Resident Evil Zero, known in Japan as Biohazard Zero,[a] is a survival horror game developed and published by Capcom. It is the fifth major installment in the Resident Evil series and was originally released for the Nintendo GameCube in 2002. It is a prequel to Resident Evil (2002), covering the ordeals experienced in the Arklay Mountains by the special police force, S.T.A.R.S. Bravo Team. The story follows officer Rebecca Chambers and convicted criminal Billy Coen as they explore an abandoned training facility for employees of the pharmaceutical company Umbrella. The gameplay is similar to early Resident Evil games, but includes a unique "partner zapping" system. The player controls both Rebecca and Billy, switching control between them to solve puzzles and use their unique abilities.

Development for Resident Evil Zero began on the Nintendo 64 in 1998. The partner system was created to take advantage of the short load times possible with the capabilities of the N64 Game Pak. The cartridge format also provided limitations, as the storage capacity was significantly less than that of a CD-ROM. The team had to approach the design differently from previous series entries to conserve storage space. Resident Evil Zero was designed to be more difficult than previous Resident Evil games. Inspired by Sweet Home (1989), the team removed the item storage boxes present in earlier games and introduced a new item-dropping feature. Development slowed when the team encountered memory storage problems, and so production was moved to the newly announced GameCube. The game had to be rebuilt, with only the concept and story carried over.

Resident Evil Zero received generally positive reviews. Critics praised the graphics and audio for building a haunting atmosphere. Opinions on the new partner and item systems were mixed. Some found the changes were an improvement and added new layers of strategy; others believed the changes were cumbersome or non-innovative. The controls were panned as outdated and Capcom was criticized for not evolving the series' tank controls. The game was ported to the Wii in 2008, and a high-definition remaster was released in January 2016. These re-releases received mixed reviews due to lack of improvements made to the original. Resident Evil Zero is commercially successful, having sold over 2.5 million copies across all platforms.


Resident Evil Zero is a third-personsurvival horror video game. The gameplay remains largely the same as previous entries in the series.[3] However, unlike controlling one sole character like the previous games, the player controls two protagonists throughout the entire game. The player may switch between police officer and medic Rebecca Chambers and convicted former Force Reconnaissance Officer Billy Coen. If they travel together, either one of them can be controlled while the other character is handled by the game's AI. The player may also control both simultaneously or split them up entirely to explore areas separately.[3] Each character has unique abilities. Rebecca has a mixing kit which allows her to combine herbs and other chemicals, but she is weak defensively. In contrast, Billy can move heavy objects, use a lighter, and has higher defense.[4][5] The partner system is central to solving many of the game's puzzles.[6]:17

The characters can run as well as perform quick 180-degree turns to evade danger. The player may examine objects such as doors, other characters, and items in order to find clues to proceed through the game. Some objects can be pushed or climbed upon to investigate higher levels.[6]:8 Items held by the characters can be examined in the inventory screen. Some items such as weapons can be equipped, and other items can be combined together to create more effective items or replenish ammunition. When Rebecca and Billy are close-by, they can exchange items between one-another.[6]:10–12 Previous series installments had the player store items in boxes placed in fixed locations. Resident Evil Zero has no item boxes, and instead allows players to drop items on the floor, freeing space in the inventory momentarily until they are retrieved at a later point. The locations of dropped items are displayed on the game map.[3] The number of items that can be discarded in a room is limited.[6]:10–12


On July 23, 1998, an Umbrella owned train, the Ecliptic Express, is attacked by a swarm of leeches while a mysterious young man watches it over a hillside. Two hours later, Bravo Team of the Special Tactics And Rescue Service (S.T.A.R.S.) police force is sent to investigate a series of cannibalistic murders in the Arklay Mountains outside of Raccoon City. On the way to the scene, its helicopter has an engine failure and crash-lands in a forest. Officer Rebecca Chambers of Bravo Team discovers the same train from earlier now infested with zombies and explores it. She teams up with former MarineForce Reconnaissance Billy Coen, a convict on the train, who was being escorted by the military police after he had been sentenced to death for killing 23 people. The two are confronted by the same strangely clad young man from the opening of the game, who sets the train into motion. Meanwhile, two Umbrella soldiers are on the train with them and are taking it to an unknown location while they are being contacted by two supervisors, Albert Wesker and William Birkin. The soldiers are then killed by leeches. As the train speeds out of control, Rebecca and Billy apply the brakes and avert its course towards an abandoned building.

The location is revealed to be a disused training facility for future executives of the pharmaceutical company Umbrella. Rebecca and Billy find out that the corporation's co-founder and former director of the facility, Dr. James Marcus, had discovered the so-called Progenitor virus in the 1960s and examined its potential as a biological weapon. He combined it with leech DNA to develop the t-Virus that causes rapid mutations in living organisms and thus transforms humans and animals into zombies and monsters. Meanwhile, Wesker decides to leave Umbrella and join its rival company. Birkin refuses to join him in order to complete his research on the G-virus. Later, Rebecca and Billy get separated when Billy falls over a railing into the water below. Rebecca, now on her own, encounters Captain Enrico Marini who tells her that the rest of the Bravo team will meet up at an old mansion. He allows her to stay behind to find Billy. Just after Enrico leaves, Rebecca is attacked by the Tyrant. After temporarily defeating the Tyrant, Rebecca meets up with Billy again and together they defeat the Tyrant. After, they lower the dam's water level and continue to navigate the water plant.

Eventually, Rebecca and Billy catch up with the leech-controlling man who is actually Marcus' final experiment, the Queen Leech. A flashback reveals that the real Marcus had been assassinated on the orders of Umbrella co-founder Oswell E. Spencer ten years prior. The Leech entered Marcus' corpse and gained his memories and the ability to shape shift. Now believing itself to be Marcus, the entire outbreak was masterminded by it as a means of revenge. After temporarily defeating the Queen Leech, Billy and Rebecca attempt to take a lift to the surface. The facility's self-destruct mechanism is tripped during the journey, and the two are pursued as they attempt to escape up the shaft. At the top of the shaft, Rebecca and Billy make their final stand against the Queen Leech. Just before the explosion, Rebecca and Billy defeat the creature by exposing it to sunlight. They escape to the forest where they see an old mansion in the distance used by Umbrella as a research facility. Rebecca assures Billy that her police report will list him as just another casualty of the incident. Billy thanks her and escapes as Rebecca heads towards the mansion to investigate the whereabouts of her fellow Bravo Team members, beginning the events of Resident Evil (2002).


While the original Resident Evil (1996) was still in development, the idea for a prequel came up shortly after the 64DD peripheral for the Nintendo 64 was announced in 1995. The 64DD's low sales four years later eventually made Capcom decide to develop Resident Evil Zero as a cartridge-based Nintendo 64 release.[7] Capcom started development on the Nintendo 64 version shortly before the summer of 1998, one of many Resident Evil games being developed at the time. One of these was Resident Evil: Code Veronica (2000) which was taking full advantage of the capacities of the GD-ROM format. The Nintendo 64 cartridge could only store 64MB of data, 1/10 that of a traditional CD-ROM. For these reasons, the team approached Resident Evil Zero with different ideas for gameplay and visual design that would function better with less storage space.[8] After the script had been completed in early 1999, the production of a Resident Evil game for Nintendo 64 was revealed to the public by Yoshiki Okamoto, the president of Capcom's screenplay company Flagship.[9]

Resident Evil Zero was designed to be more difficult than its predecessors, removing the item boxes to make the game more like Sweet Home (1989).[10] The real-time "partner zapping" system was designed to take advantage of the console's unique features and strengths, namely the lack of load times, which are necessary for optical disc based gameplay as with the PlayStation.[7][11] In an effort to make 1-on-1 zombie fights more intense, Capcom experimented with giving the zombies different reactions when they were shot and allowing the player to counter-attack when bitten. The team also toyed with faster zombies, a precursor to Resident Evil's crimson head enemies. The prototype also supported local co-operative play.[8]Resident Evil Zero was officially announced at 20 percent completion in January 2000, after which it was presented with a playable demo at Tokyo Game Show.[12] The game was expected to release in July 2000 and reportedly had an atmosphere close to the first Resident Evil, focusing more on suspense than the more action-oriented gameplay of Resident Evil 2 (1998).[7][13][14] However, development began to slow down when it became apparent that the data for Resident Evil Zero would not fit on a single cartridge.[15]

Production shifted to the newly announced GameCube, with the concept and story carried over but all of the data recreated.[15] The platform change was confirmed in September 2000.[16] The game's final version was developed primarily by Capcom Production Studio 3 with additional support provided by Tose.[17][18] As a result of the transition to the GameCube, it was delayed so that the environments could be upgraded visually.[11] More CGI videos were created as a result of the increased memory capacities, and the voice acting was re-recorded.[7][8] The iconic sounds of the leeches were actually from recordings of cooking hamburgers. For the gun models, the modelling team was provided realistic-looking airsoft guns to base their designs from. Their designs were so close to the source material that the models at-first featured replica markings and gas refill inlets. No one on the team noticed until half-way through development.[19] Scenario writer Noboru Sugimura was called back to make some changes to the story.[20] In the prototype's story, either Rebecca or Billy could die with the other character surviving and completing the game. This idea was scrapped as Rebecca dying would ruin the canon of the Resident Evil timeline.[8] Billy was also originally designed in the prototype as a more ambiguous character, possibly becoming friend or foe as the story progressed. This idea was scrapped.[21] The character designs were also adjusted: Rebecca for example lost her beret and shoulder pads while Billy received a new hairstyle.[22] The GameCube's use of optical discs reintroduced load times, so the programmers had to use sophisticated programming to make the "partner zapping" system work.[11] Capcom announced its intention to release a game demo in Japan around August 2002.[23]


Resident Evil Zero was first released for the Nintendo GameCube on November 10, 2002 in North America, and then later released on November 21, 2002 in Japan and March 7, 2003 in Europe.[24] In December 2008, the game was ported to the Wii along with Resident Evil (2002). The port, Resident Evil Archives: Resident Evil Zero, is near-identical but features a control system that supports the Wii Remote and the GameCube controller.[25] For many years, the fate of the original Nintendo 64 prototype remained unclear. All that remained was low quality video captured from the Tokyo Game Show in 2000 and magazine scans. In 2015, Capcom showed off the prototype while marketing the remaster and demonstrated new high quality footage of it. The prototype remains unreleased to the public.[26][8]


On May 26, 2015, Capcom announced that a remastered version of the game was in development, Resident Evil Zero HD Remaster.[27] The success of the high-definition remaster of Resident Evil inspired producer Tsukasa Takenaka to provide the same treatment to that game's prequel. Takenaka recognized that many Resident Evil fans preferred the old style of gameplay pre-Resident Evil 4, and so he reasoned that the HD remasters were to provide that same gameplay experience on modern hardware.[28] The remaster was produced by Tsukasa Takenaka and the team was made up of many members from the original team, including director Koji Oda. Takenaka was glad Oda was on board, as this ensured Oda's original vision of the game would not be tarnished.[29]Resident Evil Zero HD Remaster was released on January 19, 2016.[30] A retail compilation called Resident Evil Origins Collection that includes Resident Evil HD Remaster and Resident Evil Zero HD Remaster was released on January 22, 2016.[31]

For the remaster, Capcom used the original 2002 models and textures from their archives. To Takenaka's surprise, the models and textures were actually designed in a very high quality, and then downscaled for the original release. This meant that some assets had to be redone, as items that were intentionally blurry or illegible in the original were now much more clear and did not make sense in context, such as posters or signs in the environment.[29] The models and textures were re-touched, and then the backgrounds were re-captured.[32] Some backgrounds in the original also featured video effects such as fire. In the remaster, these videos were transitioned into 3D effects.[19] Additional modes were added as well, including an easy mode and Wesker mode.[19][28] In Wesker mode, the player controls Albert Wesker instead of Billy, and can move quickly and use special attacks. Other improvements include an upgrade to 5.1 surround sound, video options for both the original 4:3 ratio or a new 16:9 option, as well as more control styles including a modern non-tank-like control scheme.[19][33] Overall, Takenaka felt that putting together the remaster for Resident Evil Zero was more difficult than that of Resident Evil, largely due to the companion function.[29]


Resident Evil Zero received generally favorable reviews after its initial GameCube release in 2002.[34] The graphics and atmosphere were universally praised, being described as "wonderfully spooky" and "moody" with an "astonishing level of detail".[3][35][40] Scott Steinberg of GameSpy noted how the animated backgrounds, such as flickering lights and dripping water, brought the environments to life.[41] Giancarlo Varanini of GameSpot shared these sentiments, and complimented Capcom on how they were able to blend the game's models with pre-rendered backgrounds to create highly detailed visuals.[40] The sound design was also complimented, with Matt Casamassina of IGN noting that "Capcom uses silence at times, too, to scare, which is brilliant."[3] Varanini described the soundtrack as one "that will keep you in constant fear."[40] Louis Bedigian of GameZone praised the sound effect work, such as thunder, gunshots, and footsteps for building a scary environment.[42] The controls were universally panned as archaic, and the series was criticized for not evolving the control scheme to something more similar to Devil May Cry (2001) or Eternal Darkness (2002).[3][40][41][39]

Critics had mixed reactions to the gameplay changes from previous series entries. Regarding the new item system, a critic from Game Revolution noted that it prevents the need to return to item boxes to empty inventory. However, he also noted a drawback, in that it introduces more backtracking to pick up an item that was dropped.[39] Contrary to this, Mark MacDonald of praised it for eliminating the backtracking that slowed down previous series entries.[35] Varanini from GameSpot gave credit to Capcom for attempting a new item system, but it is ultimately not too useful since it is easiest to drop all the items in a save location anyway.[40] Casamassina of IGN called the system "perfect" and much better than the item boxes in previous games.[3] Regarding the partner system, Varanini said that it works well, although he found the puzzles too simple and the companion's AI was lacking at times.[40] Bedigian of GameZone praised the companion system for adding a new dimension to the Resident Evil series and it left him excited for future games.[42] Steinberg of GameSpy liked the puzzles which required both characters working together, but he was not keen to fighting alongside them, feeling like he was "babysitting" the other character due to weak AI.[41]

Re-releases of Resident Evil Zero have received considerably less praise than the original, receiving mixed or average reviews.[45][46] The Wii release was criticized for being a near identical port of the GameCube version and for not fully using the Wii Remote's motion control capabilities, instead relying largely on the Classic Controller and remote/nunchuk combo.[47][48] For the high-definition remaster, critics were impressed by the improved visuals but ultimately felt the game inherited the problems of the original.[49][33] Peter Brown of GameSpot highlighted Wesker Mode as a fun addition and noted the game still "bears the hallmarks that made the original Resident Evil enjoyable."[49]

Resident Evil Zero sold 1.25 million copies on the GameCube, and the high-definition remaster has sold 1.3 million units as of December 2016.[50] The game was novelized into the book Resident Evil: Zero Hour by S. D. Perry and published by Pocket Books on October 24, 2004.[51]

On the face of it, the PC version of the Resident Evil Zero HD remaster offers only an incremental upgrade over its companion console releases. The full HD presentation, improved lighting and effects, upgraded character models and optional widescreen mode are joined by a new 60fps mode, plus improved anti-aliasing - but not a whole lot more. But what's fascinating about this release is the contents of its install directory: Resident Evil Zero HD on PC actually give us some idea about how the original game was put together.

However, booting it up for the first time, PC's unique 60fps setting is the most immediate difference to console (though there's an option to match this 30fps experience, plus support for higher values). A game in this style doesn't demand rapid reflexes to succeed; it's Resident Evil in the classic mould, where solving puzzles takes precedent over the action. But even with its fixed camera angles, there's no doubt that Rebecca's motions are smoother at 60fps compared to the locked 30fps on PS4 and Xbox One - a doubling in refresh that's easier on the eye overall.

The exception to this are the backgrounds - and that's where the PC version's install directory is so illuminating in that it shows how the original game worked, and also how Capcom has increased fidelity for the remaster. Divided by folder for each area (such as the Train sequence, Arklay Mountains, or the Chemical Plant) all of the backdrops in the game are actually 30fps video files, available for viewing as an individual MP4s you can watch on any media player. It's here where certain details are gleaned: firstly, that every pre-rendered backdrops animates to one or two second loop. Secondly, that despite the game being output at 1080p on our machine, the actual backdrops are rendered at an entirely different resolution.

A bump to 60fps sets Resident Evil Zero on PC apart from PS4 and Xbox One (which run at 30fps). But looking close at PC, there are a few other changes - while the install directory gives us a fascinating insight into how each scene is put together.

The properties of each file shows that most of the backgrounds (particularly on the train sequence) are stored at an unusual resolution of 1588x1392 - while later spots decode at 1536x1344. Essentially, both values are lower than the 1920x1080 on the horizontal axis - for those playing in 4:3, this means you'll be getting a near 1:1 pixel match on the horizontal scale (with the side portions of the screen boxed out, and the active pixels matching the output resolution). Meanwhile the vertical axis is downscaled from 1392 lines to 1080, which ultimately does the image no harm, and in theory gives a slight super-sampling effect on this axis.

There's a small downside to this: those playing with the new 16:9 mode are filling the width of their 1920-pixel wide screen with a 1588 render. Clarity holds up nicely still in this aspect ratio, but it means that details aren't delivered at a precise match for the full HD standard. As for the extended vertical resolution, the 16:9 mode is designed to pan up and down this space when set to widescreen mode. In practise, with PC running at 1080p, this scrolling effect mitigates the issue when it comes to the unusual vertical resolution.

With this video file as a base, embellishments are added on top in order to bring each scene to life. Backgrounds are 2D by nature but on top of this, Capcom adds polygon-based geometry, such as character models and zombies. Additionally, the remaster's new transparency effects, such as fire and rain, are layered in a separate pass to the foreground or background. As a final composite of all these elements the scene is complete, and in the case of the walk across the train carriage roof, add a great degree of atmosphere to a shot.

In effect, Resident Evil Zero HD on PC runs at two different frame-rates then - the user-definable value set in the options, plus the hard-locked 30fps of the base background files. In the end, having the game animate at two separate rates doesn't distract (the backgrounds are mostly static, after all) but it is a curious hold-over from a different era in game design.

A look at the PC's graphics menu is also insightful. Texture and shadow quality settings are found here (going from low to high) where ultimately PS4 matches both at maximum settings as you'd expect. In direct comparison, both consoles use the exact same background assets as PC, and in every other facet the three versions are identical. Each outputs at 1080p, feature new lighting effects such as bloom, matching shadows resolution, textures, and even the quality of alpha effects in certain scenes.

It's the full deal on console then, though there are some shortfalls. For example, PS4 and Xbox One miss out on PC's superior anti-aliasing modes. There are three on offer in its menu, going from standard FXAA as used on console, to superior FXAA3 and HQ variants - the latter of which deals with the stair-steps on geometric elements, without producing the slight softening effect we see on consoles. PC's presentation of each area is often noticeably sharper as a result, though in effect, it takes side-by-side-comparison to spot.

Also on level terms are the video cut-scenes. In last year's Resident Evil remaster, PC reserved higher quality encodes of each pre-rendered video sequence - reducing the level of compression during fast motion. Unfortunately, the macro-blocking we see in the PS4 and Xbox One assets make their way to PC this time, and there's no higher quality option. The install directory only shows 1080p and 720p encoded instances of each, and in either case the results are softer than we'd expect. It's perhaps the least flattering aspect of this remaster, where the in-game backdrops are treated more care.

Elsewhere, a few other differences are worth mentioning. For one, our SSD-equipped PC regularly showed fewer issues with stuttering in between camera changes. Consoles running on stock 5400rpm HDDs can noticeably hitch as characters meet the edge of a screen, but the issue is evidently minimised on hardware with faster seek times.

Another unusual point is the absence of one specific post-processing effect on PC. In real-time cut-scenes, the maxed-out PC version lacks a depth of field pass on foreground characters, notably on Rebecca as she meets Billy for the first time. It's a simple implementation, and it's surprising to see it missing on any one format, as we do here. It's possible this is an oversight that simply hadn't been corrected by Capcom by release.

Complaints are otherwise few and far between though, and we're pleased with the bonus extras PC owners are privy to - even if they're not complete game changers. It's smoother at 60fps, looks clearer with its better anti-aliasing - though somewhat arbitrarily misses out on one small effect. Taken as a whole, the project is a success on all three formats and PS4, Xbox One, and PC owners can all enjoy a remaster that's high on respect for the design choices of the GameCube original.
