History Main / SecretFinalCampaign

* ''VideoGame/ResidentEvil6'': After beating Leon, Chris, and Jake's campaign, Ada's campaign is unlocked. Ada's storyline provides many revelations about what was going on behind the scenes during the main story. This trope is averted in the UsefulNotes/PlayStation4 and UsefulNotes/XboxOne re-release, where Ada's campaign is unlocked from the start.

** ''VideoGame/ResidentEvil2Remake'' has a free DLC called "The Ghost Survivors". It presents three WhatIf scenarios involving characters who died in the course of the main game and the ForWantOfANail that might have saved them (at that moment)[[note]]Robert Kendo receives a radio call that makes him resolve to get to safety just before being DrivenToSuicide after having to MercyKill his family; Katherine Warren manages to overpower and stab Chief Irons before he can murder and taxidermy her; and Ghost, one of the team sent to capture Burkin, who survived G-Birkin's attack decides to make his escape with the last remaining G-Virus sample; although it's implied in the latter case that his survival may indeed be canon[[/note]]. After completing them, a secret fourth scenario is unlocked, where the player must HoldTheLine as Sheriff Daniel Cortini, the officer in the gas station opening sequence (who decided to shoot the zombie which overpowered him when the PlayerCharacter of the main game meets him, instead of restraining it).

** ''VideoGame/SonicSuperstars'' brings this tradition back, where players first start with one story mode. Upon beating it for the first time, Trip the Sungazer, who pulled a HeelFaceTurn and joined Team Sonic in the main game, [[PromotedToPlayable becomes a playable character]] and unlocks her own Story Mode campaign, [[ADayInTheLimelight Trip's Story]], which consists of [[ArrangeMode some remixed levels of the main campaign]] and a new FinalBoss. Once the player has beaten that (along with collected all seven Chaos Emeralds across either campaign), this unlocks Last Story, consisting of a TrueFinalBoss fight against the Black Dragon as Super Sonic.

** ''VideoGame/SonicAdventure2'' starts off with two stories: the Hero story, where you play as Sonic, Tails, and Knuckles; and the Dark story, where you play as Shadow, Eggman, and Rouge. Beat both stories, and you unlock the final story where you play one long level as all the characters (except Shadow), fight a powerful boss using Shadow, and then the TrueFinalBoss as Super Sonic and Super Shadow. Sonic Adventure 2 provides the current page image.

** ''VideoGame/{{Sonic Rush|Series}}'' starts off with just Sonic's story. Upon completing the first zone, Blaze's story becomes available. Beating both stories (and collecting all the Chaos Emeralds in Sonic's story) unlocks one last campaign in which Super Sonic and Burning Blaze face off against a powered-up mech piloted by Eggman and Eggman Nega.

* ''VideoGame/CommandAndConquerTiberiumWars'' features a campaign for each of the two factions, detailing both sides of the Third Tiberium War. Then, midway through the campaign, an AlienInvasion occurs lured there by the detonation of a [[FantasticNuke Liquid Tiberium Bomb]], and after fighting off the aliens and concluding the war for both factions, you are then returned to the menu screen... which promptly assumes control, select "Campaign", which then dramatically reveals the ''third'' campaign, detailing the third side to the Third Tiberium War: that of ''the AlienInvasion itself''.

* ''VideoGame/CommandAndConquerTiberiumWars'' features a campaign for each of the two factions, detailing both sides of the Third Tiberium War. Then, midway through the campaign, an AlienInvasion occurs lured there by the detonation of a [[FantasticNuke Liquid Tiberium Bomb]], and after fighting off the aliens and concluding the war for both factions, you are then returned to the menu screen... which promptly assumes control, selects "Campaign", and reveals the ''third'' campaign, detailing the third side to the Third Tiberium War: that of ''the AlienInvasion itself''.

* In ''VideoGame/PokemonScarletAndViolet'', the player must go through three campaigns while exploring Paldea: Victory Road (the usual Gym challenge path), Starfall Street (fending off the BigBad's evil team), and the Path of Legends (helping Arven procure Herba Mystica from Titan Pokémon) in order to complete the main story...not. Clearing all three campaigns opens up TheVeryDefinitelyFinalDungeon as its own campaign: The Way Home, which involves solving the mystery behind Area Zero.

* ''VideoGame/BlazBlue'': In the first game, you have to finish all characters' story modes in order to unlock the final parts of the whole story. In the second, it's downplayed as you only have to finish certain characters' story modes to do the same.

* A good number of games in the ''VideoGame/SonicTheHedgehog'' series have their stories set up this way. Most of their final campaigns involve playing as Super Sonic and an additional character.

** ''VideoGame/SonicRush'' starts off with just Sonic's story. Upon completing the first zone, Blaze's story becomes available. Beating both stories (and collecting all the Chaos Emeralds in Sonic's story) unlocks one last campaign in which Super Sonic and Burning Blaze face off against a powered-up mech piloted by Eggman and Eggman Nega.

* ''Videogame/CommandAndConquerTiberiumWars'' features a campaign for each of the two factions, detailing both sides of the Third Tiberium War. Then, midway through the campaign, an AlienInvasion occurs lured there by the detonation of a [[FantasticNuke Liquid Tiberium Bomb]], and after fighting off the aliens and concluding the war for both factions, you are then returned to the menu screen.. which promptly assumes control, selects 'campaign', and reveals the ''third'' campaign, detailing the third side to the Third Tiberium War: That of the ''AlienInvasion itself''
* ''Videogame/StarTrekArmada'' is set after the Dominion War at the onset of a [[AssimilationPlot Borg invasion]]. The game features sequential campaigns for the Federation, Klingons, Romulans, and Borg, concluding with [[spoiler: the Borg assimilating Earth while the Klingons and Romulans are distracted fighting each other. During the final mission of the Borg campaign, Picard [[SetRightWhatOnceWentWrong travels back in time]], and a final campaign is revealed where he prevents Borg interference with peace talks and rallies both factions.]]

** ''VideoGame/KingdomHeartsChainOfMemories'' features one of these called "Reverse Rebirth", in which the player is put into Riku's shoes and he has to navigate his own plot. While it is unlocked by ''default'' (thus it is not a "Secret mode" as originally suspected), the player must beat Sora's campaign before they can play it.

* ''VideoGame/LiveALive'': After completing the stories of the seven available characters, an eighth story is unlocked that focuses on a knight named Oersted. Playing through his story will reveal him to actually be the big bad while also giving you one last campaign. In an interesting variant, you can actually choose who to have as the protagonist for the final campaign. There is even a GoldenEnding which involves some exploration. If you choose to have [[VillainProtagonist Oersted as the protagonist]] on the other hand, [[DownerEnding don't expect a happy ending]].

* ''VideoGame/ResidentEvil6'': After beating Leon, Chris, and Jake's campaign, Ada's campaign is unlocked. Ada's storyline provides many revelations about what was going on behind the scenes during the main story. This trope is averted in the Playstation 4 and Xbox One re-release, where Ada's campaign is unlocked from the start.
