History

After the initial Chernobyl Disaster
Chernobyl disaster
The Chernobyl disaster was a nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine , which was under the direct jurisdiction of the central authorities in Moscow...

, attempts were made to repopulate the area, primarily with scientists and military personnel. However, in 2006, almost 20 years after the first incident, a second disaster occurred, caused by the C-consciousness (rus. "О-Сознание" which corresponds with "осознание" - "realisation, awareness") program, killing or mutating most of the inhabitants.

S.T.A.L.K.E.R. begins years later, after people have begun coming to the zone in search of money, valuable artifacts and scientific information.

Mutants

In keeping with the post-nuclear decay within The Zone, extreme radiation has caused mutations among animals and plants in the area. As such, creatures within The Zone are vastly different from their real-world counterparts (which include dogs, boars, crows and many more). Additionally, some areas of The Zone contain mutated humans, the majority of whom were caught in the second nuclear disaster. Several creatures which are present in the game cannot be enabled without game modification.

Artificial Intelligence of wildlife is highly developed and presents many realistic behaviors, such as fights over food and pack mentality, which can be observed in non-scripted events. The game engine was designed so that animal behavior is calculated even if the player is in a different part of the Zone.

Anomalies, artifacts and radiation

As a result of the second Chernobyl disaster, The Zone is littered with small areas of altered physics, known as anomalies. There are several different variations, each one having a unique impact upon those who cross its path. They can be potentially deadly to the player and other NPCs, delivering electric shocks, or pulling them into the air and crushing them. Most anomalies produce visible air or light distortions and their extent can be determined by throwing bolts (of which the player carries an infinite supply) to trigger them. Some stalkers also possess an anomaly detector, which emits warning beeps of a varying frequency depending on their proximity to an anomaly. The guide in the film Stalker

, and his predecessors in the Strugatsky brothers' book Roadside Picnic, test various routes before proceeding. In the film, metal nuts tied with strips of cloth are used.

Anomalies produce Artifacts, the valuable scientific curiosities that make the Zone worth exploring monetarily. As well as being traded for money, a number of Artifacts can be worn so that they provide certain benefits and detriments (for example, increasing a stalker's resistance to gunfire while also contaminating him with small amounts of radiation) although certain rarer Artifacts provide benefits without any negative effects. Artifacts are found scattered throughout the Zone, often near clusters of anomalies.

Radiation caused by the nuclear incidents at Chernobyl occurs in specific invisible patches throughout The Zone. Although most areas in The Zone have no radiation, areas near abandoned construction equipment that was used in the post-accident clean-up, certain military vehicular wreckage and a variety of other locations create fields of radiation of varying intensity and size, some of which cannot be passed through without the proper protective equipment and anti-contaminant agents. In the real world, gas masks, filtration helmets, radiation suits, etc. would be used but in the game world, the equipment is simplified into various sets of armor that have different levels of radiation protection. Additional radiation resistance may be conferred by some artifacts and radiation sickness may be treated by medication or by consuming vodka.

Gameplay

S.T.A.L.K.E.R. is a non-linear

 sandbox game. Players are relatively free to explore the world and have many opportunities to interact with other characters.

S.T.A.L.K.E.R. is primarily an FPS, but also features many RPG elements. The player does not gain additional abilities or statistics like most RPGs, but is instead allowed to use various types of equipment that are either purchased or found throughout the game world. There are a large number of items in the game, so the player has customization choices which are constrained primarily by how much exploring they do.

The game also attempts to blend the story and character interaction which are commonly associated with RPGs. However, unlike RPGs, conversation branches are extremely limited and do not significantly influence the course of the game, aside from accepting or declining missions.

Playing area and travel

The Zone is a large and varied area, consisting of wilderness, human settlements, and several heavily guarded military bases. However, the game world is not a true contiguous world, but rather 18 different maps separated by loading screens. Transfer from one area of the Zone to another can only be accomplished at certain specific passageways; a wire fence border blocks players from attempting to cross the map in any other area.

The game does not feature controllable vehicles (although vehicles are programmed in the game code, they are not available without the use of a third party modification,) and thus players are required to go from place to place on foot. A sprint option using a limited stamina bar can be used to temporarily increase the player's rate of movement, though this is reduced by the weight of objects the player is carrying, and weapons cannot be fired while sprinting. It is possible to sprint indefinitely by using artifacts and keeping below a certain weight limit (50 kg); however, it is impossible to sprint with certain weapons (e.g. RPG-7

 and SVD)

Radiation

When the player enters a highly irradiated area, they will begin to receive radiation poisoning. During this time, a radiation icon appears on the screen and fades through from green to yellow to red, signifying the strength of the poisoning, which grows the longer the player remains present in the affected areas. The stronger the poisoning, the faster the player's health decreases. Unless the player dies from damage caused by radiation poisoning, there are no permanent effects from contracting it other than health loss. However, radiation will persist and continue to drain health until either radiation medication or a substantial amount of vodka is consumed. Radiation can primarily be avoided by wearing certain artifacts that neutralize radiation or more advanced suits that will effectively protect the player from radiation.

Hunger

In much the same way radiation works as a gameplay mechanic, the player will occasionally become hungry during their travels. During this state, an icon of a crossed fork and spoon will appear. Logically, consuming in-game food items returns the player state from hungry to not hungry.

Bleeding

As with radiation and hunger, bleeding is another state of detriment which the player must try to avoid or manage while playing the game. Bleeding occurs when the player sustains certain kinds of injuries of certain severity (such as being shot or stabbed). The player will lose the amount of health determined by the landed blow and will continue to lose small amounts of health as they hemorrhage. Bleeding can sometimes stop on its own, but the player can prevent further bleeding by applying bandages or using first aid kits, thereby preventing further health loss.

Plot

The game offers multiple endings based on the player's choices throughout the game. This section assumes the player achieves the most complete ending.

The game begins with an unconscious, wounded stalker (the player character) being brought to Sidorovich, a black-market trader operating inside the Zone of alienation (or simply "The Zone"). Sid is able to save his life, but the wounded stalker is amnesic

 which contains only one entry in the to-do list: "Kill Strelok." The amnesiac stalker is dubbed "Marked One" by Sid.

Marked One repays Sid by performing certain tasks, and in the process receives information about Strelok's possible whereabouts. With no other leads to his past or the cause of his amnesia Marked One follows the information from contact to contact, tracing Strelok's past movements and learning more about his supposed assassination target; as information is uncovered he begins to recover scattered memories. Eventually Marked One follows a lead to a factory in Yantar. Yantar is the home of a Brain Scorcher, a field which effectively destroys the mind of anyone who comes within its range, turning them violent and hostile. Scientists studying the phenomenon determine that it is man-made and recruit Marked One to enter a secret lab underneath the factory to disable it, which he does.

Information taken from a body in the lab directs Marked One to track down a member of Strelok's group named Doc. Attempting to reach him in an abandoned base of Strelok's, Marked One inadvertently triggers an explosive booby trap

 and is nearly killed, only to be rescued by Doc. While he is incapacitated Doc speaks to Marked One about the rumor of a giant "Wish Granter" artifact located somewhere in the center of the Zone, but also indicates that Marked One is Strelok, calling him by that name. Before Marked One can recover to ask any questions Doc leaves.

Further leads send Marked One towards the Chernobyl Nuclear Power Plant, where the Wish Granter may be located. However, travel to Chernobyl itself has been all but impossible due to the presence of another, larger Brain Scorcher south of Prypiat, as well as the "Monolith" faction of stalkers who worship the Wish Granter and kill anyone attempting to access it. Marked One makes his way through the forest south of Pripyat and deactivates the second Brain Scorcher, re-opening the path to the abandoned city.

Pripyat is in chaos as dozens of stalkers clash with Monolith forces. Marked One eventually makes it to the Chernobyl facility, also held by Monolith forces. After fighting his way through the opposing stalkers Marked One discovers both the gigantic Wish Granter artifact and a secret laboratory in the building. Inside the heavily defended lab is a large holographic terminal, through which an entity calling itself "C-Consciousness" communicates. It readily answers Marked One's questions, revealing what it is, who Marked One is, and the events prior to his amnesia.

; however, these attempts resulted in the unintentional twisting of the physical terrain around Chernobyl as well as the mutation of resident life forms, creating the Zone. In an attempt to hide its existence the C-Consciousness created the two Brain Scorcher fields and erected a Monolith artifact - the Wish Granter - in the center of the Zone, which it uses to brainwash any stalkers who reach it; brainwashed stalkers are tattooed with the "S.T.A.L.K.E.R." acronym and reprogrammed to serve the C-Consciousness.

Rumors of the Wish Granter began to spread throughout the Zone. A group of four stalkers (Strelok, Ghost, Fang, and Doc) attempted to reach the Wish Granter, but after encountering the fanatical Monolith faction they were forced to retreat. Strelok was knocked unconscious during a "blowout" while the others were able to escape. On the way back Fang was killed by a sniper in Pripyat; some time later Ghost was killed in the Brain Scorcher control facility under Yantar.

The unconscious Strelok was discovered by the C-Consciousness; unaware of his identity, it reprogrammed him and mistakenly assigned him the task of killing himself. On the way out of the Zone the truck carrying the still unconscious Strelok was destroyed in a lightning storm and he was discovered by another passing stalker, leading into the events at the beginning of the game.

Once the C-Consciousness has finished answering Marked One/Strelok's questions he is given a choice: merge with the C-Consciousness to ensure its continued existence, or stop the C-Consciousness from continuing its experiments. If Strelok refuses to assist the C-Consciousness he is transported to the exterior of the Chernobyl plant, where he navigates his way through teleportation anomalies and armed Monolith soldiers in order to reach the source of the C-Consciousness. Once inside Strelok shoots the encapsulated scientists which form the C-Consciousness.

Afterward Strelok is shown standing in a grassy field, watching the sky as the clouds break and the sun comes out. The Zone is apparently gone. He questions whether or not he made the right decision, but as he lays down in the grass he concludes that while he may never know what was right, he is happy that he survived.

s have a full life cycle (task accomplishment, combat, rest, feeding and sleep) and the same applies to the many monsters living in the Zone (hunting, attacking stalkers and other monsters, resting, eating, sleeping). These monsters migrate in large groups. The non-scripted nature of the characters means that there are an unlimited number of random quests. For instance, rescuing stalkers from danger, destroying stalker renegades, protecting or attacking stalker camps or searching for treasure. The AI characters travel around the entire Zone as they see fit.

Numerous tactics can be employed to complete the game, such as rushing or using stealth and sniping. The NPCs will react in a different way to each of them. S.T.A.L.K.E.R.'s NPCs plan ahead by "Goal-Oriented Action Planning" to achieve this.

Additionally, hit damage is pseudo-realistic, and the player can die after only being shot a few times (although later in the game various armor suits and artifacts can be acquired that increase the player's resistance to damage).

At the end of February 2009, due to popular demand GSC Game World released "xrCore" build 1935, dated October 18, 2004. It uses a completely different physics engine with many cut monsters, levels, and vehicles. It was also significantly larger than the retail release. It is however somewhat unstable, but features the full game along with a "fully functional ALife system". It is currently available for free download from the GSC servers and mirrors.

 did not find the gameplay particularly innovative, but still complimented the basic FPS design, saying, "S.T.A.L.K.E.R. isn’t the revolution that we all hoped it would be. It is, however, a respectable and sometimes excellent first-person adventure" where as GameSpot called it "one of the best ballistics models ever seen in a game, and as a result, firefights feel authentic as you try and hit someone with what can be a wildly inaccurate rifle".

, Roman Glushkov, Viacheslav Shalygin, and Aleksey Kalugin. A third explosion occurs near Chernobyl in 2051, which destroys the Zone of Alienation along with all the mutants. At the same time, four new Zones appear throughout the former nations of the Soviet Union, separated from the rest of the world by spherical gravity Barriers. These Five Zones are filled with new unseen before technogenic monsters and are connected to each other by areas in the center known as portals. New kinds of stalkers band together to fight off staltechs (former stalkers who have been turned into metallic monsters), mechanoids (machines that have been "reanimated" by extradimensional nanotechnology), other stalker groups, and transnational forces from the outside world who seek to make a fortune on new technology.
