With holiday promotions in full swing, it'd probably be easier to tell you what isn't on sale this weekend. Most sites are swapping their best deals at least once a day, so you'll have to keep an eye on things if you want to snag a particularly handsome discount. As of writing, you'll find solid deals on FTL: Faster Than Light, LA Noire, Left 4 Dead 2, XCOM: Enemy Unknown, Sleeping Dogs, BioShock 1 & 2, Spec Ops: The Line, 2K strategy titles, Rayman: Origins, Torchlight II, Alan Wake, Red Orchestra 2, and both Witcher titles. Also, the Humble Indie Bundle 7 continues with three more games added this week.
