Steam is celebrating this "lovely" holiday the best way it knows how, by discounting games. But not just any set of games are discounted, the focus here are cooperative games - you know ones you can play with your partner...or partners. Perhaps it's going to be a REALLY adventurous Valentine's Day.

The folks at Trendy Entertainment are out to celebrate the heart shaped holiday with special content for Dungeon Defenders.  A brand new challenge map called "Sky o Love" is now available as well as bonuses for pairing up boy and girl characters from the game.  In addition the tavern now has a love is in the air theme and there's four new outfits for your characters - including pants for the Squire.  For shame, I was told pants were optional.  

Amazon is having a huge PC download sale today to celebrate Valentine's Day and what better way to do that than to offer plenty of awesome co-op titles for super cheap!  Highlights of the deals include Borderlands: GOTY edition for $6.99, Dungeon Defenders for $2.99 and the Magicka Collection for $4.99.
