The Zerg Swarm are a fictional race of extraterrestrial insectoid species in Blizzard Entertainment's StarCraft franchise. They are characterized by biological adaptation, genetic assimilation, viral endemic infestation, expendable units and hive minded organization. Competing and contrasting with the human Terrans and technologically advanced Protoss, the Zerg serve as major antagonists in much of the series and become the primary playable faction in StarCraft II: Heart of the Swarm. As with the other races of StarCraft, the Zerg are the subject of a full single-player campaign in each of the series' real-time strategy video games. Zerg units are designed to be cost-efficient and fast to produce, encouraging players to overwhelm opponents through numerical advantage. New units are produced from hatcheries, while other structures unlock additional strains and upgrades. Several Zerg units also spread mutagens or use parasitic abilities, including the ability to assume control of enemy units or Terran structures and convert them into Zerg-controlled assets. The Zerg have been discussed as one of the central examples of StarCraft's asymmetric race design, and are often used as examples in broader discussions and analyses of video game balance and asymmetrical design. The terms "Zerg rush" and "zerging" have entered gaming vocabulary to describe sacrificing economic development in favor of using many cheap, yet weak units to overwhelm an enemy by attrition or sheer numbers.
Concept and creation The Zerg were designed as one of the three playable races in StarCraft, contrasting with the human Terrans and technologically advanced Protoss through an identity based on organic adaptation rather than machinery. The manual of the 1998 video game StarCraft describes the Zerg as a collective of assimilated species pursuing "genetic perfection", with their buildings, units, and starships represented as living organisms rather than manufactured technology. Originally called the "Nightmarish Invaders", they later became the "Zurg", and then renamed again to the current spelling to avoid any potential trademark conflicts with Pixar's Toy Story character of Emperor Zurg.
