S.T.A.L.K.E.R.: Shadow of Chernobyl (DVD)

On the afternoon of April 12 in 2006, a massive explosion shattered the
Chernobyl area. The Zone, as the area got to be known, was characterized
by anomalous energy disturbances, rendering even the most advanced form
of protective suits worthless to would be rescue teams. Months passed
and nothing could be done. The military quarantined the area to prevent
unauthorized entry and perhaps even reassure the local populace that the
area was under control and confinement. Almost 4 years after the initial
event, expeditions can now safely traverse several kilometers deep into
the Zone. Among these are the Stalkers, poachers that enter the zone
searching for artifacts and anomalous formations that are highly sought
after by certain organizations and groups.

The player controls a Stalker, venturing into the Zone in order to
acquire information, technology and artifacts to sell and possibly put a
mysterious puzzle together. Avoiding the dangers within and the military
because as a Stalker you are effectively a thief, and the army that has
quarantined the area, don't take kindly to trespassers. Within the Zone
you will have to detect and avoid the bizarre phenomenon's (anomalies)
that plague the area, avoid or eliminate various kinds of mutants and
you can even expect competition from other Stalkers.
