A series of strange emissions that passed through the Zone did not go unnoticed. The once unremarkable pioneer camp, which was off-limits due to the high radiation levels, suddenly came to life...

Those who have made it out alive have told many fascinating yet equally horrifying tales about that place.

A seasoned S.T.A.L.K.E.R., by the name of Yak, is tasked with an expedition and escorting a group to that very camp.

What dangers await them?
What hides in that fabled place?
This, you will have to find out yourself.
