GSC Game World spent the summer of 2026 rolling out the first major story expansion for S.T.A.L.K.E.R. 2: Heart of Chornobyl. Cost of Hope was announced on July 27 and released on August 20, the same day the free Update 2.0 went live. The expansion adds two regions, the Iron Forest and the Chornobyl Nuclear Power Plant, each with its own hub, quests, and activities, and continues protagonist Skif's story on the same timeline as the main game. Update 2.0 migrates the game to Unreal Engine 5.5.4, overhauls lighting and AI, and adds customizable difficulty settings, three types of binoculars, and new weapons including the Arev assault rifle.
Coverage of the expansion centered on its faction narrative. Earlier trailers, including Between Duty and Freedom in June, framed the story around the conflict between Duty and Freedom, with choices that affect the Zone. The review noted a shift from the main game's lone-wolf survival toward faction-driven storytelling, following Skif alongside Duty veteran Zulu and Freedom's Mavka as they investigate the Blast. The PC version holds a Metacritic score of 85 based on 14 reviews.
The commercial picture expanded again in October, when Sega published an accolade trailer on YouTube collecting recommended comments from Japanese game media. The trailer points to a new agreement with GSC Game World that puts the Ukrainian studio's post-launch content into the same Japanese retail channel as the base game. Cost of Hope is available standalone or in the Ultimate Edition, and it is included at no extra cost for Deluxe Edition owners. The base game holds a CERO Z rating.
