If you've somehow avoided accumulating a backlog over the year or just enjoy the act of spending money, Steam and Amazon have some weekend gaming deals to help you burn cash.

Steam enthusiasts can splurge on the service's 2K Games Weekend, which includes Bioshock Infinite for $13.59 and Civilization 5, Spec Ops: The Line and Borderlands 2 for $14.99 apiece. PixelJunk Monsters Ultimate is $9.99, or if you say to hell with the past decade, 1998's Baldur's Gate: Enhanced Edition is an even $5.

Amazon has blacked out $30 from The Bureau: XCOM Declassified's price on Xbox 360 and PS3 while knocking the PC version down to $19.99. Splinter Cell: Blacklist has crept its way to $39.99 for the Xbox 360, PS3, PC and Wii U, but you can gear up for a special mission with its Aircraft Edition for $99.99 on the PS3, Xbox 360 and PC.

If you'd rather get ready for the PlayStation 4, Amazon is also offering $30 of bonus credit towards a DualShock 4 if you trade in $30 worth of qualifying video games. You can check to see if anything you're willing to part with is eligible through the search function on the promotion's page.
