If you're still holding out on
Call of Duty: Modern Warfare 3 (like I am) then you might have a little more incentive to pick it up. Steam is hosting a
free weekend for the game so you can try a free sample for a couple of days. The game is also 33% off during this period. MW3 is still a fairly new game so 33% off only means the game is $40 instead of $60, but that is a decent discount from the shelf price. Personally I've been burnt out on COD ever since Black Ops royally disappointed me, and I think it's bogus that Activision charges full retail price for the digital versions of the game, so I won't be partaking this time.
