Not to be outdone by the bevy of sales from Microsoft, the PlayStation Network has announced their "11 for 11" sale. That's right, eleven PS3 games for half the price, in honor of 2011.  (Personally, I can't wait for 2099. That sale should be incredible.)  There is a smattering of co-op goodies sprinkled into the lineup, including Deathspank: Thongs of Virtue, Hoard, Soldner-X2: Final Prototype, Comet Crash, and Shatter.  These offers are only available until the end of the month.  For a full list of pricing and games getting the half off treatment, read on.
