Alright, so here's my problem..
I finally got out of the level I was stuck on but now I seem to be stuck AGAIN.
Right after I get out of the underground tunnel and into the military place( The one where you have to steal documents), I seem to always die. I have no more bread, bandages, radiation reducers, or first aid kits to use. The radiation either kills me or the military guarding the place.

All the saves I have are either in the junkyard ( garbage) area or in the underground tunnel. The only option I seem to have left is to start from the beginning and stack up on stuff so I'm prepared....

There is a stalker thread already.

Oh, I apologize.. I didn't see it because I'm kind of pissed at the moment and didn't bother to search for another thread.

Well, you might just have to start over from the last save. S.T.A.L.K.E.R. can be rather cruel at times. Remember the golden rule; Save often, and save saves.
