Set before Shadow of Chornobyl, Clear Sky casts you as Scar, a mercenary drawn into conflict across the unstable Zone. Your route leads toward the Chornobyl Nuclear Power Plant through hostile factions, mutants, radiation, anomalies and deadly Emissions.
Explore locations including the Swamps, Limansk and the Red Forest, take on missions, and decide how to engage with rival factions. Faction Wars let you support groups competing for territory and influence the balance of power.
Survive encounters by managing your equipment and searching dangerous anomalies for artifacts with a detector. Find upgrade information, improve and repair weapons and armor, and build up your gear as you progress. The Enhanced Edition also includes visual updates and gamepad support.
The supplied reviews are sharply divided on the Enhanced Edition. Many criticize persistent bugs, crashes, and faction-war problems, while players who enjoy the game often single out the Zone’s atmosphere and locations, the faction conflict, and equipment upgrades. Some also appreciate the prequel story and the chance to explore the series’ world further.

Atmospheric visual enhancements including God Rays, Dynamic Screen Space Reflections, and Advanced Global Illumination effects.
Redesigned water shaders, upgraded skyboxes, and wetness effects.
