S.T.A.L.K.E.R.: Clear Sky is a prequel set before Shadow of Chornobyl, following mercenary Scar as the Zone is shaken by a massive anomalous energy blowout. Scar’s investigation into the disaster is tied to Strelok’s fate and the events that shaped the Zone. Familiar places appear in their earlier state, while newly accessible territories give exploration a central role.
Survival is shaped by shifting faction power. Players can join a faction and fight rivals for territory, artifact fields and influence, or work for multiple factions as a mercenary. The game also pairs exploration with artifact hunting using detectors, as stalkers venture through dangerous areas and encounter new anomalies. Technicians can upgrade and customize weapons and armor, adding a practical layer to its action-RPG design.
Its single-player campaign is complemented by listed multiplayer options, including online PvP and LAN PvP.
