Vampire hunters armed with primitive flamethrowers were a class of humans which protected the Human Citadel. They were found outside the City, trying to rid Nosgoth of the vampire scourge. They have only one kind of a short-ranged attack with the flamethrower, which needs to be recharged every few seconds. Any vampire in the vicinity of the flame would be scorched.
These vampire hunters wore a full metal mask with opening for eyes only and their whole body is covered in metal and leather. They carried a fuel tank on their backs for the flamethrower.
They can become either friendly or hostile, depending on Raziel's actions.
