Quicker than you can say "boo" - assuming you elongate it out by a few hours - Valve followed up yesterday's TF2 comic with Scream Fortress, their fifth annual Halloween event. This time around it's the Payload Race map Hightower that's been spookified, turning it into the corpse-pushing Helltower. Also: there are skeletons, and the mercs have magic spellbooks now.



"Everybody gets a spellbook gifted to them automatically, which you can equip in your Action Slot in order to pick up and cast spells," explains the TF2 blog. "The team that wins the race will be granted a buff for the final climactic battle, where you will fight for the ultimate Halloween reward: Your own lives. And a reward."



Naturally, there are a bunch of items and achievements that can also be awarded, found and bought. Scream Fortress is live now, and will run the 11th November.
