"I know there are purist zombie guys that don't like the running zombies, but I dig the infected thing. I think that's a scarier incorporation of an element into the genre."In quite a few modern Zombie Apocalypse series (and occasionally works about other things that also incorporate Everything's Deader with Zombies), the creator (obviously) wants to have zombies, but would rather not explicitly invoke the supernatural by having them be actual reanimated corpses. This generally happens because it's somewhat more scientifically plausible - at least broadly speaking - that a plague turning infected people into crazed, flesh-rotten cannibals (or slow, lumbering cannibals) could exist in reality than that the dead could rise, so it gets past skeptics' Willing Suspension of Disbelief more easily. Or, as with many works featuring fast zombies, it may be used to justify why they don't act like the classic image of moaning, slowly shambling undead. The virus responsible for zombification may be a mutated version of a real-life disease; rabies is popular because it already makes people and animals act, well, rabid, as is mad cow disease (and prion diseases as a whole) because one major avenue of transmission is by eating infected brain tissue. If the supernatural is involved rather than a virus, but the zombie is living anyway, it's often the result of possession by some nasty entity such as a demon or an Eldritch Abomination. Since they are living people instead of animate corpses, these zombies are almost always easier to kill than the undead kind. They may disregard nonfatal (or not-immediately-fatal) wounds, but anything that would kill a human will kill them. It does run into a bit of a problem if you want a true Zombie Apocalypse, since just like rabid animals they should die of starvation and/or dehydration fairly quickly; even more so if they're zombies that refuse to attack other zombies, refuse to eat dead meat, and will only attack and consume live humans, and aren't shown to seek out water sources. By the time a few weeks have passed, the original zombie infectees should be dead (in the permanent sense) as a lack of resources cause their bodies to fail. This trope is not recommended if you want Earth to be covered in zombies for longer than a month. This is a subtrope of Our Zombies Are Different. It tends to appear alongside Not Using the "Z" Word, but they aren't completely inseparable; zombies-in-all-but-name are often legitimately undead, and Technically Living Zombies are often simply called zombies. The combination of the two has been known to start arguments among zombie fans over whether they're really zombies or not. Which naturally overlooks the fact that the popular, Romero-esque zombies are very different from traditional zombies too, which were basically entranced slaves of voodoo priests, and often very much alive. This trope overlaps with particularly extreme Hate Plagues, but only if the plague causes its victims to act mindless as well as homicidally insane. Usually are a type 3 on the Sliding Scale of Undead Regeneration.

Anime & Manga
- In Barefoot Gen, after the bomb hits, many of the townspeople of Hiroshima that weren't vaporized became so badly burned (and probably disoriented), that they resemble melting zombies... except that they are still (barely) living.
- A story in Franken Fran has an island seemingly suffer an epidemic and the remaining villagers trying to fight off the horde. It turns out its just a mutated fever caused by a parasite that attacks the nervous system giving the subject the appearance of a zombie, but otherwise they were still quite alive, human and aware of what's going on but can't communicate to those unaffected.
- The Crossed are a twisted and nasty version of this. Like the Infected from 28 Days Later, the Crossed are also living people transformed into rage-fueled psychopaths by an unknown malady but unlike them, the Crossed retain human level intelligence and are able to wield weapons, including firearms, drive vehicles, form hunting parties and set up traps to capture victims and torture them in the most unspeakable and creative ways imaginable. They do engage in cannibalism, solely because they are compelled to carry out the most evil thoughts a person can come up with. While the Crossed will mutilate themselves and kill each other out of boredom, they specifically will attack survivors as they cannot get any satisfaction at torturing fellow infected as they will laugh it off whereas seeing a survivor in extreme pain is what they truly seek.
- Bombie the Zombie from the Carl Barks story "Voodoo Hoodoo" isn't an actual zombie. He's under a spell.
- Wynonna Earp: In #4 of the IDW series, Wynonna and the rest of the Black Badges have to deal with a mall full of people who have been transformed into zombies by a Plaguemaster.
- The Newfoals in The Conversion Bureau: The Other Side of the Spectrum are a magical version of this due to a severe case of Getting Smilies Painted on Your Soul. Newfoals feel no emotions other than an artificial happiness, have no will of their own, and will happily throw themselves into the meat grinder on the orders of a native Equestrian. They can also never be returned to the human they once were, as the human's soul is shattered by the potion and bound to Queen Celestia's will, and only death can make it whole again.
Films — Live-Action
- 28 Days Later (and its sequel, 28 Weeks Later) has the Infected, which are living people driven insane by the Rage Virus. The whole movie series is arguably the Trope Codifier. Notably, the Infected do die from starvation and dehydration in about a month, provided they're left alone. Numerous critics have pointed out that pure dehydration will kill a person in a matter of days, though, not weeks. While they do use biting as a method of attack, The Infected are never known to actually devour their victim. Their aim is purely to kill, hence why starvation eventually catches up with them. It isn't clear if the Infected ever attack each other, though they seem to be particularly annoyed at uninfected survivors. The attacks of the Infected are not actually as physically damaging as undead zombies: they're rarely coherent enough to use basic weapons like clubs, but animalistically attack, tooth and nail — they often end up biting and infecting others, but they're not trying to. What really makes them dangerous is that infected bodily fluids are pouring out of all of their orifices, particularly that they regularly vomit up torrents of blood. Simply standing within a few feet of these guys runs the danger of being infected if some of their blood splatters into your mucous membranes.
- Which also makes one wonder how they take weeks to dehydrate when they appear to be constantly bleeding and vomiting.
- There's debate among fans whether the zombies in Zombieland would count. The movie refers to them as undead and some are shown to survive injuries impossible to survive for a human like a shotgun wound in the chest, nevertheless a character in the movie makes a reference of a mutated version of mad cow disease as the cause of the outbreak and some zombies are shown feeding from a trash can.
- The Crazies:
- In the 1973 original, there's a nerve agent airborne virus that turns people into oddly calm psychotics. It eventually either kills them or makes them kill themselves, but preferentially makes them target non-infected they have a grudge on.
- In the 2010 remake, the virus that causes the Crazies, is a modified and weaponized variant of rhabdoviridae, which Rabies is a part of that family of virii; that got into the water supply of Ogden Marsh. It was modified by the US Army at Fort Detrick, with the intention of destabilizing a target population, preferably the enemies'. It was on its way to an incinerator facility in Texas, before a storm caused the plane delivering the virus to its destination; to crash into the swamps around Ogden Marsh. It got into the watershed and ends up contaminating everyone.
- Quarantine directly references rabies. (The original [REC] looks like one of these as well, but ends up going a completely different direction.)
- The infected of Warning Sign become gravely ill and seemingly die, but are actually only going into a short coma before returning as murderous psychopaths.
- The zombies in Dead Air are infected by a chemical agent spread by terrorists.
- The Grapes of Death (Les Raisins de la Mort) is similar to The Crazies, with farm chemicals as the cause.
- I Drink Your Blood depicts an epidemic of rabies.
- The infected in Carriers seem to act like zombies at various points. This is a strange breed because they only live a few weeks before the virus kills them and they maintain higher brain functions. When infected, many try to hide it and latch on to groups of survivors. They don't actively spread the disease, but do so through their infected breath. Most are interested only in themselves, but an infected doctor met near the beginning and a small infected child still have compassion for others (the girl for her immune father and the doctor for any survivors who manage to find him, he even goes as far to kill other infected that come to him).
- The Serpent and the Rainbow uses the original, drugged-and-prematurely-buried voodoo (or at least Hollywood Voodoo) version.
- In Night of the Comet, the "zombies" are humans brain-damaged and warped by partial exposure to the comet's radiations.
- The "zombies" of Teenage Zombies are just poor slobs who have been exposed to a gas that makes them act hypnotized.
- The "zombies" in Nightmare City, also known as City of the Walking Dead, are, um, NOT walking dead at all. They're humans driven insane by a radioactive disaster, who are now driven to psychopathically murder any man, woman or child they see and spread the contamination by mere proximity. However because of their "molecular structure" they are basically immune to bullets and can only die by a gunshot to the head. The main identifier which separates them from normal humans is that their skin shows signs of extreme radiation exposure—burns, blisters, puss the whole nine yards. They seem to drink blood and eat flesh to survive, having lost most higher brain functions, but also seem to still have full motor control, can run as fast as a human, have greater strength and endurance and can use weapons. Not surprisingly, it becomes clear if the contamination spreads it'll mean the extinction of mankind.
- Similarly, the zombies in Cannibal Apocalypse are caused by a disease similar to that which occurs in cannibals who eat infected brains. The virus turns a person into a rabid, psychopathic killer who retains all their normal human brain functions but loses any capacity for lucid thought. They can drive cars, use guns, run as fast as any normal human and—-since, regrettably, many are veterans of an unnamed foreign war—fight and kill with great aplomb. Even worse unlike most Technically Living Zombie viruses, they do not look different than normal, or even lose the ability to communicate, until the virus totally overtakes them and they go insane. The virus was caused by a vet from the war being forced to eat his cohorts whilst held captive by the enemy, causing him to develop the disease and to bring it back with him to civilization.
- In the Dolph Lundgren movie Battle of the Damned, the zombies are also caused by an outbreak of a deadly virus from an illegal laboratory in a South-Asian city. A character even point out that they are not undead, although they are still called "zombies" by everyone. Although one of the robots (yes, there are killer robots too in this movie) mention that they have lower body temperature than non-infected people, and thus quantify them as non-humans. Nonetheless, they are killed as easily as ordinary humans, by drove when it's done by professional soldiers. But they are still fast, and through sheer number they can still overpower even them.
- Spanish sci-fi/horror film The Dark Hour has the Strangers, also infected people that bleed for every orifice but never die and can pass the infection just by touching someone.
- The acclaim German Zombie Apocalypse film Siege of the Dead features infected with rage virus, very similar to 28 Days Later in German version.
- The infected of Pontypool don't necessarily have to bite or even attack to spread the infection. Determining the exact vector by which the infection is spread drives much of the second act. What makes them interesting is that if these infected go for too long without infecting someone, they die, and rather messily at that.
- The infected in the Korean movie Train to Busan also end in this category like a Korean version of 28 Days Later.
- The film adaptation of I Am Legend with Will Smith never uses the Z-word or the V-word, or even the word "undead". The infected (referred to simply as "darkseekers") are alive and is explicitly said to be by the protagonist, who is trying to find a cure for the plague. Apparently, it started with a cure for cancer based on the measles virus, but quickly mutated and became airborne. It is later revealed that one of the antidotes that Neville is experimenting with is actually successful and the infected test subject is beginning to transform back into a normal human.
- His Dark Materials:
- Referenced as a background detail in The Golden Compass. Apparently there's an African tribe which knows how to separate a human from their daemon (soul) without killing the human — just rendering them a mindless, corpse-seeming slave. And it's called a zombi, much like in actual folklore. (This averts the "not supernatural" part of this trope, since this is supernatural from our point of view, and something like mad science in their universe. But, they're not biologically dead.)
- A troop of them show up in a later book; they are still living, breathing, intelligent humans, but lack a will of their own. They're also immune to the soul-eating Specters.
- The zombies from William Bebb's KECK series usually start as this, with The Virus acting as an extreme psychotic Hate Plague in living infected but also reanimating them if they are not killed by brain trauma.
- The "vampires" in the proto-Zombie Apocalypse novel I Am Legend. The majority of infected people are still alive. Some of the vampires are actually undead, but when they infect a person, it turns them into a vampire without killing them.
- The phoners in Cell, who've had all higher brain function blasted away by the Pulse, at least until some new programming kicks in....
- The Forged in the Farseer trilogy are a magic-based version of this, overlapping with The Soulless.
- In Ashes by Ilsa J. Bick, the zombies, or "Changed", are teenagers hit with an electromagnetic pulse that killed most adults, but left them severely mentally impaired.
- In the second book, it's revealed that the zombies are just as smart as humans are, but with a taste for human flesh. They can use weapons such as guns, can communicate with each other but cannot speak, and are intelligent enough to capture humans to eat later.
- In The Maze Runner Trilogy, while Cranks are not ‘zombies’ in the sense of ‘monsters that have died and risen again’, the Flare has eaten away so much of their mental capacity that they have been reduced to animalistic creatures with a taste for human flesh - basically, zombies.
- In the Black Tide Rising series, those infected by the H7D3 virus are still alive in the biological sense, and can starve to death if left without food for sufficiently long time, but in the mental and emotional sense no longer really qualify as human.
- Able Team #8 "Army of Devils" involves a drug which turns gang punks into enraged killers, resulting loads of gorn, the use of excessive firepower and inarticulately growling attackers who need to be shot in the head to be stopped; it's been described by fans as a zombie story masquerading as an action adventure novel.
- The "Clayarks" of the Patternist series are this. The starship Clay's Ark returned to Earth carrying the disease that mutated humans into predatory creatures with heightened physical abilities and an instinctive compulsion to spread the virus. Eventually they destroy civilization, with only the powerfully psychic "Patternists" able to preserve feudal enclaves against constant Clayark attacks.
- Mira Grant's Parasitology series has these in the form of humans infected with a genetically engineered tapeworm that starts out as a health panacea but then Goes Horribly Wrong
- In the novel Blood Pact, a Mad Scientist is reanimating the dead because, well, apparently there is a big push in the academic community to be the first to do so.
- The grown-ups in The Enemy are the victims of an unknown illness, although this doesn't stop the kids from calling them zombies from time to time.
- In Alexei Doronin's Black Day series, some survivors of nuclear attacks (termed "formers", as in "former humans") degenerated to a zombie-like state due to a combination of burns, severe radiation sickness and extreme PTSD (similarly to Barefoot Gen above). Most of them are even violent like zombies.
- The "stone men" in A Song of Ice and Fire are humans in the terminal stage of a dreaded disease known as greyscale. They are mad and violent from a rage virus-like effect, covered in stone-like growths and very infectious.
- The Dinosaur Lords has the hordelings, Raguel's army, who are humans brainwashed down to nothing more than an impulse to kill and eat all non-hordeling humans, behaving much like a Deadly Lunge-utilizing zombies while being as kill-able as humans. How supernatural or how scientific this is is unclear for now.
- The Cleaved of The Witchlands aren't technically dead, but they act like zombies. Fast, superpowered zombies. Fortunately, though, they're Cleaved manually by a Weaverwitch, and don't spread by biting.
- In the Star Trek franchise, all the unnamed Borg drones behave in this way, despite being a part of a very intelligent Hive Mind. Lacking free will or individual self-awareness, the drones' default goal is to assimilate everything they come across into the collective, though they'll ignore nonthreatening people walking around nearby if they have something more important to do. They're like zombies IN SPACE!.
- In one episode of Star Trek: Enterprise, the effects of trellium-D supposedly shuts down Vulcans' emotional control and turns them into paranoid killers. After exposure over many months, the crew Archer and co. meet are shambling around their ship with lumpy skin and mindlessly violent behavior.
- The Reavers in Firefly are like this, though they retain enough intelligence to operate spacecraft, if not very safely. In fact, it's not until the movie that we get definite confirmation that they're this trope -and victims of a really nasty Hate Plague- and not some kind of Ax-Crazy cult.
- The Virus in the Epidemiology episode of Community gives people high fevers that make them act like zombies, complete with spreading via bites.
- On Dollhouse, mind-control technology is used to turn millions of people into mindless killing machines in the Bad Future. (And no, this future is not prevented.) This is one of the few types of zombism that isn't either supernatural or a pathogen, and it's not contiguous in any way. They are simply reprogrammed (via sound waves) people, and they can be reprogrammed back, or at least reprogrammed into something else.
- Sliders had a zombie episode, when the people on a world being infected by mutated bacteria, originally designed to burn fat. Somehow, the infected also gained a sensitivity to light (they didn't burst into flames, but couldn't handle direct exposure to the sun). By the end of the episode, the protagonists manage to find a cure.
- Warehouse 13 had an episode focused on finding an artifact that caused zombie-like symptoms in people.
- The "vectors" in Helix. Super strong, super fast but alive and killable.
- The Primoids in the Doctor Who serial "Inferno" - super-strong, unintelligent and murderous. There is even a sequence where the Doctor is forced to kill a zombified Benton.
- In Supernatural episode "Croatoan" (S02, Ep09), the zombies are transformed by the virus, but do not join The Undead.
- Apocalypse, a Channel 4 special by Derren Brown, takes one unsuspecting volunteer and drops him in the middle of a world where bacteria from an alleged set of meteors that hit Earth has infected a large portion of the UK and then them into "the infected" as part of an Epiphany Therapy.
- In Grimm Zombies can be caused by two things; the Yellow Fever when it affects Wesen causing the Hate Plague effect and by a particular Wesen name Baron Samedi making the classic Voodoo Zombie variety, in both cases the victim is still alive but in no control of his/hers actions.
- As mentioned in the Literature section, the television's counterpart Game of Thrones has the Stonemen as well; crazy infected people acting violently and mindless.
- An episode of Farscape shows an unfortunate Leviathan ship and its Pilot ravage by zombie-like cannibalistic creatures. They are former Sebacean crewmembers made like that by a Mad Scientist.
- Warhammer Fantasy has the Ghouls, who are cannibals from poor lands resorting to eating the corpses of the recently deceased because of their poverty. Whole packs of them gather around Strigoi vampires, who resemble them in both appearance and feeding habits. This is reflected in their rules, where they are considered to be "technically alive" and thus not bound to the army-wide rules that other units have (which includes both perks and handicaps, like not falling apart if the chief necromancer dies, but having to worry about morale). This was discarded for the sixth edition Vampire Counts army book in favor of streamlining the rules (them being subject to morale effects made them somewhat liable in the army, especially when zombies and skeletons are much better for this purpose), though in background terms they are still living creatures (albeit pallid and unhealthy ones), not animated corpses.
- Warhammer 40,000 has the Pariahs, cybernetically modified humans put to use by the Necrons and their C'tan Masters. Like the Ghouls, they were unique in that they did not possess the Necron Rule. Unlike Ghouls, this was a liablity since it made them weaker than actual necrons (no regeneration) and would just plain disappear if the other necron units perished (meaning the enemy can completely ignore the Pariah, which wasn't hard to do since they were combat specialists with no movement modifiers). Less merciful than the Ghouls, they were completely retconned out of existence.
- An old White Dwarf had rules for running straightforward zombies in 40K, listing various forms, including some that were technically alive - people afflicted by Catachan brainleaf or Tyranid cortex leeches, or the victims of an Eldar device that ramped up life force until people with otherwise fatal injuries could be roaming, insane and violent but unable to die.
- There are some variants of this sort in a few of the various worlds of All Flesh Must Be Eaten. Since zombies are there to be slaughtered in AFMBE, and these guys are technically human, the gamebooks including technically living zombies admit that some players might have an ethical problem with killing them, and suggest that the Zombie Master include ways to cure and save the zombies in this sort of situation.
- In Magic: The Gathering, there are Zendikar's nulls, which are basically vampire rejects (Zendikar's vampires are alive, not undead), while Innistrad's skaabs may or may not be undead, as their creation method is seemingly a life-inducing formula (and, accordingly, they are associated with Blue mana rather than the usual Black mana for zombies).
- Dungeons & Dragons:
- 1st edition AD&D has "pseudo-undead": living humanoids who, due to congenital abnormalities, resemble some form of undead, zombies included.
- The 2nd edition module Thoughts of Darkness features enthralled slaves of the Mind Flayers who have the stats of ordinary zombies (including the immunity to mind-affecting spells) but are still alive.
- The nanovirus-infected crewmembers in the Transhuman Space scenario Orbital Decay.
- Those who fail to master the Training from Hell of Ler Drit in Street Fighter but who aren't lucky enough to die burn out most of their minds and souls, rendering themselves in mindlessly violent near-automatons called "Revenants". Master Bison uses them as Cannon Fodder because they don't feel pain, don't think for themselves, have no morals or ethics, and eliminate themselves by erupting into ghostly blue flames that leave only ashes or a scorched skeleton behind upon losing consciousness
- "Undead" in Shadowrun are infectees of the various strains of the Human Meta-Human Vampiric Virus (HMHVV), a magical virus that drains the body of Essence, but leaves the victim clinically alive. HMHVV strain I renders the victim ageless and able to regenerate but in constant need of replenishing their Essence by feeding on the living (by explicitly attacking a living, sentient victim and draining their Essence). Strains II and III re-wires the digestive system to only accept raw metahuman flesh. Again, depending on the strain, agony of infection and other side-effects (the most common strain of HMHVV, creating ghouls, also leaves the victim permanently blind and re-wires their brain into "predator mode") often drives the sufferer "feral".
- Fallout's ghouls are a somewhat different example from the usual strain, because (excluding the ferals, who act like typical zombies) they're basically regular people with a really bad skin condition and effective immortality. It's brought on by being exposed to a huge amount of radiation and not dying from it. And maybe a radiotrophic virus created by the military, depending on what version of the Back Story you believe.
- Fallout: New Vegas brings us two new variants: Marked Men and Ghost People. Marked Men are almost-feral ghouls who inhabit the Divide who constantly have their skin flayed from their bodies but can't die due to the sheer radiation permeating the Divide. Ghost People are the previous inhabitants of the Sierra Madre who got caught in their hazmat suits while trying to protect themselves from the Cloud, with... limited success. Unlike the other quasi-zombies of the series, the Ghost People have a Healing Factor that will continually revive them unless decapitated, dismembered, or disintegrated.
- An aversion are the Lobotomites from Old World Blues, who basically are cybernetically reanimated zombies, having had their brains (and then some) replaced with Tesla implants that allow them to perform basic motor functions and tasks.
- Left 4 Dead's Green Flu doesn't immediately kill its victims. According to promotional materials, it's a mutated strain of rabies. As its name suggests, in the game world it was designated a form of influenza by CEDA, though this was more of a cover-up than anything.
- The disease does prove to be eventually fatal, judging by the fact that a few zombies will collapse on their own. It's also said that children simply die instantly from the disease to explain the absence of child zombies.
- Officially, the victims are called "Infected"; that doesn't stop everyone non-official from calling them zombies and referencing zombie movie tropes. In-universe, the survivors referred to the infected as both zombies and infected.
- The disease does prove to be eventually fatal, judging by the fact that a few zombies will collapse on their own. It's also said that children simply die instantly from the disease to explain the absence of child zombies.
- In S.T.A.L.K.E.R., areas are defended by 'brain scorchers' which strip people of their higher brain functions, turning them into shambling zombies. (Yes, it actually calls them that.)
- Knights of the Old Republic: Rakghouls are horribly mutated monsters that spread via a disease. A single scratch can cause someone to turn. But despite their appearances and ghoulish mannerisms, they are still alive. This becomes a plot point three hundred years later in The Old Republic. The Rakghouls spent the time since the fall of Taris breeding, and are now the dominant life form on the planet. And yet, they still carry the Rakghoul plague and can infect anyone who tries to fight them.
- Knights of the Old Republic II: The Sith Lords: Darth Sion. The only keeping him from death is the pain and hate within him, fueling the Dark Side of the force, and keeping his broken, scarred, decaying body from falling apart. He eventually lets go of the force and dies, after being defeated by the Exile.
- Depending on whether the people taken over by the headcrabs are living Meat Puppets or corpses, the headcrab zombies from Half-Life may or may not count. It's not made very clear, but evidence is in favor of them being alive; corpses probably wouldn't have the inclination to shout muffled but clearly agonized cries for help. Also, when you shoot them in the body, the body will fall down dead, but the headcrab will be perfectly fine, popping off to seek a new victim. Putting it all together does imply the body is still alive in some capacity, although how much intelligence or consciousness they have left is unknown. There's no known way to safely remove a headcrab without killing the body too.
- The Ganados and Majini in the Resident Evil 4 and 5 count, as they're infected with a parasite that takes control of the still-living host. The zombies of earlier in the series were suggested to be this, but the graveyard areas in 3 and Code: Veronica show that the T-Virus does in fact kill and then reanimate.
- Supplementary materials and Word of God say that the zombies rising from the grave were not actually dead, but simply assumed to be dead due to symptoms of the virus and then buried alive. The G-Virus (RE2's final boss) and C-Virus (RE6) are the only ones capable of actually reviving the dead.
- Basic Redlight infectees ("Walkers") in [PROTOTYPE] are for all intents and purposes living zombies; except instead of being mindlessly driven by hunger, they are puppets for their "mother" Elizabeth Greene, or other advanced infectees ("Runners").
- In Psi-Ops: The Mindgate Conspiracy Jov Leonov's mind-controlled Meat Puppets behave in a rather zombie-like manner, shambling mindlessly toward their enemies while ignoring injuries.
- Red Dead Redemption: Undead Nightmare features both living and undead zombies. While the curse reanimated dead bodies, and being bitten by a zombie causes you to turn into one yourself, the process itself does not kill you. This becomes evident at the end of the game, when Marston breaks the curse and the infected zombies revert to their old selves, while the undead ones merely drop dead again.
- In the final level of Deus Ex: Human Revolution, you fight crazies which move and attack like zombies. The zombie-like behavior is caused by hallucinations from the vagus nerve being overstimulated by the biochips implanted in them, which is in turn caused by a signal released by Hugh Darrow in an attempt to show why human augmentation is bad.
- The Zombies in Dead Island are the result of a mutated strain of Kuru (a real disease associated with cannibalism) and the game goes into fair detail about it. Unless you're one of the lucky few who's immune, getting scratched or bitten will infect and turn you within 72 hours.
- What's interesting about the zombies (though game mechanics are partially to blame for it) is that they cannot crawl on the ground. They're instinctively driven to stand up before they attack you. They don't instantly die from a headshot (though humans still do), and even though their blood coagulates and allows them to live with half their chest ripped off, they can still die of blood loss, puke up their own guts in response to poison, and even drown to death in water.
- Most people get turned into what are called "walkers", shambling zombies who are slow to respond to your presence. Some get turned into "Infected", who have no trouble sprinting towards you. The less fortunate are mutated with various degrees of Body Horror. "Suiciders" bloat up with explosively deadly gas. They're still aware of what they are, and moan "Help me" as they approach you, but they're instinctively designed to explode when they get too close to you.
- The worst seem to be the aptly named Butchers. These people are driven into what appears to be a chemically-induced rage, to the point that they've broke the bones in their own arms to fashion into shivs to carve into new victims.
- The Last of Us uses a mutated cordyceps fungus that takes over the brain, making people "infected". While they display the typical traits of zombies, such as an uncontrollable urges to eat humans and the ability to spread their virus through bites, they are indeed still "alive", and thus anything fatal to normal humans will be fatal to them as well. Notably, the developers have said that while the infected are a threat, the primary antagonists are other survivors.
- Husks in Mass Effect, who are captured humans that were forcibly implanted with Reaper technology.
- Mass Effect 3 features that the Reapers have created Banshees, Mauraders, Brutes and Ravagers out of huskified Asari, Turians, Krogan/Turian hybrids, and Rachni, respectively.
- Metal Gear:
- Metal Gear Solid 4: Guns of the Patriots has a local-scale Zombie Apocalypse when Ocelot attempts to disconnect his soldiers from the System that monitors and controls the emotions of all PMC soldiers in the area. The result is brain damage that causes them to mindlessly swarm you in packs, though "mindless" doesn't mean "emotionless" since, if you scan them with the Solid Eye, you can see their emotional states are spiking through the roof—unquenchable anger, hyper-hysterical mad happiness, bottomless sorrow and blinding terror; basically all the emotions their nanomachines were repressing suddenly being reintroduced and overwhelming them. There's even a use of "Not Using the Zed Word" since Otacon calls the zombies "Those... things!"
- Metal Gear Ac!d has Brainwashed "ACUA Troops" who have been overdosed with the drug ACUA and are under the control of a psychic Hive Queen nicknamed "the Mind Bender". These troopers supposedly have only limited emotions and intelligence (they can still be distracted by Books, though) and perception of pain as well as greatly enhanced strength, resistance and bloodlust, and are bad enough that the mercenary leader who hated Snake up until that point is willing to form an alliance with him in the hope of surviving. They are blatantly described as 'zombies' by several of the characters.
- Parodied in Kingdom of Loathing with the "Modern Zmobie" (a "fast zombie"). One of its miss messages has you questioning whether it's actually a zmobie or just a human with a weird diet. It gets too confused to attack you.
- Weepers from Dishonored are late-stage Plague victims, who are described as "Nothing more than moving corpses full of disease and insects." They are accompanied by swarms of flies, and attack by puking on Corvo. However, the game's Karma Meter still counts them as people, so killing them is just as bad as killing a watchman, Overseer, or bystander, taking away from the Guilt-Free Extermination War most games featuring zombies Invoke; this, in fact, ends up justified when one of the possible ending outcomes has a cure developed outright.
- In Saints Row: The Third, an aircraft containing volatile and dangerous chemicals crashes into one of the smaller islands making up Steelport, causing the lethal cargo to be released into the air and turn all the citizens there into zombies. The next mission has the player going there to deal with said cargo, and is slightly affected themselves due to a faulty gas mask, but once they get it patched up they're perfectly fine, and with said cargo pushed into the water the player can travel back there whenever they want with no ill effects (other than being attacked by the zombies, since they continue to infinitely respawn).
- WildStar has the Mordesh, a race of aliens plagued by a flesh-eating, insanity-causing disease christened the Contagion. They are still alive, and rely on Vitalus serum to keep from devolving into the usual flesh-eating Not Zombie. (By the way, they do not like being called "Space Zombies.")
- In The Elder Scrolls III: Morrowind, victims of the Corprus Disease are this. Corprus victims are still living and, in-fact, are The Ageless and have Ideal Illness Immunity. As the disease progresses, their bodies mutate and their mental faculties devolve to animalistic levels, driven to attack those who are not afflicted with the disease. The Nerevarine is technically one of these, as they still have the disease but get the negative effects cured. There are actual undead zombies in the game as well, but they are known as "Bonewalkers" by the Dunmer people. (Elsewhere in Tamriel, they are actually referred to as zombies.)
- In The Adventures of Lomax, the zombies you encounter in the second world are actually lemmings magically turned by Evil Ed into monsters. They are blue and do the Zombie Gait at first, but start running angrily when hit once, and turn back into normal lemmings when you hit them the second time.
- In Dwarf Fortress, husks/thralls are of this sort. Whereas normal undead are reanimated corpses (or parts of one), husks and thralls are converted from currently-living beings by exposure to some of the nastier randomly-generated evil clouds. While this means it can still die (and retains a few conventional vulnerabilities zombies lack), they also retain the skills they had in life, and retain their equipment because they didn't drop it all via dying first.
- The Zombies and Z-Sec in Doom 3 are at least partially comprised of these, since they are created by Demonic Possession and Hell doesn't need its victims to die first before it converts them from humans.
- Dying Light's Harran Virus creates zombies who are still alive, and can be killed through any means that would kill a normal human being. The more mutated Elite Zombie enemies faced in the game are somewhat more difficult to destroy, because their mutations make them tougher than an average person. They still aren't undead, however.
- The Nameless One from Planescape: Torment has Resurrective Immortality that still leaves him with the scars from all of his lives. He is so Covered with Scars that he has no actual skin anymore. His body is so badly ruined that items that normally only work on The Undead work on him.
- In Warframe, the Infested are victims of the Technocyte virus, a highly-virulent plague that twists them into horrific abominations. Most of the time, the process leaves the victim mindless and feral, but a few have been left with their minds intact, albeit subverted by the greater Hive Mind controlling the rest. The virus was apparently created by the Orokin as a weapon against the Sentients, but it failed abysmally and had to be sealed away. Then Dr. Tengus discovered it and tried to weaponize it for the Grineer, only to accidentally unleash it upon the solar system. And most recently, Alad V's experiments with the virus have created a new strain capable of infecting machines.
- The zombies of Zombie Waffe are infected with a new form of rabies which results in fast plague-zombies.
- In El Goonish Shive, "animating the dead" is said to be "impossible" but other" methods are mentioned as ways a "zombie" could be created.
- There's a group of zombies in Sluggy Freelance who were given a very zombielike immortality by black magic, including their bodies rotting at least cosmetically even in the best cases, but never actually died.
- The Zombies from We're Alive need to breath (homemade chloroform knocks them out), eat (they keep piles of flesh from humans and other zombies outside their "nest" at the Arena) and die from wounds other than headshots like shots to the chest or bleeding out from amputated limbs.
- In the CollegeHumor sketch, "The Six Monsters You'll Have as Roommates," the "zombie" is not actually a zombie, but a lazy, messy person (who is probably stoned, sleep-deprived, or both).
- In Spongebob Squarepants many people who were bitten by Gary, though he had mad snail disease, and that it would turn them into zombies. But it turns out that the mad snail disease was just a myth, and they just thought they were zombies because of what Patrick said.
- Smurfs bitten by the gnap fly turn purple and become mindless and aggressive. The condition can be spread to other smurfs by biting their tails.
- In one of The Simpsons Treehouse of Horror special which parodied "28 Days Later", a zombie outbreak started when Krusty made a new burger which was made from a cow that cannibalized another cow. Kent Brockman took a bite out of one and instantly turned into a "muncher", and bit Krusty who started biting other people, soon almost everyone in Springfield were turned into munchers.
- The My Little Pony: Friendship Is Magic episode "28 Pranks Later" has the entire town turned into rainbow mouthed cookie addicts that shamble around demanding more of the dye-bomb cookies that turned them. As the title suggests, it's the nuclear option in a Prank War between Rainbow Dash and the rest of Ponyville.
- The Zoners in Spiral Zone are like this; mindless infected by an artificial plague.
- The Zombies in episode "Scooby-Doo and Cyclops, Too" of The Scooby-Doo and Scrappy-Doo Show are people under the hypnotic spell of The Cyclops, what makes them very aggressive.
- In Real Life, rabies can cause zombie-like behavior because of the brain damage inflicted by the disease. However, it doesn't incubate quickly enough or spread readily enough to cause a Zombie Apocalypse, and the symptoms are somewhat different (most obviously, it doesn't cause the victim's flesh to rot). Also, humans rarely bite each other, even when brain damaged, so human-to-human transmission is largely unknown outside of a few cases of infected organ transplants. On top of that, there is a vaccine, which is always readily available to those bitten. You can even get it before you get bitten, such as if you are a veterinarian, a spelunker, or are going to an area where there will be many wild animals.
- One version of African zombie legends operates this way: living people can be turned into zombies using certain substances. It's commonly believed that tetrodotoxin is used to induce a state of paralysis that resembles death, after which the victim's relatives bury them and the responsible sorcerer digs them up as the toxin is wearing off and slips them a hallucinogenic to make them think they are mindless walking corpses.
- Parasitic fungi in the genus Cordyceps will alter the behavior of the host insect in order to facilitate its own spread. In ants, this behavior is so alarming that any individual exhibiting it is carried very far away from the colony and left to die.
- Cordyceps isn't alone in nature, there are lots of parasites out there that are capable of modifying their host's behavior. And it's not just limited to other animals, some studies have suggested that Toxoplasmosis can cause psychiatric changes in humans that are infected. Granted, it doesn't create zombie-like behavior, but it is certainly possible that there's an organism out there that can.
- Namely, the parasite Toxoplasma Gondii — a parasite mainly found in cats and mice — has been observed in rats to make them seek out places that reek of cat urine, instead of avoiding it like a normal rat. Such behavior would ensure that the rats get eaten by cats with high probability, which would allow the parasites to move on to the next stage of its development, which takes place in cats' digestive tracts. Studies on humans have so far implied that humans infected with it have slower reaction times, and that it possibly can "be a causative or contributory factor in various psychiatric disorders such as depression, anxiety and schizophrenia."
- Rob Zombie is technically alive (and in a possible subversion to the standard cannibalistic tendencies, he is an ardent vegetarian).
- Also, Mark Callaway, a.k.a. The Undertaker; in a case of Life Imitates Art, as he's aged and changed his style and exercise (not to mention injuries) he's gone from bulky and wearing makeup, to wiry and downright creepy looking. Sumbitch even said it in a recent promo spot: "I may look like the walking dead, but trust me, I am still very much alive!"
- On a chemical as opposed to biological vector, the news has (as of 2012) been awash with reports of zombie-like behaviour from the users of a drug colloqially known as "bath salts" — to the point that one user was shot by police while in the middle of feasting on a homeless man. Subverted as the suspect in question was already crazy and it was determined that "bath salts" had nothing to do with the crime.
- It's possible that zombie tropes may be partially rooted in events during The Black Death or similar plagues. Mass graves were used at times, and high fevers can cause delirium or even brain damage. So if someone was buried haphazardly but recovered from the plague enough to free themselves, witnesses would see an inarticulate, clumsy person covered with sores leaving a graveyard, which would look a lot like a "zombie" even when the trope was unbuilt. In fact, plagues and zombies are inextricably linked. If a horror movie starts off on an epidemic, go "All In" on zombies. There may have even been plague victims supposedly "attacking" random people, uninfected or not, though this is all likely due to severe hallucinations and clumsy walking. And of course, no plague-infected people would actually eat people they came in contact with.
- The disease known in Papua New Guinea as kuru. Like mad cow disease, it is caused by a prion (a misfolded protein that causes all sorts of damage). Victims lose their mental capacity, and the disease is characterized chiefly by confusion, malaise, and ataxia. People primarily contracted the disease when they ate deceased members of their tribes as part of their funerary rites.
- The alcoholic drink known as "the zombie" is called this because it is (as its name would suggest) such a strong drink that those who drink it are said to become "zombie-like" (i.e. lethargic and clumsy). The name could also be a reference to the Voodoo Zombie, seeing as the main ingredient in the various forms of the drink is rum. (Actually, several different kinds of rum.) The drink is so strong that the bar where it was invented established a 2-per-customer limit. (Most people, however, can only handle one, if that.)
