So, um, My fireaxe kills people on the other side of the wall, if they stand close enough. Doing this also draws everyone with a melee weapon into melee range for me to continue this until the room is empty. I have seen one time a guy leave the room, open a door and come at me from the other side. Never played melee before, so this could be an old error. I have only found three places in that map where this exploit can actually be used effectively, and one killed a blooddoll first.
