Since when does the pickaxe have polearm blocking animations?
And any DTV hero knows that this is simply the "ballista glitch."
The way of the ballista takes many years to master. All its hidden secrets can be overwhelming for some.
I remember something similar happening in a private server in Left 4 Dead. There was a command to spawn weapons and some trolls would keep spawning them forever until framerate dropped a lot and eventually the server crashed.
Do you think it happens in DTV too?
