We know how boring most holly jolly holiday cards can be, so we were glad to see that a handful of Valve-ified greeting cards are now available for purchase at the game maker's online store. Featuring characters from Left 4 Dead, Left 4 Dead 2, and Team Fortress 2 in compromising holiday situations, there's no doubt that we'll actually – finally – send out greeting cards this year to everyone in our little black book. We're quite partial to the handful of TF2-themed images you see above (just look at The Spy, back with The Scout's mother!), but we're sure there's something for everyone in your list of Source Engine-loving holiday card receivers.
