Heads up FPS fans. S.T.A.L.K.E.R. Shadow of Chernobyl is on sale this weekend on Valve’s Steam store for a fiver. That’s quite the discount off the already quite reasonable price of $20.

While S:SoC never reached the heights of popularity of Half-Life, it was quite the interesting game in itself. Released in 2007, it combines a fairly straight forward FPS with some interesting survival horror elements. And hey, for $5.00, why the heck not?
