by Allison Dec 17,2025

S.T.A.L.K.E.R. 2: Heart of Chornobyl has unveiled its development roadmap for late 2024, detailing enhancements to both the core game and Zone Kit Modding Tools alongside planned PlayStation 5 and PS5 Pro versions.

"Our primary focus is transitioning to Unreal Engine 5.5.4," stated GSC Game World in their announcement. "While this brings improved visuals and tools, the critical upgrade lies in the engine's optimizations - delivering smoother performance and greater stability throughout the Zone."

The studio acknowledges this major technical overhaul might "impact other update timelines," but affirms: "We're embracing this challenge like true stalkers, fully committed to achieving our 2025 objectives."

While multiplayer features remain conspicuously absent from the roadmap (despite fan expectations), here's the planned development timeline:
