StarCraft improved on its predecessor Warcraft II, which featured two pretty equivalent playable factions, by introducing asymmetry involving the models and technologies available to its 3 races (Protoss, Terran, and Zerg). This asymmetry was just like that pioneered during the lesser-regarded 1996 SSI launch War Wind. The device styles available to Each individual race outline its racial id. The Protoss can area impressive and highly-priced warriors and equipment, when the Zerg rely on sheer numbers and speed to overwhelm their opponents.

The Tale concentrates on the functions of a few species in a very Element of the Milky Way known as the Koprulu 킥복싱 Sector. Millennia before any with the activities from the game titles, a species referred to as 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 largely destroyed through the Zerg.[12] Hundreds of years ahead of the start of StarCraft in 2499, the hardline Global govt of Earth, the United Earth Directorate (UED), commissions a colonization method as Component of a solution to overpopulation.
