The most significant gameplay addition since Shadow of Chernobyl is the faction wars system. Different factions will struggle for territory, attacking to gain territory and then defending to keep it, while others then try to retake it. The player will be able to join and help factions in their battles. The stronger a faction becomes, the better equipment the traders can provide and their soldiers can use. The player character is a mercenary, and may do missions for any faction, or remain completely neutral, without consequence. Each of the main factions provide services, most importantly access to a trader and an engineer.While Scar is always aligned with Clear Sky, and his ultimate goal is to defeat Strelok, he can fight against or ally with the four other factions in the Zone (Loners, Duty, Freedom and Bandits). The Swamp-dwelling Renegade or the Military factions cannot be joined. Careful choice of faction alignment needs to be considered in some parts of the story, for it may be difficult to progress further if the Stalker the player is interacting with is hostile, has needed information or is essential to triggering the next stage.
