The Hydralisk is one of the best Zerg units becuase i ca shoot both air and ground very well. The Hydralisk is an incredibly weapon is a squad of twelve making sure that speed and attack range are upgraded otherise they pretty much suck. Hydralisk are good as the bulk of any attack force along with Zerglings or Ultralisks or some air unit. I really like Hydralisks because they are realativly cheap and they can do massive damage. Hydralisks also have the option of evolving into into Lurkers. To do this evolve the option of Lurkers at the Hydralisks Den. Then make a Hydralisk and evolve them into Lurkers. Lurkers are units that you burro even if you have not evolved Burrow. Once burrowed they become invisable except to detectors and whenever an enemy unit comes within attacking range they shoot spikes at them. They are best used in groups with Hydralisks or something else athat can shoot air because Lurkers can't.
