StarCraft enhanced upon its predecessor Warcraft II, which featured two extremely similar playable factions, by introducing asymmetry between the models and systems accessible to its 3 races (Protoss, Terran, and Zerg). This asymmetry was similar to that pioneered in the lesser-recognised 1996 SSI launch War Wind. The device varieties available to each race determine its racial identification. The Protoss can discipline potent and costly warriors and equipment, when the Zerg rely on sheer numbers and velocity to overwhelm their opponents.

In Legacy of your Void, Zeratul invades a Terran set up underneath Charge of Amon so as to pinpoint the precise spot of his resurrection, Making the most of a unexpected attack by Kerrigan as well as the Zerg swarm. Right after obtaining the exact location, he departs to an historic Xel'Naga temple where by he provides a eyesight of Tassadar, who prompts him to say the artifact in possession in the Terrans. Zeratul returns to warn Artanis of Amon's return, but he decides to proceed along with his options of primary his Military to reclaim Aiur. Amon awakens on Aiur and will take control of the majority of the Protoss race in the Khala, the telepathic bond that unites all thoughts to the Khalai faction 무에타이 in the Protoss.
