilby.
** The Special Edition versions of the games (especially ''6 Days'') provide a few other Screwdrivers as well, most notably [[spoiler:why Chzo was interested in the FailureIsTheOnlyOption {{plan}} at all.]] The commentary and extended ending of 6 Days also explicitly explain [[spoiler:the Tall Man's behavior in Trilby's Notes and 6 Days]].
* At the end of ''VideoGame/TheCurseOfMonkeyIsland'', [=LeChuck=] can explain the ending of ''[[VideoGame/MonkeyIsland2LeChucksRevenge Monkey Island 2]]'', if prompted. It takes some time.
* ''VideoGame/ReturnToMonkeyIsland'' plays it straight in the opening but plays with later in the tale.
** In the opening [[spoiler:the end of ''Monkey Island 2'' turns out to be be the result of Boybrush and his friend Chucky doing their own spin on whatever actually happened in that tale, with his father Guybrush telling him you can't just change endings like that.]]
** Later on [[spoiler: you get to choose how to interpret Guybrush's intentionally silly ending. Was that adventure really all a theme park ride? A metaphor for how disappointing the real secret was? Or was he making the mother of all dad jokes by copying his son's storytelling style to show him why stories need a satisfying ending?]]
* ''VideoGame/DigitalDevilSaga 2'' explains what exactly the MindScrew that was the GainaxEnding of ''VideoGame/DigitalDevilSaga'' meant (making ''perfect sense'', by the way).
* A couple years after the first game in the ''[[VideoGame/GadgetPastAsFuture Gadget]]'' series, ''Invention, Travel, and Adventure'', was released, a tie-in art book called ''Inside Out with Gadget'' was published. Whereas the game deliberately didn't explain almost anything in order to create an uncomfortable atmosphere, the book gives more context to the setting, some character motivations, and timeline; for example, explaining how the titular gadgets were powered, Orlovsky's plans for the Empire, and how the Sensorama was created and used as a brainwashing machine. Some of these additions by the book would go on to be referenced in ''Past as Future'', which was a remake of the first game, such as how the [[CreepyChild mysterious boy]] was once put into the hospital, and that the substance used to create the gadgets was mined from a meteor. However, the art book seemingly cannot be used to completely explain either game's story, as there are plot points that are never referenced in either game, like Horselover Frost possibly being an InventedIndividual and Orlovsky being murdered by Louis Hausmann, meaning that ''Inside Out'' was likely meant to tell its own self-contained story much like the other tie-in novel, ''The Third Force'', and it can only be used to explain the games to a certain point.
* ''Franchise/{{Halo}}'': Halsey's Journal in the ''VideoGame/HaloReach'' Limited and Legendary Editions, as well as the various ONI Reports released before the 10th Anniversary UpdatedRerelease of the [[VideoGame/HaloCombatEvolved original game]], serve the purpose of placing the events of ''Reach'' within the previously established timeline of the Fall of Reach (specifically, the one given in the original ''Literature/HaloTheFallOfReach''). The success of this is questionable due to the sheer number of retcons and the severity of those retcons, including what was previously a battle that lasted for less than a few days now taking the better part of a few months.
* ''VideoGame/HotlineMiami'', like most games by Creator/{{cactus}}, is ''weird'', feeling like an insane, barely-coherent technicolor orgy of unexplained violence and destruction. But if you [[spoiler:get the GoldenEnding by collecting all the hidden letters, solving the puzzle they form, and using the result as a password on the {{Big Bad Duumvirate}}'s computer]], the plot comes back down to reality. Relatively speaking.
** While it contains its own share of unexplained MindScrew, ''VideoGame/HotlineMiami2WrongNumber'' serves as this to the first game's plot, which can be best described as a JigsawPuzzlePlot where [[MindScrew a mental patient stole half the pieces.]] Notable explanations include:
*** The mysterious Russo-American coalition. [[spoiler: It's the result of a war between Russia and the US that Jacket fought in, which degenerated into grueling island warfare until San Francisco was nuked by Russia, forcing America to accept a cease-fire in a dark mirror to the ending of UsefulNotes/WorldWarII.]]
*** The Bearded guy who works everywhere and gives you free stuff for no reason other than to be nice. [[spoiler: He's a war buddy of Jacket's who saved his life in a combat zone, and brushed off attempts to repay him as it being [[ThinkNothingOfIt "on the house."]] He died in the tragedy at San Francisco before the first game, and his appearances are all part of Jacket's coma dream.]]
*** The mysterious photo that Jacket releases to the wind in the game's ending. [[spoiler:It's a picture of him and Beard in Hawaii during the war, before his life went wrong. Beard gave it to him as a keepsake after saving his life, on the condition that he send him a copy once they get home. Unfortunately, he died before Jacket could do it.]]
* The game version of ''VideoGame/IHaveNoMouthAndIMustScream'' was made to further flesh out the characters in the original story as well as answer the question as to why AM was doing what it was.
* Hand in ''VideoGame/Killer7'' was ''supposed'' to be this, but because it was made before the game was finished, some of the material in it wasn't used in the game. So, while reading Hand in [=Killer7=] makes sense of some of the plot, it makes the rest of it [[MindScrew even more mind screwy]].
** Devil's Due Publishing started releasing a comic adaptation as well that would attempt to make the plot more coherent, but only four of the issues were released before the whole thing was canceled, leaving the explanation half-finished.
* The Ansem Reports in the first ''Franchise/KingdomHearts'' game.
** ''VideoGame/KingdomHeartsBirthBySleep'' is also a Mind Screwdriver, filling most of the holes left by its predecessors... of course, only to set up plot elements that evolve into an even ''bigger'' MindScrew in the ''next'' entry of the series, ''VideoGame/KingdomHearts3DDreamDropDistance''.
* One of the biggest, EpilepticTrees spawning questions in ''Franchise/TheLegendOfZelda'' was the question of the games' timeline--how did they all fit into each other? Which games preceded others, and which were immediate sequels? Fans spent ''decades'' trying to figure it all out, until, in the New Tens, Nintendo published ''Hyrule Historia,'' a book all about the games and their universe. This book revealed a key piece of information--canonically, the games follow a set path until ''VideoGame/TheLegendOfZeldaOcarinaOfTime.'' At the end of that game, the timeline splits into ''three'' distinct paths: the "Adult" Timeline, wherein Link defeats Ganondorf as an adult and returns to the past (which leads to the events of ''Wind Waker'' and its direct sequels); the "Child" Timeline, which has Link tell Zelda about Ganondorf's plots before he can even enact them (which created the events of ''Majora's Mask'' and ''Twilight Princess''); and, most depressing of all, the "Fallen" Timeline, where Link ''dies'' fighting Ganondorf and forces the Sages to bind the wizard at full power (which corrupts the Sacred Realm and produces the world of ''A Link to the Past'' and even the ''original'' Zelda). ''Hyrule Historia'' is [[WordOfGod officially canon]], and while websites (including this one!) have spread the information beyond it, the book remains the Screwdriver that solves the puzzle that plagued players for so long. This however didn't stop the MindScrew from returning in the very next mainline game to release after ''Hyrule Historia'': ''VideoGame/TheLegendOfZeldaBreathOfTheWild'' which had oddities and mutually exclusive events (the Rito and the Zora both exist, despite the Rito only existing in ''Wind Waker'' because the Zora were forced to evolve) that once more cast confusion on how time in Hyrule was flowing. WordOfGod refused to specify an exact timeline, raising more questions. And just to make things even more confusing, the direct sequel ''VideoGame/TheLegendOfZeldaTearsOfTheKingdom'' [[spoiler:establishes a new backstory for the Kingdom of Hyrule that includes the Zonai and a different incarnation of Ganondorf who has no relation to the first time-split]].
* ‘’VideoGame/LiveALive’’ received its screw driver in an event in ‘’VideoGame/OctopathTravelerChampionsOfTheContinent’’ which answers many unexplained questions in the Middle Ages chapter. This event is canon in the sense that Umineko’s Confession of the Golden Witch is canon.
** Althea [[spoiler: would have eventually had mutual feelings towards Oersted if not for Streighbough’s actions]].
** Live A Live is implied to take place in the same multiverse as Octopath Traveler. The main connecting point being that [[spoiler: Odio is connected to Galdera via an unknown way]].
** [[spoiler: Odio and Oersted are not the same person. Odio was the original Lord of Dark]].
** The statues were made [[spoiler: by the original Lord Of Dark who could see into both the past and the future as part of later plots]].
** Incarnations are basically [[spoiler: host full of hate + power source. However, the incarnations plot required the previous Lord of Dark to have a main host that can best be described as “Odio Prime” which os where Oersted comes into the picture]].
** Streighbough is [[spoiler: NOT an incarnation so much as someone channeling Odio’s power to his own ends, like Mattias. The channeling most likely starting at the statue]].
* ''VideoGame/MassEffect3'':
** The [[AuthorsSavingThrow Extended Cut]] of the game's infamous endings clarifies (and possibly outright {{retcon}}s) the original, [[GainaxEnding confusing]] {{Esoteric Happy Ending}}s that had the fandom up in arms with rage.
** The ''Leviathan DLC'' gives more clarity on [[spoiler:the Catalyst's and Reapers origins]].
* ''VideoGame/MetalGear'':
** ''VideoGame/MetalGearSolid4GunsOfThePatriots'' managed to clear up the plot of ''Sons of Liberty'', at the price of creating a truly spectacular ContinuityLockout and DoingInTheWizard. And if that weren't enough, the free "MGS Database" app released to promote ''Guns of the Patriots'' further clarifies things.
** ''VideoGame/MetalGearSolid3SnakeEater'' was essentially the first half of the series' screwdriving process. Specific example: although it's very easy to miss, the whole subplot with The Sorrow serves to very neatly retroactively explain why Ocelot could be possessed by Liquid in the second game: [[spoiler:[[InTheBlood because Ocelot's father was a medium]]]].
** Speaking of ''VideoGame/MetalGearSolid2SonsOfLiberty'', the game was going to contain a Mind Screwdriver of its own in the form of Psycho Mantis' mask as an unlockable. It was going to let you hear the thoughts of other characters during cutscenes/codec calls, and those thoughts were supposedly going to give you a major clue to what was really going on in the game's plot. But alas, [[ChristmasRushed the game was rushed for the holidays]], so it didn't get implemented.
* The ''VideoGame/{{Myst}}'' series has a lot of mysteries (of course), though the side-novels (canon, and written by the creators) explain massive chunks of backstory. Why was Gehn trapped in Riven? How did Myst Island come to be? What is Atrus's backstory? How was the Dn'i destroyed? The books explain all of this.
* ''Franchise/ResidentEvil'':
** ''VideoGame/ResidentEvilTheUmbrellaChronicles'' is a retelling of several games in the ''Franchise/ResidentEvil'' series which attempts to fill in the plot holes the previous games left behind. (''VideoGame/ResidentEvilCodeVeronica'' featured a video, on a bonus disc, which tried to do the same; "The Wesker Report" was subsequently made obsolete when the next games retconned the story in a different way.)
** And ''VideoGame/ResidentEvil5'' had a nice Author's Saving Throw, though it might be a VoodooShark, explaining what was up with how Wesker got better, one of the main parts that was kept. [[spoiler: Original Version. Wesker got a secret formula that turns people into sentient uber-not-zombies. Second explanation, turns out Wesker was part of an old Umbrella project, it was leaked to him, and the formula only works for him thanks to injections he takes to keep from going OneWingedAngel]].
* The Once Upon A Time chapter that shows up at the end of ''VideoGame/RuleOfRose'' is one of these, if you get the good ending.
* ''VideoGame/{{Spiritfarer}}'': The purpose of Lily is to explain some of the metaphors in the game. [[spoiler:Mainly, the fact that Stella is having a DyingDream.]]
* ''VideoGame/TheWorldEndsWithYou'': The Secret Reports. Of course, getting them all unlocks TheStinger, which is more confusing than anything in the actual plot.
* ''VideoGame/XenobladeChronicles1'' had a borderline GainaxEnding, with Shulk defeating [[GodIsEvil the evil god Zanza]] only to be told by Alvis that Zanza was once a human scientist who destroyed the previous world, turned himself into a god, and created a new one, in an experiment GoneHorriblyRight. And Alvis is the AI of the computer that ran the experiment. ''VideoGame/XenobladeChronicles2'' is a StealthSequel that, in its last few chapters, explains the context behind the experiment, who Professor Klaus was, what happened to the old world, that Zanza was Klaus' evil LiteralSplitPersonality, and that Alvis was one of the three Aegis. (Essentially making him a "long lost brother" of Mythra and Malos)

* In ''VisualNovel/AreaX'', Ferim's route is the last one you can do for this reason. Though Rexus and Livan's routes explain enough of the overall plot to give a general gist of what's going, both are heavily biased towards Rexus/Livan, respectively, and have to withhold spoilers for the other route, and so explain significant events only from the respective LoveInterest's POV. Ferim's route, on the other hand, shows the entire story, pieced together, and explains exactly why [[spoiler:the timelines are falling apart]].
* The "True Ending" of ''VisualNovel/{{Ever17}}'' clears up just about every mystery in the game. And some things that weren't, but were probably misinterpreted.
* ''[[VisualNovel/HigurashiWhenTheyCry Higurashi No Naku Koro Ni Kai]]'': Abandoned the "nice kids in rural Japanese town go nuts and start killing each other" premise in order to clear up the MindScrew of the first season in its entirety.
** ''[[VisualNovel/UminekoWhenTheyCry Umineko No Naku Koro Ni Chiru]]'' also does this, but to a lesser degree since WordOfGod stated that this half of the series was not meant to be the "Answer Arcs". While the end of the series still leaves some things unclear, [[spoiler:there's a good amount of evidence to establish that the witches and other magical beings aren't actually real in the first place]]. The manga also adds additional clues and red truths.
* ''VisualNovel/ZeroEscape'':
** The "True Ending" of ''VisualNovel/NineHoursNinePersonsNineDoors'' clears up a lot of mysteries (though it has its own [[TheStinger stinger]]), but on top of that, [[http://www.aksysgames.com/999/answers there's an interview with the director of the game]] [[AllThereInTheManual that offers additional information and clarifies some of the stranger points.]]
** The sequel, ''VisualNovel/VirtuesLastReward'', clears up [[spoiler:the stinger of the first game, explaining that the Alice seen at the side of the road (who everyone assumed was the All-Ice Egyptian priestess come back to life) was actually an undercover agent with a childhood and history and parents from the current time period.]]

* ''Webcomic/{{Homestuck}}''[='s=] three {{Recap Episode}}s (and similarly, the two ''Webcomic/ProblemSleuth'' recaps) are an invaluable aid to those who find themselves lost in the KudzuPlot. Creator/AndrewHussie's Formspring and the MSPA forums are also pretty handy references for clearing up ambiguous plot points.
* Chapter 24 of ''Webcomic/{{Namesake}}'' finally explains what's going on and why, both on cosmic scale and on Earth. Chapter 20's [[http://namesakecomic.com/comic/namesake-relationship-chart relationship chart]] is also quite handy.

[[folder:Web Originals]]
* ''WebAnimation/DuckTalez'': During episodes 4 through 6, Scrooge and Vegeta make sporadic and random appearances unrelated to the plots of said episodes. In episode 7, the focus is on them and we see exactly how those cameos fit into their plot.
* ''Website/ChannelAwesome'' takes place in its own fictional universe, with the reviewers playing avatars of themselves, ''WebVideo/TheAngryVideoGameNerd'' and ''WebVideo/TheSpoonyExperiment''. At the end of the fourth year anniversary, reveals a void called the PlotHole which in it removed all logical continuity. So literally any unrealistic thing, or paradox can happen and it would make perfect sense in their universe. (Despite all that happened long before the plot hole appeared, so literally asking questions about the logic in that universe is pointless now. Because there is none.)
** The fact that paradoxical things happen before the creation of the Plot Hole is also explained - since the Plot Hole is a tear in space ''and'' time, it can cause things to happen before its creation. The specific example given is how the second year anniversary event shows Dr. Insano as an evil split personality of Spoony's, when the rest of the continuity shows him as a separate person entirely.
** Before the Plot Hole was created, Linkara made one for a point in the third anniversary event. A major reveal in that event was that magic is incredibly draining and potentially lethal, unless the Gauntlet was used to cast it. In the commentary, Linkara realizes that this creates massive continuity issues with his own show (where he routinely uses a gun that's described as magic), so he says that he's always been safe because [[{{handwave}} his hat protects him]].
* ''WebAnimation/RedVsBlue'': ''Recreation'' and ''Revelation'' serve to explain a large amount of the wackier elements of previous seasons, most noticeably the "time travel" incident in Season 3 and any point in the series where a character died and got back up again.

* ''WesternAnimation/AdventureTime'':
** The show had a season one episode, "Tree Trunks", where the titular elephant bit into the crystal apple she was looking for so she could bake an apple pie out of it. She exploded, and then was seen giggling and laughing through the apple. [[GainaxEnding End Episode.]] Season two had a followup, "Crystals Have Power", where it was revealed that she'd been transported to the crystal dimension, where she went insane and became queen. She tried to turn Finn into her Crystal King, but Jake [[BeatTheCurseOutOfHim punched the crystal chunk out of her]] and she returned home to bake them another apple pie.
** The season one episode, "Evicted", ended with a GainaxEnding where Finn and Jake arrive to find their house is worm infested. A giant worm then hypnotizes them. The fourth season episode "King Worm" is about Finn trying to escape a dream that the same giant worm has trapped him in. The episode's ending then subverts this trope because it [[MindScrew hints that everything between "Evicted" and "King Worm" was]] AllJustADream ([[{{Jossed}} although this turns out not to be the case]]).
** The GainaxEnding of the season 4 finale "The Lich" is explained by the season 5 premiere episodes "Finn the Human" and "Jake the Dog"
** In the season three episode "The Creeps", Finn encounters a monstrous ghost woman in a haunted castle. At the end of the episode it was revealed that everything that happened was orchestrated by Jake... ''except'' for the ghost woman, which Jake thinks Finn must have imagined. The season five episode "The Vault" reveals that [[spoiler: Jake was almost right. Finn was having [[PastLifeMemories a distorted vision of his past life self, who had a connection to the castle.]]]]
