Saving us some cash this weekend, Steam is offering a 75% discount on GSC Game World's S.T.A.L.K.E.R. Bundle, which includes S.T.A.L.K.E.R.: Shadow of Chernobyl and S.T.A.L.K.E.R.: Call of Pripyat. The deal runs from now until 10AM PDT on Monday, August 23rd. So if you're looking for something new to play and are into "hardcore" shooters, you should definitely consider picking these up. ;)
