Clear Sky is a prequel to the events in Stalker: Shadow of Chernobyl.

The player assumes the role of Scar, a veteran Stalker mercenary who was injured and rendered unconscious by an energy emission while guiding a group of scientists through the Zone. Scar, the lone and somehow lucky survivor, is rescued by Clear Sky, a secret and independent Zone faction dedicated to researching and understanding the Zone in order for humanity to better understand what kind of phenomena it is facing. It is not known how Scar survived, but it is noted he has suffered damage to the nervous system and now has an unusual characteristic around him. After becoming familiar with Clear Sky, a patrol at an outpost in the swamps is under attack and Lebedev requests Scar helps them out, especially as some of the men there saved Scar's life. After fighting off mutants keeping the team pinned, a second emission suddenly occurs. Scar is once again the sole survivor, recovered shortly after the emission died down. The leader of Clear Sky, Lebedev, is amazed by how Scar is still alive. The Clear Sky lead researcher, Chebekov, believes Scar has acquired some "unusual ability" that allows him to navigate and survive anomalies and parts of the zone that would practically kill any ordinary man. Lebedev begins to theorize that the Zone is being disrupted by a dramatic increase in energy emissions, emanating from the Chernobyl power plant in the center of the Zone. Human activity is believed to be the cause. In other words, the emissions are part of an "immune response" the zone has. Someone has made it to the center of the zone, which is supposedly "meant to be taboo" and the zone itself is trying to consume that person in order to preserve its secrets. Besides endangering all the Stalkers in the Zone, Scar is heavily at risk too, already badly damaged by both previous emissions. Every emission harms the nervous system and future ones will eventually kill him if they continue. If the irregular and dramatic increase of emissions continues, the zone could eventually become highly unstable and run out of control, which may have disastrous and unknown effects for the zone and the outside world.

Scar is tasked with finding out about any activity regarding Stalkers trying to reach the center of the zone. The only piece of information he has to go on at first is that an unusual group of Stalkers were talking to the trader, Sidorovich, in the Cordon, the southern boundary of the zone. After assisting Clear Sky forces regain control of the swamps, Scar makes his own way to the Cordon, where he is contacted by Sidorovich. Narrowly escaping the Military outpost next to his entry point, Scar meets Sidorovich, who knows a great deal about what is happening in the Cordon and have met the stalkers Lebedev mentioned. He doesn't see a reason to stretch his memory about them until Scar asks if there is something that would make him talk. Sidorovich likes the idea of "talking business" and discusses his problem. Certain events have caused Loners and Military to turn on one another. The result makes a case of loot that the Loners were meant to deliver go missing. It doesn't do well for Sidorovich, as "the client is rare and the loot is rather unique". The deal is that if Scar can find and bring the case, Sidorovich will be shed some information about the stalkers. This can only be achieved if Scar co-operates with the Loners. As the leader Valerian reveals, Loners and the Military were fighting because the Loners were being double-crossed and ambushed by bandits, who were given locations of Loner activity. The only thing preventing them from being destroyed by the main brute of the Military is the captured commander, Kheletsky. He can't be set free and he can't be killed either. When Kheletsky refuses to reveal the location, Velarian believes that they need to eliminate key forces who would attempt to rescue the commander. Doing this will force Kheletsky to crack. He eventually gives in and reveals the location of the case, which Scar collects and brings to Sidorovich.

Sidorovich, thanking Scar for bringing the case, is now willing to satisfy his end of the deal. He explains that the group that visited him were looking for some exotic parts he did not have in store, notably one of the members, Fang. Fang bought what he want from Sidorovich and when asked where to find the other parts he wanted, he was directed to the Garbage, where piles of old relics and unwanted objects similar to the request could be found. Scar heads to the Garbage to try and find Fang, but stumbles along a PDA belonging to a team that Fang double-crossed. After saving the messenger of the group who was pursuing, it is said that Fang ventured alone into the Dark Valley. Scar heads to the Dark Valley to find the Freedom faction, trying to control the area from mysterious attacks and losses of numbers of comrades. When Scar helps Freedom in order for information about Fang, he finds that mercenaries are being sent upon Freedom by a renegade commander who is attempting to flee. Scar helps Freedom deal with the mercenaries and the renegade commander, eventually clearing out their base of operations at an abandoned factory. To fulfill his end of the bargain, the Freedom leader tells Scar that Fang returned to the Garbage shortly after visiting the base for the parts he needed. Scar gets pointed to the Flea Market back in the Garbage and departs, hot on Fang's trail.

When he reaches the basement of the Flea Market, he is ambushed and is rendered unconscious by bandits. The bandits had laid the trap for Fang, in which they failed to stop him fleeing, now catching Scar instead. They care not about Fang, saying that he dropped his equipment and that's all that matters. They take Scar's equipment and run, leaving Scar alone. Lebedev hails Scar via PDA and tells him Fang's PDA is nearby. Upon discovering it, Lebedev's suspicions are correct. A message to Fang reveals that his friends are aware someone, assuming Clear Sky or Scar, knows that they've been to the center of the zone and there's a change in plans, which are detailed in a stash hidden in the Agroprom underground. Lebedev confirms that they are the ones the zone is trying to destroy, but its not clear how they got past the Brain Scorcher or why exactly they are doing this. Nevertheless, Lebedev reaches a conclusion. Either Fang and his friends are stopped or the zone will run out of control. Scar is tasked to pursue the team by any means possible. Before that, Scar will need to recover his equipment from the bandits who stole it, which is a difficult task as he has nothing to protect himself with except a leftover pistol.

He travels to Agroprom Institute, which is in the hands of Duty, the rival of Freedom. If Scar allies with Freedom, he will find it harder to complete this part of the plot. The zone is being overwhelmed by very dangerous mutants and the commander of Duty is hard pressed trying to remove them. When it is found that Fang went to the underground, Scar volunteers to head into there and rout out the mutants as a way to return the favour of information being spilled. Battling through mutants and bandits, he discovers the stash mentioned from the Flea Market. The log contains a recording from Strelok, the protagonist of Shadow from Chernobyl. His team, comprising of himself, Fang and Ghost, are going to head to the NPP once again, directly through the Brain Scorcher, in order to reach the Wish Granter. Their intentions clear, Lebedov gives Scar the undeniably difficult task of killing Strelok before he reaches the center. While Scar pursues him, Clear Sky will ambush and stop Fang and Ghost. After escaping the underground, it is time for the travel north, in which many obstacles await.

The first problem is in Yantar, a Loner dominant zone. The factory near the science bunker is swarming with hordes of zombies, ordinary people whose brains have melted due to a powerful psi field there. Professor Sakharov, who is operating in the area tells Scar that Strelok had passed through the region. While in Yantar, he volunteered to test a prototype device. In return, Strelok was allowed to keep the finished product. The device itself would allow the user to completely resist and block psi emission effects, like the Brain Scorcher. To help with the zombie problem, Scar locates a dead group of dead stalkers who were moments ago alive near the plant, with acquired notes about a cooling device in the plant designed to reduce psy emissions. However, the unstable field of recent is due to a failure in the system. In order to proceed, it needs to be repaired so that the psy emissions around the factory cease. Scar teams up with a Loner named Lefty and his crew who battle through the Zombie hordes and restart the coolant pumps inside the factory. Without the emissions, there should be no more problems. Professor Sakharov thanks Scar for his aid before informing him that a signal from the prototype device is being detected. According to the signal, Strelok is in the Red Forest. Scar quickly proceeds forward.

Strelok is directly in plain sight. Lebedev hurries Scar to stop Strelok, who responds with threats of death if the pursuit did not cease. After chasing him to a motorized bridge, an ambush springs from hired Loners and Scar must fend it off. Strelok takes advantage of this and is the sole escapee, blowing up a tunnel behind him. He assures Scar that it is no longer possible to follow him and clearly states that he will reach the center whatever it takes. Lebedev makes contact again. The tunnel was the quickest way to the plant, which is through the Brain Scorcher. The only possible way now is through Limansk, on the other side of the bridge. Lebedev tries to think of a way to reach the other side so. The bridge is raised, is sitting over highly radioactive water and controlled by bandits, who guarded the operating console. Scar is directed to an old Forester in the Red forest, protected by Duty, who may know a way. Forester is regarded as a famous guide in these parts, who can literally discover safe parts in areas he has never been in before. Upon meeting Scar who navigates the forest, he tells Scar he knows of a way. A group of Stalkers and Mercenaries, guided by a man called Leshiy, were attempting to reach the other side but ended up in a spatial anomaly, effectively trapped somewhere near Limansk. They are unable to escape, as any attempts only brings them back at the start. To help them, Scar visits a group of Mercenaries aligned with Leshiy at the ravaged Military warehouses, who reported some radio transmissions appearing near a tower. When Scar arrives, he hears what is happening to the trapped group in the Spatial Anomaly. He then helps in recovering a unique artifact for Forester which enables him to navigate the zone. Forester believes it could to used to help guide the team out of the anomaly. One task remains. Scar must deliver co-ordinates to the group that will free them from the anomaly.

Scar is directed back to the military warehouses, where he reunites with the mercenaries. They know of a military radio transmitter which is powerful enough to transmit the needed coordinates to Leshy's team. Unfortunately, it is guarded at a base by what is believed to be the last of the Military. The Military have been reduced significantly down to a few squads because they could no longer hold the barrier. The leader, Hog, pairs Scar with Kostian, a freedom stalker leading an attack squad who are making a raid at the same place and owes Hog for being rescued weeks ago. After fighting heavy resistance at the base, Scar powers up the transmitter and waits as Leshy and his team is freed. They are now on the other side of the bridge. Lebedev acts on this action. Convincing Leshy and his team to aid Clear Sky in reaching the other side, a large contingent of Clear Sky soldiers head to the bridge, awaiting Scar's arrival so they can make a push. When he does get there, he assists Lebedev and the Clear Sky forces to provide cover from bandits for Leshy's team while they lower the bridge. After a heated battle, both sides succeed and share their gratitude. Clear Sky then begins to make the push through Limansk. Lebedev tells Scar to join the first advance team and spearhead the charge.

The pressure is on at this stage. Limansk has been turned into a street war between bandits, remaining Military forces and, if Scar did not encounter them at the barrier in the Military Warehouses, Monolith. Clear Sky helps Scar push forward, having to face many obstacles. Monolith has heavily entrenched themselves within the city in their attempt to prevent anything and anyone from reaching the NPP. Scar faces many obstacles, such as clearing out machine gun emplacements cutting power to electrical fences blocking the way out of Limansk. Once he has made it past, the only thing that's left is the underground part of an abandoned hospital. Another advance team is pinned down by Monolith, who are swarming in large numbers. Scar and Clear Sky forces work together to make a push through the hospital so they can get to the NPP. There is harsh resistance, but Scar pulls through. But during the process, an Mi-17 (Mi-8MT) helicopter controlled by the Military appears, opening fire on everyone in the Hospital, including Scar, and preventing progress. Scar eventually defeats the helicopter alone while the advance team catches up. After clearing passage to a network of tunnels, the advance team stays behind, giving Scar a window to reach the NPP.

The final battle is at hand. Strelok is within the vicinity, attempting to break through Monolith, Clear Sky and surprisingly Duty, who have somehow reached the centre and are taking up arms against Monolith. Lebedev thanks Scar for helping them reach the center and now needs his help to settle the score once and for all. Given a prototype Electromagnetic Pulse (EMP) Gauss Rifle, Scar must use it to disrupt the psi-blocker device on Strelok. Without the aid of the device, Strelok will not last much longer from the psi emissions. The activity in the zone is also believed to stabilize after Strelok is defeated. Fighting his way through Monolith on the upper parts of the NPP, Scar uses the Gauss rifle to disrupt the device which he succeeds in doing. Strelok is defeated and readings are taken to see if the stabilizing is beginning. But to Lebedev's horror, an unexpected and massive emission occurs, reaching levels beyond the norm. Everyone within radius of the plant, Duty, Clear Sky or otherwise are hit and begin succumbing to the effects of the emission. During the outro, they can be seen shaking unnaturally, crowded in corridors where brief and blurry black and white images on screens flash violently in their faces. These signs indicate that those whose lives weren't taken from the blast end up with a worse fate. They would seem to be in the process of being brainwashed to become part of the Monolith forces, or, like Strelok, become unwitting agents of the C-Consciousness.

From there, the Shadow of Chernobyl version of the zone unfolds and the story continues as seen in Strelok's point of view.

[edit] Gameplay

This game combines elements of survival horror (ammo scavenging, frightening atmosphere with powerful monsters), first-person shooters ("twitch-based" aiming, with a first person perspective), and RPGs (inventory management, quests, character interaction, armors and defense stats).

The most significant gameplay addition since Shadow of Chernobyl is the faction wars system. Different factions will struggle for territory, attacking to gain territory and then defending to keep it, while others then try to retake it. The player will be able to join and help factions in their battles. The stronger a faction becomes, the better equipment the traders can provide and their soldiers can use. The player character is a mercenary, and may do missions for any faction, or remain completely neutral, without consequence. Each of the main factions provide services, most importantly access to a trader and an engineer.

While Scar is always aligned with Clear Sky, and his ultimate goal is to defeat Strelok, he can fight against or ally with the four other factions in the Zone (Loners, Duty, Freedom and Bandits). The Swamp-dwelling Renegade or the Military factions cannot be joined. Careful choice of faction alignment needs to be considered in some parts of the story, for it may be difficult to progress further if the Stalker the player is interacting with is hostile, has needed information or is essential to triggering the next stage.

Other gameplay advancements since the first game include a deepened weapon customization system with the ability to repair damaged gear. Anomalies are harder to notice and now contain the artifacts in the game, which require a detector to locate. NPCs are given the ability to use hand grenades, take cover dynamically and use "blind-fire" techniques. Light machine guns have been introduced. There are NPC guides in the zone that will provide fast-travel for a fee. Emissions occur on an infrequent basis, requiring the player to take cover in a building pointed out by the PDA. If not adequately concealed, the player can die.

[edit] Factions and Weapons

Factions:

Army: The Ukrainian Army which are keeping the Zone unreachable from the outsiders. They are mostly drafted soldiers with limited skills, but also have a special task force in their ranks. Clear Sky also showed us the military somewhat made relations with some of the loner stalker groups, making profit while stalkers make theirs. The Army power in the Zone is very limited, along with their equipment, because of the economic reasons and having most of their forces fighting at the barrier.

Clear Sky: A faction which has dedicated themselves to researching the Zone. They are lightly armed, low in manpower, and isolated in the swamps. Most of their manpower comes from wandering stalkers who are found in danger or in need of help by some of the main members of Clear Sky. These stalkers, appreciating the help of Clear Sky, join the faction, and some leave after paying their debt to the Clear Sky. Scar is always aligned with them throughout the story of Clear Sky.

Renegade: An elite bandit group which wasn't introduced in the Shadow of Chernobyl. They raided the Zone from the North-West and captured Limansk, isolating themselves within the area. They also try to control the Swamps, which makes them to wage war against Clear Sky eventually. They cannot be joined.

Loners: Rookie or free stalkers, who are not interested in other factions' goals and seek for treasure. Almost all of the other major factions get their manpower from this group, which is the largest in the zone. Those who have trained and suffered enough of Zone's dangers may be accepted by other factions. When this faction was introduced in Shadows of Chernobyl, it showed that there were stalkers who had no affiliations to other groups. Usually the most you will find are rookie camps, or small groups, but some like Bes's group in the Cordon, are looking for greater treasure by cooperating with the Army. They are regarded as the golden neutral faction of the zone.

Bandits: A large unorganized group of robbers and murderers. They capture and rob wandering stalkers and they are always hostile to almost all of the other factions. Any stalker who kills another stalker, or robs him of his belongings can be called a Bandit. They are one of the largest groups of stalkers in the Zone, trying to control the southward areas.

Duty: A group of dedicated soldiers and soldier wannabes which are under command structure of a military hierarchy. Being the most organized and fundamental group in the Zone, they are trying to prevent the Zone from spreading, and waging a "crusader" like war against mutants and other factions that have bad intentions. They also train, accomplish day and night watch duties, patrol their territory, and they also do research about the Zone, mainly about how to end it. They are allied with the scientists, and are rumored to be neutral towards the Army (but Army are hostile towards the Duty). They continuously clash with Freedom.

Freedom: Originally, the founder of this faction and the founder of the Duty's faction were friends, but later their vision for the future of the Zone greatly differed from each other, leading them and their followers to wage war against each other. While Duty restricts the Zone from the outsiders, Freedom aims for the opposite; basically Freedom wishes the outer world to be allowed freely into the Zone, also using the artifacts as they wish. They also believe in studying the zone. Freedom isn't very organized; they only have a sort of duty distribution which enables everyone to do what they are good at.

Mercenaries: An elite armed forces hired by an unknown customer, rumoured to be the grunts of the other Western European countries, which are trying to understand the happenings in the Zone. Others say this fraction is a secret Russian army group, disguised in a Western-based equipment, and trying to stop the independent research and military development. In any case, Clear Sky doesn't give enough data for us to make a certain claim, apart from being hired guns to do dirty work. The Mercenaries are far less powerful in manpower when compared to their state in Shadow of Chernobyl and can be eliminated with a single mission easily.

Monolith: A mysterious and unknown faction of Stalkers. From PDA records and logs, their intent would be to protect the NPP and the Wish Granter, which they revere. No one knows who they are aligned with, their mood or other intentions they have. They simply ward off those who stray too close to the Centre, shooting everyone on sight and never asking questions. There is no contact with them on a personal level, which leaves much speculation to be solved about them. They may be agents of the C-Consciousness. It is not quite clear how they recruit, except for perhaps the end of Clear Sky with the seemingly brainwashing of Stalkers.

Military Stalkers: Another secret organization which hires stalkers to accompany with the officials, for stopping the stalker activity. They cannot be found around by traveling; they only made a brief appearance in Shadow of Chernobyl's final scenes. They are heavily armed, mostly using silenced marksman rifles and are sent to some critical areas by the command of the Army.

Weapons:

Pistols: Makarov Silenced Makarov, Fort 12, Walther P99, Beretta M9, Browning HPSA, SIG 220, USP Compact, Desert Eagle .45, Colt 1911 .45

Shotguns: BM16 Sawn off, TOZ 34 Hunting Rifle, Winchester 1300, SPAS 12

SMG: MP5

Assault Rifles: AKS 74u, AKS 74, AN 94 Abakan, L85-A1, LR 300, SIG 550, HK G36

Snipers: AS VAL, VSS Vintorez (Special Forces version of the AS VAL), SVD, SVU

LMG: PKM

Explosives: VOG-25 Grenade Launcher, M203 Grenade Launcher, RG-6 / 6G30 40mm Grenade Launcher, RPG-7, RGD 5 Defensive Grenade, F1 Frag Grenade

Other: Knife, Explosive Barrels

In addition to the variety of the weapons themselves, there are many customization options ranging from scopes, silencers, and under-barrel grenade launchers, which are reflected upon the weapon's model itself, there are other modifications available that allow for tweaking the weapon's attributes, such as new slides and other non-visually represented modifications.

The weapons also degrade as they're used, much like in Shadow of Chernobyl. This causes jamming and decreased performance. Luckily, unlike in SoC, the player can find NPCs in most major encampments that will repair and even upgrade weapons and armor for a price.

Finally, additional ammunition types are a normal occurrence between the weapons. A prime example would be the use of Buckshot shells, Dart shells, and Slug shells for a shotgun. Other types of ammo usually include a standard version and an armor piercing version.

[edit] X-Ray 1.5 Engine

Advancements made in 1.5 include volumetric light, dynamic volumetric smoke, full volumetric fire, soft water, dynamic wet surfaces (with water streaming down the sides of surfaces), depth-of-field blur, DirectX 10 support, SSAO (Screen Space Ambient Occlusion). A complete day and night system is included along with improved weather effects.

However, the game will maintain the same minimum system requirements as Shadow of Chernobyl, and is scalable enough to run on outdated DirectX 8 hardware. The engine's revamp has allowed for improved and increased performance on most systems. Version 1.5.03 of the game supports MSAA for DirectX 10, while version 1.5.06 added support for DirectX 10.1.

[edit] Reception

Reception for Clear Sky has been generally positive. PC Zone UK and Games Master UK have both given Clear Sky a score of 88 out of 100, while Edge Magazine gave 7/10 saying the game "turns the best and worst of PC gaming into something extraordinary". ^[4] GamesTM gave the game 90/100 saying "Clear Sky chiefly succeeds because it transforms grim fantasy into a startlingly real-world experience". ^[4] PCGamer UK however, awarded the game 68% saying it is "The disappointment of the year", particularly criticizing the increased difficulty and that the atmosphere of the zone was not as well delivered as the original.^[5]

X-play's review was generally unfavorable at 60%, citing boring environments, glitches, and antiquated gameplay. GameSpot gave it 7.0/10 due the glitches, and hoping the patches will fix some major things. In GameSpot's "Best of 2008" the game was nominated in just one category, in "Best atmosphere" but it lost to Dead Space.

[edit] Bug Reports

This article contains weasel words, vague phrasing that often accompanies biased or unverifiable information. Such statements should be clarified or removed. (March 2009)

Clear Sky was released upon the 22nd August 2008 in Russia, with a patch being available at release (Patch version 1.5.03 for the International version, said to be identical to the Russian version 1.01 patch). It was soon after reported, on the GSC-gaming official forum among other places, that both the unpatched and patched Russian version suffered from severe stability issues. These included Crashes to Desktop (CtD), Blue Screens of Death (BSOD), bugs that made the game unplayable and a general poor performance of the game even on high end systems. These reports were not unanimous however, and several other members of the boards reported that they had few or no issues with stability, even if bugs in-game remained prevalent. Though these were suspect, given the change logs from GSC that have accompanied subsequent patches identify many script errors being fixed. These script errors always result in a CtD, which the forums were consistently reporting.

On September 5 2008 the game was officially released in the rest of the world, except in North America and on various online distributors. Reports of poor performance are still prevalent around the official forum and some of the fansites. Since then the game has been patched several times and the latest is now currently 1.5.09, fixing most of the gamebreaking bugs that were present upon release. However some players are continuing to report severe bugs with the game, including severe graphical issues that were not present in 1.5.04. One of the new now potentially game-breaking gameplay bugs is the crash to desktop that happens when attempting to talk to wounded characters. CtD scenarios still abound in Clear Sky, some forcing players to restart their entire game or avoid a specific scenario or area.

Some players reported problems with game's StarForce and Tagès copy protection that prevented game from starting even when the original DVD was inserted.^[6]

[edit] Limited Editions

Separate limited edition versions of the game were released in conjunction with the standard version.

The Russian limited edition is presented in a larger box and contains the game disc, a bonus disc, two kerchiefs, an A2-sized map of the Zone, several patches with logos of the game's factions, a dog tag, a custom lighter and a little white ball called "The Clear Sky Artifact".

The second limited edition, released in the rest of the world, is presented in a metal box and also contains a bonus disc filled with extras (such as bonus artwork, screen savers, making of videos, a five-part interview with Oleg Yavorsky the PR Director for GSC Game World and the soundtrack) and the A2-sized map of the Zone.

Polish limited edition, presented in medkit-like bag with game's logo contains game disc, soundtrack, patch with logo of one the game's factions, stickers with logos, small map of the Zone, t-shirt with game's logo on chest and inscription "Сделано в Чернобыле" ("Made in Chernobyl") on back.

[edit] Digital Rights Management

Stalker: Clear Sky uses the digital rights management (DRM) software Tagès as copy prevention. Some versions can only be installed on a limited number of machines (5)^{[7] [8]}.

Many people are also experiencing issues registering the game at all. Tagés offers two ways of registering the product, an Automatic Mode, which automatically communicates with the Verification Server, and a Manual Mode, where one can access a code via a web browser.
