Kill the stalker called Sparrow is an optional side-mission featured in S.T.A.L.K.E.R.: Shadow of Chernobyl.
Description
Damn musketeers! Playing D'Artagnan, assholes! As if surfing around anomalies and bowing to bullets is not enough, the oafs have now taken to fighting duels! Get this: there was this row... no one can even remember any more what started it. So these two dumbheads decided to shed some blood. And there you go, one dropped dead... a fine stalker he was, too! And the other one, Sparrow, beetled off, because I'd be the first one to put a bullet in his head. Find him. I'm sure he's still in the Zone. Will you do it?
