StarCraft improved upon its predecessor Warcraft II, which featured two very similar playable factions, by introducing asymmetry 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 Every race define its racial id. The Protoss can subject highly effective and high-priced warriors and machinery, whilst the Zerg depend on sheer quantities and pace to overwhelm their opponents.

The Tale concentrates on the activities of three species within a Section of the Milky Way often called the Koprulu Sector. Millennia before any from the functions on the game titles, a species often called the Xel'Naga genetically engineer the Protoss 헬스케어 and later the Zerg in attempts to make 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 governing administration of Earth, the United Earth Directorate (UED), commissions a colonization application as part of a solution to overpopulation.
