Overview

The Zerg are a race entirely unlike the Terrans or the Protoss. They are composed of many different species integrated into the Swarm via Zerg infestation. These creatures are rapidly and selectively evolved into deadly and efficient killers to further the driving Zerg imperative of achieving absolute domination. The Zerg make no use of technology to create their weapons, armor, or starships. Instead, these functions are efficiently fulfilled through biological adaptation and planned mutation of the Zerg strains. Even Zerg buildings are in fact specialized organs within the living, growing organism of a Zerg nest.
