%% Due to the nature of this trope, finding a proper image will be very tricky.
%% Thus, do not start a thread without a solid suggestion.

Let us say you have several different characters and each one has [[PlotThreads their own separate journey]] for at least a portion of the story. These characters may or may not [[YouAllShareMyStory meet up with one another later on]], but for now they are all on their own and their journeys, while they may be related, are independent of one another at least for the time being. There are two ways of handling this: One way would be to tell every single event in chronological order, frequently cutting from one character to the next, and then to the next as each event plays out. This first method would be known as TwoLinesNoWaiting. For obvious reasons, stories told in RealTime would have to do it this way.

For stories that are not told in RealTime, however, there is another option. That option is known as SimultaneousArcs.

Let's say you have two different characters: Alice and Bob, and these characters are separated from one another and are doing their own thing for a while, but each one is doing it at exactly the same time as the other one. It would work something like this:

* Chapter 1 takes place between 1:00pm and 2:00pm and includes everything that happens to Alice during that time period without regard to what Bob is going through.
* Chapter 2 also takes place between 1:00pm and 2:00pm, except it is told from Bob's point of view and has absolutely nothing to do with Alice.

This process would be repeated until Alice and Bob meet up.

This differs from RotatingArcs because RotatingArcs is a method of dealing with LoadsAndLoadsOfCharacters and the arcs occuring in RotatingArcs don't have to occur at the same time.

This is similar to AnachronicOrder, except the events in each arc of SimultaneousArcs are probably told in the order that they occur from the point of view of the character and it is the arcs themselves that are not in chronological order.

This can sometimes result in a MindScrew, but it usually won't.

Compare HyperlinkStory. Can be related to RashomonStyle. POVSequel is when they decide to do this ''after'' making the original arc. TV episode variant is SynchronousEpisodes


[[folder:Anime and Manga]]
* The Hueco Mundo and Fake Karakura arcs for ''Manga/{{Bleach}}''. One is a RescueArc, the other is a BigBadassBattleSequence.
* ''Anime/BoogiepopPhantom'' is a possible example. In general, the whole anime is a complete MindScrew and it's extremely difficult to determine when exactly certain events took place or even to get a decent grasp on what is actually going on. There are several events that are shown multiple times, however, and each time it is shown, it is from a different perspective.
* The first two episodes of ''Anime/SpeedGrapher'' occur at roughly the same time. Episode One is told from the point of view of Saiga, while the second being from the point of view of Kagura, and both have roughly the same climax. The rest of the series is mostly told in Chronological order, with the exception of a few flashback episodes here and there.
* The fourth and fifth episodes of ''Manga/KOn's'' second season respectively focus on the third year students going on a class trip and the rest of the group staying at home during a rainy day, with events crossing over slightly when Yui sends Ui pictures during the trip with her cellphone.
* On at least two occasions, ''Manga/OnePiece'' has switched between this and TwoLinesNoWaiting, depending on the exact point in the story. When the Straw Hat Pirates get separated, we see Luffy's story reach its conclusion, then the other eight Straw Hat crewmembers, each with his or her own small arc, rapidly switching between each other. It happens again in the Dressrosa story, only the reader (or viewer) gets introduced to each of the five separate stories taking place, where it then proceeds to tell each simultaneous story until the necessary plot points come up before backing up and moving to another one where that information is necessary.
* In ''Anime/SaintSeiyaSoulOfGold'' there will apparently be several pairs of Gold Saints : Aiolia and Mu, Dohko and Aldebaran are already established.

[[folder:Comic Books]]
* ''ComicBook/SinCity'''s characters often run into each other in the middle of their respective stories at Kadie's Bar.
* ''ComicBook/{{Invincible}}'' has the Sequid arc (starring Invincible, the Immortal, Atom Eve, Robot, and Bulletproof) simultaneously occurring with the Lizard League arc (starring Rex Splode, Dupli Kate, and Shrinking Ray).
* ''Uncanny ComicBook/{{X-Men}}'' had a example of this trope in #274 and #275 with the Savage Land arc with Magneto and Rogue and the whole Shi'ar arc with the current team roster at the time trying to fight Skrulls. To be fair, this is during Claremont's 1st run which fits with his style.
* Some of the first few issues of the ''ComicBook/TheIncredibleHulk'' that first featured the Hulk's merged personality (A taller green Hulk with Bruce Banner's mind, aka "The Professor") involved this: After the the issue which features Banner's personalities merging the following one focused on what Rick Jones was doing (which in turn formed the framing sequence for a {{Flashback}} story with the Grey Hulk that made up the bulk of the issue). Then the next issue switched things back to the Hulk, and ended with him getting abducted by an organization titled the Patheon. Then the next issue after that focused on Doc Samson getting sidetracked when he visited an assassin he once knew that was currently on death row, with the next two issues then going back and showing what the Hulk was doing with the Patheon.
* The 1997 annuals for ''ComicBook/TheBatmanAdventures'' and ''ComicBook/TheSupermanAdventures'' featured different stories that took place at the same time, involving both Batman and Superman protecting a pair of mystical amulets from different threats. Even the flashbacks in both issues overlapped, showing that Bruce and Clark happened to both be studying under the magician Zatara during the same period.
* Issue 4 of Vision's 2015 series briefly shows Vision talking with his wife while he is fighting Giganto with the adult members of the All-New All-Differant Avengers. At the same time, the teen members are underground searching for Mole Monster in issues 3 and 4 of Nova's 2015 series.

[[folder:Fan Works]]
* As you expect, taking in consideration [[VideoGame/PaperMarioTheThousandYearDoor the source]], ''FanFic/PaperMarioX 2'' and ''Paper Luigi X'' take place at the same time. Team Mario and Team Luigi even meet each other at various points (not to mention Team Luigi meeting with Team BEG at one point). [[spoiler:Team Luigi even gives support to Team Mario in {{the climax}} of ''Paper Mario X 2''.]]
* ''WebAnimation/TurnaboutStorm's'' third part is divided in two episodes: One shows the second day of investigation from [[VisualNovel/AceAttorney Phoenix's]] eyes, and the other one from [[WesternAnimation/MyLittlePonyFriendshipIsMagic Twilight's]]. Both episodes cross twice, showing the same events from a different point of view.
* ''[[http://www.fimfiction.net/story/170261 Twilight Sparkle, Ace Attorney: Turnabout Smiles]]'' also has the second day of investigation seen through two ponies' eyes, in this case being Twilight Sparkle and Star Cestus. Cestus's investigation sequences are similar to the gameplay of ''VisualNovel/AceAttorneyInvestigations'', complete with logic and rebuttals.
* ''Post Nuptials'', first story in FanFic/TheNuptialverse: Except for the first, second-to-last, and last chapters, every chapter happens at roughly the same time (this allows us to get a sneak peek of Spike's chapter in Pinkie's).
** ''Families'' follows three major, mostly separate story arcs focusing on the familial relationships of three groups of characters: Twilight and Spike's [[LikeASonToMe mother-son relationship]]; Rainbow Dash and Scootaloo's sisterly relationship, plus Scootaloo's relationship with her {{abusive parents}}; and Pinkie Pie's relationship with her estranged family.
** ''Directions'' takes place at the same time as ''Through the Mirror''. In the ladder, Twilight and Spike chase Sunset through the mirror in the nuptialverse version of [[WesternAnimation/MyLittlePonyEquestriaGirls Equestria Girls]], while in the former the rest of the mane 6 must learn how to work as a team and protect Equestria without Twilight's help.
* The ''FanFic/RainbowDoubleDashsLunaverse'' stories ''[[http://www.fimfiction.net/story/26552/Family-Matters Family Matters]]'' and ''[[http://www.fimfiction.net/story/33556/Helping...Hands%3F Helping…Hands?]]'' occur around the same time, or at least share a scene where Dinky asks Trixie for help while she has problems of her own.
* ''FanFic/{{Horseshoes and Hand Grenades}}'' has at least ''three'' different stories trying to make sense as to what's going on and they all make references to one another. Most notably, while the majority of ''Horseshoes'' takes place in Kyoto, we have three different sets of protagonists doing different things. ''Month of Sundays'' has many minor Amanogawa High characters getting involved with [[Series/KamenRiderDouble Foundation X]]. ''[=SplitxEnd=]'' has Yayoi researching what caused Horseshoes to go crazy and subsequently meeting up with [[Series/KamenRiderWizard Haruto Souma]], and ''Wheel of Fortune'' is based around Mei's struggles by interpreting fate of different characters and uncovering the story behind [[TheHeavy Yamada Tatsumori]].
* [[FanFic/RainboomsAndRoyalty The Dashverse]]: ''Hot Heads, Cold Hearts, and Nerves of Steel'' briefly follows two different {{Story Arc}}s occurring at the same time -- the Mane Six, Shining Armor, and Cadence on their way to the Crystal Empire to save the foals kidnapped by King Sombra, and Pipsqueak, Alula, and Dinky Doo (later joined by Zecora) in the tunnels underneath Equestria and the Empire. The two groups eventually meet up just before the climax.
* ''FanFic/JusticeLeagueOfEquestria'': ''The Princess of Themyscira'' and ''In Brightest Day, In Blackest Night'' take place at the same time as the second half of ''Mare of Steel''.
* ''[[FanFic/MLPNextGenerationLoveConquersAllAvariceTakesItAll MLP Next Generation: Love Conquers All! Avarice Takes It All!]]'' is split along two plotlines running alongside each other -- Anthea learning to use the Star Sapphire ring while she and Twilight investigate griffon incursions into minotaur territory, and Nidra dealing with the temptations of the Orange ring that's chosen her as its bearer.
* ''[[http://www.fimfiction.net/story/214433 Derpy's Day]]'' takes place during chapter 2 of ''[[http://www.fimfiction.net/story/166077 LEGO Equestria Girls]]'' and focuses on the misadventures of EnsembleDarkhorse Derpy as her head is detached from her body and she attempts to run all over town in order to bring it back. It also expands on a few things that were only mentioned in the main story, such as what Rocky and Mugsy were doing while they had Princess Twilight's crown. It also introduces the concept of "creative marks" to show that this is not just any Lego World: this particular Lego World really is an alternate world to Equestria.
* Madsthenerdygirl's ''[[http://archiveofourown.org/series/782385 MCU Rewrites]]'': ''[[http://archiveofourown.org/works/11613867 New Avengers]]'', ''[[http://archiveofourown.org/works/11613921 Black Widow]]'', and ''[[http://archiveofourown.org/works/11652534 Captain America: Ghosts of HYDRA]]'' all take place at around the same time. The New Avengers (consisting of Sam Wilson/Falcon, James "Rhodey" Rhodes/War Machine, Pietro Maximoff/Quicksilver, Wanda Maximoff/Scarlet Witch and Vision) go up against Sinthea Shmidt/Sin and Viper/Madame Hydra as the two fight for control of the HYDRA organization. Steve Rogers/Captain America has gone on a mission to help his friend, James "Bucky" Barnes/The Winter Soldier and free him from HYDRA's control and as a result the New Avengers do not have him to lead them and he does not have anyone helping him until Maria Hill sends Sharon Carter/Agent 13 to assist Steve. Natasha Romanov/Black Widow is on trial during these events for her past as an assassin from the Red Room which was revealed to the world after she leaked HYDRA and SHIELD to the public in ''Film/CaptainAmericaTheWinterSoldier'' and Clint Barton/Hawkeye is testifying at Natasha's trial.

[[folder:Films -- Animated]]
* Each of the characters stories in ''WesternAnimation/{{Hoodwinked}}''. Red and the Wolf appear to have the most journey overlap. For instance, both of them go through the exact same section of the coal mine, which is one time where they are technically both on screen at the same time but they never see each other (though a FreezeFrameBonus will show the Wolf and Twitchy in the front POV shot from Red's cart going down the drop, and Red's cart dropping in the background when the Wolf and Twitchy are traveling along the mountainside).

[[folder:Films -- Live-Action]]
* One particular scene in ''Film/{{Looper}}'' has Young Joe failing to kill his older self then returning to his apartment to find Gat Men looking for him. He hears a gunshot then traps Boy Blue in his silver vault. Then after a shoot out he ends up falling from the fire escape where he blacks out The scene then flashed to Young Joe actually succeeding in killing his older self, then to a short montage that flashes through 30 years until where Old Joe returns to his past at the point where he escapes in the exact scene that Young Joe fails to kill him. The scene is shot from a different point of view and focuses on Old Joe. Old Joe finds his younger self at his apartment and kills one of The Gat Men (This is the gunshot Young Joe heard) after young Joe falls from the fire escape Old Joe drags him to safety.
* The events of ''Film/SawIII'' and ''Film/SawIV'' are revealed at the end of the latter to be occuring simultaneously.
* The plots of the four main characters in ''Film/FourThreeTwoOne'' are told this way, with onscreen captions telling us what time and day it is so the audience can keep track.
* ''Film/{{Go}}'' employs four simultaneous storylines: one with a group of club kids, one with a drug dealer enjoying a weekend in UsefulNotes/LasVegas, one with a pair of soap opera actors, and one with a narcotics officer. Some stories start earlier, and others finish later, but they overlap and intersect in several places.
* The money drop scene in ''Film/JackieBrown''.
** Likewise, the scenes at the diner that bookend ''Film/PulpFiction''.
* During the racetrack robbery in ''Film/TheKilling'' the perspective of the characters involved in setting up the robbery are shown.
* This is the main conceit of the 2000 drama ''Timecode''. The film (presented as four separate unbroken takes in a single screen) follows several different people, including an actress, her lesbian lover, a casting director and his wife as they go about various activities over the course of the day, and occasionally intersect with one or more of the other arcs.
* In the Franchise/MarvelCinematicUniverse, the events of ''Film/{{Thor}}'', ''Film/IronMan2'' and ''Film/TheIncredibleHulk'' take place during the same week. The tie-in comic ''Fury's Big Week'' also takes place at this time.

* Creator/StephenKing's ''Literature/TheStand'' is mostly told in chronological order and most of the chapters are relatively short. However, in the first half of Book Two, after the Superflu has wiped out 99% of the population, each one of the main characters or group of characters gets their own large chapter all to themselves, detailing their own journey as they cross the United States.
* The Piers Anthony ''Literature/IncarnationsOfImmortality'' books use this trope. The most complete version of this trope is in the sixth book, ''Literature/ForLoveOfEvil'', which shows Satan's view on the events of all the preceding books.
* ''Literature/TheLordOfTheRings'' - The Two Towers portion of the novel is divided up into two segments (as the other two are), the second one detailing the journey of Frodo, Sam, and Gollum to Mordor, and the first segment is about Aragorn and everyone else in the book. The Return of the King does the same thing as well, though not to the extent of The Two Towers. The movie adaptation does away with this and instead uses TwoLinesNoWaiting.
* ''Literature/ASongOfIceAndFire'' - Many chapters occur at the same time as other chapters, and the first 800 pages of ''A Dance With Dragons'' will take place during the same time period as ''A Feast for Crows.''
* In Jean Auel's ''[[Literature/EarthsChildren Valley of the Horses]]'', the chapters alternatively tell the story of, on one hand, Ayla, and on the other, Jondalar and his brother Thonolan as they travel across Europe. Only near the end do they merge as the brothers reach said valley.
* ''Literature/ASeriesOfUnfortunateEvents'' Book the Twelfth. ''The Penultimate Peril'' has simultaneous arcs with each of the three siblings, which is especially confusing when [[spoiler: they each meet one of the twins at exactly the same time]].
* In ''Literature/TreasureIsland'', while Jim Hawkins is on the island witnessing Silver's murder of one of the last loyal crewmen, and then meeting Ben Gunn, three chapters are narrated by Doctor Livesey detailing the departure of the officers from the ''Hispaniola'', the setting of camp in the old stockade, and the death of Tom Redruth. Just as Captain Smollett is setting down to write his log, Hawkins returns and resumes the narrative for the remainder of the book.
* Literature/ForgottenRealms novels of ''[[http://www.o-love.net/realms/head_dia.html Double Diamond Triangle Saga]]'' are even supposed to be read in different order to look at the plots in different ways. Which probably could add a lot given GambitPileup side of the setting -- if writing of the books was not [[http://forum.candlekeep.com/topic.asp?TOPIC_ID=11961#247879 absurdly]] [[ExecutiveMeddling hasted by the publisher]], that is.
* The majority of Literature/{{Elantris}} is set up this way. One chapter follows Raoden, the next shows what Sarene is doing during the same time period, then Hrathen gets a chapter. Then cycle back to Raoden and continue onward with the story. It's not a hundred percent overlap, and the structure breaks down toward the end, but the idea is there.
* The ''Literature/{{Relativity}}'' series:
** Two of the stories, "Highway Robbery" and "A Strange Twist", occur over the same several days but follow different sets of characters. There is some occasional overlap (such as Sara in "A Strange Twist" nearly getting struck by the speeding cars in the [[ItMakesSenseInContext reverse police chase]] that occurs in "Highway Robbery"), and a plot element that occurs in one story ([[spoiler:Ravenswood's wallet getting stolen]]) is wrapped up in the other one.
** There was also the story "Father's Day", which followed three sets of characters over a single day, but there wasn't any overlap between any of them.
** After book 6, there are two major plot threads followed simultaneously. Their chronicles are named "Book 7" and "Book 7½".
* The first three ''Literature/AgeOfFire'' books take place all within roughly the same time period. The first few chapters of each is the same events (from the hatching up until the raid on the egg cave) [[RashomonStyle told from the different points of view of the three main protagonists]]; after that, they split into their own stories, with each subtly influencing the others.
* During the ninth ''Literature/TanteiTeamKZJikenNote'' novel ''The Backyard Knows'', Uesugi [[spoiler:leaves for Switzerland to treat his deteriorating eyesight,]] and come back during the tenth novel, ''The First Love Knows''. The eleventh novel ''The Angel Knows'' is about what happened to Uesugi during his time there; and the author actually notes this novel is chronologically simultaneous to the ninth and tenth novels.
* The first two Literature/{{Torin}} novels, ''The Luck of Brin's Five'' and ''The Nearest Fire'', tell the story of FirstContact between the inhabitants of Torin and a survey team from Earth, from the first inadvertant meeting to the point where the visitors are accepted by society at large. The two novels have different narrators and involve different characters in separate locations, but overlap in time; the second novel begins with an event that's mentioned in passing about halfway through the first, and the end of the first happens about halfway through the second.
* The four "prequel" [[ExpandedUniverse Super Editions]] of ''Literature/WarriorCats'' feature roughly the same timeframe from four different points of view. There are several direct scenes that the books share, sometimes featuring the characters talking to (or at least noticing) one of the others.

[[folder:Live Action TV]]
* Season 4 of ''Series/ArrestedDevelopment'' breathes this trope. The original run did dabble in this, most notably involving multiple Bluths in different cars. In Season 4, each episode follows a specific character through part or all of the period 2006-2013 with several of the same events where everyone's paths crossed covered repeatedly, slowly revealing more of what went on at them.
* ''Series/AreYouAfraidOfTheDark'' did this in the episode "The Tale of the Silver Sight." The Midnight Society was looking for pieces of an old record to solve a mystery, and each member had one piece to find. It would then show one character's arc at a time, and would loop back to the same scene of everybody meeting up in Gary's dorm room, before going back to another person's scenes.
* ''Series/{{Coupling}}'' does this in a few episodes. 9 1/2 minutes (The first of season 4) is probably the most obvious example.
* ''Series/{{Lost}}'' has done this in increasing amounts since season three. Episode 3x01 tells what's happening to Jack, Kate, and Sawyer after the season 2 finale. Episode 3x02 shows what's happening to Sun, Jin, and Sayid. Episode 3x03 shows what's happening back at the beach camp with Locke and others. Season five has delved into this style even further, with some episodes focusing only on those still on the island and others focusing entirely on those who left (though "simultaneous" is somewhat a relative term when time travel is happening.)
** Subverted in the Season 4 episode "Ji Yeon". The audience is first shown Sun in the hospital about to give birth, screaming for her husband Jin. We then cut to a scene of Jin on his cellphone, saying he'll be at the hospital soon. We follow Jin's day as he tries to buy the perfect gift before heading to the hospital. Only at the end of the story do we learn that [[spoiler: the scene with Jin is a flashback to when he was delivering a gift to his boss's client in the hospital, while the scene with Sun was a flash '''forward''', and that Jin could not possibly be at the hospital (Sun screaming for him is thus taken to be hysterical ravings due to the emotional and physical pain of childbirth)]]
* ''Series/{{Battlestar Galactica|2003}}'' did this in Season four with ''Sine Qua Non'' and ''The Hub'', which first showed the Fleet's story, and in the next episode the base star's simultaneous adventures.
* ''Series/{{CSI}}'' "4 x 4" depicts four seperate cases being worked by different members of the cast at the same time. Each segment has a scene connecting it to another case (where its characters are seen in the background), with the first such intersection doubling as ItMakesSenseInContext.
* ''{{Series/Dollhouse}}'' "A Spy In A House Of Love"
* Some of the events depicted from Spike's perspective in the ''Series/BuffyTheVampireSlayer'' episode "Fool For Love" are shown from Darla's in the ''Series/{{Angel}}'' episode "Darla" (which originally aired back-to-back with it).
** Also done in "Same Time, Same Place", when Willow returns to Sunnydale but is invisible to her friends (and vice versa). All scenes in which She, Buffy, and Xander are in the same place is first shown from one perspective, then the other (usually with a clock or section of third party dialogue to orient the viewer)
* This happens in the ''{{Series/Smallville}}'' episode "Promise" (season 6, episode 16), which shows the same day from the perspectives of Clark, Lex and Lana, all of which converge near the end of the episode.
* ''Series/TerminatorTheSarahConnorChronicles'' episode "Mr. Ferguson is Ill Today", the episode where [[spoiler:the protagonists finally succeed in destroying Cromartie's chip]]. One of the more well-done episodes of the series.
* A season 3 episode of ''Series/{{Alias}}'' did this: the first half followed Sydney and Vaughn around, while the second half repeated the first half's events from Sark and Lauren's POV.
* New Zealand's Outrageous Fortune and probably Scoundrels.
* Frequent device on ''Series/HowIMetYourMother''. It was first done in the season 1 episode "Cupcake" with two threads as the group is split between Marshall at a tailor and Lily shopping for a wedding dress. The technique's been used several times since but its more common form in the show was first exhibited in the early season 2 episode "Brunch". In this episode there are three groups rather than two and the contact points before the last one are actually different parts of the same event, as well.
** One of the most memorable usages of this trope appears in "The Burning Beekeeper" where Ted tells the story of Lily and Marshall's party room by room, with the title character running screaming through the house at the end of each one. This remains unexplained until the end of the kitchen segment.'
** "Ten Session" takes place over the course of 10 weeks as Ted talks about his evolving relationship with his dermatologist, Stella, removing an EmbarrassingTattoo. The thing was, a few episodes prior "The Platinum Rule" actually showed the beginning of that story and Ted's first attempt to take Stella on a date. So it can be assumed the episodes in between also happened during this time.
* The ''Series/MalcolmInTheMiddle'' episode: "Blackout" uses this as the episode consists of everyone lying to each other about something and repeats the events several times from a different perspective.
* The Sixth season episode "King Corn" of ''Series/TheWestWing'' shows viewers the same day from the perspective of the campaign workers of the three primary presidential candidates. We first see Vice President Bob Russel's campaign (starting with Donna waking up at 5:46am), then restart the day with Congressman Matt Santos's campaign (starting with Josh waking up at 5:46am), and finally restart again with Senator Arnold Vinick's campaign (starting with the senator himself waking up at 5:46am). Each story follows one campaign through their day, each culminating with that campaign's candidate giving a speech at the Iowa Corn Growers' Expo.

[[folder:Video Games]]
* ''VideoGame/BlazBlueContinuumShift'' has the characters' story routes operate like this.
* The ''VideoGame/{{Siren}}'' games follow this trope nicely, each game consists of around ten different characters experiencing the apocalyptic events simultaneously over the course of a few days and the story is told through snippets of the story told out of chronological order via a little timetable style level selector. Being told like this the story is very hard to follow at times and very disjointing when one minute your playing Kei on 'day 3, 10:00am' then suddenly you're back to day 1 morning. Once you do have a decent handle on the story though it is pretty rewarding.
* ''VideoGame/HalfLife1'' and its two expansions, ''Blue Shift'' and ''Opposing Force'', all take place during the same incident, with different heroes. ''Opposing Force'' has Shepherd's story beginning partway through the original game, but we do get to see what happens at Black Mesa after Freeman is transported to Xen. In ''Half-Life: Decay'' you play as two characters during the events of ''Half-Life''.
* ''VideoGame/ResidentEvil2'' was popular for its two-disc "zapping" system. You'd play through the game with one character, then you could start a NewGamePlus with the other. The game treats the two playthroughs as simultaneous, intertwining stories, and the things you did on the first playthrough affect the world in the second. In addition to this, the events of ''Resident Evil 3'' take place in the same general area, with the events of the second game taking place within the timeframe of the third.
* Most iterations in the ''SonicTheHedgehog'' series, especially from the Dreamcast forward. The original ''VideoGame/SonicAdventure'' is the most fundamental, straight version of the trope, but ''VideoGame/SonicAdventure2'' is particularly notable in that the two stories are actually the opposing sides, not just different shades of heroism.
* ''VideoGame/FrontMission 4'' is played in chapters alternating between two different teams of pilots in completely different locations. The story occurs chronologically, but the characters don't meet until the very final chapter.
* ''VisualNovel/ElevenEyes'' has Cross Vision mode, where the same stretch of time can be revisited from the perspective of another character. Sometimes the events overlap, but a lot of the time a completely different side of the story is being shown. Heroes and villains alike let the player see their side of the story.
* ''VideoGame/KingdomHearts358DaysOver2'' takes place at the same time as ''VideoGame/KingdomHeartsChainOfMemories'' from Roxas's point of view. It starts at the end of ''VideoGame/KingdomHearts'' and not long before the events of ''Chain of Memories'' and continues until just before ''VideoGame/KingdomHeartsII'' when [[spoiler:Roxas fights Riku and loses,]] which then kicks off the prologue of ''KHII''.
** ''Chain of Memories'' also has a mode where you play as [[spoiler: Riku in the castle basement]] instead of Sora.
*** And right after Sora reaches the top of the castle, [[spoiler: [[BookEnds Riku reaches the main/front door of the castle]].]]
** Birth By Sleep features three storylines of the three main protagonists all taking place at the same time with paths of the three converging at times. The final chapter of the story can only be played when all three branches have been completed.
* The first mission of the first ''VideoGame/MedalOfHonor'' occurred at the same time as the mission "Rendezvous With The Resistance" in ''Allied Assault''.
* Pretty much the entirety of ''VideoGame/TreasureOfTheRudra''.
* The initial part of ''VideoGame/SuikodenIII'' is told in chronological chapters from the perspectives of three lead characters who begin in separate locations but frequently interact. Each set of chapters covers roughly the same period of time, allowing you to view some events from multiple perspectives.
* Levels in the ''VideoGame/ModernWarfare'' series love to do this. For example, the entire middle third of the second game alternates between Task Force 141 going after Makarov and the Americans trying to stop the Russian invasion.
* Events in ''VideoGame/GrandTheftAutoIV'' and its [[VideoGame/GrandTheftAutoIVTheLostAndDamned episode]] [[VideoGame/GrandTheftAutoIVTheBalladOfGayTony packs]] are all meant to occur parallel with each other and feature intersecting plot points in different points of view. Examples include Elizabeta's drug deal involving Niko and Johnny, Johnny's theft of the diamonds from a deal involving Luis, Gay Tony and the Cook, and the ambushed deal at The Libertonian involving all three main characters of the games.
** The narrative of ''GTA IV'' and its episodes inspired Rockstar North to expand on the concept of Simultaneous Arcs in the development of ''VideoGame/GrandTheftAutoV''.
* ''VideoGame/AlienVsPredator 2'': The Alien causes infestation of the main MegaCorp base. Marine comes to investigate and inadvertently disables the other base's security, causing the Alien to attack it. The Marine gets captured by the MegaCorp, escapes, and unwittingly frees the Predator who you got captured as earlier.
** in the 2010 game, the Marine character watches the Predator character's ship blow away the ''USS Marlowe'' and fights to the colony, following a distress signal triggered by the Xenomorph character's escape. The stories diverge until the Marine character kills the Xenomorph Matriarch, upon when the Xenomorph character develops into another Matriarch. The Marine then fights Karl Bishop Weyland, while the Predator kills a Predalien and rigs the temple to self-destruct.
* ''VideoGame/OperationFlashpoint'''s Cold War Crisis campaign covers the same conflict from four different character's perspectives, in chronological order. There is a lot of overlap in the events, particularly towards the end. For example, in one mission, where you play as a special forces saboteur, the number of enemy tanks you manage to sabotage is directly linked to how many tanks you face in battle the next day, where you play as the tank commander character.
* ''VisualNovel/{{Remember11}}'' uses this, with the entire story being told first from the perspective of Kokoro, and then restarting from the beginning, seen through Satoru's eyes.
* ''VideoGame/DreamfallTheLongestJourney'' shifts its narrative between three main protagonists, Zoe Castillo, April Ryan, the protagonist of the first game, and the elite Azadi soldier Kian. The three characters cross paths several times throughout the game and end up all coming together to some extent towards the climax.
* Some of the Tortage quests in ''VideoGame/AgeOfConan'' work like this, where different class archetypes do quests giving different perspectives on the story.
* The second ''VideoGame/{{Tenchu}}'' game operates like this. Only by playing through multiple times can you get the full story.
* ''VideoGame/OdinSphere'' has all of the characters' stories take place in roughly the same time. There's even a handy timeline showing all cutscenes and levels together for orientation. All of the arcs lead up to the final epic battle involving every playable character.
* ''VideoGame/{{Fahrenheit}}'' has three protagonists that can come into conflict with each other depending on your choices.
* Several of the character arcs in ''VideoGame/MapleStory'' are clearly happening at the same time as each other. Evan and Aran in particular have very closely related storylines as Evan is tricked into working for the Black Wings while Aran has to clean up some of the messes caused by this.
* Happens a few times in the ''Franchise/SlyCooper'' series in the area climax heist missions of ''VideoGame/Sly2BandOfThieves'' and ''VideoGame/Sly3HonorAmongThieves'', with multiple playable characters rotating through the same part of a mission.
* ''VideoGame/ProfessorLaytonVsPhoenixWrightAceAttorney'':
** Halfway through chapter 3, Phoenix and Layton are forced to split up. Layton has been called to an audience with the Storyteller, and only Phoenix and Maya are allowed to speak with the accused. The following scene takes place from Phoenix and Maya's perspective. After [[spoiler:the beginning of Espella's interrogation, just as she is about to explain why the townsfolk fear her]], the scene shifts to Layton and Luke.
** While the final Witch Trial is in progress, Layton and Luke are looking for final clues [[spoiler:in the Storyteller's room]], so while the majority of the corresponding chapter has you playing as Phoenix during the court sequence, the end of the chapter has you investigating with Layton and Luke.
* ''VideoGame/FinalFantasyIX'': The series of LighterAndSofter events surrounding Garnet, Steiner and Marcus run in parallel to [[CerebusSyndrome Zidane, Vivi and Freya's increasingly grim journey to Burmecia and then Cleyra]] during late Disc One/early Disc 2. They finally converge when [[spoiler:Garnet and Steiner return to Alexandria willingly... but are taken prisoner anyway, Cleyra is destroyed by Brahne, and Zidane and co. use a teleport device to return to Alexandria and rescue Garnet]]. This has the interesting effect of making the BagOfSharing transcend not only space, but ''time'' too, as any items you collect as one party are still present in the other party's inventory, even if you pick up their story at an earlier point in time.
* As it turns out, ''VideoGame/FiveNightsAtFreddys2'' and ''VideoGame/FiveNightsAtFreddys4'' end at the same spot: [[spoiler: the Bite of '87]].
* ''{{VideoGame/Pikmin 3}}'' starts this way, since the S.S. Drake malfunctions shortly before landing causing its crew to be split up. We start by seeing the first day of exploration from Charlie's point of view, then we switch to Alph's point of view as he attempts to locate the S.S. Drake.

* ''Webcomic/TheLawOfPurple'' has a short side arc, focusing on a minor character, set during a major battle. As seen [[http://lawofpurple.comicdish.com/index.php?pageID=716 here.]]
* Usually happens in ''Webcomic/SluggyFreelance'' whenever a main character is trapped in AnotherDimension, or back in time, or in an underground Egyptian tomb (this sorta stuff [[WeirdnessMagnet happens to them a lot]]).
* ''Webcomic/TheOrderOfTheStick'' did a story in which [[EvilTwin Nale]] switched places with Elan; after the switch, Elan and Thog were put in jail, after which the comic followed Nale's infiltration of the Order over about four days of in-story time, leading up to an attempt to murder Haley - at which point Sabine rushes in, and then Elan and Thog crash through the window. The very next strip rewinds to when the twins switched places, but this time follows Elan and Thog as they escape from jail, Elan [[ClassAndLevelSystem literally]] [[TookALevelInBadass takes a level in badass]], and they track down Nale, culminating in them jumping though that window.
* A storyline of ''Webcomic/CollegeRoomiesFromHell!'' does this, following one character at a time over the course of the same week. It's kind of confusing until the end, but awesome nevertheless.
* Book Eleven of ''Webcomic/SchlockMercenary'' involves the crew splitting up to raise money for repairs, but early on, the LemonyNarrator informs us that in seven hundred or so hours, they will be summoned back following an ominous call from Petey to Kerchak. Each of the Toughs' groups then have their own story, with the Narrator frequently butting in to inform us the exact time until the fateful call occurs.
* The last part of the Grace's Birthday Party arc of ''Webcomic/ElGoonishShive'' does this, splitting up the characters into pairs and telling their stories one at a time.
* ''Webcomic/{{Sinfest}}'' often delves into this, most notably the recent separate arcs regarding [[CerebusSyndrome the Patriarchy]], and the developing love story between Criminy and Fuschia.

[[folder:Western Animation]]
* ''WesternAnimation/{{Chowder}}'' "The Wrong Address/The Wrong Customer": During "The Wrong Address" Chowder and Mung see a seemingly insignificant police chase and go about their business. At the end they return home to find it destroyed and Truffles being arrested. In "The Wrong Customer" we find out that the police were chasing an old owl, who causes Mung's place to be destroyed. Truffles being arrested is a seperate but somewhat related matter.
* ''WesternAnimation/PhineasAndFerb'' also did this. One episode had the boys building a bubble type contraption after sending the Fireside Girls to go get some sap. The next episode showed the girls' POV: their adventure as well as that of a different secret agent. This was also done in an earlier episode with the Unfair Science Fair/Unfair Science Fair Redux (the first one focused on Dr. Doofenshmirtz and the second one focused on Candace.) and then a third time with Bee Day and [[{{Pun}} Bee Story]] (again focused on Phineas and Ferb, and then on the Fireside Girls).
* ''TheSimpsons'', "Trilogy of Error": Each of the show's three acts follows Homer, Lisa and Bart respectively as they go on simultaneous adventures, which occasionally cross each other before meeting at the end.
* ''WesternAnimation/SouthPark'' had a three-part meteor showers arc, each episode told from a different point of view: Stan got one, then Cartman got another, and then Kyle and Kenny got one as well. Each episode is completely different and the only thing they have in common is the meteor shower.
* ''WesternAnimation/TransformersPrime'' has the hunt for the Iacon relics arc in season two -- the episodes "Tunnel Vision", "Triangulation", "Triage", and "Toxicity" all happen at the same time. For bonus points, each episode has some scenes set back at the Autobots' base with [[MissionControl Fowler and Raf]], and Toxicity shows all these scenes in context.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** Season 3's, [[Recap/MyLittlePonyFriendshipIsMagicS3E8JustForSidekicks "Just For Sidekicks"]] (focusing on Spike and the Cutie Mark Crusaders) and [[Recap/MyLittlePonyFriendshipIsMagicS3E12GamesPoniesPlay "Games Ponies Play"]] (focusing on Twilight Sparkle and the Mane Six). Implied to have taken place on the same day -- as hinted at by slight overlaps in the storylines at the beginnings and endings of the episodes -- despite being set in different locations and having originally aired a week apart from each other.
** Season 5's [[Recap/MyLittlePonyFriendshipIsMagicS5E17MadeInManehattan "Made In Manehattan"]] and [[Recap/MyLittlePonyFriendshipIsMagicS5E18BrotherhoovesSocial "Brotherhooves Social."]] Applejack and Rarity being summoned to Manehattan is actually what sets up the conflict in Brotherhooves Social.
** The Season 5 finale "The Cutie Remark [[Recap/MyLittlePonyFriendshipIsMagicS5E25TheCutieRemarkPart1 Part 1]] and [[Recap/MyLittlePonyFriendshipIsMagicS5E26TheCutieRemarkPart2 Part 2]]" and ''WesternAnimation/MyLittlePonyEquestriaGirlsFriendshipGames'', although Friendship Games aired several weeks before. During Friendship Games, Sunset Shimmer attempts to contact Princess Twilight Sparkle and ask for her help, but she doesn't respond. Later, after the conflict has already been resolved, Princess Twilight appears and apologizes for not coming sooner, but she was dealing with her own adventure involving time travel, which was then shown in The Cutie Remark.
* The third season of the [[WesternAnimation/TeenageMutantNinjaTurtles2003 second Ninja Turtles]] cartoon featured a five-part storyline where the Turtles were each trapped in a different alternate universe. The first four episodes all had the same beginning that took place from the perspective of a different turtle, and the rest of the episode showed that respective turtle's experience in the world he was trapped in. The fifth and final episode focused on the foursome getting back together.
* ''WesternAnimation/StarVsTheForcesOfEvil'' has "Starsitting" and "On the Job": The first part focuses on Star and Marco babysitting Buff Frog's children while said monster is at work. The second part shows Buff Frog at work while trying to cope with being away from his kids for the first time.
