GSC Game World’s latest story trailer for STALKER 2: Cost of Hope spotlights two pivotal characters, series veteran Zulu and the mysterious Mavka, as the Duty vs Freedom war reignites across two massive new regions.
GSC Game World released a new story and character trailer for S.T.A.L.K.E.R. 2: Cost of Hope on June 12, 2026, giving players a detailed look at the two figures who will drive the expansion’s narrative: the returning Duty veteran Zulu and the enigmatic Freedom-affiliated Mavka. Cost of Hope is the first major story expansion for Heart of Chornobyl and is set to launch simultaneously on PC, Xbox Series X|S, and PlayStation 5 in summer 2026.
Who Are Zulu and Mavka?
Zulu is a familiar name for long-time STALKER fans. He first appeared in S.T.A.L.K.E.R.: Call of Pripyat (2009) as a former Duty member who had broken away from the faction after a skirmish between Duty and Freedom at Yanov station. In Cost of Hope, mysterious events have brought him back into Duty’s ranks at the personal request of General Voronin. According to GSC’s official character profile, Zulu remains fiercely devoted to Duty’s core mission: protecting humanity from the Zone’s threats.
Mavka is a brand-new character. She serves as the commentator of the Arena in Rostok, Freedom’s stronghold, delivering sharp-tongued praise and criticism to combatants while mutants tear them apart. But GSC has made clear that the Arena is far from why she entered the Zone in the first place. Mavka increasingly slips away on solo expeditions, hinting at hidden motivations that the DLC will explore in depth. Her connection to Freedom and her apparent rivalry with Zulu position her as a central figure in the expansion’s branching storyline.
Why Is the Duty vs Freedom War Erupting Again?
The conflict hinges on the collapse of the D4 Treaty, a pact signed by all Zone factions before the events of Heart of Chornobyl. Under this treaty, Duty withdrew from Rostok to the Cement Factory while Freedom took control of the district and established a thriving economy based on a new currency called coupons. The arrangement held for a time, but the trailer makes the breakdown explicit: Voronin declares, “That’s the end of D4.”
Freedom’s leader Miklukha accuses Duty of attacking Freedom members in violation of the treaty, while Duty insists the treaty was already being undermined. Players step into this escalating war as protagonist Skif, forced to pick sides in what GSC describes as “a tangled web of intrigue and half-truths, where no choice is clean or truly right.” Leaks and trailer analysis suggest a mysterious Psi-embryo may be the prize both factions are fighting over.
Two New Regions: CNPP and Iron Forest
Cost of Hope opens up two major regions that were locked off in the base game. The Chornobyl Nuclear Power Plant (CNPP) is the most anticipated location in the franchise’s history. Forbidden for decades, the reactor complex now calls stalkers back. The trailer shows Skif rappelling into what appears to be the destroyed remains of Reactor 4, battling poltergeists inside its corridors.
The second region, Iron Forest, features labyrinthine paths and previously unseen locations. GSC confirmed on Xbox Wire that each region functions as a full-sized territory with its own hub, dozens of smaller sub-locations, quests, and activities. These are not compact side areas but substantial additions to the Zone’s map.
Beyond the two new zones, the trailer also reveals returns to previously visited locations in updated states. The destroyed SIRCAA institute confirms that some DLC events take place after the Heart of Chornobyl campaign’s Signal finale, and areas like Lymansk, Laboratory X-16, and the Jupiter Underground appear in trailer frames.
Dozens of Hours of Gameplay and New Gear
GSC Game World has described Cost of Hope as a non-linear expansion that will take dozens of hours to complete. Players who want to see everything can expect considerably more time on top of that figure. The studio’s Xbox Wire post specifically states: “More engaging quests, more memorable characters and their stories, and more answers to the questions raised both in Heart of Chornobyl and the original games.”
New equipment confirmed through trailers and official sources includes a modified variant of the HK G3 assault rifle (dubbed the “Fallschirmjäger” or Paratrooper version, seen in Mavka’s artwork), an SKS rifle, a new submachine gun, and Zulu’s unique machine gun. The Svarog detector replaces the Veles with a blue-tinted radar display. New mutants include reworked versions of Kadaver with devices attached to their heads, and the central Psi-embryo creature housed in Laboratory X-16.
How Does the DLC Integrate with the Main Campaign?
Unlike traditional standalone expansions, Cost of Hope runs parallel to the Heart of Chornobyl campaign. After installing the DLC, players receive a signal on Skif’s PDA during the main storyline, which triggers the expansion’s narrative thread. There is no need to finish the base game first. This design means the DLC events interweave with the core story, reinforcing the living-world feel that the A-Life simulation system supports.
Player decisions carry significant weight. The non-linear story principle from the main game applies here as well, and GSC has stated that a single playthrough will not reveal the full scope of the narrative. Choices affect not only outcomes but the general direction of the story itself, encouraging multiple runs.
The Middle Chapter of a Second Trilogy
GSC Game World has positioned the STALKER 2 saga as a “second trilogy”, mirroring the structure of the original three games. Heart of Chornobyl is chapter one, Cost of Hope is the middle chapter, and a still-unannounced second story DLC will serve as the conclusion. The studio has been transparent about this long-form plan, noting on Xbox Wire: “Together with the future second story DLC, it will form a new large story within the S.T.A.L.K.E.R. saga.”
The ambition tracks with the game’s commercial performance. STALKER 2: Heart of Chornobyl sold one million copies within its first 48 hours in November 2024 and reached over six million players by March 2025. Steam revenue estimates place total copies sold at approximately 6.7 million as of May 2026. The PS5 version launched on November 20, 2025, further expanding the player base. Cost of Hope arriving simultaneously on PS5 breaks the timed exclusivity pattern used for the base game.
Pricing, Editions, and Platform Details
No standalone price for Cost of Hope has been officially confirmed. The Ultimate Edition ($109.99) includes a Season Pass covering both planned story expansions, meaning owners get the DLC at no extra cost. Industry estimates suggest the DLC could be priced around $20 individually, but GSC has not commented on this. The expansion launches on the same day across PC (Steam, Epic Games Store, GOG), Xbox Series X|S, Xbox Cloud Gaming, and PS5. Both the base game and the DLC support Xbox Play Anywhere, allowing a single purchase to work across Xbox console and PC.
What Players Are Asking
Do I need to finish Heart of Chornobyl before playing Cost of Hope?
No. The DLC triggers mid-campaign through a PDA signal and runs in parallel with the main story. You can start it during a playthrough without completing the base game first.
Is Skif still the protagonist?
Yes. GSC confirmed Skif remains the playable character. Zulu and Mavka are key NPCs who drive the story forward alongside faction leaders Voronin and Miklukha.
Can I choose between Duty and Freedom?
Yes. The non-linear structure allows players to pick sides. Trailer breakdowns and leaks suggest there may even be choices within factions, such as supporting Zulu or Voronin within Duty’s own ranks.
Is there an exact release date yet?
GSC has only confirmed “Summer 2026.” No specific date has been announced, but the recent surge of official trailers and lore posts suggests the launch window is approaching.
Will the DLC be on Game Pass?
While the base game was available on Xbox Game Pass at launch, GSC has not confirmed whether Cost of Hope will be included in the subscription. The Season Pass inside the Ultimate Edition is currently the confirmed access path beyond a standalone purchase.
