GSC Game World's S.T.A.L.K.E.R. 2: Heart of Chornobyl has moved from a base game into a post-launch cycle built around one large expansion and a series of numbered updates. The studio announced Cost of Hope on July 27 as the first major story expansion, set for August 20, with two new regions, the Iron Forest and the Chornobyl Nuclear Power Plant, and a story about the conflict between the Duty and Freedom factions. A story trailer in June framed the expansion around that faction war and a non-linear narrative with over 20 hours of main story gameplay.
The expansion shipped on August 20 alongside Update 2.0, which moved the game to Unreal Engine 5.5.4 and overhauled lighting, AI, and difficulty settings. Cost of Hope added the Iron Forest and the power plant as playable areas, with protagonist Skif joined by Duty veteran Zulu and Freedom's Mavka. It is priced at 3,990 yen and is included in the Ultimate Edition; Deluxe Edition owners get it at no extra cost. Access requires more than 20 hours of main story progress and completion of the SIRCAA facility quest. The PC version holds a Metacritic score of 85 from 14 reviews.
After the expansion, GSC turned to the simulation systems. Update 2.1, called The Zone Lookout, arrived on October 28 for PC, Xbox Series X|S, and PlayStation 5, with A-Life display range settings, a Dynamic option that scales to hardware, rebalanced long-distance combat, and a paid guide feature that lets squad leaders lead the player to explored destinations. A 30% sale ran on Steam and the Microsoft Store. Sega published a Japanese accolade trailer for Cost of Hope on October 1, collecting recommended comments from Japanese game media.
