I'll give you anything! Just return my rifle, I beg you. I lost it by that place where those damn bloodsuckers live. Here are the coordinates. Be careful though. Bloodsuckers aren't the friendly kind. - Hunter
A short bio, that was being omitted from final version of S.T.A.L.K.E.R.: Shadow of Chernobyl game describes him as follows: 
Good-natured, cheerful guy whose only problem is that he can't shoot from anything other than a hunting rifle. Hunter hasn't even tried any other guns lately. He recently got into a scrap in the Wild Territory and lost his family rifle. Now he is lounging about in the bar hoping that someone will give him his rifle back.
