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.
