Smissmas, the magical time of year when men with big guns, questionable morality, and an unusual commitment to a two-tone color scheme are given all-new, all-festive ways to inflict violence upon one another, has once again come to Team Fortress 2!. This year's magical event features a slew of new Festivizer weapons, 17 winter-themed community cosmetics, and—just in time for the holiday season—three new taunts. 

Apart from the new stuff, the holiday update will also make some improvements to Casual matches and autobalancing. At the end of Casual matches, players will now automatically be formed up into a new match with the same players and teams, and will be given the opportunity to vote on which map is played. A new autobalancing system will encourage players to switch sides when necessary by offering bonus XP to volunteer turncoats. 

And of course there will be stuff to buy in the Mann Co. Store, much of it on sale. It doesn't look to be the biggest Smissmas update of all time, but then again, as Valve says, giving people gifts can bite you in the ass. Maybe you should just be thankful for what you get. Speaking of which, you can get the details at teamfortress.com.
