The Vanilla server has been possessed with spooky ghosts and become the haunted Halloween server once again. (Just a bit earlier)

It is currently running all previous Halloween event maps (except harvest), though there are no round or time limits enabled.

You have to be quick though, for as soon as Valve releases this years terror the server will switch to that for the duration of Halloween!

You can vote to change to another Halloween map with the usual !nominate and !rtv commands.
