History VideoGame / ResidentEvil0

* GrapplingHookPistol: Reasonably subverted. The hookshot is quite large (taking two blocks of inventory space to have, similarly to large guns), it can only hold 80kg without getting damaged, and is slow.

** The player can take as long as they like on the speeding train until the sudden urgent need to slam on the brakes appears.

** Just before, Billy has to save Rebecca from falling into a chasm. In order to unlock the door, Rebecca needs to pick up a note that says what the power settings need to be. But, when she falls into the chasm, Billy needs that note, because it hints that [[spoiler:he's got to go through the boiler room]]. So he really shouldn't know that.

-->The weirdest thing about RE0's plot is that it isn't about Billy or Rebecca at all. They've stumbled into the middle of a grudge match between Marcus and Wesker, and by rights, Wesker should be the protagonist. Instead, he's barely in it and you're caught in the fallout.

** Both justified due to Rebecca and Billy being in constant contact via radio. The [[GameplayAndStorySegregation conversations are not actually shown for the most part]], but it's logical to assume they happened. If, every time the characters were separated, the game featured dialogue between them explaining the situation, it would seem too much like [[NarratingTheObvious other]] [[LullDestruction tropes]] since the player knows exactly what's going on. Qualifies as AcceptableBreakFromReality.

* HeroOfAnotherStory: Inverted when you think about it. As pointed out by Tom Wilde's plot analysis, Billy and Rebecca sort of just happened to wander into TheLastDance between Birkin and Wesker and [[spoiler:Dr. Marcus]] and don't actually contribute anything until the very end. In any other context, Birkin would be the protagonist [[VillainProtagonist (albeit an evil one)]] for [[spoiler: blowing up the facility]].

* {{Handguns}}: As usual, the st1aple weapon, though the ones Billy and Rebecca start out with are subtly different. Billy's is slightly more powerful and will randomly headshot zombies, and either gun can be upgraded later on for more power and faster firing.

** Rebecca gets her own when she ''ducks'' through an otherwise typical InsurmountableWaistHeightFence.
*** Billy also ''jumps'' over said fence if you control him when you enter the cable car room

* DeadlyGaze: In the ''HD
Remaster'', Wesker gets this as a special attack in "Wesker Mode", along with his super speed dash. It's not really consistent with his established powers, and was most likely implemented because his super strength punches couldn't be properly animated within the context of the game's engine.

''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 move ''Zero'' from a dying platform to the next generation instead; at the same time, Creator/ShinjiMikami's team began development of a remake of the first ''Resident Evil'', better known as the ''[=REmake=]'', 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=]''. For more than a decade, ''Zero'' was exclusive to Nintendo platforms, as its only port was on the original UsefulNotes/{{Wii}} in 2008. However, on May 25, 2015, Capcom announced the ''Resident Evil Zero HD Remaster'', and it was released for the UsefulNotes/{{PlayStation 4}}, UsefulNotes/XboxOne, UsefulNotes/{{PlayStation 3}}, UsefulNotes/{{Xbox 360}}, and PC on January 19, 2016.

** Believe it or not, the game actually seems to assess your ammo and health upon entering a room and and will allow enemies to be killed much more easily if you're low on health/ammo.[[note]]This isn't the case in Hard mode for obvious reasons.[[/note]]

* SillinessSwitch: Wesker Mode in the Remastered version allows you to play through the entire game with Wesker replacing Billy, and a new black costume for Rebecca. Wesker has a few attacks and abilities unique to him, but real kicker is that all the cutscenes play ''exactly the same'' with just the models swapped, making Wesker act [[http://michibiku.com/wp-content/uploads/2016/01/wesker-resident-evil-0-line.png hilariously out of character]] as Billy.

* WhatHappenedToTheMouse:
** [[spoiler:Billy]] hasn't been heard from in the series since.
** During the third act of the game, captain Enrico inexplicably appears in the underground Umbrella lab and meets with Rebecca, asking Rebecca about Billy (how he even got there is never explained; Rebecca spent two-thirds of the game to get from the train to the lab, and the last time we saw him was in the ''opening'' of the game, in the Raccoon Forest). Enrico then leaves Rebecca, and Rebecca then states that he never saw the captain again after that.

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).

** Rebecca gets her cowgirl ensemble from ''[=REmake=]'', plus a new leather outfit, while Billy gets a fancy suit. Since the closet is located only on the Ecliptic Express, it becomes impossible to change outfits after reaching the Management Training Facility.

* AttackOfTheFiftyFootWhatever: Downplayed, but every single boss other than the Proto-Tyrant and the Queen Leech consists of an ordinary animal grown to a gargantuan stature -- in order, a scorpion, a centipede, and a bat. A file in-game justifies this by explaining that a dramatic increase in stature was the most consistent mutation produced by the Progenitor Virus; more drastic mutation potential was why it was superseded by the T-Virus. It also doubles as a MythologyGag; The original ''Resident Evil'' consisted mostly of giant animals for bosses until the ''[=REmake=]'' added the Crimson Head Alpha and Lisa Trevor.

* TheBadGuyWins: The Mysterious Young Man claims he wants to destroy Umbrella. [[spoiler: By causing the viral outbreak in 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 [[spoiler: getting killed by Rebecca and Billy]].

* BehindTheBlack: Inverted with the leech zombies purely for shock and surprise. There's a few rooms you'll enter and the layout of the room means the leech zombie ''should'' see you as soon as you're in the room, but it won't start attacking until the camera angle changes to show it. At which point, the ScareChord and PsychoStrings start up.

* BossInMookClothing: Mimicry Marcus, a.k.a. the leech zombies. They usually show up in heavily traveled, plot essential areas that also tend to be extremely cramped, and like to come in pairs that occupy adjacent rooms so that the player might run into another one when they run away from one. They pose a serious threat whether you decide to fight them or attempt to run past them. Guns do very little damage, and even molotoves are of limited effectiveness, because it takes three of them to kill just one leech zombie and they have a short range and a long throwing animation. Fire grenades are no stronger, but at least have a longer range.

* DeathFakedForYou: [[spoiler: Rebecca allows Billy to escape at the end by falsely reporting his death.]]

* DoubleUnlock: Getting an E rank in the Leech Hunter minigame, which is as easy as picking up a single leech charm, will unlock bonus submachine gun ammo in the main game. However, actually getting your hand on the submachine gun requires you to beat the main game with either an S or A rank, and you can't play on easy mode.
* EasyModeMockery: Beating the game on easy will not unlock the special weapons.

* EverythingsBetterWithMonkeys: Horribly averted with the Eliminators, who are [[KillerGorilla psychotic albino lab chimps]].

* IWontSayImGuilty: Billy refuses to confirm or deny whether or not he really did commit the murders he was sentenced for. [[spoiler:He didn't. The flashback concerning this issue reveals that it was his commanding officer who was responsible. When Billy tried to stop it, he was knocked out cold. When the massacre was discovered, the unit pinned the blame on him.]]

* KillItWithFire: Flame grenades and molotov cocktails are the best weapons to use against leech zombies; not only do they inflict the most damage, they cause them to die ''without'' exploding.

* TheMedic: Rebecca, as the field medic of S.T.A.R.S is the only one who can combine herbs to make stronger medicine.

* BossInMookClothing: Mimicry Marcus, a.k.a. the leech zombies. They usually show up in heavily traveled, plot essential areas and can follow you to different rooms. They pose a serious threat whether you decide to fight them or attempt to run past them. Guns do very little damage, and even molotoves are of limited effectiveness, because it takes three of them to kill just one leech zombie and they have a short range and a long throwing animation.

In any other context, Birkin would be the protagonist [[VillainProtagonist (albeit an evil one)]] for [[spoiler: blowing up the facility]].

* ScareChord and PsychoStrings: The theme that plays whenever a leech zombie shows up.

* StockVideoGamePuzzle

* ThoseTwoBadGuys: [[MagnificentBastard Wesker]] and [[MadScientist Birkin]], who show up at several points in cutscenes watching the events on the security cameras and attempting to contain the situation.

* TwoKeyedLock: More than a few of these around to take advantage of the partner system, [[spoiler: including the exit.]]

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

* TheWormThatWalks: The leech zombies and [[spoiler:Dr. Marcus himself.]]
