StarCraft enhanced upon its predecessor Warcraft II, which highlighted two extremely comparable playable factions, by introducing asymmetry in between the models and systems accessible to its 3 races (Protoss, Terran, and Zerg). This asymmetry was much like that pioneered within the lesser-known 1996 SSI launch War Wind. The device sorts available to Just about every race outline its racial identity. The Protoss can field powerful and highly-priced warriors and equipment, although the Zerg count on sheer quantities and pace to overwhelm their opponents.

Amon awakens on Aiur and will take control of the majority of the Protoss race through the Khala, the telepathic bond that unites all thoughts for that Khalai faction on the Protoss.
