Steam's big deal this weekend is actually a weekend-long sale of 2K's
most popular (or in the case of Duke Nukem Forever, most infamous) titles. Today's showcase is the
Bioshock series, with both the first game and, in my opinion the vastly superior sequel, going for only five bucks a pop. If you don't have the Bioshocks you probably should pick them up, but take a look at the other 2K stuff as well--while the aforementioned Duke is in there stinking up his corner of the sale,
Darkness 2 and
Borderlands are on sale as well, along with some other good games you might've missed.
