Lurkers serve as defense warriors for hive clusters and outlying zerg colonies, but their primary role extends to supply line harassment. To attack, lurkers emit waves of super-dense spines against their enemies, having a full width of damage of ten meters. However, lurkers must actually burrow underground to release these subterranean attacks. Any warriors on the surface who are caught by these spines are instantly impaled. These spines themselves are capable of tearing into flesh, steel, and even reinforced armor plating, and can extend far from their bodies. The spines can even be directed downward into open spaces, provided the lurker is underground. As such, even a handful of lurkers can turn an innocuous chokepoint into a nightmare, and they have been known to ambush forces traveling through tight corridors and chokepoints. The spiked eruptions are sometimes so powerful that they deal seismic damage to nearby units. The spines have rarely been seen above ground, and it is unclear to many terrans where the spines actually come from in the lurker's body, although some strains can shoot spines from their frontal legs while above ground. Within the Leviathan Brood, the innate connection between hydralisks and lurkers is unparalleled among the Swarm. As such, their metamorphosis yields a considerable number of additional seismic spikes.
