Undoubtedly the most important support unit of the Zerg, the Queen specializes in providing support to the Zerg mostly out of combat. It can force a target Hatchery/Lair/Hive to pop out an additional 4 larvae, which enables the Zerg quick expansion both economy and military wise. Also, an interesting fact is that the spell can be cast multiple times and you can have multiple Queens at once. It does, however, pose a serious weakness in the Zerg, because if you wipe out the opponent Zerg’s Queens his economy and military support is effectively screwed. In addition to all that, the Queen can heal friendly biological objects and can spawn a Creep Tumor which enables the Zerg to expand their area of Creep. The Queen is also an ideal option to provide early anti-air capability to the Zerg.
