'These creatures ceased being human: they have no cognitive abilities, and so their behavior is the result of whatever remains of their purely animal instincts.'
- Professor Sakharov's explanation on the origins of zombies.

Zombified Stalkers appear in S.T.A.L.K.E.R.: Shadow of Chernobyl, Clear Sky and Call of Pripyat. They are in fact similar to the player, yet brainwashed into attacking him. They do not have any superhuman or mutated abilities, but are unable to talk or to turn back.



Zombies are made by the "Psi Field" given off by psi emitters such as the Brain Scorcher in Lab X-19 and the Miracle Machine in Lab X16; when unprotected Stalkers are exposed to Psi emissions for a sufficient period of time, they start "to lose their minds". This results from irreversible damage to the higher functions of the brain, eventually resulting in a Zombified Stalker.

Zombified Stalkers posess the equivalent intellect of a caveman, add to this a loss of higher brain functions, destruction of pain receptors and loss of most memory and reason, Zombified Stalkers are more like hollow shells or husks of what once was. The fact many Zombies still posess the ability to use weaponry and equipment means that at least on a rudimentary level, some brain functions remain but are gradually lost over time. How zombified stalkers are not killed outright by massive doses of radiation present in every area they are found in however, is still not known.

Stalkers approaching the "Miracle Machine" Emitter of Lab X16 in the factory complex at Yantar reported that once they get close to the gate, they began to hear voices and hallucinate. Following this they felt their brains literally boiling and melting inside their skulls, and they felt weak. If you are lucky enough to get away from the Psi field with your brain intact, you may also suffer from some detrimental side effects of exposure; for example, some Stalkers reported that they temporarily forgot their names after escaping the factory in time. Stalkers from all factions across the Zone may become Zombified, except those from Monolith. Monolithians are an odd case, in that while they display some signs of being zombified, they still retain tactical knowledge and some measure of sentience; it can be assumed that this is the result of their influence by the C-Consciousness.

As seen at the end of Clear Sky's events, Monolith soldiers may be normal stalkers that have been 'indoctrinated' or brainwashed into protecting the C-Consciousness and the Wish Granter. Due to the Brain Scorcher's effects and prolonged exposure to radiation and Psi-Emissions, they may lose control of much of their humanity, and this may explain why many appear to resemble zombified stalkers. Many zombies can be seen wearing Monolith uniforms, which suggests that the process that created them causes long term degeneracy and brain damage and the C-Consciousness brainwashing lasts only as long as the victims mind.

Controllers can also turn hapless Stalkers into Zombies by reaching into their minds and making them lose control of their brains until they become Zombified.


According to Professor Sakharov, these zombie stalkers in turn rely on whatever remains of their animal instincts, such as hunting and feeding.

Zombified stalkers however, still retain their skills to operate mechanical devices, such as firearms although they can't aim it like regular stalkers where they often inaccurately spray-and-pray their weapons from the hip.

Although Zombified Stalkers are still able to use their firearms and even reload them, they are rather stupid, and will often charge right in the middle of a firefight without cover, walking and firing from the hip. Upon encountering zombified stalkers one can hear them murmuring bits of meaningless phrases, establishing that zombies are incapable of coherent speech. In time, the zombie stalker's mind will eventually decay to a point where it will turn into a full fledged Zombie, unable to even operate mechanical devices anymore and rely on their arms and teeth for attacks.

Sometimes one may spot zombified stalkers around a campfire, sticking their hands out towards the fire. This may be a sign that they still hold some form of self preservation. In combat zombie stalkers are most dangerous when they see a target, as their utter disregard for personal safety results in a relentless assault, giving a stalker no time to recover if ill-prepared; in contrast, ordinary stalkers would usually seek cover upon engaging a target. Zombies however, are utterly inaccurate when shooting at long range and so it's most advisable to take them out from a distance. Zombies also have distinctive grey bandages tied around their mouths. Most stalkers seen without a gasmask have similar shrouds over their mouth and noses, as a very makeshift filter against dust, or possibly just to keep warm. In Call of Pripyat, Zombies are never seen wearing gas masks, helmets or even hoods, suggesting they instinctively try and remove anything on their heads.

In Combat

Although they are mindless zombies, Zombified Stalkers are actually quite capable with weaponry and can pose a significant threat, even when one is only facing a small number of them. Despite firing their weaponry from the hip zombie stalkers are quite accurate, especially in large numbers, thus making it inadvisable to get too close for a headshot unless you are undetected. They also seem to be tougher than their normal human counterparts, most likely because they do not feel pain; Zombified Stalkers do not flinch no matter how many times they are shot, and unless they are shot in the head (which does not receive armour benefits), they can easily survive several shotgun shells to the torso, or even 2-3 magazines of assault rifle rounds. Zombified stalkers are sometimes even capable of surviving a headshot with a handgun, though this most usually incapacitates them, requiring either a knife wound or one more bullet to kill. It should be noted, however, that given enough time, an incapacitated zombie will stand back up again. The best way of dispatching zombies is the stereotypical bullet to the head, as the head of any stalker does not receive the defensive benefits that armour gives. Grenades can also be used effectively against zombified stalkers, since they can't run in their zombified state and will not escape the blast. The use of armour piercing rounds may decrease the number of rounds needed to kill a zombie, barring headshots, although considering zombies slow and predictable movement patterns, using armor piercing rounds for body shots is a tremendous waste, as it is by no means difficult to score a headshot.

Though Zombified Stalkers may not immediately react to the player's presence due to slowed reactions and lowered levels of sight and hearing compared to mentally healthy ones, Zombified Stalkers should under no circumstances be ignored if one intends to explore an area in which they are present. In addition, zombified stalkers can very easily turn an otherwise trivial threat such as an aggressive Flesh or mutated boar, into an avalanche of prolonged fire fighting, as they will, just like actual stalkers, react aggresively to the sound of gunfire.

A good tactic, if you want to avoid combat, is to use a rifle and dispatch them from a distance. (A shot to the head will down one) This is especially useful in harder difficulty settings.


Shadow of Chernobyl


Zombified Exoskeleton Expert

Zombified Stalkers can be found predominantly in areas near or next to a Psi Emitter, such as Yantar and Lab X16, the Wild Territory (near the entrance to Yantar), the Red Forest and the Brain Scorcher of Lab X-19, and even Pripyat.

Clear Sky

Zombified Stalkers can be first encountered in the Agroprom Research Institute (near the entrance to Yantar) where the player helps a group of Loners. Later, they can be encountered in Yantar and Red Forest.

Call of Pripyat

Zombified Stalkers can be encountered in all 3 areas of the game (especially after the Blowouts), spawning randomly in every location. Interestingly, if the player grabs the Rough Tools from Sawmill in Zaton without killing the Zombies there, they will become much more common in the game.


  • Although it is said that any stalkers caught in a psy emission will have his brains scrambled and be turned into a zombified stalker, it was never seen in any of the games. In Clear Sky, stalkers will always seek cover, and anyone scripted to stay outside will be removed from the game until the emission is over. In Call of Pripyat, emissions simply kill anyone who happens to be outside during them, except for quest/plot important characters who seem to be completely immune.
  • The zombified stalkers in Call of Pripyat can sometimes be found crouched around a fire pit, murmuring

    Zombified Stalkers "Talking"

    meaningless words to each other, this can be a sign that they still hold some form of humanity, and attempt to communicate with each other. Around barrel fires, they'll stick out their hands into the heat in order to keep warm.They have some kind of life form.
  • Zombies are not actual 'zombies' as defined by popular culture, they are more like husks. Hollow shells of what once was, stripped of reason or thought and turned into mindless slaves. Zombies are basically ordinary stalkers that have been exposed to ungodly amounts of radiation and Psi-waves, and haven't had the good fortune to die. They are technically still alive by medical standards at least, but thier overall conscious behaviour has been surgically removed, replaced by animal instinct, hence - Husk. They cannot be labeled as actual 'undead' because only the brain was affected by the Emission, not the body.
  • In Call of Pripyat, zombified stalkers will even loot weapons and artifacts, and will even use the weapons if they are better than their current weapon. This is why you can sometimes find multiple weapons on the last zombified stalker killed in a horde.
  • Zombies wearing exoskeleton always have mask on their heads in Shadow of Chernobyl, but they don't have one in Clear Sky and Call of Pripyat.
  • They rarely engage in combat with mutants as mutants never seem to attack them. However, under circumstances where high numbers of Zombies come across a pack of dogs or similar highly aggressive mutant, the zombies will open fire if one gets too close. The resulting fight is quite entertaining.
  • They normally carry the same amount of supplies as normal stalkers, although all of the equipment you may find is always weaker than anything the player already has, or is almost always in poor condition. The only things of note they carry is ammunition, bandages, in rare cases anti-rads and medkits.
  • At Yantar, the zombified stalkers to the front of the science bunker will have names just like ordinary stalkers, but the zombified stalkers in the area around Vasiliev's corpse will all have the name "Zombified Stalker". This may mean that the stalkers originally guarding the bunker when the player arrives were Zombified in an Emission.
  • Zombified Stalkers will not attack other humans on sight. They will only attack if others get too close to them. Zombies are however scripted to attack when the player gets anywhere in the area, regardless of location in all three games.
