Next developmental stage of the Hydralisk [...]. If a Hydralisk is given a command to metamorph, it pupates and soon five legged Lurker come out. Lurker is a uniqe unit, because it can attack while burrowed under ground. It attacks using subterranean spines, that go through the terrain and damage any units they hit. If it´s not burrowed it may attack using it´s frontal limbs, that are equipped with long hook claws, as well as Hydralisk.
