S.T.A.L.K.E.R.: Clear Sky ~ Third view

The player assumes the role of veteran Stalker Scar, who is injured and rendered unconscious by an energy emission while guiding a group of scientists through the Zone. Scar, the only one to survive, is then rescued by Clear Sky, a secret independent Zone faction dedicated to researching and learning about the Zone in their attempt to better understand it and its related phenomena. It is not known how Scar has survived the emission, but it is noted he has suffered damage to his central nervous system and seems to exhibit other, subtle physiological changes.
