Got a job for you, Marked One...
GSC Game World is a game developer, based in Kiev, Ukraine. The first game they developed was Codename: Outbreak, though after that they were better known for their Cossacks series, and then the S.T.A.L.K.E.R. series.
In November of 2007, GSC got Developer Rights to make Xbox 360 games, and in September of 2009, they announced a port of S.T.A.L.K.E.R. to come to consoles, though only after the release of Call of Pripyat due to low man-power at GSC.
In December 9, 2011, GSC was dissolved and subsequently, STALKER 2 was cancelled. Many employees, especially those who worked on the S.T.A.L.K.E.R. series, formed two new studios and made new games that were inspired by their past work.
In December 2014, 3 years after their closure, GSC reopened and announced a new game in development. As of December 2015 they are working on a 3D remake of their other main IP, Cossacks.
