New boss idea.
Texas Chainsaw Killer-
Wields bushido's chainsaw, wears (scripted to be degradeable) Welder armour that keeps him from being backstabbed, but it can be destroyed.
Once it's gone, he can move faster and uses a high powered double barreled shotgun that has quite the time on reloading but fires 50-100 bullets at once.
Armour Health would be 2000, and His normal health would be 2500.
He is a normal standard speed playertype, and when his armour is gone, he can move even faster than before.
