The events of S.T.A.L.K.E.R.: Call of Pripyat unfold shortly after
the end of S.T.A.L.K.E.R.: Shadow of Chernobyl following the ending in
which Strelok destroys the C-Consciousness. Having discovered the open
path to the Zone’s center, the government decides to stage a large-scale
operation to take control of the Chernobyl nuclear plant.
S.T.A.L.K.E.R.: Call of Pripyat utilizes the XRAY 1.6 Engine,
allowing advanced modern graphical features through the use of DirectX
11 to be fully integrated; one outstanding feature being the inclusion
of real-time GPU tessellation. Regions and maps feature photo realistic
scenes of the region it is made to represent. There is also extensive
support for older versions of DirectX, meaning that Call of Pripyat is
also compatible with older DirectX 8, 9, 10 and 10.1 graphics cards.
