In a company announcement by Ukrainian video game developer, GSC Game World, they have decided to shut down their studios, resulting in the cancellation of the post-apocalyptic shooter sequel S.T.A.L.K.E.R. 2. The reasons for the shut down is that no agreement was reached between the rights owners of S.T.A.L.K.E.R. and the new investors, as you can see from their post on their official facebook page. More posts by the facebook page administrators and GSC Game World employees, Joe Mullin and Oleg Yavorsky, show that the S.T.A.L.K.E.R. team was working on the sequel without pay as they were trying to find new investors, which turned out to be a disappointment.
Problems were first revealed back in December of 2011, as the CEO of the studio, Sergei Grigorovich, reported that he decided to shut down the studio, although, work still continued...
