StarCraft improved on its predecessor Warcraft II, which showcased two quite identical playable factions, by introducing asymmetry in between the units and technologies available to its a few races (Protoss, Terran, and Zerg). This asymmetry was comparable to that pioneered from the lesser-regarded 1996 SSI release War Wind. The unit kinds available to Each individual race determine its racial identification. The Protoss can area potent and costly warriors and equipment, though the Zerg rely on sheer figures and speed to overwhelm their opponents.

The story concentrates on the functions 다이어트 of a few species inside a Portion of the Milky Way often known as the Koprulu Sector. Millennia right before any of the occasions in the online games, a species often known as the Xel'Naga genetically engineer the Protoss and afterwards the Zerg in tries to create pure beings.[11][12] These experiments backfire as well as the Xel'Naga are mostly wrecked with the Zerg.[twelve] Generations in advance of the start of StarCraft in 2499, the hardline Intercontinental government of Earth, the United Earth Directorate (UED), commissions a colonization program as part of a solution to overpopulation.
