Team Fortress 2 has gotten a new, community-created update. The "Robotic Boogaloo" is the first update entirely made by the community, and it features a plethora of new hats for your metal minions.
The official site gives the details. Robotic Boogaloo features 57 new items, with a particular focus on mechanical hats. Similar to the usual updates, it even features a comic and accompanying short, all created by the community. Valve also mentioned in a blog post that all of the creators will be sharing the revenue, not just the hat-makers.
