History VIdeoGame / ResidentEvil0

** Continued in the ''Remastered'' edition, although there are a couple differences. One, you're given a second personal item in the form of a Suitcase, from which you can change costumes at any time right from the start. Second, apart from the three original alternate costumes, there are eight additional costumes available as DLC, not including the novelty T-shirts. Billy is given the option to cosplay as Cody from ''[[VideoGame/StreetFighterAlpha Street Fighter Alpha 3]]'' or a Wolf Force member (specifically Joseph Gibson) from ''[[VideoGame/{{Commando}} Mercs]]'', while Rebecca's outfits are all from other games in the series: her original outfit from the first ''Resident Evil'' (S.T.A.R.S. 1996), her Arrange Mode outfit from ''Director's Cut'' (S.T.A.R.S. 1997), her outfit from the unreleased [=N64=] version of ''[=RE0=]'' (S.T.A.R.S. Prototype), her RPD basketball uniform from the hidden photo in ''[=RE2=]'', her cheerleader outfit from ''Deadly Silence'', and her sexy nurse costume from ''Mercenaries 3D''. The game also adds a "Wesker Mode" that replaces Billy with Wesker and gives Rebecca an EvilCostumeSwitch similar to Jill's in ''[=RE5=]'', the latter of which is unlocked for the main game after completing Wesker Mode for the first time. Rebecca also has twelve novelty T-shirts to choose from, although seven of them are Japanese-only.

* AcademyOfEvil: The Umbrella Management Training Facility. The place basically exists to instill unswerving loyalty to the company and has its students conducting the unethical experiments the company is famous for. Furthermore, this was the school where series villains [[spoiler: Albert Wesker and William Birkin]] got their start.
* ActionGirl: Rebecca, sort of. She's certainly much braver and more capable than her [[DistressedDamsel earlier/later self]] from ''Resident Evil''. Easily justified considering that by ''Resident Evil'', she's been up for a couple days straight and is running on nothing but fear and adrenaline in the middle of a ZombieApocalypse. However, in ''[[VideoGame/ResidentEvilTheUmbrellaChronicles The Umbrella Chronicles]]'', we find out she has at the very least had a nap, albeit a nightmare-filled one.

* TheBadGuyWins: [[spoiler: Marcus claims he wants to destroy Umbrella. By causing the viral outbreak at the Spencer Estate, which ultimately brought attention to what Umbrella was doing, he got exactly what he wanted. He also wants to set the world on fire, which is hard to deny is happening by ''VideoGame/ResidentEvil6'', again in part due to him. The only thing he didn't plan was getting killed by Rebecca and Billy.]]

* BittersweetEnding: [[spoiler: Rebecca and Billy escape from Marcus' facility, killing him in the process, and despite Billy being framed for murders he didn't commit, Rebecca lets him go, taking his dog tags and [[DeathFakedForYou promising to have him declared dead]]. But she's still separated from her squad, her narration outright states [[DoomedByCanon that she never sees Enrico again]], and she's stuck in the middle of nowhere, so her only option is to head for [[VideoGame/ResidentEvil the nearby mansion]] Enrico told her about. [[RuleOfSymbolism Cue a blatantly symbolic shot of a butterfly stuck in a spider web]], [[HereWeGoAgain showing that Rebecca's ordeal is far from over]]...]]

* {{Foreshadowing}}: When you get the the Laboratory, you'll find a photo. If you look it, you can see a tall student that eerily looks like the mysterious figure you kept seeing, who Rebecca or Billy interpret as being Dr. Marcus' son/grandson. [[spoiler:In actuality, it's a young Marcus.]]

* {{Foreshadowing}}: When you get the old photograph in the Laboratory, It's a photo commemorating Jamea Marcus' graduation. If you look in the photograph, you can see a tall student that eerily looks like the mysterious figure you kept seeing. [[spoiler: That is a young Marcus]]. Though Rebecca or Billy interpret him as Marcus' son/grandson, [[spoiler: it isn't]].

* VillainousFriendship: Notes lying around the facility and cutscenes highlight a rare and sincere friendship between Birkin and Wesker as far as Umbrella employees are concerned.

* NintendoHard: This game is comparable to ''[[VideoGame/ResidentEvilCodeVeronica Code: Veronica]]'' as the overall lack of ammo and healing items (that you have to split between two characters) is among the stingiest in the entire series. Unlike that game, however, you do not have a decent knife to help conserve ammo, so you must make every shot count, avoid enemies when possible and only heal when absolutely necessary. If you don't have an excess of ammo for your best weapons and healing items for a boss battle than [[UnwinnableByDesign forget it]]. Have fun starting the entire game over.

* BadassNormal: Billy Coen, a former Marine, is naturally a well-trained kicker of asses. In the ''Zero'' section of ''VideoGame/ResidentEvilTheUmbrellaChronicles'', he uses his handcuffs as makeshift brass knuckles, and is also capable of [[WrestlerInAllOfUs dropkicking a full grown man in the face.]]

** [[spoiler:Billy's unit attacked a village and killed 23 people and they blamed him for it. Since Billy doesn't care about proving his innocence to the point he doesn't confirm or deny to Rebecca if he was involved with the murderers, they got away with it in the end.]]
** [[AvertedTrope Averted]] with Umbrella itself, this game started a domino effect that caused their crimes to be exposed and they were shut down years later, while some like [[Characters/ResidentEvilUmbrellaParamilitaries HUNK and Nikolai]] seemingly got away with their crimes, in general the villains involved with Umbrella were killed off, all because of the consequences of [[spoiler: the Mysterious Young Man's revenge.]]

* VillainousFriendship: Notes lying around the facility and cutscenes highlight a rare and sincere (for Umbrella employees) friendship between Birkin and Wesker.

** William Birkin finally gets some screentime in a non-monster form.
** Billy was originally just a character mentioned in a report by Rebecca in the Nintendo 64 version of ''Resident Evil 2'', who was mentioned to have been killed and turned into a zombie. Here, he is Rebecca's main ally and is revealed [[spoiler:to have been framed for a crime he didn't commit, leading to Rebecca helping him fake his death at the end of the game]].
** James Marcus was first mentioned in a file exclusive to the Nintendo 64 version of ''Resident Evil 2'' where it was stated that he was the scientist responsible for researching the Mother Virus after Spencer discovered it before being fired and his research being continued by Birkin. Here, he is revealed to have been one of the founding members of Umbrella [[spoiler:and was actually assassinated by Spencer ten years prior by Wesker and Birkin, two of his top students]].

* BadassNormal: Billy, a former Marine, is naturally a well-trained asskicker. In ''The Umbrella Chronicles'', he uses his handcuffs as makeshift brass knuckles, and is also capable of drop kicking a full grown man in the face.

* BlownAcrossTheRoom: If the player tries to attack a stinger up close, it will respond by throwing them far away. It will also do this upon death if the player is close.

* DevelopersForesight: In a viciously cruel take, if the player decides to backtrack to earlier areas before the final battle with Marcus, likely to scrounge for supplies, every area in the game is suddenly filled to the brim with zombies that weren't there before or already disposed of prior.

* GameplayAndStorySegregation: In the story, both characters are shown to have working walkie-talkies at the beginning of the game. However, there are certain moments where the player has to do something with one character that will affect the other. Storywise, there is nothing that indicates that Rebecca and Billy relayed any information to each other during these moments.

* ImpaledWithExtremePrejudice: Stinger's fatal strike on players with low HP is to hoist them in place with its pincers and do impale them with its stinger.
* InformingTheFourthWall: Some items have very specific uses. For example, early on there's a room where a character will get trapped in because there's something stuck in the keyhole, and the character mentions they need something sharp to poke it out. The knife doesn't work, and if it's Rebecca, neither does her mixing kit, which is shown to include syringe needles. The only way to open the door is to find an ice pick and give it to the character.

** Billy, a former Marine who just survived going through a water treatment facility's river with a zombie toad, cannot swim across a 3-meter gap of water to get a valve handle.

** [[spoiler:Billy's unit killed a village with 23 people and they blamed him for it. Since Billy doesn't care about proving his innocence to the point he doesn't confirm or deny to Rebecca if he was involved with the murderers, they got away with it in the end.]]

* KnightInSourArmor: Billy.

* PlotHole: Rebecca is bitten, scratched and even swarmed by leeches, but she never contracts the T-Virus. This is not even a case of GameplayAndStorySegregation as it happens during several cutscenes. To make matters worse, there is a file in the game implying that by simply touching a leech will get you infected immediately after. About the only in-universe explanation is that Rebecca is one of the 10% of people that's immune to it. Out-of-universe, it's essentially PlotArmor to make sure she survives intact for the first game.

* SayMyName: Upon [[spoiler:finding Billy limply hanging on to a rock in a roaring river with a lurker sneaking up on him]], it's all Rebecca can do to scream him name several times.

** Getting to Billy, after he's nearly drowned is this.

* VillainousFriendship: Notes lying around the facility and cutscenes highlight a rare sincere, for Umbrella employees, friendship between Birkin and Wesker.

''Resident Evil Zero'', the fifth main game in the ''Franchise/ResidentEvil'' franchise, came out for the UsefulNotes/{{Nintendo GameCube}} in 2002. It serves as a prequel to the original ''VideoGame/{{Resident Evil|1}}''. Creator/{{Capcom}} initially slated this game for the UsefulNotes/{{Nintendo 64}} as a follow-up to that system's port of ''VideoGame/ResidentEvil2'', but scrapped the original version of ''Zero'' halfway through development when Creator/{{Nintendo}} unveiled their next console (the [=GameCube=]). Capcom made the decision to have ''Zero'' MovedToTheNextConsole instead; at the same time, Creator/ShinjiMikami's team began development of [[VideoGame/ResidentEvilRemake a remake]] of the first ''Resident Evil'' for the [=GameCube=]. The development of the two projects overlapped, which led to both games sharing many of the same assets (chiefly the character model for Rebecca Chambers). As a result, development on ''Zero'' finished only a few months after the release of the remake of the first game. For more than a decade, ''Zero'' was exclusive to Nintendo platforms, as its only port was on the original UsefulNotes/{{Wii}} in 2008. However, Capcom released the ''Resident Evil Zero HD Remaster'' for the UsefulNotes/{{PlayStation 4}}, UsefulNotes/XboxOne, UsefulNotes/{{PlayStation 3}}, UsefulNotes/{{Xbox 360}}, and PC on January 19, 2016. A UsefulNotes/NintendoSwitch version was released on May 21, 2019.

* RuleOfSymbolism: [[spoiler: Once Rebecca and Billy finally go their separate ways, the game's closing shot is the infamous mansion from the first game, with a butterfly caught in a spider web imposed on top of it, [[HereWeGoAgain showing that Rebecca's ordeal is far from over]].]]

* ScrewTheRulesImDoingWhatsRight: [[spoiler:Rebecca refuses to arrest Billy, and by the time she manages to reunite with Enrico, she abandons her mission completely to save him. By the end of the game, she's faking his death]].

* KillItWithFire:
** Flame grenades and Molotov cocktails are the best weapons to use against Mimicry Marcus/Leech Zombies; not only do they inflict the most damage, they cause them to die ''without'' exploding.

* CoolTrain: The Ecliptic Express is a ridiculously luxuriant train complete with private sleeping cabins and a restaurant, all to ferry Umbrella employees between Raccoon City and the Management Training Facility, which has to be a couple of hours long trip at best, though in mitigation it is quite possible, nay likely, that the train keeps going after Racoon City, which for a country the size of the USA would excuse the sleeper cabins.
