Every once in a while, a game publisher will wise up and offer a low-cost or even free treat to the game-playing public. Sometimes they are seriously behind the times and release games that are over a decade old for free. Some others throw some newer cookies out, and THQ and Valve are doing just that with a weekend sale for S.T.A.L.K.E.R.
This Steam-only offer has the original S.T.A.L.K.E.R.: Shadow of Chernobyl game selling for a mere $5, a fourth of the regular current price.
Considering the game is not yet even two years old, it's certainly a good deal if you're a FPS fan. A full-fledged, modern game for only $5? Almost too good to be true.
