Valve loves itself so much that it puts its own games into other studios' work on Steam -- we don't want to call it incestuous, but, well. It's kind of incestuous. Dungeon Defenders is the latest victim game to have a healthy Valve infusion, with pre-orders getting The Aperture Science Handheld Portal Device for the Huntress class and four Team Fortress 2 familiars, Heavy, Medic, Engineer and Pyro. Check out how these goodies work above and pre-order Dungeon Defenders on Steam, if you're into that sort of thing.
