If sci-fi action game Dark Sector slipped by you when it first hit stores, Steam's giving you another opportunity to buy. For the next week, you can buy it through the digital gaming platform for 33% less.

To put it in dollars, you can get it for $13.99 instead of $19.99. Dark Sector was first released for the PS3 and Xbox 360 in March 2008 and was finally brought to the PC two months ago. Players control Hayden Tenno, a secret government operative who contracts a mysterious disease that enables him to mutate. Good thing, too, because he's trapped in a nation that wants him dead.
