The lurker reappeared in StarCraft II, created from a hydralisk morph, but as of February 2010 and the release of the StarCraft II beta, is no longer in the game. Not long before this, internal testing had found that the lurker had been underutilized by players. The lurker appeared at a higher tier than in the original game. Some units get a hold fire command, however, as of March 2009 the lurker did not have this ability. Lurker attacks were able to devastate groups of infantry. In addition, they could act as siege units, out-ranging conventional stationary defenses.
