If you weren't already in the Halloween spirit (which you should be), Team Fortress 2 more than has your back. I assume you've read the Halloween comic that was posted today but are still unsatiated due to the lack of game updates. BOOM! Here it is, straight from the depths of hell Valve.
This update has it all: hats, crates, and BIRD HATS! Okay, actually the Medic got a really significant buff but I just can't take my eyes off of the bird hats. Also there's a new Halloween map and mode called Helltower, a "payload race variation" that allows players to equip spellbooks and cast spells in order to win and OH MY GOSH this post is over I need to go play.
