Lost Path is a game mod for S.T.A.L.K.E.R.: Call of Pripyat. It provides a realistic Zone with constantly warring factions for supremacy and exclusivity. A separate tab is given in the PDA, which displays the strength of relationship groups, the number of captured bases, territories, and resources available. You can follow the development of a particular group, and also contribute by donating to any Mentor of your clan.
