StarCraft enhanced upon its predecessor Warcraft II, which highlighted two very related playable factions, by introducing asymmetry involving the models and systems accessible to its three races (Protoss, Terran, and Zerg). This asymmetry was much like that pioneered from the lesser-known 1996 SSI launch War Wind. The unit varieties available to Just about every race determine its racial id. The Protoss can field potent and pricey warriors and machinery, even though the Zerg rely on sheer quantities and pace to overwhelm their opponents.
The story focuses on the activities of a few species inside of a Element of the Milky Way often called the Koprulu Sector. Millennia in advance of any on the functions in the online games, a species often known as the Xel'Naga genetically engineer the Protoss and later the Zerg in makes an attempt to produce pure beings.[11][twelve] These experiments backfire as well as Xel'Naga are largely destroyed from the Zerg.[12] Generations right before the start of StarCraft in 2499, the hardline Intercontinental govt of Earth, the United Earth 무에타이 Directorate (UED), commissions a colonization method as Element of a solution to overpopulation.
