According to UkraNews, GSC Gameworld, the creators of the S.T.A.L.K.E.R. series, are closing down, as per the decision of GSC Gameworld CEO Sergei Grigorovich. This quite probably means this will be the end of the S.T.A.L.K.E.R. series. This information coincides with an apparent leak of high quality concept art and screenshots from S.T.A.L.K.E.R. 2 into the web. NMA, as usual, prepared a gallery for your viewing.
