Valve has released a new DLC which contains four new items for the Soldier class. Inspired by a steampunk aesthetic and designed by Weta, Dr. Grodbord's Victory Pack adds ray guns to the game, much to the chagrin of players who insist that Team Fortress 2 has an "art style" of some sort.
The items include the Cow Mangler 5000, The Righteous Bison, Pith Helmet and Goggles, and Novelty Pipe and Mutton Chops.
Further details can be found at the game's official website here.
