S.T.A.L.K.E.R. 2: Heart of Chornobyl vs Castle of Heart: Retold

• Perspective: First-Person
• Multiplayer: Free Multiplayer Update planned post-launch (Details TBD)
• Setting: Chornobyl Exclusion Zone, Ukraine (Near Future, Post-Second Disaster)
• Platforms: PC (Windows), Xbox Series X|S (Day one on Game Pass)
• Unique Feature: Seamless Open World Chornobyl Zone, A-Life 2.0 System, Non-Linear Story with Meaningful Choices, Intense Survival Mechanics, Anomaly & Artifact Hunting, Mod Support (Confirmed).

• Perspective: 2.5D Side-Scroller
• Multiplayer: Single-Player Only
• Setting: Slavic Mythology
• Platforms: PC, PS5, Xbox Series X|S, Nintendo Switch, Nintendo Switch 2 (TBA)
• Unique Feature: A unique curse mechanic that acts as a timer, where the player's health constantly depletes and must be replenished through aggressive combat, creating a timed-runner feel.

• None Expected (Persistent AI Companions): The S.T.A.L.K.E.R. series traditionally emphasizes a lone wolf experience for the player character. While temporary AI allies for specific missions or dynamic A-Life 2.0 squad interactions are likely, persistent, commandable companions are not a typical feature of the core gameplay.
• Temporary Quest-Specific Allies / Faction Squad Mates (A-Life 2.0): During certain quests or as part of the A-Life 2.0 system, Skif might temporarily team up with other AI-controlled stalkers from friendly or neutral factions. They would provide combat support based on their faction's typical equipment and behavior. Their survival would likely not be critical to mission success beyond specific scripted events.
  Human (Stalkers from various factions)

• Artifacts: Found within or near dangerous anomaly fields. Require special detectors to locate and often careful maneuvering to retrieve. Provide powerful passive buffs (e.g., health regeneration, bullet resistance, increased carry weight, anomaly protection) but may also have negative side effects (e.g., emit radiation, reduce stamina). Can be equipped in artifact containers on a belt/suit.
• PDAs (Personal Digital Assistants): Looted from fallen stalkers or found in hidden stashes. Contain text logs, audio diaries, mission data, coordinates for stashes, or information about other stalkers and Zone events. Key for lore and finding hidden supplies.
• Documents & Research Notes: Found in abandoned laboratories, military outposts, or hidden locations. Provide backstory on the Zone's origins, scientific experiments, faction ideologies, and mutant behavior.
• Unique Weapons & Armor (Stash Items): Rare, often named, versions of standard gear with improved stats, unique properties, or pre-installed modifications. Found in well-hidden stashes, as quest rewards, or looted from powerful enemies.
• Zone Folklore Items / Mementos (Speculative): Could include items like old photographs, trinkets, or handcrafted objects that offer small glimpses into the lives of those who lived in or ventured into the Zone before or after the disasters. (Purely speculative, but fits the S.T.A.L.K.E.R. atmosphere)
• Guitar & Harmonica Songs (Playable by NPCs): Not a traditional collectible for the player, but finding NPCs who play unique songs around campfires is a memorable atmospheric element of the series. Players might collect song 'data' or similar.

• Crystals of Mokosh: Four hidden gems are scattered throughout each of the game's 20 levels. Collecting them extends Svaran's maximum health.
• Stone Hearts: Floating pickups found throughout levels and dropped by enemies. These are essential for replenishing Svaran's constantly draining life bar.

• Pistols (e.g., Makarov PM, Fort-12, Walther P99, Desert Eagle): Sidearm
  Common sidearms for backup or when primary ammo is scarce. Expected to include classic S.T.A.L.K.E.R. pistols and new additions. Customizable with suppressors, sights, etc. (Speculative details based on franchise)
• Submachine Guns (e.g., MP5, PPSh-41, AS Val - integrated suppressor): Automatic (Close to Medium Range)
  High rate-of-fire weapons for close encounters. AS Val variant would be specialized for stealth. (Speculative details based on franchise)
• Assault Rifles (e.g., AKM-74/2, AN-94 Abakan, L85, G36, FN F2000): Automatic/Semi-Auto (Versatile)
  Workhorse weapons of the Zone. Expected variety of Eastern Bloc and Western rifles, highly customizable with scopes, grenade launchers, silencers, and magazines. (Some confirmed from gameplay, others speculative)
• Shotguns (e.g., TOZ-34, SPSA14, Protecta, Chaser 13): Close Quarters (High Damage)
  Devastating at close range against mutants and unarmored humans. Pump-action, semi-auto, and automatic variants expected. Can use buckshot or slugs. (Speculative details based on franchise)
• Sniper Rifles (e.g., SVD, SVU, VSS Vintorez, Gauss Rifle): Long Range (Precision/High Power)
  For taking out targets from extreme distances. VSS Vintorez for silenced sniping. The Gauss Rifle is an iconic, powerful experimental weapon. (Some confirmed from gameplay, others speculative)
• Machine Guns (e.g., RPK, PKM): Automatic (Suppressive Fire)
  Heavy weapons with large magazines for sustained fire, useful against groups or heavily mutated creatures. (Speculative based on franchise)
• Launchers (e.g., RPG-7, Bulldog 6): Explosive (Anti-Personnel/Anti-Structure)
  Rocket launchers and grenade launchers for dealing with heavily armored targets or groups. (Speculative based on franchise)
• Melee Weapons (Knives, Crowbars, Shovels - expected): Close Quarters (Silent/Last Resort)
  Basic melee options for stealth kills, breaking crates, or desperate situations. (Speculative details based on franchise)
• Throwables (Bolts, Grenades - F1, RGD-5, Smoke): Tactical/Utility/Explosive
  Bolts are essential for detecting anomalies. Grenades for combat. Smoke grenades for cover or distraction. (Bolts confirmed, grenades highly expected)
• Unique & Modified Weapons (Expected): Special Variants
  Stalkers often modify their weapons. Expect to find unique, named versions of standard firearms with special properties, better stats, or unique attachments, possibly tied to quests or rare loot. (Speculative based on franchise)

• Sword: Primary Melee
  Svaran's main weapon for close-quarters hack-and-slash combat.
• Secondary Melee Weapons: Torches, Hatchets
  A variety of melee weapons that can be picked up and used for a limited time. Svaran drops his secondary weapon if his first health bar is depleted.
• Secondary Ranged Weapons: Javelins, Crossbows
  Ranged weapon options that can be found in the levels for engaging enemies from a distance.

• Stalker Suits (e.g., Sunrise Suit, SEVA Suit, Exoskeleton, Trench Coats, Leather Jackets): Various outfits and protective suits worn by stalkers. These provide varying degrees of protection against ballistic damage, mutant attacks, radiation, anomalies (thermal, chemical, electrical, psychic), and environmental hazards. Suits often have slots for Artifact containers and may have integrated features like night vision or closed-cycle breathing systems. Heavier suits like Exoskeletons offer superior protection but reduce mobility and require battery power. Can be repaired and upgraded.
• Helmets & Gas Masks: Headgear providing ballistic protection and crucial for surviving in areas with toxic gas, high radiation, or specific anomalies. Gas masks require filter replacements. Different types offer varying levels of protection and durability.
• Artifact Containers: Specialized containers attached to belts or suits that allow stalkers to safely carry radioactive or otherwise hazardous Artifacts, mitigating their negative effects while benefiting from their positive properties. Upgradable for more slots or better protection.
• Backpacks: Increase carrying capacity for loot, supplies, and ammunition. Different sizes and types may be available.

• Knight's Armor: Svaran wears a suit of armor, but there is no traditional armor system with defensive stats. His durability is determined by his health bar, which is extended by collecting Crystals of Mokosh.

• Stalker Outfits (Trench Coats, Leather Jackets, Hoodies, Camouflage Gear): Players will likely be able to equip various pieces of clothing that make up a stalker's typical attire. While the primary protection comes from specialized Stalker Suits, underlying clothing might offer minor benefits or be primarily cosmetic. Expect a rugged, worn aesthetic.
• Faction-Specific Gear Appearance: Members of factions like Duty (strict military style, often red/black) or Freedom (anarchist, often green/camouflaged) typically have distinct visual styles for their armor and clothing. If Skif aligns with a faction, this might be reflected in available gear.
• Patches & Insignia (Speculative): A common element in stalker culture. Players might be able to customize their gear with faction patches or other insignia, though this is speculative for S.T.A.L.K.E.R. 2.
• Masks & Headgear (Balaclavas, Respirators, Tactical Helmets, Hoods): Beyond functional gas masks and helmets, various other head coverings are common for stalkers for anonymity or environmental protection, contributing to the overall look.

Progression is based on in-level pickups and collectibles. Players can find dozens of different melee and ranged secondary weapons throughout the levels. Collecting the four 'Crystals of Mokosh' hidden in each level will extend Svaran's maximum life bar. There is no traditional skill tree; progression is tied to player skill and health upgrades.

S.T.A.L.K.E.R. 2 will feature a seamless open world of approximately 64 sq km, one of the largest in gaming. It will encompass iconic locations from previous games (e.g., Pripyat, Chornobyl NPP, Red Forest, Cordon - TBD if all are present or reimagined) as well as new, unexplored territories within the Exclusion Zone. The world will be dynamic, with the A-Life 2.0 system simulating life for factions and mutants independently of the player. Expect diverse biomes from irradiated wastelands and dense forests to underground laboratories and abandoned urban areas.

The game is a linear 2.5D platformer. Players will travel across 20 levels set within four distinct, Slavic-inspired landscapes. Most levels have been completely rebuilt for the Retold version, featuring new animations and more detailed environments.

• No Player-Controlled Vehicles Traditionally
  The S.T.A.L.K.E.R. series has traditionally focused on on-foot exploration to emphasize the Zone's dangers and the vulnerability of the stalker. While military vehicles (APCs, helicopters) exist as environmental elements or enemy threats, direct player control of vehicles for general traversal has not been a core feature. This is expected to continue, though specific scripted sequences are always possible.
• Fast Travel (Guides - Speculative/Limited): NPC Service / Map Traversal Mechanic
  In previous games, experienced stalkers known as 'Guides' could offer paid fast travel services between major friendly encampments. A similar limited fast travel system might return, rather than unrestricted map-wide fast travel, to maintain immersion and the sense of journey.
• Traversal on Foot (Walking, Running, Sprinting, Crouching, Prone - expected): Player Locomotion
  Primary mode of movement. Skif will navigate the Zone on foot, managing stamina for sprinting, using stealth (crouching, possibly prone), and carefully navigating treacherous terrain and anomaly fields.

• Skif: Protagonist (Stalker)
  The new player-controlled protagonist. Details about Skif's background, motivations, and specific skills are largely unrevealed, but they are depicted as a capable lone stalker venturing deep into the Zone.
• Faction Leaders & Key Members (Duty, Freedom, Loners, Scientists, etc. - Speculative): Quest Givers / Allies / Antagonists
  Expect to encounter and interact with leaders and prominent members of the Zone's various factions. These characters will likely provide quests, trade opportunities, act as allies or enemies depending on player choices and faction alignment. Names and specific roles are TBD but will draw from established S.T.A.L.K.E.R. lore.
• Mysterious Zone Figures (e.g., Guides, Legendary Stalkers, Zone Cultists - Speculative): Lore Figures / Enigmatic NPCs
  The Zone is known for its mysterious and legendary figures. S.T.A.L.K.E.R. 2 will likely feature new or returning enigmatic characters who hold deep secrets about the Zone, its origins, and its future. These could include unique quest givers, hidden mentors, or dangerous ideologues.
• Scientists & Researchers (Speculative): Quest Givers / Information Source
  Mobile scientific labs and bunkers are a staple. Expect to interact with scientists studying the Zone, its anomalies, and artifacts, who will likely offer research-oriented quests and unique rewards or information.
• Traders & Technicians (Speculative): Merchants / Crafting & Repair NPCs
  Essential NPCs for buying/selling gear, ammunition, supplies, and for repairing and upgrading weapons and armor. Found in stalker camps and faction bases.

• Svaran: Playable Protagonist
  A noble Slavic warrior who is cursed and turned to stone. He must fight against time to defeat the evil sorcerer and save his beloved.
• Mira: Key NPC
  A priestess and Svaran's betrothed. Her tear brings Svaran back to life, and her rescue is his primary goal.
• The Sorcerer: Antagonist
  The main villain of the game. A servant of the evil god Chernobog who cursed Svaran and rules the land with dark magic.

• Main Story Questline (The Heart of Chornobyl)
  A non-linear series of core narrative missions following Skif's journey into the depths of the Chornobyl Exclusion Zone to uncover its greatest secrets, likely revolving around the mysterious 'Heart of Chornobyl.' This will involve navigating dangerous territories, interacting with various factions, making critical choices, and surviving encounters with deadly mutants and anomalies.
• Faction Quests (Duty, Freedom, Loners, Scientists, etc.)
  Optional storylines and tasks given by representatives of the Zone's major factions. Completing these will likely improve Skif's reputation with that faction, unlock unique rewards (gear, information, access to new areas), and potentially influence the balance of power within the Zone. Choices made may alienate other factions.
• Artifact Hunting Expeditions
  Venturing into dangerous anomaly fields to locate and retrieve valuable artifacts using specialized detectors and bolts. This involves careful navigation of invisible and lethal hazards, and often dealing with mutants attracted to anomalous energy.
• Stalker Contracts & Bounties (Speculative)
  Taking on jobs from traders, faction leaders, or other stalkers, such as eliminating specific mutant lairs, assassinating rival stalkers, retrieving lost items, or escorting individuals through dangerous areas. (Based on previous games & open-world tropes)
• Investigating Zone Mysteries & Legends
  Following clues from PDAs, documents, or rumors to investigate mysterious phenomena, legendary stalker tales, secret laboratories, or unexplained events within the Zone. These often lead to unique encounters or valuable discoveries.
• Clearing Mutant Lairs & Bandit Camps
  Systematically eliminating threats from specific locations to make areas safer for passage, secure resources, or fulfill faction objectives. Part of the dynamic A-Life 2.0 system might see these areas reclaimed by enemies over time if not patrolled.
• Survival & Resource Management Tasks
  Ongoing objectives driven by the game's survival mechanics: finding food and water, seeking shelter during emissions or hazardous weather, managing radiation exposure, maintaining weapon and armor durability, crafting ammunition and medical supplies, and finding safe places to rest.

A free multiplayer update is planned for release after the main game. Details are scarce, but it's expected to include PvP modes. Co-operative elements or a standalone mode like the once-planned S.T.A.L.K.E.R. Online (focused on raids) are speculative but possible.

Multiple editions have been announced: Standard, Deluxe (digital artbook, soundtrack, extra side quests, costumes/weapon skins), Ultimate (Deluxe content + Season Pass with future DLCs, more costumes/weapon skins), and physical Collector's Edition (Ultimate content + SteelBook, artbook, stalker figurine, letter, map, patches, keychain, etc.).

• Q: Is S.T.A.L.K.E.R. 2 a direct sequel to the previous games?
  A: Yes, S.T.A.L.K.E.R. 2: Heart of Chornobyl is a direct sequel, continuing the story and themes of the original trilogy (Shadow of Chernobyl, Clear Sky, Call of Pripyat). It features a new protagonist, Skif, but is set in the same universe and will likely reference past events and characters.
• Q: What is the A-Life 2.0 system?
  A: A-Life is a dynamic AI simulation system unique to the S.T.A.L.K.E.R. series. A-Life 2.0 promises an even more advanced version where NPCs, factions, and mutants live out their own lives, migrate, fight, and react to changes in the Zone independently of the player's direct presence, creating a truly living and unpredictable world.
• Q: Will S.T.A.L.K.E.R. 2 have a non-linear story?
  A: Yes, GSC Game World has emphasized that S.T.A.L.K.E.R. 2 will feature a branching, non-linear storyline with significant player choices that lead to multiple endings and impact the state of the Zone and its factions.
• Q: What are Anomalies and Artifacts?
  A: Anomalies are dangerous, physics-defying environmental hazards found throughout the Zone (e.g., gravitational distortions, pockets of intense heat or electricity). Artifacts are rare, valuable objects formed within anomalies that possess unique beneficial properties (e.g., health regeneration, radiation absorption) but often also have negative side effects. Stalkers hunt for artifacts to sell or use.
• Q: Will there be survival mechanics like hunger, thirst, and sleep?
  A: Yes, survival mechanics such as managing hunger, thirst, sleep, radiation exposure, bleeding, and equipment degradation are core staples of the S.T.A.L.K.E.R. experience and are confirmed to return in S.T.A.L.K.E.R. 2.
• Q: Is S.T.A.L.K.E.R. 2 using Unreal Engine 5?
  A: Yes, S.T.A.L.K.E.R. 2: Heart of Chornobyl is being developed on Unreal Engine 5, aiming to leverage its advanced features for graphics, world detail, and dynamic systems.
• Q: Will S.T.A.L.K.E.R. 2 support mods?
  A: Yes, official mod support has been confirmed by GSC Game World, which is a significant aspect of the S.T.A.L.K.E.R. community and franchise longevity.

• Q: What is Castle of Heart: Retold?
  A: It is a complete remake and definitive version of the 2018 Nintendo Switch exclusive action platformer, Castle of Heart. It features massively improved graphics, rebalanced combat, and a reimagined story.
• Q: What is the 'curse' mechanic?
  A: The protagonist, Svaran, is cursed to turn to stone. This translates into a unique gameplay mechanic where his health constantly drains like a timer. He must stay aggressive, killing enemies or finding pickups to replenish his health and survive.
• Q: Is it a hard game?
  A: Yes, it is designed to be a challenging 2.5D action platformer, similar in feel to classic games like Super Ghouls and Ghosts. Precision platforming and strategic combat are required.
• Q: What's new in the 'Retold' version?
  A: Almost everything has been enhanced. Most levels are rebuilt, graphics and lighting are overhauled, controls are more responsive, combat is rebalanced to be more tactical, and every line of dialogue and every cutscene has been remade.

Developed on Unreal Engine 5, S.T.A.L.K.E.R. 2 aims for cutting-edge photorealistic visuals. It will leverage UE5 features like Nanite (virtualized micropolygon geometry for extreme detail) and Lumen (fully dynamic global illumination and reflections). Expect highly detailed environments, realistic weather systems, advanced lighting, and detailed character/mutant models. Motion capture and photogrammetry are being used extensively.

Expected to feature an atmospheric and melancholic soundtrack, possibly by MoozE (composer for previous S.T.A.L.K.E.R. games) or similar artists, blending ambient electronic, industrial, and folk elements. Immersive sound design is a hallmark, with distinct anomaly sounds, mutant roars, weapon effects, and the oppressive ambience of the Zone (wind, Geiger counter clicks, distant gunfire).

Expected to be immersive and diegetic where possible, fitting the S.T.A.L.K.E.R. aesthetic. HUD will likely display health, stamina, radiation levels, ammo, equipped detectors, and time. PDA will be crucial for map, inventory, quests, and information. Dynamic indicators for hunger, thirst, sleep, and bleeding are staples of the series.

To Be Determined (TBD). Modern AAA games typically include a range of accessibility options, so it's likely S.T.A.L.K.E.R. 2 will offer features like customizable controls, subtitle options, UI scaling, and potentially gameplay modifiers, though specifics are unconfirmed.
