StarCraft improved upon its predecessor Warcraft II, which featured two very similar 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-regarded 1996 SSI launch War Wind. The unit kinds accessible to Just about every race determine its racial identification. The Protoss can area potent and expensive warriors and equipment, even though the Zerg rely on sheer numbers and velocity to overwhelm their opponents.

The Tale concentrates on the things to do of three species inside a Section of the Milky Way often known as the Koprulu Sector. Millennia before any from the activities on the online games, a species often called the Xel'Naga genetically engineer the Protoss and afterwards the Zerg in tries to create pure beings.[11][12] These experiments backfire and also the Xel'Naga are mostly wrecked with the 무에타이 Zerg.[twelve] Hundreds of years in advance of the start of StarCraft in 2499, the hardline Global governing administration of Earth, the United Earth Directorate (UED), commissions a colonization application as Element of an answer to overpopulation.
