StarCraft improved upon its predecessor Warcraft II, which featured two very identical playable factions, by introducing asymmetry concerning the models and systems available to its three races (Protoss, Terran, and Zerg). This asymmetry was similar to that pioneered during the lesser-recognised 1996 SSI launch War Wind. The unit varieties available to each race determine its racial identification. The Protoss can discipline effective and costly warriors and equipment, when the Zerg rely on sheer numbers and velocity to overwhelm their opponents.

Zeratul returns to alert Artanis of Amon's return, but he decides to progress together with his programs of major his army to reclaim Aiur. Amon awakens on Aiur and takes Charge of many the Protoss race from the Khala, the telepathic bond that unites all feelings for your Khalai 킥복싱 faction from the Protoss.
