The highly under-appreciated shooter S.T.A.L.K.E.R: Shadow of Chernobyl is on sale for the low price of $5 on Valve's Steam platform until Monday. Developed by Ukrainian-based GSC Game World, the 2007 shooter takes place in an alternate reality where a second nuclear disaster takes place in at the Chernobyl Nuclear Power Plant in Ukraine.

Normally priced at $19.99, Shadow of Chernobyl is a steal at $5; however, as solid as the FPS is, it also includes numerous video game storyline cliches like an amnesiac protagonist and flesh-hunting mutants. Where are all the games with flesh-hunting amnesiac mutants, right?
