Spawning Pool
The Spawning Pool is the first Zerg tech building; it unlocks Zerg’s basic fighting units – Zerglings. Building the Spawning pool also unlocks the Lair, Roach Warren, Baneling Nest, Spine Crawler, Spore Crawler and the Queen.
The Spawning Pool is a high priority target for the opponent, so it is advised to place it somewhere hard to reach. For most of the first year of the game, conventional wisdom dictated that the safest spot of a base was behind the mineral line. However, the increasing prevalence of drop play has suggested that the middle of the Zerg base may be safer. However, placing the Pool strategically near the mineral line can prevent enemy scouts and harassment from easily maneuvering around your workers.
Two upgrades are available at the Spawning Pool, Adrenal Glands, and Metabolic Boost.
When an upgrade is researching at the pool, the structure pulses and the surface of the pool is seen to froth.
ZERG – THE SPAWN OF THE SWARM
WILD. FATIGUE. FLEXIBLE.
Once artificially created by the mighty Xel`Naga, the Zerg would eventually lead to their demise and become a threat to the entire galaxy. Because of their collective consciousness, this species is often referred to simply as “the Swarm.” In their quest for perfection, the Zerg adopt advantageous and superior gene strands into their own gene pool, wiping out “inferior” species in the process.
Zerg Buildings
While the Protoss rely on technological superiority and the Terrans on their adaptability, the savage Zerg rely mostly on pure mass. The mostly lightly armored creatures usually pounce on their opponents from all sides on the battlefield, leaving only a picture of devastation in their wake.
