Starcraft2 Zerg Support Unit: Queen


  • The Queen is a great anti-air defense unit as well as an excellent ground unit.
  • The best thing about it is its Spawn Larva which can produce 4 extra levels in hatchery and doubles its capacity.
  • It is useful in defending the base as it can heal buildings like Spine crawlers and Hatcheries.


  • While the Queen’s low cost and low supply requirements make it a powerful unit, it is slow on the creep making it ineffective when used as an offensive unit.

Starcraft2 Zerg Support Unit: Overlord


  • The Overlord can increase the Zerg supply by 8 count.
  • Instead of sending normal units, the Overlord can be used in scouting the enemy.


  • It moves slowly but can be upgraded to move faster and transport units at the Lair.
  • The Overlord is not a detector unlike the original Starcraftbut it can be converted to an Overseer, which is a detector, after you obtain a Lair.

  • When it comes in contact with an enemy, it has the ability to disguise itself as one of the enemies and turn into the same appearance as them.
