S.T.A.L.K.E.R. Shadow of Chernobyl

On April 26, 1986, the world's worst nuclear accident occurred: Reactor
4 of the Chernobyl power station exploded, releasing clouds of
radioactive matter. Soviet authorities established a 30km 'Exclusion
Zone' around this nuclear wasteland, but in 2006 a second explosion
rocked the stricken reactor, obliterating all living things and causing
the Zone's boundaries to ripple outwards. From this epicentre came
waves of mutated creatures, deadly radiation and strange, anomalous
energy. The Zone was cordoned off by the military who would shoot on
sight anyone foolish enough to brave the horrors within. It is
now 2012 - man has ventured further and further into the heart of the
Zone driven by reports of strange 'artifacts' imbued with anomalous
energy. Mercenaries and bounty hunters compete to recover these
artifacts, which command extortionate prices on the black market.
Others seek to find the truth behind the Zone, whilst some merely revel
in the desolate lawlessness of the place. Whatever their motivation,
over time these individuals - Scavengers, Trespassers, Adventurers,
Loners, Killer, Explorers and Robbers - have become known as
S.T.A.L.K.E.R.s.Awakening in the Zone, you are one such
S.T.A.L.K.E.R., fighting for survival in this man-made Hell, whilst
trying to discover the truth behind Chernobyl's sinister past and
ominous future.
